Abstract
Along with China’s fast economic growth, the development of its financial sector has also attracted
with attention. After a series of reforms, the banking system remains dominated the financial sector
and impacts significantly on the country’s overall growth. In this paper, using an unbalance panel of
39 banks during the period of 2005 to 2012, we are trying to test the change of efficiency levels of
the Chinese commercial banks. The parametric approach, Stochastic Frontier Analysis (SFA) is
employed for the empirical test. In general, we concluded that in average, the efficiency level of the
Chinese commercial banks has deteriorated over the sample period and this might because of the
unfavourable economic environment in China, the unstable financial system triggered by the
financial crisis and the worsening of the European debt crisis over the past few years. Among the
various banking type, the state-owned banks were found of achieving constant improvement in their
efficiency and this might because of their bigger size and monopoly power over the market. In
addition, among the six variables which try to capture the factors which may impact on the banks’
efficiency level, four of them were found of statistically significant. They are the return to asset
ratio, the equity to asset ratio, the loan to deposit ratio and the listing status. For banks that are more
willing to accept risks, it may impact negatively on their efficiency level.
Key words: Stochastic Frontier Analysis (SFA), State-owned banks, Joint-equity commercial
banks, Chinese banking sector

Chapter 1 Introduction
1.1 Research Topic
Represented by the bankruptcy of Leman Brothers, the US financial crisis was broken out in 2007
and it has violated the stability of the world financial environment. Many of the world famous
banks have fell into financial difficulties. As the second biggest economic entity in the world,
China’s development has always attracted wide interest, in particular its financial sector. How the
system has been developed after all these reforms and how it has been influenced by the financial
crisis are some of the topics that been widely studied in recent years. As we know that after all the
reforms, China can be said of in processing of one of the biggest banking sectors in the world. By
the end of 2012, among the world’s biggest 10 banks measured by market capitalization, China
accounts for four of them. Especially for the Industrial and Commercial Bank of China (ICBC), it
is constantly been considered as the most profitable bank in the world with the largest customer
base. These banks jointly dominate the financial sector in China and therefore, the effectiveness
of the sector would impact significantly on its overall economic development.
Over the past decade, various reforms have been conducted on the Chinese commercial banks
and it was until 2010 that China has finally helped all of its state-owned banks obtained stock
listing. During the financial crisis period, the Chinese commercial banks seemed more resilient to
the negative influence from the Western world but it was claimed that it was because of their
limited exposure to the US securities (Yao et al., 2010). In future, since China has become more
and more integrated into the rest of world and its financial sector has been fully opened for
foreign competition by the end of 2006, its banking sector would inevitably subject to increased
competition and risks. How to manage these risks effectively and how to improve their
operational efficiency continuously would be the major concern for the Chinese government
nowadays. Therefore, in this paper, I am trying to shed light on these issues.
1.2 Objectives and Research Questions
Efficiency is not only one of the core theoretical questions of economic research, but also the
target of commercial banks in the actual operation and management. The efficiency of the
1
Dissertation Mingyu Xiang
banking industry not only reflects the banks’ own management performance, but also the
immanent quality of a country’s economic development. In China, the banking industry is heavily
depended on the local market, credit business and corporate business. So that is why the assets’
quality and business performance of the Chinese banks are highly relevant to its domestic
economy.
The aim of this paper is to give insight on the efficiency and risk management of commercial
banks in China to improve their efficiency and competitiveness further so as to help the banks.
On the other hand, this paper is also expected to provide empirical evidences based on Chinese
data to support the X-efficiency analysis. More specifically, there are four major objectives of this
research:
First of all, over 30 years’ reform, as the profits of the Chinese banks have increased and the non-
performing loan ratio has decreased year by year, this may indicate that the overall operational
efficiency of the banks have been improved. In this dissertation, I am planning to quantify such
improvement. To what extent has the Chinese banks improved their efficiency over the past
decade?
Secondly, Chinese SOBs (state-owned banks) were allowed to be listed on the stock exchanges
since 2005. This research also tries to find out the changes of efficiency before and after the stock
listing.
Thirdly, after China entered the World Trade Organisation (WTO) in 2001, many foreign banks
entered into the Chinese banking market. It was agreed that starting from 2007, the whole
Chiense financial market would be fully opened for foreign competition. This has resulted in a
sharp increase in the total market share and the numbers of foreign banking branches in China.
This dissertation will also test whether the efficiency of the Chinese banks would be affected by
such increased foreign appearance.
Finally, after the US financial crisis, it has been argued that a bank has to improve its risk
management capacity so as to survive in the current highly volatile financial environment. In this
dissertation, using two indicators--loan loss reserves to total loans (LLR/TL) and loans to
deposits (LD) to represent the risk exposure of the banks’ loans--I am also planning to find out
2
Dissertation Mingyu Xiang
the relationship between banks’ efficiency and their risk management.
Based on these four objectives, the following research questions will be addressed in this
dissertation:
How the recent financial crisis has influenced the efficiency of the Chinese commercial
banks?
Whether the ownership structure of the banks is still able to influence their efficiency?
Whether the foreign banks could maintain a higher efficiency than the Chinese domestic
banks once they entered into the country?
What is the change of efficiency level of the Chinese banks over recent years?
If the bank is willing to take more risks, would this act positively on its efficiency?
1.3 Structure of the Dissertation
This dissertation is comprised of six chapters. In the first chapter 1, the research topic, objectives
and research questions will be introduced. Then in Chapter 2, a comprehensive background
review about the development of the Chinese banking sector will be presented. In particular, the
current situation of the Chinese banking system and the impacts of increased foreign entry on the
Chinese commercial banks will be discussed. Chapter 3 will first define the meaning of x-
efficiency, and then a detailed review about the existing literatures on banks’ efficiency will be
conducted. Chapter 4 will compare the two efficiency measurement techniques, the parametric
approach, Stochastic Frontier Analysis (SFA), and the non-parametric approach, Data
Envelopment Analysis (DEA), and the discuss their relative advantages and limitations. In
addition, the variables used in this study will also be defined and discussed. Chapter 5 will
conduct the empirical analysis and then summarise the findings. The last chapter 6 will conclude
the whole paper, talk about the limitations of this research and also propose some policy
implications based on our tested results.

Chapter 2 Background Review and Development of Chinese Banking Sectors in China
When China was established in 1949, it could be said of adopted a mono-bank model which can
be characterised as of having highly centralised power and unified management. According to
Allen et al (2005), during that period, the People’s Bank of China (PBOC) was also the only bank
in China. It served as both of the central bank and a commercial bank. It carried out two roles, the
commercial operations and policy lending simultaneously. The bank controlled about 93% of the
total financial assets and almost 80% of the deposits of the country during the following
approximately 30 years. Since 1978, this situation has been gradually changed in accordance with
the country’s comprehensive economic reform. As stated by the central government, the major
target of the Chinese banking reform was to establish a modern banking system which could
provide the needed support to the country’s economic reform. It aims to restructure the whole
sector to become more diversified, competitive and profit-driven (Yao et al., 2007). This Chinese
banking system reform was directly related to the country’s overall economic and financial
development. It has played a crucial role in improving financial resource allocation efficiency and
consequently assisted the enhancement of overall economic efficiency and the opening-up policy
in China (Fu & Heffernan, 2007). Up to now, four stages of reform have been implemented:
Initial stage: 1974 to 1984
The first structural reform began in 1974 and ended in 1984. The mono-bank system was changed
to a two-tier banking system gradually. It meant that the central bank and the commercial banks
were separated and the PBOC was no longer the only bank in China. Indeed, during the same
time, the banks’ system reform has also been promoted. One is the gradual establishment and the
completion of the functions of the central bank and the other was to set up a system for the
commercial banks.
The second stage: 1985 to 1994
The second stage of banking reform lasted about ten years from 1984 to 1994, during which the
“Big Four” SOBs had gained a certain level of independence and the overall banking system had
become more diversified. However, according to Allen et al (2005), although the reforms
focusing on the financial system had achieved significant improvements and the market was
4
Dissertation Mingyu Xiang
opened up for new competitors, activities of the Chinese commercial banks were still subject to
various influences from both the central and local governments. Therefore, proper legal and
regulatory systems needed to be established. In addition, this period also witness the emergence
of the joint equity commercial banks (JECBs) across the country.
The third stage: 1995 to 2001
The third stage can be characterised as the deregulation period across the banking system. Since
1997, the Asian financial crisis, the Chinese government started to realise the importance of
banking commercialisation. It has therefore adopted some positive policies, such as the
establishment of China’s two stock exchanges, the promotion of continued commercialisation of
the SOBs and the construction of multi-level and multi-type financial institutions.
The fourth stage: 2002 to present
Since 2001, when China joined the World Trade Organisation (WTO), the banking system reform
could be said of being pushed into the fourth stage. This is also a critical period as the entrance of
WTO has created more incentives for the Chinese banking sector to become more competitive,
innovative and efficient. Starting from 2002 the Chinese government has implemented drastic
reforms on the regulation of the SOBs, JEOBs, city commercial banks (CCBs), rural financial
institutions and the foreign banks. In addition, the Chinese Commercial Banking Law was issued
in 1995. This was the first time that the commercial banks’ rights and obligations were specified
clearly in legal form. Since then, banking system has been strengthened on internal management
and risk control. In 2003, the China Banking Regulatory Commission (CBRC) was founded.
After that, the Big Four SOBs began to join the share-holding reform and finally were listed on
the stock market successfully.
Although the reform is still ongoing, at this point great changes have been achieved across the
Chinese banking industry. The state only maintained full control over three policy banks while
other banks tend to adopt a mixed ownership structure. It is not necessary for the central or local
government to be the major holder in these banks. Meanwhile, the Chinese banking sector has
been transformed from the one that was government-driven to the one that is market-oriented.
Although market-oriented reform of interest rates and exchange rates may lead to heightened
5
Dissertation Mingyu Xiang
market risks, it is imperative that China’s banking industry transforms its past operating model
and reshapes its banking structure to achieve sustainable development in the future.
During the fourth stage of the banking reform, the modern multi-tier framework has almost been
established with various financial institutions coexisting in the system. The current structure of
the Chinese banking industry can be demonstrated by Figure 1.
Figure 1 China’s Banking Overview 2007
Based on the statistics of the CBRC’s annual report (2007), by the end of 2006, there were
approximately 343 commercial banks existed in the Chinese banking industry. It consisted of five
SOBs, 12 JSCBs, 113 CCBs, almost 200 foreign banks and 13 rural commercial banks. After
nearly 30 years’ reform and development, all the Chinese commercial banks have been improved
to a greater or less extent, in particular the SOBs. They have made significant improvements been
transformed into shareholding companies, and finally been listed on the stock exchanges
successfully during 2006 to 2008. By the end of 2012, a total of 16 Chinese commercial banks
had been listed on the stock exchanges successfully. It includes four SOBs, eight national JSCBs,
three CCBs and one rural commercial bank (RCB).
The 2008 U.S. sub-prime mortgage crisis and the recent European debt crisis have put the global
6

