ACKNOWLEDGEMENTS
This dissertation was completed under the help of many individuals.
First of all, I am in debt to my supervisor, Professor Lawrence Wai-
chung Lai. Without his inspiration, patient guidance, and invaluable
advice, both intellectually and spiritually, this dissertation could hardly be
in reality. So I would like to express my sincere gratitude to him here.
Secondly, I am also indebted to Miss Lin Yuet-yim Veronica, who
gave me advice and assistance whenever I encounter problems in my
dissertation. I would like to wish her every success in her postgraduate
studies.
In addition, I would like to thank Mr. Thomas Chor-hung Wan for
his assistance and Mr. Ian Ping Yung because a portion of the Green Belt
zones data up to the year 2003 used in this dissertation was collected by
him in his research. Besides, I would like to take this opportunity to show
my appreciation to my family and friends, especially Brother Thomas
Favier, the former principal of St. Joseph’s College and other teachers,
my fellow studio groupmates (Sing, Dick, Yeung, Eddie and Walter),
classmates (Emily, Holly, Wai, Lokman, Wave and other Italians),
vii
Zodiacians (Regis, Jason, Joseph, Darwin) and other good friends
(Kenneth, Candy, Kitty, Cindy) for their generous support.
Last but not least, Special thanks have to be granted to my parents,
my grandparents and my younger brother for their enduring
encouragement. Thanks Cecilia Leung for giving me the incentive to
work independently, and teaching me an invaluable lesson since
31/3/2003 in Stanley (El Amor en los Tiempos del Colera). Above all, I
have to express my greatest thanksgivings to God as everything I possess
is granted by Him. Finally, may God bless all the LaSallian brothers,
Jesuit fathers and other priests, who spend their whole lives to serve God.

ABSTRACT
As a first focused attempt to apply Lai and Ho’s ideas (2002), this
dissertation investigates seven refutable hypotheses in relation to
applications for uses under green belt zoning in Hong Kong’s new towns.
There is an express presumption of ‘against development’ and ‘limited
development’ policy for green belt zones and this dissertation tests
whether the Town Planning Board (TPB) actually follows this policy
when granting planning approvals in Hong Kong’s new towns. Attention
will be paid also on planning applications with respect to residential uses.
Non-aggregated planning application statistics for Green Belt zones in
Hong Kong from 1 January 1975 to 31 August 2004 are used for
evaluating the hypotheses which are related to different material
considerations made by the Town Planning Board such as locations (new
towns versus other broad regions, urbanized new towns versus more rural
new towns), scale of proposed development (any presumption of limited
development versus the rent-seeking argument) and types of use
(ordinary residential versus Village Typed House) in Green Belt zones
situated in Hong Kong’s new towns at the time of decision-making. It is
found that the decisions made by the TPB were not random in the sense
that it did look into specific factors for systematic observations of success
or failure for applications in respect of Green Belt zones in Hong Kong’s
x
new towns. Results showed that location, scale of development and types
of use are statistically speaking significant factors shaping the decisions
of the TPB when vetting planning applications.

CHAPTER 1
INTRODUCTION
Town Planning in Hong Kong’s New Town1
The Hong Kong government introduced the new town program in
the 1970s with the objectives to alleviate the urban congestion, residing
the overcrowding population and provide substantial housing units.
Urban development pace in Hong Kong has been very rapid. In spite of
the growing of population in the urban areas of Hong Kong and Kowloon,
there are major growths taking place in the new towns in the New
Territories. The New Town Development Program in Hong Kong that
sought to accommodate more than three million people, which is the
largest new town program in the world achieved by massive public
investment. The development of new towns played a very important role
in Hong Kong’s development history.
1. New towns can be defined as “planned communities consciously created in response to clearly stated objectives” (Galantay 1975, p.1). The concept of new towns originated from the idea of Ebenezer Howard, the Garden Cities of Tomorrow (1898). He proposed the idea of self-contained new towns. The Garden City combines the advantages of intensive urban life with the beauty and pleasures of the country.
The idea of developing new towns in the New Territories was mooted by Sir
Patrick Abercrombie (Lai 1999a) during his visit to Hong Kong in 1949 but it was not until the early 1970s that this ambitious program of developing new towns became a reality. In fact, every modern new town is designed in similar to the idea of Howard (1898).
2
There are now nine new towns in Hong Kong which can be
classified into 3 generations. First generation new towns, Sha Tin, Tsuen
Wan and Tuen Mun, are founded earliest and are almost completed.
Second generation new towns, Tai Po, Fanling/Sheung Shui and Yuen
Long, are in the advanced development stage. Third generation new
towns, Tseung Kwan O/Sai Kung, Tin Shui Wai and Tung Chung, are
still in the active development stage. They fall within theoretically
restricted definition of independent, self-contained and balanced
settlement (Bristow 1989). Since the new towns in Hong Kong are
growing larger and accommodating an increasing number of people, it is
expected that an increasing emphasis of concern would be put on the new
towns and the study of new town zoning in Hong Kong would be fruitful.
One of the most famous works about Hong Kong’s new towns was
written by Roger Bristow (1989). He examined the overall
conceptualization of the new-town program at length and undertook
detailed analysis of individual towns and of specific topics illustratively.
However, quantitative analysis of planning application statistics for new
towns in Hong Kong has not been given sufficient interest of research in
the past by researchers. Therefore, this dissertation will quantitatively
analyze the planning application statistics.

