Plant Productivity Dynamics and Private and Public R&D Spillovers:

Technological, Geographic and Relational Proximity

ABSTRACT

We examine the effects of R&D spillovers on total factor productivity in a large panel of

Japanese manufacturing plants matched with R&D survey data (1987-2007). We

simultaneously examine the role of public (university and research institutions) and private

(firm) R&D spillovers, and examine the differential effects due to technological, geographic

and relational (buyer-supplier) proximity. Estimating dynamic long difference models and

allowing for gradual convergence in TFP and geographic decay in spillover effects, we find

positive effects of technologically proximate private R&D stocks, which decay in distance

and become negligible at around 500 kilometres. In addition to knowledge spillovers from

technologically proximate R&D stocks, ‘relational’ spillovers from buyer and supplier R&D

stocks exert positive effects on TFP growth that are similar in magnitude. The elasticity of

TFP is highest for public R&D (corrected for industrial relevance), in particular for plants

operated by R&D conducting firms. We do not find evidence of geographic decay in the

impact of public and relational spillovers. Over time, declining R&D spillovers appear to be

responsible for a substantial part of the decline in the rate of TFP growth. The exit of

proximate plants operated by R&D intensive firms plays a notable role in this process and is

an important phenomenon in major industrial agglomerations such as Tokyo, Osaka, and

Kanagawa.

1. Introduction

It is well established in the literature that the productivity effects of R&D spillovers are

enhanced by technological proximity and geographic proximity (Jaffe et al., 1993; Adams

and Jaffe, 1996; Aldieri and Cincera, 2009; Lychagin et al., 2010; Bloom et al., 2013;

Orlando, 2004; Griffith et al., 2009; Mairesse and Mulkay, 2008). Despite the increasing

number of large-scale firm-level studies on R&D spillovers,1 existing studies have a number

of limitations in scope and methodology. First, they typically relied on data on publicly listed

firms, aggregating over the various locations and technologies in which firms are active.2

Second, the focus has been on inter-firm private spillovers while abstracting from the role of

public research. A different research stream focusing on the role of knowledge spillovers

from public research conducted at universities and research institutes has however suggested

the importance of such spillovers, with an explicit role of proximity (e.g. Jaffe, 1989; Adams,

1990; Anselin et al., 1997; Furman et al., 2005). Third, R&D spillovers at the firm level have

in most cases been modelled as knowledge spillovers as a function of proximity between

technology portfolios of the firm, while the role of spillovers through supplier and customer

linkages has only received limited attention.3 A separate literature on the role of spillovers in

the context of foreign direct investments has strongly suggested that 'vertical' spillovers

through buyer-supplier relationships often is the key channel through with spillovers occur

(e.g. Haskel et al., 2007; Görg and Strobl, 2001; Javorcik, 2004; Kugler, 2006). While

knowledge and technology transfer in these relationships is often purposeful and embedded in

intermediates, their value tends not to be fully reflected in the price of such intermediates,

leading to ‘pecuniary spillovers (Hall et al., 2012; Crespi et al, 2007). Compared with

‘horizontal’ spillovers in technological proximity within narrowly defined industries, the

absence of market rivalry provides greater incentives for productivity and growth enhancing

knowledge exchange and spillovers (e.g. Bloom et al., 2013). Since suppliers and clients may

be active in a variety of industries, these 'relational' spillovers are yet a different dimension of

heterogeneity in spillover pools.

This paper addresses these limitations in prior work. We contribute an analysis of the

1 Early work examined R&D spillovers at the industry level (e.g. Mohnen and Lepine, 1991; Audretsch and

Feldman, 1996; Goto and Suzuki, 1989). 2 Adams and Jaffe (1996) do analyse plant level productivity but focuses on the effects of internal R&D. The

analysis of Griffith et al. (2009) for UK plants focuses on proximity effects but does not incorporate the role of

R&D. 3 An exception is Crespi et al. (2007), who examine data from UK Community Innovation Surveys for direct

(self assessed) evidence of incoming knowledge flows at the firm level. They find, among others, that supplier

information positively affects TFP growth, but do not examine geographic or technological proximity.

various sources of R&D spillovers, which until now have not been considered simultaneously,

and examine these relationships at the plant level. We analyse the effects of technologically,

geographically, and relationally proximate private R&D stocks, as well as of technologically

and geographically proximate public R&D stocks on TFP in an unbalanced panel of close to

20000 Japanese manufacturing plants, 1987-2007. The plant level data from the Census of

Manufacturers are matched with information on R&D expenditures from the comprehensive

Survey of R&D Activities in Japan covering virtually all R&D spending firms (and public

research institutions). The R&D survey data, which are decomposed by field or industry of

application, allow us to construct relevant R&D stocks weighted by technological proximity