Dissertation Mingyu Xiang
economy into difficulties. There were many uncertain factors in the macroeconomic environment.
Because of the negative impact of the U.S. financial crisis, the Chinese banking industry faced
more severe risks and challenges under the current international macroeconomic environment.
These may include credit risks, operational risks, liquidity risks and legal risks. With the market
risks continuing to emerge, the CBRC (2009) said that China’s banking industry would endeavor
to deliver constant superior performance, consolidate its own development, further deepen the
banking reform and strengthen the banks’ overall management in the coming years. Since the
Chinese government has taken a cautious attitude towards the opening policy of the financial
industry, only six listed Chinese banks were found to be in the possession of a small amount of
the US subprime mortgage bonds. It was reported that more than 95% of the revenue and profits
of the Chinese banks were generated from the domestic market. Therefore, although the financial
crisis has influenced the Chinese banking industry negatively, the banks’ liquidity position has yet
been seriously damaged. That explains why the Chinese banking industry was able to avoid the
financial tsunami that hit. In the next part, with reference to the different ownership structure of
the banks, I will talk about their reform process one after the other.
2.1 State-owned Banks
Since 1979, the Chinese government has been constantly pushing the gradual and wider market-
driven banking reform program. The PBOC used to be the only central and commercial bank in
China. During 1979 to 1984, the commercial functions of the PBOC have gradually taken over by
the “Big Four” SOBs. After that, the PBOC acted exclusively as a central bank which was an
effective resource allocation mechanism in the central-planning economy. It was mainly
responsible for implementing monetary policy and supervising the financial system and all other
financial institutions under the regulatory framework (Fu & Heffernan, 2007). In order to
improve the production and operational efficiency, the Chinese government established four
state-owned specialised banks to replace the commercial banking functions of the PBOC. They
included the Agricultural Bank of China (ABC), the Bank of China (BOC), the China
Construction Bank (CCB) and the Industrial and Commercial Bank of China (ICBC). To serve
the specific needs and support the developing strategies, these newly set up SOBs were specified
7
Dissertation Mingyu Xiang
with different functions (Yao et al., 2008). For instance, the main domestic business of the ABC
involves engaging in rural financial services, providing funding needs for agricultural related
sectors, cooperating closely with rural cooperative financial organisations and promoting the
integrated development of the rural financial system. It also provided wholesale and consumer
banking services to farmers, townships, village enterprises and other rural institutions (Yao et al.,
2008). The CCB was in charge of the management and allocation of financial resources to urban
construction projects. In addition, it was also responsible for providing funds, medium and long-
term loans to support the urban building, engineering projects and housing development in China.
The ICBC is the biggest specialised state bank in China measured by various aspects, such as
total customer number, total employees and total assets. The main business of the bank included
providing financial resources for urban industrial and commercial business, as well as settling
international transactions (Chiu & Lewis, 2006). And finally, the BOC was a dominant foreign-
exchange bank. It was designed to be responsible for unified management and centralized control
of foreign exchange business throughout the country, such as foreign exchange rate setting and
the development of international transactions. In order to provide more convenient services and
deliver superior value to the customers, each of the “Big Four” SOBs had established a large
number of branches across all key cities, municipalities and overseas.
With the establishment of the four SOBs, the Chinese banking system reform had been pushed
forward into the next stage. However, many problems of embedded in the system started to
emerge. Although the operation of the SOBs had been separated from the PBOC’s, they remained
controlled by the Chinese government. Long-term government intervention has made the
operation of the SOBs depend highly on the government. The production and operational
efficiency of the SOBs were quite low and there was virtually no competition within the system.
According to the government’s instructions, the SOBs tended to provide more services to the
state-owned enterprises (SOEs). For instance, the loan and fund applications from the SOEs were
normally treated with priority above the applications submitted by the other types of companies.
Moreover, the interest rates offered to the SOEs were again more favorable and no late payment
punishment was imposed on them. Consequently, since the SOEs were mostly government-
related organizations and they care little about their own profitability, this resulted in the four
SOBs accumulating a large amount of non-performing loans (NPLs). If this problem could not be
8
Dissertation Mingyu Xiang
solved, it was hard to achieve the reforming target of banking commercialisation, enterprisation
and marketisation.
To solve this issue, the government adopted two approaches. The first one was the establishment
of three policy banks in 1994. They were the Agricultural Development Bank of China (ADBC),
the China Development Bank (CDB) and the Export-Import Bank of China (China Ex-Im Bank).
The ADBC’s primary function was to provide financial supports to China’s agricultural
institutions and its rural residents. The core function of the CDB was to provide financial services
to major development projects, such as infrastructure projects. The China Ex-Im Bank, as
suggested by its name is responsible for facilitating the import and export of Chinese capital
goods. It was expected that once these policy banks had been founded, they would release the
SOBs from engaging into policy lending activities. Then the operation of the former four
specialized SOBs could become purely driven by the market and may could be transformed into
real commercial banks. However, after all these reforms, it was found that the original intention
of separation of commercial and policy lending activities of the banks was hard to be fully
achieved. This was mainly because during the early period, the four SBOs had already
established lots of branches across the country with easy access to local customers. It was almost
impossible for the three new policy banks to expend their network as widely as the SOBs (Luo et
al., 2011). As a result, local governments still preferred to go to the four SOBs for their finance
needs. Therefore, the establishment of the three policy banks did not help remit and solve the
problems of non-performing loans (NPL) significantly.
In 1997, a serious Asian financial crisis was broken out. This has forced the Chinese government
to realize that a large amount of NPLs and weak risk management are the key risk factors
embedded in the Chinese banking system. If the NPLs continue to grow rapidly, it may lead to
banking crisis. Based on the statistic of (Yao et al., 2007), by the end of 1997, the total assets of
the four SOBs were RMB 8.72 trillion, but their liquidity assets was only about RMB 0.31
trillion. This has made their capital to risk-weighted assets ratio (CRAR) equal to 3.5%, a level
which was much lower than the 8% requirement set by Basel I. Therefore, the huge amount of
NPLs and a severe shortage of capital suggest that the next stage of reform could not be carried
9
Dissertation Mingyu Xiang
on. The establishment of three policy banks could not reduce the NPLs of the big four effectively.
The Chinese government has to adopt a second method that was to inject money directly to help
them solve the bad debt issue and improve their asset quality. In order to help the financial
restructuring of the four SOBs and prepare for the WTO entry, four Asset Management
Companies (AMCs) were set up in 1998. They are China Asset Management Company, China
Huarong Asset Management Company, China Great Wall Asset Management Company, and
Oriental Asset Management Company. They are responsible for managing and recovering the
NPLs transferred from the four SOBs, as shown in Table 1.
Table 1 Non-Performing Loan Transfers of 1999-2000

In 1999, with a total NPL of RMB 2.5 trillion, the Chinese banking system was virtually
insolvent. This has pushed the government to stripe off RMB 1.4 trillion NPLs from the four
SOBs in 1999. However, despite the stripping off, the average NPLs ratio of the four SOBs
remained high at 20%. To help the Chinese financial sectors reach the international standards, to
create a favorable investment environment, and to get ready for the WTO entry, the NPLs of the
four SOBs need to be further disposed off by the central government. This could be summarized
in Table 2. The second round of NPLs disposal could be said of happened during 2003 to 2004. A
total of RMB 475.6 billion bad debts were stripped off from the BOC and the CCB. By the end of
2005, almost RMB 2.6 trillion NPLs of the SOBs were stripped off (Garcia-Herrero & 10
Dissertation Mingyu Xiang
Santabarbara, 2008).

Since China joined WTO in 2001, the Chinese market was opened gradually to the rest of the
world. In order to cope with increased international competition and enhance the Chinese banking
sector’s own competitiveness, the Chinese government implemented shareholding reforms on the
‘Big Four’ while continuing restoring their financial health. The shareholding reform was first
conducted on two pilot banks, BOC and CCB, and the government pumped an additional $ 45
billion into these two banks in 2004. During the following year, the ICBC implemented
shareholding reform with registered capital of RMB 248 billion. It was until 2008, that the
shareholding system reform of the “Big Four” SOBs could be said of formally completed. The
last one, ABC got RMB 130 billion capitals and the approval from the State Council about its
shareholding reform plan in 2008 (Luo et al., 2011). Through the implementation of the
shareholding system reform, the asset quality and profitability of the SOBs have been improved
significantly. This has greatly assisted the enhancement of the financial sustainability across the
whole system. By the end of 2009, the CRAR of the BOC, CCB and ICBC are 11.7%, 11.14%
11
Dissertation Mingyu Xiang
and 12.36% respectively. Meanwhile, just one year after the shareholding reform, the CRAR of
ABC has also been improved to over 10% and the bank has made RMB 65 billion worth of net
profits (Bank scope, 2013).
With the stripping of the NPLs and the shareholding reform of the banking system, the country’s
banking industry has been transformed into a customer-orientated market with multiple capital
structure. The country’s financial environment has been improved significantly and become more
attractive to the foreign investors. Starting from 2005, the four SOBs welcomed its overseas
strategic investors successively. CCB was the first SOB which introduced its strategic investors.
In June 2005, the Bank of America (BOA) invested $ 3 billion to acquire 10% share ownership of
the CCB. It has also signed agreement to cooperate with CCB in the field of seven areas, such as
corporate governance and risk management. Later in the year, BOC also received a total
investment of approximately $ 3.67 billion from three foreign investors, Royal Bank of Scotland,
Swiss Bank Corporation (SBC) and the Asian development bank (ADB). As a result, the
ownership structure of the BOC has been changed into 15.47% of foreign shareholding and
84.53% of domestic shareholding. Table 3 summarises the foreign strategic investors of the four
SOBs and their areas of cooperation.