Background of this Study
In the United Kingdom, it is accepted in principle and in law that
there is no private right to develop land unless it is publicly acceptable by
a political decision (Cullingworth and Nadin 2002, p. 129; Dobry et al
1996, p.3). In contrast to the U.K., there is no such general presumption,
as pointed out by Cullingworth and Nadin (2002) and Dobry et al (1996)
in planning control against development in Hong Kong. But Hong Kong
does have a ‘presumption against development’ in the Green Belt (GB)
zones and a number of other zones. Green Belt zones act as buffers for
urban concentrations. It is the “physical separation of town and country
by a building free zone, usually encircling the town” (Home 1997, p.14).
The planning intention2 of Green Belts is primarily for defining the limits
of urban and suburban development areas by natural features and to
contain urban sprawl as well as to provide passive recreational outlets.
There is an express presumption of ‘against development’ and ‘limited
development’ policy for green belt zones unless there is a strong planning
ground may an application for development of a limited scale is permitted
(Lai and Fong 2000, p. 127; Lai and Ho 2001d, p.325).
2. The planning intention of zones in Hong Kong could be found in the
Explanatory notes in any OZP.
4
Green Belt zoning is not restricted only to rural areas. Planning
applications in urban areas are common (Lai and Fong 2000). According
to the planning application statistics by Lai and Fong (2000), there are
totally 770 section 16 applications during years 1975 to 1998, which is
not a small number. Moreover, most applications within the Green Belt
zones were found in the New Territories. In the Green Belt zoning, there
are successful cases with respect to Village Type House applications
(small house or New Territories Exempted House) and ordinary
Residential applications.
A discrete choice model, the probit model, would be used here to
evaluate and present planning application data for the Green Belt zones in
Hong Kong from the year 1975 to 2004. For material considerations in
planning applications, the studies by Lai and Ho (2001a, d) has initiated
the factors of success for planning applications within Green Belt zones.
The zoning and planning criteria of the Hong Kong’s new towns
with respect to Green Belt (GB) zone will be investigated in this
dissertation. This dissertation is to continue the studies of Lai and Ho
(2001a, d) and Yung (2004) on Green Belt zones to investigate further the
material considerations (location factor, scale of development, and the
use under application) of the TPB in granting planning approvals for
5
applications in Green Belt zone and test whether the Town Planning
Board (TPB) follows the “presumption against development” and
“limited development” policy when granting planning approvals in Hong
Kong’s new towns.

CHAPTER 2
LITERATURE REVIEW
The Study of Development Control
Development control is an interesting area of research. It is an
integral component of urban land use policy and has attracted
considerable scholarly research (Lai 1994, 1996, 1997a, 1997b, 1998a,
1998b; Tang and Tang 1999; Lai and Ho 2000, 2001a, b, 2002b, 2003;
Chau and Lai 2004). It is the process by which the proposals in a
development plan are put into practice accordingly by either public or
private agencies (Keeble 1969). Lai (1997a) explained that, in terms of
economic theory, the development control mechanism as a regulatory
system is a means of non-price allocation of development and
redevelopment rights.
Underwood (1981, p. 194) generalized and divided the issues of
development control into two types: policy issues and action issues.
Policy issues, the main concern of this dissertation, could be further sub-
divided into “roles of plans” and “material considerations”. The “role of
plans” concerns about the extent of the planning policies that are adhered
to and implemented through development control (Underwood 1981).
There is much research on this area (Whitehead 1989; Tewdwr-Jones
7
1993; Tang and Tang 1999; Tang and Choy 2000; Lai and Ho 2000,
2001a, b, 2002b, 2003; Chau and Lai 2004). The “material
considerations” is exactly what the term suggests: considerations that are
material to the taking of a development control decision (Cullingworth
and Nadin 2002, p.129). In other words, factors for success in planning
applications are just the material considerations of planning authority
(Underwood 1981; Tewdwr-Jones 1993; Willis 1995a; Tang and Choy
2000; Tang et al. 2000; Lai and Ho 2000, 2001a, b, 2002b, 2003; Chau
and Lai 2004).
The Use of Development Control Statistics in Land Use Planning
Research
It is possible to evaluate the assertions of the economic critics of
development control with the availability of planning application
statistics (Lai and Fong 2000). As pointed out by Lai and Ho (2001a;
2001b), the collection and qualitative analysis of development control
statistics would facilitate the econometric analysis of three types of
planning research including hedonic price analysis, verification of
economic theories concerning various dimensions of the behaviour of
planning authorities, and the evaluation of the behaviour of players in the
land market. However, prior to the work of Willis (1995a, b), empirical
research of urban planning was largely confined to hedonic pricing
8
analysis (Fisher and Peterson 1987; Lai and Ho 2001a, 2002a). Most
previous evaluations of the performance of the planning and development
control authorities were either by qualitative analysis or by case studies.
Development control and planning applications statistics (quantitative
approach) were seldom used (Lai and Ho 2001d).
“The current state of art of urban planning research is the debate on
the usefulness and limitations of aggregate planning data, notably the
average success rates of development applications as measures of
development pressures” (Lai and Ho 2002a, p. 128). Carlos (1979)
defined aggregated and non-aggregated data. If each observation in the
data consists of a value of the attribute vector (representing an individual
who has been interviewed), and an observed choice, they are
disaggregated. If the data include only information on groups of people,
they are aggregated or grouped.