(e.g. Bloom et al., 2013), while the information on plant locations allows us to explore the

role of geographic distance between firms and between firms and public research institutions

in much more detail than in previous studies. Relationally proximate R&D stocks are

calculated using input-output tables. Public R&D stocks are differentiated by science field,

which can be mapped into technologies and industries reflecting their varying relevance for

firms. We estimate long (five year) difference models of plant TFP growth to reduce the

influence of measurement errors and cyclical effects (e.g. Haskel et al., 2007; Branstetter,

2000). We allow for gradual convergence in TFP by estimating dynamic TFP growth models

(e.g. Klette, 1996; Klette and Johanson, 1998; Lokshin et al., 2008), and we identify distance

effects by estimating exponential decay parameters (e.g. Lychagin et al., 2010; Duranton and

Overman, 2005)). The simultaneous inclusion of multiple sources of spillovers, the detail on

location and field of R&D, the long panel, and the uniquely large set of plants should allow

more precise estimates of spillover effects and an assessment of their relative importance over

time. Our study contributes to the very limited literature on R&D and spillovers at the plant

level.

Our research is also motivated by the observation that Japan's total factor productivity

growth has been declining since the mid-1980s (e.g. Fukao and Kwon, 2011), while at the

same time R&D expenditures as a percentage of GDP have been steadily increasing to reach

3.8% in 2008, from 2.5% in 1980s. The discrepancy between the trends in R&D expenditures

and TFP suggests that the aggregate returns to R&D have been falling. One possible

explanation for this phenomenon may be a decline in R&D spillovers due to the exit (and

potential relocation abroad) of sophisticated manufacturing plants of R&D intensive firms

and the accompanied changing patterns of R&D agglomeration, which may have reduced the

size and effectiveness of the relevant pool of R&D spillovers across firms. Prior studies

suggest that exit rates of relatively productive plants operated by multi-plant (multinational)

firms have been typically higher than the exit rates of single establishments (e.g. Fukao and

Kwon, 2006; Kneller et al. 2012).

The remainder of the paper is organized as follows. The next section describes the model,

the particularities of the data and the empirical strategy followed. Section 3 presents the

empirical results and section 4 concludes and discusses avenues for future research.

2. Model Setup and Data

We conduct a plant-level panel analysis of total factor productivity, in which we relate

plant-level TFP to firms’ own R&D stock, private R&D stocks (the private spillover pool),

public R&D stocks, and a set of plant-, firm- and industry-level controls. We assume that firm

level R&D stocks are available to all the firms’ plants and that R&D spillovers occur between

plants due to the R&D stock the plants have access to. This allows us to investigate the

geographic dimension of R&D spillover in detail, taking into account the population of R&D

conducting firms and the spatial and industry configuration of their plants.

We adopt the standard knowledge stock augmented production function framework (e.g.

Hall et al, 2012). We define the production function at the plant-level generally as:

(1)

Where:

: Gross output of the plant

: Inputs of plant in year

: Firm-level R&D stock

: Private R&D stock

: Public R&D stock

: a vector of other observable factors (control variables) affecting plant

productivity

: plant-year specific unobserved efficiency.

Total factor productivity (TFP) is defined as:

(2)

Page 7: Center for Economic Institutions Working Paper Seriescei.ier.hit-u.ac.jp/Japanese/pdf/wp_2013/wp2013-5.pdf · In addition to knowledge spillovers from technologically proximate R&D

R&D stocks are assumed to influence production with a one-year lag to reflect that the

application of new knowledge and insights due to R&D takes time. If we adopt a log-linear

specification for and allow , where is a plant specific

fixed effect and is a plant-year specific efficiency shock, we obtain:

(3)

and if we difference the equation between two periods:

(4)

where the plant-specific efficiency parameter drops out. We assume that the change in plant-

specific efficiency levels ) is a function of past productivity relative to the industry

mean, in order to allow for a gradual convergence in efficiency levels between firms (e.g.

Lokshin et al., 2008). Klette (1996) and Griffith et al. (2009) have shown that the empirically

observed persistent productivity differences between plants or firms require a model

specification that allows for gradual convergence.4 Specifically, we model:

(5)

where is the level of TFP of plant relative to the industry mean in the previous

period. We expect to fall within the interval [-1,0]. If is zero there is no gradual

convergence between leading firms and lagging firms; if is –1 complete convergence

materializes in one period. We assume that the error term can be decomposed into four

components, year-specific effects , industry-year specific technological opportunity or

efficiency shocks (with s denoting industry), regional shocks and measurement error

:

manufacturing plants as well

Data sources and sample

We match plant level data from the Japanese Census of Manufacturers with information

on R&D expenditures from the yearly (comprehensive) Survey of R&D Activities in Japan,

1987-2007. The census has a comprehensive coverage of manufacturing plants with more

than 4 employees. From 2001 onwards, information on plant level fixed capital investment

has not been surveyed for plants with less than 30 employees, with the exception of the

benchmark surveys organized every 5 years. The number of plants for which panel data on

TFP can be calculated is roughly 40,000 yearly.