After all the preparation, the central government began to list the SOBs in both Hong Kong and
Shanghai stock exchanges. It is believed that once the stocks of the four SOBs went public, it
would help the bank to improve their performance and capital structures, establish an incentive
mechanism within the SOBs, and enable them to raise funds from a more diversified background.
In 2005, the first listed SOB was CCB. It issued 26.5 billion shares on the Hong Kong stock
exchange (HKSE) and raised approximately $ 8 billion (Mitchell, 2006). In the following year,
BOC listed on both of the Shanghai Stock Exchange (SSE) and HKSE successfully. The initial
public offering (IPO) of BOC raised $ 11.2 billion and it was larger than the world’s biggest
public share offering during that six-year period. The IPO of ICBC was conducted in both of the
SSE and HKSE in October 2006. It helped bank get $21.9 billion funds and set up a new world
record. After the shareholding reform and stock listing, the size and ownership of the four SOBs
has been changed and it could be summarized in Table 4.

Since the outbreak of the U.S. subprime crisis in 2008, the global financial environment has
entered into an extremely volatile period. However, since the central government still retained the
majority control of the four SOBs and adopted a prudent investment approach, these banks have
not been severely damaged by the 2007-2009 global financial crisis (Allen et al., 2012). In
particular, according to the study of Berger et al (2009), the strategic investors were good at
improving the operating performance of the SOBs. In addition, the HKSE LISTING OF THESE
SOBs were the other important step in reforming them and consequently made they outperform
may large banks from emerging and developed countries during the 2007-2009 crisis period.
Suggested by Allen et al (2012), the four SOBs displayed superior and stable performance during
the financial crisis period. For instance, the IPO of ABC raised over $22 billion from SSE and
HKSE during the post-2008 global financial crisis period. In 2008, ICBC achieved a total profit
of RMB 111.2 billion, representing an increase of 35.2% from a year earlier (Hawser, 2009). In
the meantime, the net profits of BOC and CCB have also increased by 14.4% and 34%
respecting, reaching the RMB 92.6 billion and RMB 64.4 billion respectively (Piggott, 2009).
Therefore, based on the statistics of the Banker (2009), three of China’s SOBs were now among
the world’s top five most profitable banks. Table 5 summarizes the changes of NPL ratio and
ROA ratio of the big four SOBs over the period of 1999 to 2012. It shows clearly that they now
14
Dissertation Mingyu Xiang
have a much healthier balance sheet and generate much higher profits, in particular after they
have been listed on the stock markets. It is worth to be noted that even during the financial crisis
period, these Chinese SOBs were managed to reduce their NPL ratios and enhance their
profitability continuously.

Unfortunately, despite making a higher ROA ratio and in processing of limited amount of the US 15
Dissertation Mingyu Xiang
sub-prime mortgages, share price of these four SOBs were still badly hurt during the crisis
period. As can be seen from the Figure 2 below that after reaching a record high in 2007, share
prices of all these fours SOBs plummeted and remained low afterwards. None of them has
recovered to the pre-crisis level even until today. Recently, the slowdown of the Chinese overall
economy has imposed additional pressure onto the banks. Facing increased foreign competition
and the changing operational environment, how to survive and remain profitable have become
key challenges to the Chinese commercial banks in the near future.

2.2 Joint Equity Commercial Banks
The second category of the Chinese commercial bank is joint stock/equity commercial banks
(JECBs). It could be regarded as the new source of competition created by the central government
in the banking industry. Compare with the SBOs, the JECBs were smaller and normally have
multi-ownership structure. Stating from 1985, many JECBs were established national wide under
the consent of the State Council of People’s Republic of China (PRC). The first domestic JECB
was the Bank of Communication (BOCOM) and it was established in 1986. One year later, the 16
Dissertation Mingyu Xiang
Shenzhen Development Bank (SDB) and the China Merchants Bank (CMB) were founded. In
1991, the SDB was successfully listed on the Shenzheng Stock Exchange (SZSE) (Lin & Zhang,
2006). In 1988, the Guangdong Development Bank (GDB) was set up and it has become a
shareholding bank listed on the SZSE successfully in 1992. It had three main shareholders,
including that are the BOC Group in Hong Kong, the Hong Kong Chinese Banking Group and
the Ministry of Finance. In 1996, the China Minsheng Bank (CMINB) which was also the first
privately funded bank was established. All of its shareholders are non-government entities. In the
meantime, some other JECBs such as China Everbright Bank (CEB), Huaxia Bank (HXB), China
CITIC Bank, Shanghai Pudong Development Bank (PDB) and Fujian Industrial Bank (FIB) have
also been founded. Table 6 presents the equity structure of the 12 JECBs by the end of 2010.
Table 6 Shareholdings of China’s JECBs

Note: Data for Evergrowing Bank is for 2009. 2010 annual report not available
The shareholding structure and the number of shareholders of the 12 JECBs varied. For instance,
the CMINB reported that the bank had 1,123,423 shareholders in 2010 while the China Bohai
Bank was only reported of having seven shareholders during the same period. Since the majority
of the JECBs were established after the initiation of China’s banking reform, they tended to have
a lower level of government ownership and were expected to be responsible for their own
financial performance. Such market driven nature has led the JECBs to generate higher profits
and have better asset quality. As shown in Table 7, compared with the SOBs, the NPL ratio of the
JECBs was constantly lower than that of the SOBs.

Similarly, after the implementation of the open up policy in China, the JECBs have also attracted
a large number of foreign investors and seven of them had also achieved stock listing on both of
the HKSE and SSE over the past decade. In recent years, they have become more and more
important in the Chinese banking sector and imposed lots of pressure to the SOBs. According to
the statistics of the CBRC’s Annual Report, the 12 JECBs have got RMB 23.5 trillion total assets
and 17.61% of the market share in banking industry by the end of 2012.
2.3 City Commercial Banks
The City Commercial Bank (CCBs) is regarded as the ‘third tier’ of the Chinese banking system.
Since 1979, a large number of urban credit cooperatives (UCCs) were founded in many major
cities. They were designed to assist the SOBs providing financial services to the local small-and
medium-sized enterprises (SMEs) and household and promoting the local economic
development. However, alone with continued banking reform, many potential problems started to
emerge, including low productive efficiency, weak internal management capital adequacy ratio
and the relative small size but high risks. In order to solve these accumulated problems, about
5,000 UCCs were merged and restructured into CCBs during the 1990s by the city governments.
In 1995, the Shenzhen City Commercial Banks, which was also the first CCBs in China, was set
up. By the end of the initial restructuring period, about 3,240 UCCs were transformed into 88
CCBs by 1998. When the CCBs were first established, their business operations were confined
within their city boundaries and were only allowed to set up branches inside of their respective
19
Dissertation Mingyu Xiang
cities (Han, 2000). This has also made the CCBs more vulnerable to the increased market
competition. Meanwhile, CCBs were mainly controlled by the local governments. According to
the research report of KPMG (2007), in average, 75% shares of the CCBs were taken by local
governments, and around 70% of the loans were used to support the operation of the four SOBs
and private SMEs.
Due to the poor risk management, government-driven operation and limited market penetration,
the CCBs have encountered even greater problems than the four SOBs in terms of high NPLs
ratios and poor capital adequacy ratio during the period of 1990s. In particular, some CCBs were
estimated to have a NPL ratio of over 50% (Martin, 2012). In 1998, to reduce the NPLs and
attract foreign investors along with the open policy, the state council decided to restructure and
transform the CCBs into shareholding organisations. In 1999, Bank of Shanghai received $ 220
million foreign investment from the International Financial Corporation (IFC) and became the
first CCBs with foreign investors strategic. However, since the IFC was not a commercial bank, it
was unable to provide the needed experiences which could assist the bank realising business
integration. In December 2001, the Hong Kong and Shanghai Banking Corporation (HSBC)
purchased 208 million shares of Bank of Shanghai, accounting for 8% of the bank’s ownership.
This was the first case for a foreign-funded commercial bank to become a shareholder in a
Chinese domestic bank. Since 2005, the CCBs started to invite national and international private
institutions to take shares of the banks widely. By the end of 2007, about 12 CCBs were
restructured with at least one foreign investors sitting on the board of directors, as summerised in
Table 8.
Table 8 Foreign Investment in Chinese City Commercial Banks

The foreign investors did not only bring in additional capitals to the CCBs, but also advanced
technologies and management experiences. In the meantime, the ownership structure of the CCBs
was further diversified with more private enterprises and individuals becoming key shareholders
of the banks. Table 9 listed the shareholding structure of five samples CCBs. Consequently, the
improvement in risk management, the implementation of asset restructuring programs and the
injection of foreign capitals have all helped the CCBs achieve high profits and lower average
NPLs ratios. By the end of 2006, the average NPL ratios of all the CCBs were reduced from
17.72% in 2002 to 4.78% (Wong & Wong, 2001).

With the domestic financial market fully opened up the central government and CBRC relaxed
the geographic restrictions imposed on the CCBs, allowing them to operate and establish
branches outside of their respective cities. It aimed to enhance the CCBs’ competitiveness and
help them gain additional market share in the overall banking system. In April 2006, the first
cross-regional CCBs branch was set up by the Bank of Shanghai in Ningbo (Tan & Fu, 2007).
The CCBs have gradually expanded their business scope and started to play a more important
role in urban economic development. From 2007 to 2009, the CBRC issued many new policies,
such as the ‘Notice on Adjusting the Licensing Policies for the Branching by Small and Medium-
Sized Commercial Banks (Tentative)’. It granted the CCBs with more autonomy allowing them to
set up branches in western and northeast regions and also removing the limitations on their
operating funds. These policies stimulated the fast expansion of the CCBs. Consequently, the
Bank of Jinzhou established a branch in Tianjin; the Bank of Chengdu set up a branch in Chongqi
and the Bank of Zhengzhou built a branch in Nanyang (Wang et al., 2008). According to the
statistics of CBRC, by the end of 2010, 62 CCBs have carried out their cross-regional
development and established 103 branches in other citites.
After a series of reform and policies incentives, the growths of the Chinese CCBs have
accelerated. In 2007, three CCBs Bank of Beijing, Bank of Ningbo and Bank of Nanjing were
listed on the Stock Exchange successfully. Alone with the fast development of the CCBs and the
introduction of more favorable IPO norms by the government, over 40 CCBs were now on the
waiting list of going public. According to the statistic of CBRC, by the end of 2010, 43% of the
CCBs share was hold by private nonfinancial institutional investors, while only 18.5% of their
22
Dissertation Mingyu Xiang
shares were remained controlled by the local government. In the meantime, the CCBs have alos
developed their own strategic alliance network. For instance, as early as 2001, six CCBs,
Shenzhen, Nanjing, Guiyang, Wuhan, Hangzhou and Dalian have developed a strategic
cooperation framework. And later in May 2004, led by Nanjing City Commercial Bank, another
15 CCBs were aligned to establish two investment centres for inter-banking securities capital. All
these policu stimulated the fast expansion of the CCBs. As shown in Figure 3, total assets of
CCBs have reached RMB 45.638 trillion by the end of 2012, accounting for 9.24% of the whole
sector.