In fact, the use of development control data is very popular in
many research areas. The final report of Dobry (1975), which is a review
of development control system, analyzed qualitatively UK planning
statistics. Dobry (1975) argued that the planning mechanism causes
delays. Dobry (1975) argued that the planning mechanism causes delays.
In Hong Kong, scholars and practitioners have criticized the existing
9
planning permission system for being too slow and incurring huge delay
costs. The delay is a pure economic loss that only benefits the
professionals and lobbyists involved (Lai 1997b). Staley (1994), Chau et
al (1996), and Lai (1997a, b) further elaborated on the concept of delay.
Moreover, the studies of Brotherton (1992a, b) for England and Wales,
the work of Lai and Fong (2000) for Hong Kong were also based on the
qualitative analysis of development control statistics. In addition, there
are also a number of researches being done in using this methodology
(McNamara and Healey 1984; Preece 1990; Sellgren 1990; Brotherton
1992a, b; Willis 1995a; Gilg & Kelly 1996).
The use of non-aggregated data or disaggregated data was not
common in planning research compared with the use of aggregated data.
However, as aggregated development control data have many inherent
limitations (Brotherton 1982, 1992a, b; McNamara and Healey 1984;
Buller and Hoggart, 1986; Larkham, 1986, 1988, 1990a; Preece 1990;
Sellgren 1990; Bingham 2001; Lai and Ho 2001d), we need
disaggregated data to make reliable analysis.
There are two econometric models, probit and logit model, that can
conveniently be used to overcome the limitations and controversies of
using aggregate development control statistics (Lai and Ho 2001a). In this
10
dissertation, following the footsteps of Lai and Ho (2000, 2001a, b,
2002b, 2003), non-aggregated data would be employed for analysis.
The Use of Probit Model in Modern Planning Studies3
The first limited dependent variable model was proposed by Tobin
(1958). This is known as Tobit analysis. Lee and Trost (1978) introduced
the use of probit model to study the housing expenditure model of
homebuyers and renters. The model takes into account the simultaneous
determination of how much to spend and whether or not to own or rent.
Following Lee and Trost (1978), a lot of studies have been conducted by
using the probit model in the housing aspects (Goodman 1988; Horioka
1988; Potepan 1989).
In Hong Kong, some researchers (Tang and Tang 1999; Tang and
Choy 2000; Tang et al 2000) used the econometric logit model, which
had been adopted by Willis (1995a), to evaluate the Hong Kong planning
application data in relation to one single permissible use in Residential (A)
zones for a small numbers of observations (242 and 162 respectively)
from year 1987 to 1997.
3. See Lai and Ho (2000).
11
Another binary dependent variable model, the probit model, was
used by Lai and Ho (2000; 2001a, b, c, d; 2002a, b, c; 2003), Chau and
Lai (2004) and Lai and Chan (2004) in evaluating development control
data. They investigated the planning decision criteria of the TPB for
planning applications4. In their studies, they investigated two important
criteria: Analyzing the material considerations of the TPB when granting
planning approvals. Examples are (a) analysis of alleged “rent-seeking”
activities of the planning authorities or analyzing the sensitivity of the
decisions of the planning authorities to exogenous policies, (b) analysis of
the actual separation of two classes of zones with identical uses (Lai and
Ho 2002b; Yung 2004). The significance of using the probit model,
which yields empirical estimates of individual explanatory variables, is
that it would allow us to identify the material considerations, measuring
implementation of land use policies, thus predicting whether a planning
application for a use would be approved by the TPB or whether the
impact of exogenous government policy is binding (Lai and Ho 2001a;
Yung 2004).
4. These are the different material considerations made by the Town Planning
Board such as locations, scale of proposed development, types of use, etc.
12
CHAPTER 3
HYPOTHESES
Empirical Hypotheses relating to the Green Belt Zones
Seven refutable hypotheses relating to the location factor, scale of
development, and the use under application are developed as follows:
Hypothesis I: The probabilities of getting planning permissions for all
uses in GB zones would be the same for applications made
in all broad regions (namely HK, KLN, ISLAND, NT and
RURAL).
Hypothesis II: Planning applications for all uses in GB zones in more
urban broad regions are not associated with greater chance
of being approved than those in rural broad regions.
Hypothesis III: The probabilities of getting planning permissions for all
uses in GB zones would be the same for applications
made in all generations of new towns (i.e. first, second
and third generation new towns).
13
Hypothesis IV: Planning applications for all uses in GB zones in more
urbanized new towns (i.e. first generation new towns and
second generation new towns) are not associated with
greater chance of being approved than more rural new
towns (the third generation new towns).
Hypothesis V: planning decisions in respect of all uses in GB zones do
not show any preference on larger developments
(measured in terms of proposed gross floor area of the
building or use) in the Hong Kong’s New Towns.
Hypothesis VI: Planning applications for the development of Village
Type House in new towns’ GB zones are not associated
with greater chance of being approved than ordinary
residential uses developments in the Hong Kong’s New
Towns.
Hypothesis VII: Planning applications for the development of Ordinary
Residential Developments GB zones are not associated
with greater chance of being approved than Other Uses
like open storage, car park, religious institutions, etc. in
the Hong Kong’s New Towns.
14
Interpretation of Hypotheses
Hypotheses I and II is to test whether location (degree of
urbanization) is one of the decisive criteria for the TPB in approving
planning application. These 2 hypotheses would be tested by the first data
pool (with 1,275 data sets). Hong Kong is geographically divided into
five regions: Hong Kong Island, Kowloon, and New Territories which
could be further subdivided into urban New Towns, Rural Areas and
Outlying Islands. There should be some differences across these locations
in the decision of the TPB. Comparisons of the probit results between
New Towns and the other four regions would give some hints about the
decision making criteria of the TPB on New Towns’ planning
applications.