The Survey of R&D activities in Japan is a comprehensive and mandatory survey of

R&D performing firms and public research institutes and universities in Japan. It contains

information on R&D expenditures, differentiated by field, for roughly 9,000 firms yearly and

has a response rate greater than 90 percent. Large firms (with more than 1 billion Yen of

capital) are always included in the survey; smaller firms are included in higher sampling rates

if they are identified as R&D conducting firms in the previous survey. The information on

R&D by field (30 fields are distinguished) is easily mapped into industries, and allows us to

distinguish R&D expenditures relevant to 20 manufacturing industries. The response rate by

research institutes and universities is close to 100 percent.

The matching between the surveys posed a number of challenges. Firm names are only

recorded in the R&D survey from 2001 onwards and parent firm names are only provided on

the plant records in the census from 1994 onwards. Firm identifiers in the R&D survey are

not compatible between the years before and after 2001 because the identifiers for all firms

were revised in 2001; only the R&D survey in 2001 includes both the old and new versions

of firm identifiers. Because of the absence of common firm identifiers in the surveys,

matching had to be done semi-manually (by firm name, address and capitalization). From

2001 onwards, we could match more than 97.5 percent of reported R&D expenditures to

firms and plants included in the census (Figure 1). The situation is more complicated for the

years 1983-2000, for which we could only match R&D to plants 1) that could be linked to the

parent firm in 1994 or one of the later years, and 2) that belong to firms identified in the R&D

survey of 2001. This caused the coverage rate to decline from 98 percent in 2001 to 92.5

percent in 2000, declining progressively further to 73 percent in 1983.

The matching issues cause several problems. First, there is a difficulty ascertaining

whether a plant belongs to a parent firm conducting R&D or not. Here we excluded all

unmatched firms from our sample to avoid measurement error in R&D stocks at the firm

level. Second, for some firms R&D series are incomplete. We proceeded to calculate R&D

stocks on the basis of the information available only if there was sufficient information to

derive an R&D growth rate for a specific period. Firms that are included in the R&D survey

multiple times reporting absence of R&D activities are included in the sample with zero R&D

stock. Third, we require reliable estimates of private R&D spillover pools. Here we obtained

estimates that are as accurate as possible by 1) using the weights provided in the R&D survey

to correct for non-response and arrive at an estimate of total R&D expenditures in Japan; 2)

allocating the R&D (stocks) to locations and fields/industries for R&D conducting firms that

could not be matched to the manufacturing census (and hence for which no geographic

information on plants is available) on the basis of the location of the firm, rather than on the

basis of the location of plants. The second correction may be a reasonable approximation as

most of the unmatched firms are smaller enterprises for which the plant and administrative

unit are collocated.

Using the above matching rules, we obtain an unbalanced panel of over 19000 plants,

observed for a maximum of 20 years and a minimum of 5 years, during 1987-2007. The five

year minimum observation period is due to the fact that we will estimate (five-year) long

difference models. About 57 percent of the plant observations, plants are owned by parent

firms for which we could confirm the absence of formal R&D. Zero R&D cases are not

compatible with the specification in natural logarithms in (4) but provide important variation

in the sample. We deal with this in two ways: 1) we include a dummy for continuous

engagement in, or absence of, R&D; 2) we add the value 1 to the R&D stock before taking

the logarithm, such that we treat the continuous absence of R&D as zero growth.

Table 1 shows the distribution of plants over industries and compares this with the

distribution of the population of Japanese manufacturing plants over industries. Plants in

technology intensive industries such as drugs & medicine and chemicals are overrepresented

in our sample, but the difference with the distribution of all plants over industries is not

generally pronounced. The 19389 unique plants are operated by 13188 firms, implying that

on average there are 1.5 plant observations per firm in the sample. Parent firm R&D stocks

are highest in the home electronics and information and telecommunication sectors, and

lowest in pulp & paper and printing.

Insert Table 1

We note that creating a sample of plants for which parent firms’ R&D stocks can be

calculated leads to various sample selection issues, with a natural oversampling of R&D

conducting firms (although the majority of plants in our sample have no access to internal

R&D), larger plants (post-2001), surviving plants (1987-1994), and surviving firms (1987-

2001). We will conduct several sensitivity analyses to examine potential selection bias.