2.4 Foreign Banks Entered into Chinese Banking Market
Since China started the economic reform from the late 1970s, the foreign banks were allowed to
enter into the Chinese financial market. Before joining the WTO, the development of the foreign
23
Dissertation Mingyu Xiang
banks went through five stages. In 1979, the Export-Import Bank of Japan was allowed to
establish a representative office in Beijing. After that, some major and more meaningful
developments were carried out mainly focusing on three aspects. At first, starting from 1982, the
foreign banks were approved to open operational branches in Special Economic Zones (SEZs).
Later, the Nangyang Commercial Bank founded the first foreign bank branch in Shenzhen. Then
during the 1990s, the central government expanded the operation scope of the foreign banks to
include more cities. In August 1994, eleven inland cities were opened to the foreign banks,
allowing them to set up representative offices and operational branches. It was 1999 until taht the
geographic restrictions of branches setting on foreign financial institutions were fully cancelled
(Chen, 2000). Finally, the Chinese government further relaxed policies which allowed that allow
eligible foreign banks conducting local currency business in Shanghai and five designated
provinces in 1999. By the end of 1996, foreign banks from 15 countries have established their
branches in China (Leung et al., 2003). The Table 10 shows the total assets and the number of
foreign banking branches during the period of 1985 to 1996.
Table 10 Number of Foreign Banks, Branches and Assets during 1985 to 1996

Since China joined the WTO in 2001, to supervise the foreign banks more effectively, the central
government started to remove and revise its original banking industry regulations, and
promulgate new rules and policies. For instance, the ‘Content and Time of Chinese Financial
24
Dissertation Mingyu Xiang
Institutions Opening after Entering WTO’ and the ‘People’s Republic of China Ordinance on
Management of Foreign Capital Institutions’ were promulgated by the State Council in 2001.
Furthermore, to fulfill WTO agreement, CBRC raised the ‘Foreign-Funded Financial Institutions
Regulations of the PRC’ in 2004 and relaxed various restrictions imposed on the foreign banks,
such as their business scope and geographical locations (Serrado & Sabadell, 2003). For instance,
in 2001, the foreign banks were only allowed to offer the RMB business to local enterprises in
four coastal cities including Shanghai, Shenzhen, Tianjing and Dalian One year later, the
restriction has been removed in another five cities. Then two-year later, Jinan, Fuzhou, Chengdu
and Chongqi were further opened up. During 2004 and 2005, another seven cities were followed
to implement the opening up policy. And finally in 2006, all the geographic restrictions were
cancelled and the whole Chinese financial market was fully opened for foreign competition. After
deregulation, more and more foreign banks stared to enter into China.
There are four main modes that the foreign banks would choose when they enter the banking
market in China. They were establishing foreign branches, establishing the wholly foreign capital
banks, setting up joint-capital banks or holding share and acting as the strategic investor of the
Chinese domestic banks. Before the Chinese market has been fully opened up, the last mode was
the preferred method. It could be explained by four reasons. First of all, before the 2001 WTO
entry, favorable policies on the Chinese domestic banks helped them in extensive presence and
have made the direct market penetration by the foreign banks hard to achieve (Leigh & Podpiera,
2006). Secondly, cooperate with the domestic banks may help foreign banks obtain interests
protection. Many foreign banks tended to purchase shares in small and medium-size banks to get
a controlling position. Then using such favorable position to get their business expanded further
and to obtain higher yield from China’s fast developed economy. Thirdly, as the strategic
investors, the foreign banks were allowed to participate in the management of the domestic
banks. It provided a platform to help the foreign banks understand the Chinese market, obtain
some local contacts and get ready for further expansion. Last but not least, before 2006, many
restrictions were set up to limit the activities of the foreign banks and this has left them with no
choice but to enter the Chinese market as a strategic investor. It helped them save time and a large
amount of costs for the entering process. According to the CBRC’s regulation on foreign 25
Dissertation Mingyu Xiang
investment, their combined ownership of a Chinese commercial bank was not allowed to exceed
the threshold of 25%. Consequently, all these policies have effectively protected the domestic
financial sector and ruled out the competition.
During the post-WTO period, many foreign banks purchased shares of the domestic banks
successfully and have become their strategic investors. These cases included Citigroup’s purchase
about 5% ownership of Shanghai Pudong Development Bank (PDB) and Hang Seng Bank
Ltd.and IFC etc’s joint purchase of 24.98% share in Industrial Banks in 2003. In December 2005,
the first Chinese commercial bank born with foreign minority stake. China Bohai Bank was
established with 19.99% share owned by Standard Chartered (Berger et al., 2007). By the end of
2004, the foreign investors were found of in owning $ 17 billion shares of the Chinese banking
sector. Table 11 listed all the foreign investment into the Chinese banking sector.
Table 11 Foreign Investors in Chinese Banking Industry

Since 2006, when the foreign banks were allowed provide similar range of services as the
domestic banks, setting up foreign banking branches have became more popular among the
foreign banks. Table 12 illustrates the development trend of the foreign banking institutions in
China. The total assets of the foreign banks presented sustained growth from 2004 to 2011. The
total assets have increased almost four times from the 2004 level in 2011, reaching RMB 2.15
trillion. Meanwhile, they have also obtained sustained increase in profits, mainly a total of RMB
16.7 billion net profits in 2011.