The TPB pointed out that there is a “presumption against
development” and “limited development” green belt policy. Thus,
intuitively, planning applications made in the Hong Kong Island,
Kowloon, and New Towns, which are urban areas, should be more likely
to be approved than those made in the less urbanized Rural Areas or
Outlying Islands. This is because development in the zones located near
or in the urbanized districts should exert less significant impact on the
natural environment than in rural zones.
15
Where applications fall into the nine urban new towns in Hong
Kong, they would be categorized as New Towns. Where the remaining
applications which fall into rural areas outside the urban new towns in a
DPA/IDPA/Rural OZP, they would be classified under Rural Areas.
Hypothesis I and II are related. If hypothesis I is not refuted,
hypothesis II is also not refuted and we could go further to investigate. If
hypothesis I is refuted, it means that the TPB does consider any location
factor when making decision. If hypothesis I is not refuted, we may
conclude that there is no difference across the location categories in the
decision of the TPB. If hypothesis II is refuted, we may conclude that
there are more severe restrictions on rural regions. If hypothesis II is not
refuted, we may conclude that there is no preference by TPB when
deciding on planning applications for uses in Green Belt zones in either
urban or rural regions. The remaining hypotheses would be tested by
using the second data pool (with 747 datasets).
Hypotheses III and IV further investigate the influence of location
factor in the Hong Kong’s new towns and its associated rural areas. Here,
we define the boundary of a new town in a different way and this is to be
distinguished from the urban New Town category in hypotheses I and II.
16
Here, each new town is consisting of both the urban new town areas (e.g.
in Sha Tin OZP, S/ST/20) and their rural hinterland (e.g. in Sha Tin
Kwun Yam Shan & Fa Sam Hang rural OZPs, S/ST-KYS/8) as a whole.
But in Hypotheses I and II, Sha Tin OZP, S/ST/20 and Sha Tin Kwun
Yam Shan & Fa Sam Hang rural OZPs, S/ST-KYS/8 would be separately
classified respectively as New Town and Rural Areas.
Using the same rationale for hypotheses I and II, it is hypothesized
that the chance of success of planning applications for uses in GB zones
in the in urbanized new towns would be easier than less urbanized new
towns. That means, applications made in the first generation new towns
should be the easiest to be approved and those in the third generation new
towns should be the easiest to be rejected.
Hypotheses III and IV are also related. If hypothesis III is not
refuted, hypothesis IV is also not refuted and we could go further to test it.
If hypothesis III is refuted, that means the TPB does consider the vintage
of new towns as a factor when deciding on planning applications. If
hypothesis III is not refuted, we may conclude that there is no difference
across the different generations of new towns in the decision of the TPB,
irrespective the degree of urbanization. If hypothesis IV is refuted, it
means that the TPB does consider the age of a new town when approving
17
or rejecting planning applications for uses in Green Belt zones. We may
also conclude that the more urbanized new towns are easier to get
planning approvals than less urbanized new towns. If hypothesis IV is not
refuted, it means that the TPB does not consider the age of new towns
when granting planning approvals, irrespective their degree of
urbanization.
Hypothesis V is to test the relevance of the scale/size of
development and the rent-seeking argument by various researchers (Chau
et al 1996; Chau and Lai 2003; Lai 1997a, b; Lai and Ho 2001a, b, c,
2002a, d, 2003; Staley 1994) of the inherent favour of the planning
permission mechanism towards larger developers as well as whether the
criterion of measuring “limited developments” in Green Belt zones is
based on proposed GFA (Lai and Ho 2001d). As greater GFA involves
more capital, it is used as a proxy for a larger developer, which is more
resourceful in lobbying the planning authorities than a smaller one.
Previous research (Tang and Choy 2000; Tang et al 2000; Lai and Ho
2001a, b, c, 2002b, d, 2003) showed that the scale of development as
represented by GFA is significant.
If Hypothesis V is refuted, i.e. larger development stands higher
chances of success in planning applications, then there is prima facie
18
evidence for the existence of rent-seeking activities within the planning
permission mechanism (Lai and Ho 2002d, 2003; Chan 2003; Yung
2004). If Hypothesis V is not refuted, then there is no prima facie
evidence of rent-seeking behaviour as far as Green Belt zones are
concerned. If the smaller the amount of floor space, the greater is the
chance of success, then we may conclude that there is a real policy of
‘presumption against development’ and ‘limited development’.
Hypothesis VI evaluates the land use factor to test whether there is
preference of TPB for Village Type House (VTH) over ordinary
residential development.
In the New Territories, some categories of buildings –Village Type
Houses (VTH), one type of ‘New Territories Exempted Houses’ (NTEH),
are outside the reach of the Buildings Ordinance5 (Lai 2000a; Lai and
Fong 2000; Lai and Ho 2001a, d). This is different from the ordinary type
of residential developments for which approval of building plans under
the Buildings Ordinance is needed. In the study of Lai and Fong (2000),
the VTH use has been very popular in Green Belt zones accounted for
40% of all GB applications. The average success rate of VTH
5. Chapter 123, Laws of Hong Kong.
19
applications may be greatly affected by the TPB’s policy towards small
houses in GB zones. On the other hand, applications related to residential
development other than VTH, were classified under either
‘Commercial/Residential’ or ‘Residential’ and the success rates of these
two uses were rather extreme.