Variables and Measurement

We utilize plant level TFP data from the Japan Industrial Productivity Database (JIP)

2010 (Fukao et al., 2008). TFP is measured using the index number method, following Good

et al (1997):

(1)(7)

where Qfsi,t is the gross output of plant i of firm f in industry s in year t, sX

,fsi,t is the cost share

of input X, and Xfsi,t is the amount inputs of the plant. Three inputs, labour (L), capital (C),

and intermediate input (M), are taken into account. Variables with upper bars denote the

arithmetic mean of each variable over all plants in that industry s in year t. The JIP database

provides index linked TFP estimates distinguishing 58 industries. The TFP indices express

the plants’ TFP as an index of the TFP level of a hypothetical representative plant in the

industry (with an index of 1). One of the main advantages of the index number method is that

it allows for heterogeneity in the production technology of individual firms, while other

methods controlling for the endogeneity of inputs (e.g. Olley and Pakes, 1996; Levinsohn and

Petrin, 2003) assume an identical production technology among firms within an industry (Van

Biesebroeck, 2007; Aw et al., 2001).

Drawing on the JIP database, we calculate the five-year growth rate in TPF for the

matched sample. We drop the observations with the largest (top 1 percent) and lowest

(bottom 1 percent) TFP growth to avoid a potentially strong influence of outliers. Figure 2

shows the 5-year moving average of the gross output weighted average TFP growth rate for

the sample. The figure confirms that the rate of TFP growth has been decreasing over time,

while there is a modest recovery in growth rates after 1999. The pattern of TFP growth in the

sample closely follows the pattern of TFP growth in the population of Japanese plants.

R&D stocks by industry and location

R&D stocks measured at the parent firm level can be separated by industry/field of

application to arrive at R&D stocks of the firm per industry. We utilize a question in the R&D

survey asking firms to allocate R&D expenditures by field, which easily maps into 20

industries. R&D stock of firm in industry/field is defined by:

(8)

where is R&D investment of firm for activities in industry in year and is a

depreciation rate of the R&D stock. We use industry-specific depreciation rates to reflect

differences in the speed of obsolescence and technology life cycles. Industry specific

depreciation rates are based on Japanese official surveys of “life-span” of technology

conducted in 1986 and 2009 among R&D conducting firms5 and vary between 8 (food

industry) and 25 percent (precision instruments). To calculate initial R&D stocks (Hall and

Oriani, 2006), we similarly use industry-specific growth rates, which we calculate from the

R&D survey as average R&D growth rates per field in the 1980s. R&D investments are

deflated using a deflator for private R&D from the JIP database, calculated from the price

indices of the input factors for R&D expenditures for each industry; the deflator for public

R&D is obtained from the White Paper on Science and Technology.

Matching the field of firms’ R&D with the industry of the firms’ plants, we can calculate

R&D stocks across industries and space, where we assume that the R&D stock in a

field/industry is available to each same-industry plant of the firm. We map R&D stocks in

geographic space by using the information on the location of the plant, where we distinguish

more than 1800 cities, wards, towns, and villages.

Plant R&D stocks

We calculate plant R&D stocks as the R&D stock of the parent and assume that all parent

R&D provides relevant productivity improving inputs to the plants. Given that R&D at the

firm level is often organized to benefit from scope economies (e.g. Henderson and Cockburn,

1996; Argyres and Silverman, 2004) and involves active knowledge transfer to business units

5 See “White paper on Science and Technology” (1986, Science and Technology Agency) and “Survey on

Research Activities of Private Corporations” (2009, National Institute of Science and Technology Policy).

and plants, this may be a suitable assumption.6

Private R&D stocks (spillover pools)

Private R&D stocks (spillover pools) are derived from the calculated parent firms’ R&D

stocks, while we allow for geographic decay in the effectiveness of spillovers.

Technologically proximate R&D stocks are calculated based on the technological proximity

between the R&D field/industry of the plant and the industry of other plants. We define the

technologically relevant private R&D stock (spillover pool) as the sum total of other firms’

R&D assigned to their (nearest) plants in an industry, weighted by the technological

relatedness between the industry of the plants and the industry of the focal plant:

(10)

where:

: Minimum geographic distance between plant and the plant of firm in the

field in year ;

: the technological proximity weight;

: Weight for geographic proximity of plant to R&D stock firm for field

;

: a decay parameter, with .

If firms operate multiple plants, the R&D stock is only counted once using the plant with

the minimum distance to the focal plant, which avoids double counting of R&D. 7

We model

an exponential decay function in the effectiveness of spillovers with parameter to be

estimated, in line with recent studies (e.g. Lychagin et al. 2010). Distance d is the distance

between a pair of locations and is measured as the geo-distance between the centre of cities,

wards, towns, and villages. In order to correct for differences in the geographic areas covered

by the regions, distance is the radius of the region if plants are located in the same region.