Based on the statistics of CBRC, by of end-2011, there were 181 foreign banks and 209
representative offices from 45 countries were established in China. However, as the Table 12
above demonstrated that although the foreign banks’ total assets and number of institutions have
increased, continuously, their combined assets as a percentage of the total assets of the China
banking industry were actually decreased slightly from 2.38% in 2007 to 1.93% in 2011. Over 40
foreign banks injected additional capital which was equal to RMB 27.1 billion to expand their
business in the Chinese market (CBRC, 2011). The Chinese government adopted a welcomed
attitude for the growth number of foreign banks and their branches. As it is believed by the
central government that they will generate some positive impacts on the Chinese banking
industry, such as forming a healthy competition environment, improving domestic efficiency and
risk management consciousness.
Chapter 3 Literature Review
3.1 Define Efficiency and X-efficiency
Generally, the efficiency is a proportional relationship between the outputs and the inputs of time,
costs or efforts. The concept of X-efficiency was proposed by economist Harbey Leibenstein in
1966. In the banking environment, the X-efficiency could be regarded as the ability of a bank to
28
Dissertation Mingyu Xiang
achieve a maximum of output for a fixed amount of input. There are two ways to achieve highest
efficiency. One is using minimum input to obtain a certain amount of output while the other is
getting the maximum amount of output by a certain amount of input consumed.
There are two main types of X-efficiencies, the cost efficiency (CE) and profit efficiency (PE). In
particular, the cost efficiency is more likely to be use in the banking research as decisions related
to cost control are more likely to be controlled by the management. The CE could then be further
classified into two categories, including the technical efficiency (TE) and the allocative efficiency
(AE). The TE only takes the quantity into account. It was first put forward by Farrell in 1957 and
been improved by Leibenstein in 1966. A bank could be said of achieved full technical efficiency
if it could produce the maximum amount of outputs for a specified amount of inputs, including
labor, capital and technology (Yao et al., 2007). In the AE, Price is the core issues and plays a
guiding role in the allocation of resources. It focuses on whether the banks could make the best
combination of the input resources and output products facing fixed market prices. As a result,
both TE and AE should be considered in the cost efficiency analysis. This is mainly because if
two companies use the same amount of input and obtain same quantity of output, their TE are
identical but their AE may not be the same as the price of the input resources and outputs could
be different. Therefore, the calculation of the cost efficiency of the banks could be represented by
the equation below:
CE = AE * SE (Scale efficiency) * TE
3.2 The Frontier Methods for X-efficiency Study
The efficient frontier analysis is more commonly used in economic and operational research
nowadays. It aims to measure the input-output efficiency of the observations. Compared with
simple ratio analysis, the frontier analysis methods have a series of advantages. For instance, it
allows the use of a variety of indicators and encourages the use of some non-traditional measures.
So the results of the frontier analysis methods can figure out whether a chosen company can be
said of displaying outstanding performance compared with its peers based on a series of different
indicators. The frontier analysis methods mainly consist two main categories, the parametric
29
Dissertation Mingyu Xiang
(econometric) and the nonparametric (mathematical) approach. For the parametric frontier
approach, it mainly includes stochastic frontier approach (SFA), distribution-free approach (DFA)
and thick frontier approach (TFA). The nonparametric frontier approach generally includes two
types of methods, data envelopment analysis (DEA) and free disposal hull (FDH). Parametric
approach and nonparametric approach are two broad classifications of the statistics procedures.
The major differences between the two approaches include the use of data and variables, the
hypothesis about the construction of the efficient frontier and also the assumptions about the
distribution of the error random and managerial inefficiencies. For instance, the data distribution
is significant different between the parametric and the non-parametric procedures. Among these
methods, the SFA and DEA are the most widely used ones.
Although both of the DEA and SFA are frontier methods, they have a series of differences. For
instance, the SFA model is constructed based on a series of strict hypothesis. A production
frontier, such as the Cobb-Douglas functional form or the Translog form needs to be assumed for
the production process and the error term is comprised with two elements. For the random error,
it is assumed to follow a standard normal deviation while for the managerial inefficiencies, since
it is non-negative so it is assumed to follow a half-normal distribution. All these pre-specified
assumptions have made the estimation process more complicated and are criticised of misleading
if they are unable to capture the real picture of the production process or the distribution of the
error terms. Compared with SFA, no the non-parametric approach, DEA has much less
restrictions imposed on the frontier functional forms. The efficient frontier, or the production
frontier of DEA is created based on the observations within the sample and it assumes that there
is no random error. Consequently, all the deviations from the “best practise frontier” are
interpreted as inefficiencies and this has made the estimated DEA efficiency scores lower than the
ones estimated by other methods.
The second difference between the DEA and SFA lies on their use of variables. Due to various
restrictions imposed by the SFA method, the choice of data and variables used for estimation is
difficult. If the distribution of the chosen variables is wrongly assumed, it may lead to biased 30
Dissertation Mingyu Xiang
estimation. Consequently, the DEA model is easier to be expended and transformed into more
advanced models.
Last but not least, the robustness of the estimated results is different between the two methods.
Under the DEA estimation, the “efficiency frontier” is comprised with the DMUs that are more
efficient than other sample DMUs and the efficiency scores of all other DMUs are assigned
accordingly. This has therefore made the estimated efficiency scores relatively subjective. The
DMUs identified as fully efficient are only benchmarks within the sample, making it hard for
cross sample comparisons. In addition, DEA has another major problem, self-identifiers and near-
self-identifiers (Bauer et al., 1998). A bank could be assigned fully efficient not because it is
superior to the other sample DMUs but simply because none of the other DMUs or their linear
combinations is comparable. While for the SFA, its calculated efficiency scores are more
objective and allow the comparison across samples.
Since no consensus view about which method is better than the other has ever been reached in the
academic word, compared the advantages and the limitations of each method and also taking the
need of this research into account, I am planning to adopt the parametric approach, SFA in the
following empirical analysis part.
3.3 Literature Related to X-efficiency Study
Given the importance of the financial sector, numerous studies have been done focusing on
measuring the efficiency of commercial banks across developed countries. This is mainly because
compared with the developing countries, the financial systems in the developed countries tend to
be more mature and their banking systems are also more sophisticated. In addition, due to their
relatively longer history, data of banks in the developed nations are also much easier to get access
to and more reliable. These studies normally adopted both parametric and nonparametric
approaches to measure the overall, technical, allocative, profit and cost efficiency of the banks. In
31
Dissertation Mingyu Xiang
the US, Simper & Drake (2002) adopted input-oriented DEA model to measure the production
efficiency of the US commercial banks during 1984 to 1998. Similarly, many other studies are
also target on the US banking sector, such as Schaeck and Cihak (2008), Allen and Santomero
(2001), and Clark and Siems (2002). In the meantime, there were also many studies focusing on
other developed countries, including Drake (2001) and Webb (2003), Simper and Drake (2003)
for the UK banking industry, Maudos et al., (2002), Kumbhakar et al. (2001), Salas and Saurina
(2003) and Fuentelsaz et al., (2002) for the Spanish banking industry, Girardone et al., (2004) for
the Italian banking industry, Said and Bouri (2013), Weill (2006), Chauveau and Couppey (2000)
for the French banking industry, Kirkwood and Nahm (2006) for the Australia banking industry,
Pasiouras et al., (2008) for the Greece banking industry and Sufian and Majid (2007) for the
Singapore banking industry. In addition, many cross-country researches had also been conducted
to compare the efficiency level of the banking sectors operating in different countries. For
instance, Beccalli et al. (2006) investigated bank efficiencies in five countries, including French,
Germany, Italy, Spain and UK and the study of Liadaki and Gaganis (2008) was based on 15
European countries.
Based on the studies of Loukoianova, E. (2008) and Fu and Heffernan (2007), the average
efficiency scores of the Japanese banks, banks from the European Union (EU), US banks, and
banks from the developed nations were about 69%, between 79%, 91% and 85% respectively. In
general, these studies were focused on following four aspects: the influences of ownership
structure on the efficiency of the banks (Levine, 1996; Weill, 2003; Havrylchyk, 2006; Grigorian
& Manole, 2006; Kraft et al., 2006; Lensink et al., 2008). For instance, they are trying to
investigate whether the private ownership could improve a banks efficiency level; or whether the
foreign banks are more efficient than that of the domestic banks. The second area attracted wide
research interest mainly related to the impacts of financial deregulation on the efficiency of the
banks (Hubbard & Palia, 1995; Lozano-Vivas, 1998; Black & Strahan, 2002; Wright, 2002;
Abbott, 2009; Kerr & Nanda, 2009). The formation of the European Union was expected to
improve economic harmonization across the European region. However, how this would impact
on the financial system and the efficiency of the individual banks? The third research area is
related to the influence of acquisition and mergers (Rhoades, 1996; Berger & Humphrey, 1992; 32
Dissertation Mingyu Xiang
DeYoung, 1997; Panetta & Salleo, 2002; Ashton & Pham, 2007). Whether the efficiency of the
banks could be improved via alliance with a bigger and stronger competitor? Last but not least,
many studies having also been done to compare the different efficiency measures based on data
from different countries (Hasan & Hunter, 1996; Bauer et al., 1997; Eisenbeis et al., 1999; Weill,
2004).
For the first research area, it is expected that privatization would increase the efficiency level of
the banks effectively. This is mainly because by transferring the state-ownership to private
ownership, it may help the banks to improve their corporate governance practice and risk-
management behaviors, pushing them to change the operational mode to become more profit-
oriented and also assisting them to allocate the limited financial resources more effectively.
Among different types of private ownership structure, a special case is the foreign ownership. For
most of the emerging economies, they welcome such foreign investment as it may generate a
series of positive impact to the domestic banking sectors. For example, they may bring in more
advanced technologies, management expertise and may also intensify the competition within the
domestic banking sector. This may in turn to push the local banks to improve their own
operational efficiency to become more competitive (Levine, 1996).
For the empirical studies, Weill (2003), Havrylchyk (2006), Hasan and Marton (2003), Jemric
and Vujcic (2002), Isik and Hassan (2002) all supported the above argument, concluding that
privatisation was indeed an effective way to enhance a bank’s efficiency, in particular among
countries during transition such as Czech Republic, Poland, Hungarian, Croatia and Turkey.
Similar conclusion has also been reached by Fries and Taci (2005) based on their study of 15 East
European transition countries. Compared with the SOBs, the operational efficiency and the cost
efficiency of the private banks are higher (Grigorian & Manole, 2006). On the other hand, when
the foreign banks were included into the sample, it has been found that they tend to be the most
efficient banks within the sample (Bonin et al, 2005). It was followed by the domestic private
banks while the SOBs were among the least efficient ones. The reason was explained by the more
advanced skills, employees and technologies processed by the foreign banks. However, Karas et 33
Dissertation Mingyu Xiang
al. (2008) argued that in Russia, the SOBs were actually more efficient than the private banks and
the foreign banks and similar conclusion have also been reached by Lensink et al. (2008) and
Kraft et al. (2006) in their studies of European transition countries and Croatian. The inferior
performance of the private banks might because of the government’s protection over the state
sector. While for the foreign banks, their difficulties were mainly comes from the inability of
coping local environment. Different cultural background, institutional arrangement and
regulatory system made the foreign banks hard to replicate their success in their home countries.
In addition, when the cost and profit efficiency were considered separately, the results would
become even more complicated. In Yildirim and Philippatos’s (2007) study, they adopted SFA
approach to estimate the bank efficiency of 12 central and Eastern European countries during the
period of 1993 to 2000. Their results showed that although the private banks were more cost
efficient than the SOBs, their profit efficiency was poorer than that of the SBOs. This may again
indicate that due to their relatively small size, the private banks have not got enough power to
compete with the SOBs effectively over the market. Therefore, to improve their own
performance, they tend to focus more on internal costs control rather than expanding income
generation sources.
For the studies base on the banking sector of developed nations, such as the US, UK, France,
Germany and Spain, they generally found that the foreign ownership could not improve the
efficiency of the private banks significantly (DeYong & Nole, 1996; Altunbas & Molyneux,
2001; Borovicka, 2007). The domestic banks were found to have better performance on both cost
efficiency and profit efficiency than the domestic private banks and the foreign banks. This
argument was supported by many researchers such as DeYoung and Nolle (1996), Chang et al.,
(1998), Berger et al., (2000) and Borovicka (2007). In Austria, Otchere and Chan (2003)
concluded that when the Commonwealth Bank of Australia (CBA) tried to privatize the domestic
Australian banks, they received substantial resistance. Therefore, based on the existing studies, it
could be concluded that the overall banking efficiency of the domestic private banks is higher
than that of the SOBs in transitional countries, whereas the same conclusion does not hold for the
developed countries.