Under the land administration policy, a ‘small house’ could be
applied for only by an adult male villager residing in an ‘indigenous
village’ in the New Territories of Hong Kong recognized by the colonial
administration (Lai 2000; Nissim 1999). Under this special land policy, a
small house can be applied for on any private land or, in case the
applicant has no land, government land at no premium, in village-type
development (V) zones. Outside the V zones, it can be built in a host of
zones but there are most applications found in Green Belt zones (Lai
2000). Lai and Ho (2001d) studied the chances of success in obtaining
planning permissions for the development of ‘small houses’ and ordinary
houses in all green belt zones in Hong Kong. They concluded that the
TPB favoured VTH and discriminated against the development of
ordinary houses in their study period. We should re-test this argument
here.
20
If hypothesis VI is refuted, we may conclude that TPB treats ‘small
house’ and ordinary house applications in an asymmetric manner. In this
hypothesis, if ‘small house’ applications stand a greater chance of success,
then we may conclude that the ‘small house’ is exempted from the
‘general presumption against development’ in green belt zones or that the
accommodation of the ‘small house’ policy constitutes a ‘strong planning
ground’ which merits approval support. If hypothesis VI is not refuted,
we can say that there is no preference by TPB for Village Type House
over ordinary residential development.
Hypothesis VII tests the land use factor, i.e. whether there is
preference by TPB for ordinary residential developments over other uses6.
There are usually more than one land uses other than residential types of
development in Column 2 in the Notes to a statutory town plan7. There
should be difference in the scale of development if we compare
residential developments with those other uses. The difference in the
scale of development would affect the decision of the TPB in deciding on
6. Other Uses are defined as development other than VTH developments and
other ordinary residential development like “Residential”, “Residential/Commercial, etc. (Town Planning Board 2004).
7 . For example, Utility Installations, Petrol-Filling Station, Open Storage,
Religious Institution, Warehouse, Container-Related, etc. (Town Planning Board 2004).
21
planning applications. Ordinary residential development usually involves
a larger GFA, compared with other uses, which should be less welcomed
by the TPB is the light of “limited development” policy on the Green Belt
zones.
If Hypothesis VII is refuted, we may conclude that the TPB has
preference for either ordinary residential development or other uses. If
Hypothesis VII is not refuted, we may conclude that the TPB has no
preference for ordinary residential development or other uses when
making planning decision (approval or rejection).

CHAPTER 4
METHODOLOGY
Modelling Planning Applications8
In a regression model, there are two kinds of variables: dependent
variables and independent variables. We would like to explain the
unknown (dependent) variable in terms of the known and measurable
(independent) variables (Wooldridge 2003).
Following the methodology of various researchers (Amemiya 1986;
Chau and Lai 2004; Lai and Ho 2001a, b, c, d; 2002a, b, c; 2003; Lee &
Trost 1978; Theil 1971; Tobin 1975) of modeling a dichotomous
dependent variable, this dissertation uses an econometric probit model to
evaluate planning application statistics in Hong Kong in terms of the
hypotheses discussed previously.
The probit model is used for analyzing the determinants of the
choice between two discrete alternatives, 1 or 0. The dependent variable
in our models is the decision (DEC) of the Town Planning Board which is
the results of the planning application. Hence, there are only two
8. This part is informed by Lai and Ho (2000) and Yung (2001).
23
outcomes in a case, either approval (dependent variable takes the value of
“1”) or rejection (dependent variable takes the value of “0”). The cases of
delay and withdrawal would be excluded from the data set because there
were no decisions made. Only the latest application for each lot will be
taken into account to avoid double counting (Anderson 1981; Sellgren
1990).
While the independent variables that generates such outcomes can
be any values. Where the dependent variable can take only limited values,
linear probability model would not be able to model such a relationship.
While the probit model, a discrete choice model would be a good choice.
A univariate binary qualitative response model is defined by the
following equation:
(4.1) p(yi = 1) = F(xi’ βo)
where i = 1,2,…,n, and {yi is a sequence of independent binary random
variables taking the value of 1 or 0, xi is a K-vector of known constants,
βo is a K-vector of unknown parameters, and F is a certain known
function.
24
It would be more general to specify the probability as F(xi, βo), but
the specification (4.1) is the most common. As in the linear regression
model, specifying the argument of F as xi’ βo is more general than it
would seem because the elements of xi can be transformed from the
original independent variables (Amemiya 1986). To a certain extent, a
general non-linear function of the original independent variables can be
approximated by xi’ βo, and the choice of F is not critical as long as it is a
distribution function. An arbitrary distribution function could be attained
by choosing an approximate function H in the specification F[H(xi’ βo)]
The function forms of F can be used in application of linear
probability model, probit model and logit model. The probit model of
planning applications can be specified as the equation below:
(4.2) p(xα1, xα2, …, xαj) = F(βo + β1 xα1 + β2 xα2 +…+ βj xαj)
= 1/(2π)-0.5 ∫-∞βo + β1xα1 + β2xα2 +…+ βjxαj exp[(-1/2) t2]dt
Or equivalently,
(4.3) F-1 (p(xα1, xα2, …, xαj)) = βo + β1 xα1 + β2 xα2 +…+ βj xαj
25
Since the dependent variable yi is unobservable, the Ordinary Least
Square (OLS) method could not be used, and we choose the Maximum
Likelihood method here. There are only 2 possible outcomes in this case:
approval (y=1) or rejection (y=0), and all the town planning applications
are independent of each other. Therefore, we can apply the binomial
distribution to find the likelihood of happening of a particular event. The
probability of a successful planning application is modeled as a function
of the specific use applied for, the proposal gross floor area (GFA) and
locations (detailed descriptions of independent variables of the model in
this dissertation would be provided in later sections). Let xα1, xα2, …,
xαj be the values taken by these variables for the αth planning application.