6 We also calculated a technological proximity weighted parent R&D stock, applying the weighting scheme for

industries/fields outside the industry of the plant based on the technological proximity matrix used for R&D

spillovers, but obtained weaker effects. As the co-occurrence of different technologies in the R&D portfolios of

firms is often taken as an indicator of the potential for scope economies (Bloom et al. 2013; Breschi et al. 2003)

this is perhaps not surprising. 7 This would follow from the notion of redundancy in the type of R&D spillovers. On other hand, one may

argue that having multiple plants in the vicinity increases the likelihood of knowledge spillovers.

12

Our technological relatedness measure is derived from patent data and based on Leten et al.

(2007). The relatedness between technologies will be reflected in the intensity with which

technologies in a field build on prior art in a different field. Patent citation data are available

at the 4-digit IPC level. The IPC codes can subsequently be mapped onto industries using the

industry-technology concordance table developed by Schmoch et al. (2003) in which each

technology field is uniquely linked to its corresponding NACE two-digit industry. Appendix

A shows the resulting technological relatedness coefficients (weights) between industries

used in our analyses, with weights for the own industry normalized at 1.

We measure relationally proximate R&D stocks by the R&D stocks of supplier and

customer industries, identifying the importance of supplier and customer transactions from

Input-Output tables (yearly between 1987 and 2007) for 52 JIP industries. The calculation of

R&D stocks follows (10) but with substituted by supplier industry proximity weights

and customer proximity weights , with:

(12)

(13)

where denotes domestic sales of industry to industry and denotes exports of

industry . In equation (12), is the estimated output of industry sold to industry s.

Since domestic sales in the input-output tables include domestic sales of imported goods, we

estimate by applying the following correction to the domestic sales data:

, with imports of industry s. Hence we assume that the

imported goods of the industry are sold to other industries in proportion to total sales to these

industries. We note that industries s include services and other industries’ sales to industry s’,

such that the sum of input shares for industry s’ does not add up to 1. Weights for customer

R&D stocks for industry s are the shares of sales by industry s to industry in total sales,

with the latter including sales to non-manufacturing industries and exports. We use-yearly

input output tables provided by the JIP database, such that weights are varying by year.

Appendix B and C show the average the input and output share weights for the industries in

the analysis for the year 1990.

Public R&D stocks

13

Public R&D spillover pools derived from the R&D surveys have few measurement

issues, as response rates are virtually 100 percent. We differentiate public R&D by location

based on the region (city, ward, town, village) of the research institute or university, and by

industry/R&D field utilizing information on science fields with varying relevance for specific

industries. We define the R&D stock of public research institution in science field as:

(14)

where is research expenditure of public research institution in science field in year

and is a depreciation rate of public R&D stock, which we set at 15 percent per year.

Although the surveys do not include research expenditures by science field, they do contain

information on the number of researchers by science field for each institution for each year.

We estimate the public R&D expenditure by mutliplying total R&D expenditures with

the share of the number of scientists in the field in the total number of scientists for each

institution and year.

Second, we estimate a ‘relevant’ public R&D stock per industry/R&D field using weights

derived from a concordance matrix between science fields and industries. The weights are

based on a study by Van Looy et al. (2004) examining citation frequencies on patent

documents classified in different technology fields to Web of Science publications in each of

the science fields. The concordance attaches to each scientific discipline probabilities that it is

of relevance to each technology field (4-digit IPC fields). Applying this concordance to the

public R&D expenditures per science field, we subsequently apply the concordance matrix

between IPC classes and industries due to Schmoch et al. (2003) to arrive at public R&D

stocks per industry. Appendix D shows the compound weights used to relate R&D stocks per

science field to industries.

Using the above procedure, the technologically and geographically proximate public R&D

stock is defined as:

Figure 3 shows the 5-year moving average growth rates in the levels of public and private

R&D stocks. The growth in both public and private R&D shows a declining trend, as the

increase in overall R&D investments (Figure 1) has slowed over time and had just exceeded

deprecation rates in the most recent years.

Control variables

The vector of time varying plant-specific characteristics includes plant size (number of

employees) and a dummy variable indicating whether the plant is active in multiple industries

(at the 4 digit level).8 In addition, we control for parent firm size (number of employees) and

the number of plants of the parent firm. On the one hand, increases in the number of a firm’s

plants may correlate with unmeasured firm-specific advantages. On the other hand a larger

numbers of plants drawing on the same R&D pool may lead to reduced effective knowledge

transfer (Adams and Jaffe, 1996). We include a set of year dummies and region

(prefecture) dummies . We model as a set of industry dummies in addition to the

average TFP growth rate for all plants in the industry, , which controls for industry-

specific technological opportunity and demand shocks over time affecting TFP growth.