In terms of bank efficiency and deregulation, a positive relationship between them had been
concluded in general. They believed that the financial liberalisation would increase the flexibility
in banks’ operation and enhance the efficiency of the financial system. In Jayaratne and Strahan’s
study (1998) of the US banks during the deregulation period of 1970s to 1994, they found that the
lower entry barriers had attracted more private and foreign investors into the banking industry
and hence enhanced the competition, efficiency and effectiveness of credit allocation. The result
also have been proved by Hubbard and Palia (1995), Black and Strahan (2002), Kerr and Nanda
(2009) in their studies. Deregulation has led to a more competitive financial system and
consequently contributes to higher levels of productivity and efficiency (Wright, 2002; Abbott,
2009). However, Humphrey and Pulley (1997) argues that during the post-deregulation period,
the efficiency of the small-size banks may not be improved due to fierce competition. Since 2002,
the establishment of the European Union (EU) has led to financial liberalisation and the
subsequent establishment of a modernized financial institution system among the new EU
members. This has therefore triggered many scholars trying to investigate whether the efficiency
of the banks have also been influenced by such significant policy changes. However, the results
were quite mixed (Lozano-Vivas, 1998; Caus and Girardone, 2004).
For the studies analysing the impact of merger and acquisition (M&As) on banks’ efficiency,
most of them believed the performance of bank will be enhance by M&As. The M&As action
may lead to the deduction of overlapping, allowing wider geographic access, helping the banks to
realize economic of scale and enhancing their risk resistance ability (Rhoades, 1996). During the
period from 1980 to 1994, there was a big wave of merger activities in the US banking industry.
Many studies showed that, the profit efficiency of the U.S. banking sectors had been enhanced by
such M&As due to the risks diversification effect (Berger, 1998; Akhavein, Berger & Humphrey,
1997). In the meantime, their cost efficiencies have not been changed significantly, only up by
5% in average (Berger & Humphrey, 1992; DeYoung 1997; Peristiani, 1997). However, if the
1990s data were employed, the positive impact generated by M&As on cost efficiency would be
greater, as high as 10% (Akhavein et al., 1997). Similar studies have also been conducted in other
35
Dissertation Mingyu Xiang
developed countries and the conclusions were also mixed. Using M&A data of UK banks during
1998 to 2004, the study of Ashton & Pham (2007) demonstrated that after consolidation, the cost
efficiency of the merged banks had experienced significant improvement. They explained the
reason as after M&A, the banks were able to control a bigger market share and hence allowed
them to enjoy a certain degree of monopoly power. In Vander Vennet’s study (1996) of 500
European banks, he concluded that if the merge was conducted between banks with similar sizes
or between domestic bank and foreign banks, the subsequent cost efficiency gain would be much
more significant. Such result was also supported by the studies of Resti (1998), Focarelli, Panetta
and Salleo (2002) in Italian banking industry during the period of 1985-1996 and Haynes &
Thompson’s (1999) study of the UK banks. This might because for the consolidation between
extremely big and small banks, it may take some time for both of the sides to integrate with each
other to archive some efficiency gain in the end.
Recently, some other studies shifted their focus, started to test the consistency of different
efficiency measurement methods (Berger & Mester, 1997; Hasan & Hunter, 1996). In general,
they found that the tested results between the parametric method and the non-parametric methods,
the DEA and SFA methods in particular do share some similarities (Drake & Weyman-Jones;
1996; Resti, 1997). Based on the Italian banking sector, Eisenbeis et al., (1999) found that both of
the DEA and SFA method tend to rank the same observation in the similar order. While on the
other hand, some other studies failed to find evidence to support this argument. Bauer et al.,
(1997) employed four methods to test efficiency of the US banks. They concluded that consistent
results have been provided by parametric approaches. However, the results which measured by
DEA and SFA has significant differences. Similar conclusion has also been found by Ferrier &
Lovell (1990). They concluded that the rank order correlation between the DEA and SFA methods
was quite low, at just about 0.2. Recently, Furthermore, Weill (2004) employed three methods to
investigate the efficiency in banking of 12 European countries. He concluded that a positive
relationship has been identified using the parametric approaches across all sample countries
whereas the results measured by DEA failed to show any significant relationship with any other
parametric approaches.

In recent years, the fast economic development of the emerging economies has attracted wide
attention. This has therefore triggered the researches focusing on those countries. Due to data
limitation, only few researches were focused on China in the early period. Nevertheless, along
with China’s accession to the WTO and the fully opening up of its financial sector in 2006,
research focusing on China surged. In general, efficiency studies in China were concentrated on
three areas, including the influence of ownership reform on banking efficiency (Fries & Taci,
2005; Fu & Heffernan, 2007; Ferri, 2009; Yao & Jiang, 2010) the impact of stock listing on banks
efficiency and lastly (Lin & Zhang, 2009; Yao & Luo, 2010), the influences of foreign entry to
the performance Chinese banking sector (Lin, 2005; Lochel & Pecher, 2008; Shen et al., 2009;
Xiong & Hou, 2009; Berger et al., 2009).
As mentioned in the background chapter, historically, China has only got four SOBs. Their close
relationships with the government has allowed them to enjoy substantial monopoly power but
were also forced to be engaged into various policy lending activities. This has directly resulted in
their low efficiency in operation and decision making. This has also been confirmed by many
previous studies that over centralization were negatively related to bank efficiency. In average,
the efficiency of the Chinese banks was ranged between 41% and 52% during the period of 1985
to 2002 (Fu & Heffernan, 2007). Among the various banking types, efficiency of the SOBs was
the lowest, followed by the CCBs while the JECBs were found of having the highest level of
efficiency level (Bonin et al., 2005). Nevertheless, after a series of ownership reform and
privatisation, the efficiency of Chinese banking sector has been improved significantly over the
past decade. According to the study of Yao & Jiang (2010), the average profit and cost efficiency
of the Chinese banks have been improved to 63% and 74% respectively. Compared with the
JECBs and CCBs, the SOBs were still the least efficiency banks. However, if eliminate the
negative impact of scale efficiency, the actual technical efficiency of the SOBs has actually
surpassed that of the JECBs (Luo and Yao, 2010). This was mainly because of the relative large
size of the SOBs. To get access to the widest range of customers, they have established extensive
networks and employed a large number of employees. This has directly dragged down their
37
Dissertation Mingyu Xiang
overall efficiency level. On the other hand, the superior performance of JECBs might also result
from their geographical location (Ferri, 2009). Instead of spreading their operation across all the
regions, they tend to concentrate more on those prosperous East-coastal provinces. Since the
economic performance of those provinces was far better than the national average, this has
consequently led the JECBs to enjoy a higher than average profit.
In terms of the impact of stock listing on the Chinese commercial banks’ efficiency, since most of
them were only listed on the market since the 2006, the study was quite limited. It was expected
that once the banks were listed on the stock market, they would subject to increased public
supervision and could get access to wider funding opportunities and consequently, their efficiency
could be improved. The early study has been done by Liu and Song’s based on a sample of
JECBs. They concluded that the two listed banks, CMB and PDB were indeed display a higher
than average efficiency level. Later, a study conducted by Lin and Zhang (2009) based on a panel
of Chinese banks over the period of 1997 to 2004 concluded that banks that went through foreign
acquisition or public listing had recorded better pre-event performance. However, soon after the
IPO, the positive impact diminished and this was explained as the “selection effect” Lin and
Zhang (2009). A more recent study had been done by Yao and Luo (2010) is based on a sample of
14 listed Chinese commercial banks. They applied both of the DEA and SAF method and
concluded that the average efficiency of the banks has been improved by 5% after IPO. Similarly,
they also found that over 50% of the sample banks’ efficiency had deteriorated immediately after
the IPO year. Therefore, although it is believed that there should be positive link between stock
listing and bank performance, such conclusion still needs to be interpreted with caution.
Lastly, regarding the influences of foreign entry on the performance of Chinese commercial
banks, it was since the 2001 WTO entry that China has gradually opened its market for foreign
competition. It was until 2006 that the country’s financial market has fully opened for foreign
competition. Many foreign banks entered the market seeking for better business opportunities. In
general, when the foreign banks come to China, they would either acting as a strategic investor,
acquiring a minority stake in the Chinese banks or establishing its own branches (Xu, 2011). As 38
Dissertation Mingyu Xiang
suggested by Berger et al., (2009) that the enrollment of foreign banks on board would help their
Chinese partners to improve their efficiency level, especially for those smaller banks. Garcia-
Herrero and Santabarbara (2008) added that it was more likely for the Chinese banks to achieve
an efficiency gain if their foreign partner was acted as a strategic investor rather than a pure
financial provider. They believed the foreign strategic investor would bring in advanced
technologies for risk control, promoted business diversification and enhanced reputation in local
and global capital markets (Lochel & Pecher, 2008). Similar conclusion has also been reached by
(Ling and Lu, 2004; Lin, 2005; and Liu, 2005). In addition, it has been argued that the increased
foreign penetration would instill addition completion into the Chinese financial market and hence
force the local banks to improve their own operational efficiency (Xiong and Hou, 2009; Zhang
and Wu, 2010). Facing greater competition, the profit margin of the Chinese banks would be
squeezed. Therefore, they were forced to diversify their income sources, and to be more
innovative in product and service design. Nevertheless, despite all these reforms, the big four
SOBs remain dominate the market. Their profit was unlikely to be influenced by the grater
foreign entry (Shen et al., 2009).
Within all these researches focusing on China, few of them compared the efficiency of the
Chinese commercial banks with other foreign banks operating within the same territory. This is
one of the gaps this research aims to fill. In addition, the world financial sector was hit badly by
the recent US financial crisis. How the Chinese commercial banks have been influenced by the
financial crisis is another area left under-researched. In summary, this study aims to investigate
the following research questions:
How the recent financial crisis has impact on the efficiency of the Chinese commercial
banks?
Whether the ownership structure of the banks is still able to influence their efficiency?
Whether the foreign banks could maintain a higher efficiency than the Chinese domestic
banks once they entered into the country?
What is the change of efficiency level of the Chinese banks over recent years? 39