To estimate the parameters βo, β1, β2, …, βj, we should apply Maximum
Likelihood method. The observations are arranged in such a way that the
first n’ applications are approved by the Town Planning Board, and the
last n-n’ applications are rejected. Then, the logarithmic likelihood
function can be written as:
(4.5)
Where each p(xα1, xα2, …, xαj) is of the form Equation (4.2) and is thus
a function of βo, β1, β2, …, βj. By differentiating Equation (4.5) with
26
respect to these parameters and equating the derivatives to zero, non-
linear equations are obtained from which estimates can be derived
numerically by an iterative procedure (Theil 1971).
Data Description
Records of planning applications in the Green Belt zones from
years 1975 to 2004 are extracted from the database of the Planning
Department9. Therefore, data including the latest planning applications
made in the year 2004 of altogether 30 years’ planning applications
would be employed in this dissertation.
Two different data pools would be used in this dissertation to
construct two models for hypotheses testing. The testing of Hypotheses I
and II would employ data sets of Green Belt zones, which include
planning applications for all kinds of development in all districts
throughout Hong Kong (Hong Kong Island, Kowloon, New Territories
and Outlying Islands). There are altogether 1275 sets of data in this pool
in respect of Green Belt zones in Hong Kong.
9 . The data for the years 1975 to 1998 has collected from the Planning
Department by Lai and Fong (2000). The remaining data from 1999 to 2004 has extracted manually by the author and other students from the Department of Real Estate and Construction, Faculty of Architecture, the University of Hong Kong as Research Assistant to Professor Lawrence Lai.
27
The testing of Hypotheses III to VII would make use of data sets of
green belt zones of planning applications for all kinds of development
only in the urban New Towns and also the Rural Areas associated with
respective New Towns (e.g. The Kwun Yam Shan & Fa Sam Hang
Outline Zoning Plan is a Rural OZP which is associated with the Sha Tin
new town). Applications in Hong Kong Island, Kowloon, Outlying
Islands and some of the Rural Areas which are not associated with New
Towns were excluded. Moreover, due to incomplete data provided in
some data sets for proposed Gross Floor Area, a small number of sets of
data are also abandoned and hence there are altogether 747 data sets used
in this pool.
In the current study, there are four types of independent variables.
Firstly, in order to compare the four broad regions with the urban New
Town region, we define four dummy variables for the four different broad
districts: HK = 1 if the site is located in Hong Kong Island, 0 if otherwise.
KLN = 1 if the site is located in Kowloon, 0 if otherwise, ISLAND = 1 if
the site is located in outlying islands, 0 if otherwise. RURAL = 1 if the
site is located in rural areas, 0 if otherwise. For applications falling in
different generations of new towns, we define the following dummy
variables: FIRST = 1 if the site is located in the first generation new
towns, 0 if otherwise. THIRD = 1 if the site is located in the third
28
generation new towns, 0 if otherwise. GFA represents the proposed gross
floor area (square metre) of a site under application. For different uses,
two dummy variables are set for the analysis as follows: VTH = 1 if the
case is applied for ‘Village Type House’ Use, 0 if otherwise. OTHERS =
1 if the case applied fall in the uses other than ‘Village Type House’ or
‘Ordinary Residential Developments’ uses, 0 if otherwise.

CHAPTER 5
EMPIRICAL ESTIMATES & DISCUSSIONS
Empirical Estimates
Two different probit models, employing two different data pools
and different independent variables, would be analyzed individually
below.
First Model (all applications regarding GB zones in Hong Kong)
In Table 1, the probit estimates of the decision functions of the
TPB are presented.
Table 3. Probit results for the first model Dependent Variable: DEC Method: ML - Binary Probit Date: 12/06/04 Time: 15:07 Sample: 1 1275 Included observations: 1275 Convergence achieved after 3 iterations Covariance matrix computed using second derivatives

The coefficients of the four broad regions, HK, KLN, RURAL and
ISLAND, are all significant (1% significant for HK, KLN, RURAL and
5% significant for ISLAND). This suggests that the Town Planning
Board does consider location factor in making its decisions regarding
planning applications. Hypothesis I is refuted. There are differences
among various location categories in the decision of the TPB.
The coefficients HK, KLN and ISLAND are all positive, indicating
that a planning application made in these three broad regions would be
more likely to be approved compared with the urban New Town region.
To the contrary, the coefficient of RURAL is negative, indicating that a
planning application made in this broad region, when compared with the
New Towns, HK, KLN and ISLAND, would be more likely to be rejected.
It is surprising to find that the coefficient of ISLAND is positive, which is
not consistent with our preliminary estimation. This could perhaps be
explained in the following was the majority of the planning application
31
cases for ISLAND were made in the more urbanized areas in Lantau
Island (e.g. Chek Lap Kok, etc. which is near the Chek Lap Kok Airport)
where there are quite a lot of existing development and where most of the
housing stocks are developed and managed by the Mass Transit Railway
(MTR). Moreover, since there were fewer applications made in ISLAND
than New Towns which affects the result. The result could be more
reliable if there were more applications made in ISLAND. Hypothesis II
is refuted. Planning applications made in more urbanized areas were
easier to get approvals and those in rural Green Belt zones had a higher
chance of meeting failure than those in GB zones in urban districts.