Specification

We estimate equation (4) in its long difference form. The long difference models, while

sacrificing degrees of freedom, is a conservative estimation method to reduce the influence of

measurement error and cyclical effects (e.g. Haskel et al, 2007; Branstetter, 2000). To strike a

balance between degrees of freedom and reduction in measurement error, we take 5-year

differences starting from 1987, which leaves a maximum of exactly 4 non-overlapping long

differenced observations (for plants observed over the entire period): 1987-1992, 1993-1997,

1998-2002 and 2003-2007. To facilitate interpretation of the descriptives, we divide the long

8 Note that age effects are of no interest in differenced models, since the difference in age would be identical for

all plants.

difference by 5 to arrive at annual average growth rates of TFP and R&D stocks during the 5-

year periods. Since the geographic decay specification introduces nonlinearity in the TFP

equation, we estimate equation (4) with nonlinear least squares. The distance decay

parameters are estimated using a Taylor approximation.9 Error terms are cluster-robust at the

plant level.

Table 2 shows descriptive statistics of the variables and Table 3 contains the correlation

matrix. The correlations between the (growth in) relationally proximate R&D stocks (buyers

and suppliers) and the technologically proximate R&D stock are rather high at 0.66-0.78.

This is mainly stemming from the correlation in same-industry R&D stocks, while

correlations between stocks in other industries range between -0.04 and 0.12. Hence, the

different measures of proximity do suggest rather different weightings for R&D stocks and

the resulting spillovers potential.

Insert Tables 2 and 3

3. Empirical results

Table 4 reports the estimation results. Model 1 only includes the technologically

proximate R&D stock and the parent firm R&D stock. The coefficient on parent R&D

suggests an elasticity of TFP with respect to R&D of 0.033 percent, which is within, but at

the lower end, of the range estimated in Adams and Jaffe (1996) for plant level R&D

effects.10

The elasticity of the private R&D stock is higher – a common finding in R&D

spillover studies- at 0.058, while spillover effects decay in distance, as the significant

distance parameter suggests. The estimates on the past TFP level suggest that plants that are 1

percent more productive than the average TFP level in the industry have a 0.08 percent point

9 Without approximation we would need to sum up over all R&D conducting firm-pairs and

industries for each plant to arrive at an update of the distance parameter , which is

computationally infeasible. We therefore approximate the distance function by taking a H-order

Taylor ’s expansion:

, such that the expression for the plant level

technologically proximate R&D stock becomes:

The summation over f ’ and s’ no longer depends on the distance decay parameter , and

summation over H suffices. We set H conservatively at 50 and at 1500 km (the midpoint of the

smallest and largest possible distance). 10 We note that their specification was cross sectional, and one may expect smaller effects in a differenced

model.

16

smaller TFP growth rate, indicating that there is a modest gradual convergence in

productivity. TFP growth of the plants is strongly influenced by opportunities and shocks

captured by the average TFP growth in the industry, with an estimated elasticity of 0.89. Of

the plant and firm control variables, only (growth in) the number of plants operated by the

parent firm has a marginally significant positive effect on TFP.

Insert Table 4

In model 2 we add the dummy variable indicating continuous positive R&D. Both the

dummy variable indicating positive R&D and the R&D stock are significant. The dummy

variable suggests that R&D performing firms generate on average 0.5 percent points higher

TFP growth (independent of variation in their R&D stocks). At the same time, the coefficient

of the parent R&D stock declines to about 0.01. Model 3 adds the technologically proximate

public R&D stock. The coefficient on public R&D, at 0.077 is larger than the coefficient on

technologically proximate private R&D, demonstrating the importance of knowledge

spillovers from public R&D. The estimates however do not suggest a significant geographic

decay effect of public R&D spillovers. The addition of public R&D in model 3 does not

materially affect the estimated coefficient on private R&D, which may indicate little overlap

in the type of knowledge from technologically proximate private and public R&D.

In model 4 the relationally proximate R&D stocks of customers and suppliers are added.

The relationally proximate R&D stock due to supplier linkages has a significant effect on

TFP growth with an elasticity of 0.031. The significant elasticity of customer R&D stocks is

slightly smaller at 0.026. Meanwhile, the coefficient on the technologically proximate R&D

stock reduces with the inclusion of the supplier and customer R&D stock variables, and at

0.035 is similar in magnitude as the elasticity of the supplier R&D stock. The estimated

distance decay for private R&D spillovers becomes smaller overall, suggesting weaker

proximity influences for relationally proximate R&D. Model 5 confirms this pattern: when

we allow separate decay parameters for the three private R&D stocks, the decay parameter

for technologically proximate R&D increases in strength whereas the model does not identify

a distance decay effects for R&D spillovers from buyers and suppliers. For technologically

proximate R&D spillovers, the decay function on the basis of model 5 is depicted in Figure 4.