Chapter 4 Methodology and Data
4.1 Methodology
In this study, the parametric approach, SFA is going to be employed. It was developed by Aigner
et al. (1977), Battese and Corra (1977) and Meeusen and Van den Broek (1977) independently
but was proposed simultaneously. The original model could be expressed as the following:
Y j=x j β+v j−u j i=1,2… N
Where x irepresents an input vector for the jth bank; v j denotes the random error and it takes
account of all the measurement error and other random factors that may affect the output variable.
It can be positive and negative so normally it is assumed to follow a normal distribution. For u j, it
represents the inefficiency term and it is assumed to be non-negative, or following the half-
normal distribution. This method is believed to be better than the DEA approach as it
differentiates the random error from the technical inefficiencies.
In the early studies, most of the researches tend to adopt a two-step approach when analysing the
factors that may impact on the efficiency of the banks. They use either DEA or SFA to estimate
the efficiency level of the observations in the first place. Then in the second step, a series of
variables would be chosen to test their influence on the estimated efficiency level. However, such
estimation method suffers a major problem. This is because in the first step, the random errors are
expected to be randomly distributed whereas in the second step, they are assumed to follow
certain functional form. To overcome this problem, Battese and Coelli proposed an extended one-
step model in 1995 and also allowed the use of unbalanced panel data. In this paper, I am also
planning to adopt this method.
To apply the SFA estimation, we need to specify a functional form first. Since the bank is a
financial intermediary with multiple input and outputs, the traditional production function does
not fit for the purpose. Therefore, we decided to choose the Translog function form. Assuming
40
Dissertation Mingyu Xiang
that the total costs of bank j in year t equals to TCjt and it could be expressed as the following:
TC j= f (Y r , j , Pi , j )+ϑ jt+μ jt
If replace the above equation with the Translog function form, it could be changed into:
lnC j=α 0+∑rj
βr ln yrj+∑ij
β i ln c ij+12∑i
∑k
βik ln y ij ln ykj+12∑i
∑z
β iz ln c ij ln czj+∑r∑
iβ i ln yr ln c i+ϑ jt+μ jt
Where Y r , j represents the r-th output of bank j and Pi , jrepresents the price of i-th input. The error
term is comprised with the random error ϑ jt and the technical and allocative inefficiencies μ jt.
Following other literatures, we also impose the homogeneity restrictions (Yao et al., 2007):
∑r
βr=1 ,∑i , z
βiz=0 ,∑i
β i=0
Then the bank specific efficiency scores could then be estimated as expE [−μ|ε ] . It takes the value
between 0 and 1. The higher score, the more efficient the bank is. If an observation has achieved
1, it means that it is fully efficient.
4.2 Data and Variables
In terms of the variables chosen for the test, it could be summarised into two groups, the input
and output variables. However, the classification criteria of the chosen of variables, no consensus
has been reached. This is mainly because of the nature of the bank’s operations. Unlike
manufacturing firms which use raw materials for the production of finished goods, the operation
of the banks is more complicated. The banks are more like a financial intermediately, channeling
funds from the depositors to the borrowers. Therefore, there is no definite input or output of the
banks. For example, for deposit, it could be classified as an output because the banks need to
incur substantial costs, such as human capital and fixed assets to collect the deposit from the
customers. However, on the other hand, it could also be regarded as an input because without
deposit, the banks would have no financial resources to lend out as loans. Consequently, in the
previous studies, two approaches, the production approach and the intermediation approach were
41
Dissertation Mingyu Xiang
commonly employed to define the banks’ input and output variables.
Regarding the production approach, it treats the banks the same as a manufacturing firm, using
labour and capital to produce finished products. The key objective of the banks is profit
maximization. Under such assumption, the inputs of the banks could hence be restricted to the
cost of human capital and capital expenses. While for the outputs, it could be defined as the
number transactions carried out, the new accounts opened or the documents issued within certain
period (Luo and Yao, 2010). On the other hand, the intermediation approach focuses on the
financial intermediary function played by the banks. Although the banks would incur substantial
costs in collecting the deposits, the primary function of the deposits is to be used for lending and
other investments. Therefore, under the assumption of the intermediately approach, apart from
the costs of human capital and assets, the deposit could also be classified as an input variable. On
the other hand, for the output variables, they may include the amount of loans, other earning
assets, or the new profits generated by the banks within certain period. In practice, since neither
of these two approaches could reflect the full picture of the banks operation, they have been used
as complementary to each other. In this research, when determining the input and output
variables, I will use the intermediary approach.
For the data used in this study, they were mainly subtracted from Bankscope. In addition, the
annual statement of the individual banks, the China Statistical Yearbook and the official website
of China Banking Regulatory Committee (CBRC) were also used as supplementary. In total, data
of 39 banks were employed. It includes four SOBs, twelve JECBs, 15 CCBs and eight foreign
banks. The total observation of the sample is 277, covering the period of 2005 to 2012. Due to
data limitation, the data is comprised with an unbalance panel with the smallest 24 banks being
included in 2005 and the largest number of 39 banks being included during 2009 to 2011, as
shown in Table 13 below. For the variables, two price variables were calculated, they are the
interest expense to total deposits and the non-interest expense divided by total assets while the
amount of loans and total earning assets generated were treated as the output variables. To
eliminate the influence of inflation, all these variables are divided by the related GDP Deflator for 42
Dissertation Mingyu Xiang
each year. Another variable, the number of employees was originally chosen as an input variable
as well. However, since for all the eight foreign banks, they did not disclose this information in
the Bankscope, I therefore dropped this variable due to inaccessibility. Table 14 summarises the
correlation coefficient of the input and output variables. It is clear that two output variables are
correlated closely with the input variables, suggesting that the change of input variables would
influence the output level significantly.
Table 13 Number of Banks in Each Year
Table 14 Correlation Coefficient of the Input and Output Variables
In addition to the input and output variables, I have also included a series of explanatory variables
to investigate the factors that may impact on the efficiency of the banks. The first one is the
43
Dissertation Mingyu Xiang
ownership structure. It is measured by a dummy variable. It takes the value of 1 in turn for state-
ownership, joint ownership, city commercial banks and the foreign banks. The second variable is
the return on average assets employed, or ROA. This ratio is a commonly used ratio measuring a
company’s profitability. A higher ratio means that the company could generate more profits with
the assets under control. Hence, banks with a higher ROA ratio are expected to be more efficient
as they could use the resources more efficiently. The third ratio is equity to assets ratio (E/A) and
it could be regarded as a measurement of a company’s exposure to financial risks. A higher E/A
ratio indicate that within the banks’ asset portfolio, the equity finance accounts for a bigger
percentage and the hence made the banks less likely to suffer a financial distress. Moreover, the
E/A ratio could also be interpreted with the budget constraint theory (Luo and Yao, 2010). If the
bank has a higher E/A ratio, it suggests that it may subject to a harder budget constraint. This is
mainly because that due to the residual claim nature of the equity ownership, the shareholders
tend to be more risk averse, prudent and accountable than the debt holders. A lager proportion of
equity finance means that the operation of the banks might be subject to tighter control and
supervision. In addition, the ratio, loan loss reserve to total loans, or LLR/TLs is also expected to
be included for analysis. It measures the credit risks faced by the banks. A higher ratio means that
the bank is more likely to suffer a loss due to the default of the customers. Therefore, a negative
relationship between the LLR/TL ratio and efficiency level of the bank is expected. On the other
hand, this ratio could also be regarded as a proxy for the bank’s risk appetite. If the bank is
willing to take higher risk, it is not surprise that it would have a higher than average LLR/TL
ratio. In theory, a higher risk tends to be related with higher profits. It is thereby hard to say
whether a higher LLR/TL ratio would lead to a higher or a lower level of efficiency. Moreover,
the ratio of loan to deposit, L/D is also used. It measures how much loans have been lent out by
the banks as a percentage of the total deposit collected. A higher level may indicate that the
operation of the bank is highly risky as a shortage of deposits fund may put the bank into
liquidity difficulties. While on the other hand, banks’ lending is expected to generate higher
return for them, so a high ratio may also indicate that the bank uses its funds more effectively. For
each of these variables, they may influence the efficiency of the banks in different ways and the
Table 15 and Table 16 below present the summary statistic and the correlation coefficient matrix
of the variables used for the SFA test. None of the independent variables used for the test is
highly correlated. This ensures that the tested result is not biased. 44

Chapter 5 Results of the Empirical Analysis
To test the efficiency level of the chosen banks, the computer software, Frontier 4.1 used and the
result is summarises in Table 17. The average efficiency score of the sample banks is 0.71, in line
with the previous studies. In terms of the six explanatory variables, four of them were found of
being able to influence the efficiency level of the banks significantly.

Notes: *** means that the variable is significant at 1% level; ** means that the variable is significant at 5% level and * means that
the variable is significant at 10% level; ROA, return on asset; LLR/TL, loan loss reserve to total loans; E/A, equity to assets.
It is quite surprised to find that ROA influences the efficiency level of the banks negatively.
Theoretically, highly profitable banks tend to have a higher efficiency as the resources have been
used more efficiently. The negative relationship between ROA and bank efficiency could be
explained by China specific reasons. In China, despite all the reforms, the banking system
remains dominated by the SOBs. The central bank has also set up strict requirements about the
minimum lending rate and the highest deposit, effectively ruling out market competitions.
Consequently, with extensive network distributed across the country and the monopoly power
over the market, the four SOBs could generate extremely high profit although their operational
efficiency is lower than other types of banks. The second variable, E/A has been found of having
positive relationship with the bank efficiency. This is in line with expectations. Banks with a
tighter budget control tend to have a higher efficiency as they need to convince the shareholders
that the resources have been used effectively. For the variable, Loan / deposit ratio, it has been
found of having a negative relationship with the bank’s efficiency level. This may indicate that
banks which are less risk averse tend to have a lower efficiency and it could be linked with
China’s specific situation directly. The financial market in China is quite immature and there is no
established credit rating system. Therefore, for the banks’ lending a relatively bigger percentage
of their deposits, there is also a higher possibility that these lending may go bad. This explains
why banks with a higher Loan/deposit ratio tend to have a lower efficiency level. Lastly, the
variable, IPO has also been found of having a positive relationship with the banks’ efficiency but
it is only significant at the 5% level. Such result proved the effectiveness of the strategy adopted
by the Chinese government to reform its SOBs. After the banks having been listed on the stock
exchanges, their operations would subject to increased public scrutiny and hence giving them
more pressure to enhance their efficiency.
46
Dissertation Mingyu Xiang
On the other hand, two variables, the GDP growth rate and the ownership structure are found of
unable to influence the efficiency level of the banks significantly. This might because of the
sample period employed in this study. It ranged from 2005 to 2012 during which the economic
development in China has been maintained at a relatively stable rate. Without substantial
expansion, business opportunities provided to the banks are also limited and therefore the model
failed to detect a statistically significant relationship between GDP growth and banks’ efficiency
level. The insignificant relationship found between bank ownership structure and efficiency level
is in contrast to many of the previous studies. This is again could be explained by the unique
sample period employed in this study. Since 2006, the four SOBs were listed on the stock
exchanges successfully. In the past, the state ownership is expected to influence the efficiency of
the banks negatively. However, once they have been listed and become shareholding
corporations, they are also expected to be transferred into real commercial banks with profit
maximization being set as the ultimate target. Consequently, the influence of the bank ownership
is diminished. For the foreign banks, although they are expected to have a higher level of
efficiency compared with the domestic banks, the different culture and institutional background
in China may impede their display of full potential. As a result, in China nowadays, ownership
structure is found of having no significant impact on the efficiency of the banks.
In terms of the efficiency of the banks, in average, the efficiency level of all 277 observations is
0.71 and the average efficiency level of the SOBs, JECBs, CCBs and FBs are 0.72, 0.78, 0.74 and
0.73 respectively during the sample period. Although the JECBs seem to be the most efficient
type of bank within the sample, it does not different significantly with the rest three banking
types. This is consistent with the previous statistical analysis. The highest efficiency score is
achieved by a foreign bank, BNP in 2005 at 0.99 while the lowest efficiency score among the
sample banks has been achieved by a city commercial bank, Xiamen Bank in 2012 at just about
0.34. The average efficiency level of all banks over 2005 to 2012 is decreasing gradually from
0.82 to 0.67. This could be explained by the unfavorable economic environment in China, the
unstable financial system triggered by the US financial crisis and the broken out of European debt
47
Dissertation Mingyu Xiang
crisis over the past few years. In 2005, the average efficiency level of the sample banks is 0.82
and it was further improved to 0.82 in 2006. This might because that it was in 2006 that most of
the SOBs obtained stock listing and they were pushed to present better than normal performance
before listing. However, once listed on the market successfully and accompanied by the worsened
international environment, performance of the banks deteriorated.
Figure 4 and Table 18 present the average efficiency score of different banking types over 2005 to
2012. For the SOBs, although their efficiency score was lower than the sample average during
2005 to 2009, they managed to surpass the average efficiency level in 2010. It is worth noting
that actually since 2010, decouple from the general downward trend, the average efficiency levels
of the SOBs have increased steadily from 0.72 to 0.75. This may indicate that first of all, the past
reforms implemented by the Chinese government focusing on the SOBs were proved to be
successful, helping them to become more and more efficient over years. On the other hand, it also
suggests that operations of the SOBs were less affected by the worsened external environment.
Due to their big size and the dominate position over the Chinese financial system, a slowing
down economy would not dampen their profit significantly. In addition, their prudent nature also
determined that they had only got limited exposure of the US securities. This might be another
reason that explains why they could achieve a steadily growth while the rest of the sector was
undergoing a difficult time. For the JECBs, at 2005, their average efficiency score is the highest
among all types of banks at about 0.81 but it fluctuates up and down during the sample period. In
2011, their average efficiency was even surpassed by the SOBs and this may directly result from
the slowdown of the Chinese economy over the past two years. Unlike the SOBs which have an
extensive network and a close relationship with the big enterprises, operations of the JECBs are
more closely related to the local smaller businesses. Consequently, a drop in economic growth
may damage the income sources of the JECBs and hence making them less efficient in general. In
addition, the decline in efficiency of the JECBs may also because of the increased competition.
The fast growth of the CCBs and foreign banks could hardly violate the market position of the
SOBs, but could pose direct pressure to the JECBs. To compete with other types of banks, the
JECBs may incur addition costs in recruiting highly skilled employees and purchasing advanced
technologies and this might be the reason contributing to the declined efficiency of the JECBs. 48
Dissertation Mingyu Xiang
For the foreign banks, at beginning, they are the most efficient banks in China with an average
efficiency score of 0.92 in 2005. However, the broken out of the US financial crisis has made
their efficiency declined continuously to become the least efficient banking type in 2011.
Nevertheless, in 2012, their efficiency level started to recover rapidly. With sophisticated
technology, advanced management expertise, matured management system and less regulatory
constraints, it is expected that these foreign banks would impasse substantial pressure to the
Chinese domestic banks in the near future.