Second Model (all applications regarding GB zones in Hong Kong’s
New Towns)
In Table 2, the probit estimates of the decision function in the
green belt zones in New Towns are presented. It is the optimal equation10
with the highest McFadden R-Squared value.
10. We apply log function to the independent variable GFA. This method is
usually done in previous researches (Chau and Lai 2003; Lai and Ho 2001a, b, d; 2002b, c; 2003). They found that the optimal equation may be a semi-log or log function. The McFadden R-squared value has also improved a lot after taking the log function. This equation contains most significant variables and has the highest McFadden R-squared value. It is regarded as the optimal equation from the data available.

The coefficient of FIRST is negative but insignificant. This implies
that whether an applications was made in a first generation new town (i.e.
Sha Tin, Tsuen Wan or Tuen Mun) or a second generation new towns (i.e.
Tai Po, Fanling/Sheung Shui or Yuen Long), had no significant impact on
the decision of the Town Planning Board. This is possibly because both
first and second generation new towns had already been heavily
urbanized. Therefore, when TPB is making a decision, it has no
33
preference in respect of the age. The coefficient of THIRD is negative
and significant at 1% level. This implies that the Town Planning Board
would readily reject a planning application made in a third generation
new town than one made in a second generation new town. Therefore,
hypothesis III is refuted. The TPB did consider age of a new town when
making planning decisions and the more urbanized is the new town, the
easier is the granting of planning approvals. In other words, hypothesis
IV is refuted.
The coefficient for the variable GFA is found to be negative and
significant at 1%. This means that an application for uses in larger sites
had a greater chance to be rejected than one in a smaller site in a Green
Belt zone in Hong Kong’s new towns. In other words, Hypothesis V is
not refuted and there is no prima facie evidence to support the argument
that there are rent-seeking activities within the TPB. TPB even
discriminates against larger development and we may therefore conclude
that planning policy of ‘presumption of against development’ and
‘limited development’ in the Green Belt zones has been adhered to by
TPB.
For Village Type House (VTH) development, the coefficient is
positive and significant at 1%. This suggests that a planning application
34
for Village Type House in a Green Belt zone within a Hong Kong’s new
town is associated with a greater likelihood of being approved by the TPB
when compared with an rdinary residential development. In other words,
Hypothesis VI is refuted. This is an expected result, since Village Type
House is a small-scale and low-density type of development compared
with ordinary residential development. It is easy to understand why the
TPB favoured this type of development because there should be little
impact created by individual small houses on the environment. This result
confirms our previous results on GFA where TPB was found
discriminated against development with larger GFA.
For other types of uses, the coefficient OTHERS is positive and
significant at 1%, indicating that the TPB generally showed
discrimination against ordinary residential development over OTHERS.
In other words, hypothesis VII is refuted. This is also an expected result.
If we compare the proposed GFA of ordinary residential development and
OTHERS, we would probably find that ordinary residential development
generally involves larger GFA (a larger scale of development). This result
further confirms our previous results about GFA and VTH where TPB
was found discriminated against development with larger GFAs.
35
CHAPTER 6
CONCLUSION
The objectives of this study are to investigate the criteria of TPB
when approving planning applications by following the probit
methodology of previous researchers (Chau and Lai 2004; Lai and Ho
2000; 2001a, b, c, d; 2002a, b, c, d; 2003) in the context of Green Belt
zone with the focus on Hong Kong’s new towns.
The results show that application for uses in GB zones in urbanized
areas appeared to stand a higher chance to be approved than the less
urbanized, or even rural areas. This is shown by the results that planning
applications made in the four broad regions (Hong Kong, Kowloon,
outlying islands and New Towns) are easier to be approved than
applications made in Rural Areas in Hong Kong. This is also confirmed
by the result that the Town Planning Board would be more readily to
reject a planning application made in a third generation new town than
one made in a second generation new town (and the second generation
new town is more urbanized). This is because development in the zones
located near or in the urbanized districts should exert less significant
impact on the natural environment than in rural zones. However, the TPB
36
is not sensitive to whether a planning application is made in a first
generation or second generation new town.
Larger-scale development appeared to stand a smaller chance to be
approved than the smaller-scale one. There is no evidence that there was
rent-seeking behaviour in the development control mechanism with
regard to Green Belt zones in the new towns. But the attitude of the TPB
was different while facing applications of VTH, ordinary residential
development and other uses. The results also suggest that the planning
policy of ‘presumption against development’ and ‘limited development’
is a valid one in Green Belt zones within Hong Kong’s new towns.
Development of VTH was preferred over ordinary residential
development and the TPB also had preference for other uses over
ordinary residential development. Residential development generally
involves a larger GFA than VTH and other uses. Thus they are
unwelcome by the TPB.
The results of the hypotheses give us good empirical evidence to
confirm that the official restrictive development control policy for the
Green Belt zones is actually applied in the Hong Kong’s new towns.
37
Quantitative study on Hong Kong’s new towns using non-
aggregated data has not been given much interest in the past. Therefore,
as a first focused attempt, this dissertation has investigated applications
for uses under green belt zoning in Hong Kong’s new towns. It is hoped
that this empirical study would kindle a new interest in new town study.