Spillover effects decline and become negligible at about 500 kilometers. This pattern is

similar to the estimates reported in Lychagin et al. (2010) for US listed manufacturing firms

based on inventor locations.

Model 6 presents the results of an alternative model with one parameter estimated for the

(unweighted) sum of the three types of private R&D. The estimated coefficient for this

combined private R&D stock is close to 0.08 and larger than the estimated coefficient for

technologically proximate R&D in models 1-3. This underscores that failure to take into

account relational proximity may lead to an underestimation of R&D spillover effects. The

estimate of the distance parameter for the combined private R&D stock is close to the

parameter estimated in model 4.

Prior studies have suggested that firms need to invest in internal R&D in order to benefit

from academic research (e.g. Cassiman and Veugelers, 2006; Anselin et al., 1997; Belderbos

et al., 2009), as firms need the absorptive capacity to screen, understand, and utilize the fruits

of relevant scientific research (Cohen and Levinthal, 1990). In model 7, we separate the

effect of public R&D into an effect for firms without formal R&D expenditures and an effect

for firms with positive R&D. The results confirm that the presence of internal R&D increases

the magnitude of public R&D spillovers: the elasticity increases to 0.12, while the coefficient

for firms without internal R&D is only marginally significant (at 0.068). The difference

between the two coefficients is statistically significant.

Insert Figure 4

Sensitivity analysis

We further explored the role of distance for public spillovers and the assumption that

(private) R&D spillovers as a function of distance play out at the plant level. In an alternative

specification, we examine distance between the firms’ R&D laboratories and between R&D

laboratories and the location of public R&D institutions. In particular for public spillovers,

linkages may occur at the laboratory level and not necessarily at the plant level, while the

R&D laboratories may not necessarily be located close to the firms’ plants. We derived the

location of R&D laboratories from published directories of R&D establishments in Japan. For

R&D performing firms lacking laboratory location information, we assigned R&D to the

location of headquarters – the safest option for these -mostly smaller- firms (e.g. Adams and

Jaffe, 1996; Orlando, 2004). Our results, however, did not show geographic decay effects in

this specification either.

We conducted a number of additional sensitivity analyses, estimating model 6 on

different samples. First, we estimated productivity models for the entire population of

Japanese manufacturing plants (plants with TFP information; more than 230000 observations)

Page 19: Center for Economic Institutions Working Paper Seriescei.ier.hit-u.ac.jp/Japanese/pdf/wp_2013/wp2013-5.pdf · In addition to knowledge spillovers from technologically proximate R&D

18

to examine the robustness of our estimates. Here we treated the unmatched plants as zero

R&D plants while including a separate dummy variable indicating that the plants lack R&D

information. Second we estimated the model without smaller plants (leaving about 36000

observations) and on a balanced sample (limited to about 16000 observations), to explore the

implications of potential sample selection bias. All these models produced broadly similar

results, with some exceptions. The distance effect for technologically proximate R&D proved

difficult to identify in some of the models, while in two specifications only two of the

individual effects of supplier, customer, and technologically proximate R&D were

simultaneously estimated as significant. We aim to further explore the robustness of our

empirical model in future work.

Decomposition analysis

Given the time dimension in our data and the changes over time in R&D investments and

agglomeration, we can decompose long term TFP growth effects into several factors: firms’

internal R&D effects, private R&D spillover effects, and public R&D spillover effects. The

results of the decomposition analysis based on model 7 are presented in Figures 5-8. The

decomposition analysis is conducted for a balanced sample of close to 4200 plants. Keeping

the sample of spillover receiving plants stable ensures that the decomposition is not

influenced by period-on-period changes in the sample but highlights effects of the changing

‘supply’ of spillovers. The decomposition uses plants’ gross output as weights. Figure 5

shows that declining R&D spillovers, in particular private R&D spillovers, play an important

role in the decline in TFP growth over the years. The contribution of private R&D spillovers

to TFP growth for the plants in the balanced sample reduced from 0.896 percent points in

1987-1992 to 0.182 percent points in 2002-2007. The contribution of public R&D spillovers

also declined, but less so in relative and absolute terms. This is related to the more modest

decline in the growth in public R&D and a changing composition of public R&D

expenditures in the direction of life sciences with greater relevance for the private sector. The

role of internal R&D remained relatively stable, although this is to an important extent due to

the fact that R&D active firms record generally higher TFP growth than firms that are not

engaged in R&D.

We can further decompose the changing role of private R&D spillovers into the three

types of spillovers: spillovers due to technological proximity, buyer effects, and supplier

effects. Figure 6 shows that the technological proximity based spillovers and customer

spillovers have declined most, while the decline in supplier spillovers has been more modest.