Starting from the late 1970s, China has also initiated a series of reforms trying to transform its
mono-banking system to a decentralised, market oriented and competitive system. The reforms
implemented by the Chinese government included the introduction of a three tier banking system,
the diversification of the ownership structure of the banks, the listing of commercial banks onto
the stock exchanges and the gradual opening up of domestic financial sector for foreign
competition. Up to the end of 2010, 17 Chinese commercial banks have been listed on the stock
exchanged successfully. They include four SOBs, 10 joint equity commercial banks and three city
commercial banks. Over the past five years, influenced by the US financial crisis, many world
baking giants have experienced serious financial difficulties. Their shares have plummeted and
some of them have even been transformed into state-ownership. However, the Chinese
commercial banks seemed decoupling from the rest of the world, managing to achieve superior
performances consistently.
After all these reforms, China can be said of in processing of one of the biggest banking sectors
in the world. By the end of 2012, among the world’s biggest 10 banks measured by market
capitalization, China accounts for four of them. In particular for the Industrial and Commercial
Bank of China (ICBC), it also has the largest customer base, number of employees and deposit
stocks. In addition, Chinese banking sector has also reported high growth in its profitability in
recent years. In 2010 and 2011, total profits were up by 34.5% and 14.6% respectively year-on-
year (Xinhua, 2012). For the ICBC alone, its recorded net profit in 2011 was 208.4 billion yuan,
up by 25.6% from a year earlier, ranking the highest among all the banks across the world.
However, facing an unfavourable international financial environment in general and a slowdown
of Chinese economy in particular, how these banks could maintain such rapid increase in profit
would be a real challenge. With increased foreign entry, the operational environment of the
domestic banks would become even more complicated. With more experiences and advanced
technology and management expertise, it is no doubt they would impose additional pressures to
the Chinese commercial banks. Therefore, in this paper, five questions were investigated with the
data of 39 banks during the period of 2005 to 2012. In particular, I am trying to find out the 50
Dissertation Mingyu Xiang
change of efficiency of the Chinese commercial banks over recent years; how their efficiency has
been influenced by their ownership structure, their stock listing status, their attitude towards risks
and recent US financial crisis. In addition, the performance of the foreign banks in China will
also be addressed.
For the previous studies on the Chinese banking sector, normally they concluded that the
efficiency of the Chinese commercial have been improved continuously over the past decades.
Among the different banking types, the state-owned banks were the least efficient group. Their
close relationship with the government has led to substantial policy oriented lending and
consequently accumulated large amount of non-perforating loans. For the JECBs, since they tend
to adopt a mixed ownership structure and concentrate their operations in the economic developed
regions, their performance are normally higher than other types of banks in China. Regarding
increased foreign entry, they general concluded that they have brought in increased competition
to the Chinese banking sector. To compete with their foreign counterparts, many Chinese
commercial banks were forced to reduce their interest margin and incur additional costs in staff
recruitment, new product and service design and purchasing of advanced technologies. However,
it has also been said that due to different culture background and the tight government control, it
is hard for the foreign banks to replicate their success story in China as their home country.
Therefore, in this paper, 8 foreign banks were also included in the study. I am trying to track their
change of efficiency once they come into the China.
This study employed the parametric method SFA for the analysis. The data are mainly subtracted
from Bankscope. In addition, the annual statement of the individual banks, the China Statistical
Yearbook and the official website of China Banking Regulatory Committee (CBRC) were also
used for cross-checking. In total, data of 39 banks were employed. It includes four SOBs, twelve
JECBs, 15 CCBs and eight foreign banks. The total observation of the sample is 277, covering
the period of 2005 to 2012. For the variables, the input variables include two price variables, the
interest expense to total deposits and the non-interest expense divided by total assets while the
amount of loans and total earning assets generated are chosen as the output variables. To 51
Dissertation Mingyu Xiang
eliminate the influence of inflation, all these variables are divided by the related GDP Deflator for
each of the separate years. In addition, six explanatory variables are also included to test their
influence to the efficiency of the banks. They are the ownership structure of the banks, the stock
listing status of the banks, ROA, Loan to deposit ratio, Equity to assets ratio and the GDP growth
rate.
In general, we found that among the six independent variables, four of them could influence the
efficiency of the banks significantly. It is quite surprised to find that ROA influences the
efficiency level of the banks negatively and this might because of the dominate position of the
four SOBs in the Chinese banking industry. The second variable, E/A has been found of having
positive relationship with the bank efficiency and it is in line with expectations. Banks with a
tighter budget control tend to have a higher efficiency as they need to convince the shareholders
that the resources have been used effectively. For the variable, Loan / deposit ratio, it has been
found of having a negative relationship with the bank’s efficiency level. This may indicate that
banks which are less risk averse tend to have a lower efficiency. Lastly, the variable, IPO has also
been found of having a positive relationship with the banks’ efficiency. This proved the
effectiveness of the strategy adopted by the Chinese government to reform its SOBs. After the
banks having been listed on the stock exchanges, their operations would subject to increased
public scrutiny and hence giving them more pressure to enhance their efficiency. On the other
hand, two variables, the GDP growth rate and the ownership structure are found of unable to
influence the efficiency level of the banks significantly. This might because of the sample period
employed in this study. It ranged from 2005 to 2012 during which the economic development in
China has been maintained at a relatively stable rate. Without substantial expansion, business
opportunities provided to the banks are also limited and therefore the model failed to detect a
statistically significant relationship between GDP growth and banks’ efficiency level. Regarding
ownership, since most of the reforms were finished by 2005 and the SOBs were listed on the
stock exchange and being transformed into shareholding corporations, the influence of the bank
ownership has therefore diminished. For the foreign banks, although they are expected to have a
higher level of efficiency compared with the domestic banks, the different culture and
institutional background in China may impede their display of full potential. As a result, in China
nowadays, ownership structure is found of having no significant impact on the efficiency of the
52

banks.
In terms of the efficiency of the banks, in average, the efficiency level of all 277 observations is
0.71 and the average efficiency level is deteriorated year-after-year. This could be explained by
the unfavorable economic environment in China, the unstable financial system triggered by the
US financial crisis and the broken out of European debt crisis over the past few years. For the
SOBs, although their efficiency score was lower than the sample average during 2005 to 2009,
they managed to surpass the average efficiency level in 2010 and become the most efficient
banking type in 2012. This may indicate that the past reforms implemented by the Chinese
government focusing on the SOBs were proved to be successful, and it also suggests that
operations of the SOBs were less affected by the worsened external environment due to their
bigger size and monopoly power over the market. For the JECBs, at 2005, their average
efficiency score is the highest among all types of banks at about 0.81 but it fluctuates up and
down during the sample period. This may because the operations of the JECBs are more closely
related to the local smaller businesses and are more likely to be influenced by the increased
market competition. Therefore, for the JECSB, they need to develop new income sources to
improve their existing operations to maintain competitive in the market. For the foreign banks, at
beginning, they are the most efficient banks in China with an average efficiency score of 0.92 in
2005. However, the broken out of the US financial crisis has made their efficiency declined
continuously to become the least efficient banking type in 2011. Nevertheless, it is believed that
with once the economic condition recovered, these banks would growth up quickly and impose
substantial pressure to the local banks in the near future.
Lastly, in terms of the limitation of this research, first of all is the choice of variables. If data
related to the salary payment to the employees and the number of employees could be found,
another price variable could therefore be calculated and used in the analysis. Secondly, it is the
relatively small size of the sample. If time allowed, more data about different types of banks
could be collected so as to reach a more solid conclusion.