APPENDIX I
PHOTOGRAPHIC ILLUSTRATIONS OF FINDINGS
In this appendix, photographs taken by the author are shown in
order to illustrate and help interpret the findings (the seven hypotheses
with respect to Hong Kong’s new towns) in this dissertation.
Hypotheses I and II
The results of the two hypotheses show that the TPB has different
preferences towards different location categories (different broad regions)
in Hong Kong when considering applications regarding Green Belt zones
and urbanized areas (e.g. Hong Kong Island and New Towns) appeared to
stand a higher chance to be approved than the less urbanized areas (Rural
Areas). This could be illustrated by the following photographs:
39
Photograph 1. The Leighton Hill in Causeway Bay. (Date taken: 11/3/2005)
Photograph 2. The Ho Chung New Village in Sai Kung. (Date taken: 13/3/2005)
40
Both residential developments shown in photographs 1 and 2 are
situated in Green Belt zones. The Leighton Hill is situated in Hong Kong
Island whereas the Ho Chung New Village Sai Kung rural areas. We
would probably notice that the Leighton Hill development is more
extensive in scale whereas the development in the rural Green Belt is
smaller in scale. This showed that larger development is more likely to be
approved in urban Green Belts (The Leighton Hill in Hong Kong Island)
than in rural ones (the Ho Chung New Village). This confirms the result,
that due to the “presumption against development” and “limited
development” green belt policy, planning application regarding Green
Belt zones made in the urban areas, should be more likely to be approved
than those made in the less urbanized areas.
Hypotheses III and IV
The results of the two hypotheses show that the TPB has different
preferences towards different location categories (different vintages of the
new towns) and applications in more urbanized new towns appeared to
stand a higher chance to be approved than the less urbanized new towns.
41
Photograph 3. Sha Tin New Town (a first generation new town). (Date taken: 11/3/2005)
Photograph 4. Tai Po New Town (a second generation new town). (Date taken: 11/3/2005)
42
Photograph 5. Sai Kung New Town (a third generation new town) (Date taken: 13/3/2005)
Photograph 6. Eden Gardens (ordinary residential building in a Sha Tin Green Belt zone) (Date taken: 11/3/2005)
43
Photograph 7. Village Type Houses in Ho Chung Village (Sai Kung) (Date taken: 13/3/2005)
Photographs 3, 4 and 5 show different vintages of new towns in
Hong Kong. From the photographs, it is not hard to notice that the degree
of urbanization of the first and second generation new towns are roughly
the same (represented by Sha Tin and Tai Po respectively) and the third
generation new town (represented by Sai Kung) is less urbanized.
Moreover, both the residential developments shown in photographs
6 and 7 are situated in Green Belt zones in the respective new towns. The
Eden Gardens is situated in Sha Tin new town whereas the Village Typed
Houses in Ho Chung Village is situated in Sai Kung. We would probably
44
notice that the Eden Gardens development is more extensive in scale with
high-rise residential towers whereas the Village Type House development
in Ho Chung Village is smaller in scale. This shows that larger
development in Green Belt zone is more likely to be approved in more
urban new towns than in less urban ones. Our previous statistical result is
confirmed and it is because of the “presumption against development”
and “limited development” green belt policy.
Hypotheses V, VI and VII
The result of hypothesis V points out that Decision-makers
regarding planning applications made in Green Belt zones in Hong
Kong’s new towns may not be affected by rent-seekers as they indeed
discriminate larger development. The presumption against development
and limited development planning policy can be said to apply to Green
Belt zones in Hong Kong’s new towns.
The result of hypothesis VI affirms the findings of Lai & Ho
(2001a, d) that the TPB treats planning applications for different uses in
an asymmetric manner that (preferring VTH to ordinary residential
developments). Whereas the result of hypothesis VII shows that the TPB
treats planning applications for different uses in an asymmetric manner
(preferring other uses (e.g. open storage, car parks, etc.) to ordinary
45
residential developments). The results could be illustrated by the
following photographs:
Photograph 8. Village Type House (Date taken: 13/3/2005)
Photograph 9. Religious Institution (Other use) (Date taken: 13/3/2005)
46
Photograph 10. Car Park (Other use) (Date taken: 13/3/2005)
Photograph 8 shows a typical Village Type House in Sai Kung Ho Chung
Village. In photograph 5, we would note that the majority of buildings in
Sai Kung new town (a more rural third-generation new town) are low-rise.
After a recent site visit in 13/3/2005, the author found that Village Type
House is the most common form of residential building to be found in
such more rural new towns as Sai Kung. In addition, photographs 9 and
10 show the common other uses (religious institution and car park) in
more rural new towns. It is relatively uncommon to see the uses shown by
photographs 9 and 10 in urban areas and it is hard to find high-rise
buildings in rural areas. Moreover, the Gross Floor Area (GFA) of
Village Type Houses and other uses are seen to be much smaller than
47
ordinary residential development. This confirms our previous statistical
results, that due to the “presumption against development” and “limited
development” green belt policy, planning application regarding Green
Belt zones with smaller GFA (e.g. VTH and other uses), should be more
likely to be approved than those developments with larger GFAs in Hong
Kong’s new towns.
Concluding Remarks
The author conducted site visits in Causeway Bay, Pokfulam, Sha
Tin, Tai Po and Sai Kung on 11/3/2005 and 13/3/2005. The photographs
are taken during the site visits It is hoped that the photographs would help
illustrate and reinforce the statistical findings in this dissertation.