Page 20: Center for Economic Institutions Working Paper Seriescei.ier.hit-u.ac.jp/Japanese/pdf/wp_2013/wp2013-5.pdf · In addition to knowledge spillovers from technologically proximate R&D

19

These divergent effects arise because the share of procurement from (R&D intensive) local

manufacturing industries has not decreased that much over time, while an increasing role of

exports has reduced relational proximity to Japanese customer industries.

Figure 7 decomposes private spillovers into effects due to the exit of R&D active plants,

the entry of such plants, and the changing R&D stocks of surviving plants. The exit of R&D

active plants reduces the R&D stock available to other plants and has a negative effect on

TPF growth. However, if the parent firm operates multiple plants, the exit of one of its plants

implies that another plant of the firm takes its place as ‘minimum distance’ plant providing

R&D spillovers, such that there is a compensating ‘plant substitution effect’. In such cases,

net spillovers decline only to the extent that the exit increases average distance between

plants. Similarly, if a firm opens up a new plant, this may increase the R&D stock available

to plants in its proximity, but at the same time it displaces the R&D stock of the firm’s plant

that was previously located at minimum distance to these receiving plants. Hence, in case of

entry there is a partially compensating negative substitution effect. This decomposition

exercise shows that while the largest part of the decline in spillovers is due to a slowing down

of R&D stock growth in surviving plants, increasing exit effects and reduced entry effects

over time also play an important role. Figure 8 shows that most of the exits have taken place

in the major industrial agglomerations in Japan around Tokyo and Kanagawa, Osaka, and

Aichi (home of a large automobile cluster) during 1997-2007

4. Conclusions

This paper examined the effects of R&D spillovers on total factor productivity in a large

panel of Japanese manufacturing plants matched with R&D survey data. We simultaneously

analyse the role of public (universities and research institutes) and private R&D spillovers,

while examining effects due to ‘relational’ (supplier-customer) proximity as well as

technological and geographic proximity. Our analysis confirms the importance of positive

spillover effects from R&D by firms with plants in technologically related industries. The

latter spillover effects are attenuated by distance and our estimates suggest that most spillover

effects disappear beyond 500 kilometres. We also observe positive effects of public R&D

spillovers, with the effects substantially larger for plants with access to internal R&D. We do

not find evidence that public R&D spillover effects are attenuated by distance. In addition to

knowledge spillovers from technologically proximate plants, we find evidence that ‘relational

proximity’ due to buyer and supplier linkages generates additional ‘pecuniary’ R&D

spillovers of similar magnitude as the knowledge spillovers due to technological proximity.

We could not identify the role of geographic distance in these buyer and supplier spillovers.

We conclude that public as well as private R&D spillovers matter for TFP growth, while

relational proximity as well as technological proximity needs to be taken into account to

arrive at representative estimates of the social effects of private R&D. Decomposition

analysis shows that the contribution of private R&D spillovers to TFP growth has declined

since the late 1990s. This is due to a declining growth in R&D stocks while another important

factor is the exit of proximate plants operated by R&D intensive firms. A mildly declining

contribution of public R&D spillovers is primarily due to a reduction in the growth of R&D

by public research organization since the late 1990s. If we explore effects at the regional level,

we observe that strong adverse exit effects occurred in particular in Japan’s major industrial

agglomerations such as Tokyo and Osaka.

Our results help to explain the twin stylized facts of Japanese productivity growth: the

exit of relatively productive plants and the declining TFP growth or surviving plants (Fukao

and Kwon, 2006; Kneller et al., 2012). They suggest that these two trends may be causally

related. The exit of plants by R&D intensive firms reduces the available R&D spillovers and

hampers TPF growth of the surviving plants.

In future work, we aim to get a better understanding of the (absence of) distance effects

in R&D spillovers. One reason for the lack of estimated distance effects for public R&D may

be that public R&D spillovers occur most often through active collaboration across larger

distances (Okamuro and Nishimura, 2013; Gittelman, 2007). We can explore these

explanations by incorporating information available on research relationships between firms

and universities. Second, we aim to investigate the role of proximity effects in buyer-supplier

relationships in more detail by utilizing data on the most important buyers and suppliers of

individual Japanese firms. Third, we are planning to match the data with the Basic Surveys on

Business Activities in Japan, which contain information on corporate relationships and

foreign activities. Matching with the Basic Surveys allows bringing in controls on overseas

R&D conducted/outsourced by the firms and the potentially resulting international transfers

and knowledge spillovers (e.g. Branstetter, 2001; Griffith et al., 2008). It also allows analysis

of potentially greater R&D spillovers for firms operating within business groups (Suzuki,

1993; Branstetter, 2000). Collectively, the remaining challenges for exploration of R&D

spillover effects present a rich research agenda.
