ABSTRACT

We use Office for National Statistics' micro data for large UK establishments in the production industries in the period 1997–2008 to study the relationship between their productivity and the presence of substantial R&D activities, either at the production unit itself, or at other UK reporting units owned by the same enterprise group. We estimate that total factor (revenue) productivity is on average about 14% higher at the establishments which have substantial R&D themselves, compared to those with no R&D. Among the establishments with no R&D themselves, we estimate that productivity is on average about 9% higher at those which belong to enterprise groups which do have substantial R&D elsewhere in the UK in the same sub-sector. For the establishments with substantial R&D themselves, we also estimate a significant positive relationship between current productivity and past R&D expenditure using dynamic specifications which allow for both establishment-specific ‘fixed effects’ and a serially correlated error component.  相似文献

The research and development (R&D) system for industrial development in Taiwan is made up of three parts: industrial firms, government-supported institutes (GSIs), and academic institutes and universities. The Taiwanese experience showed that the effective interaction of the GSIs and the industrial firms has successfully supported the development of its industry. The Industrial Technology Research Institute (ITRI) played the key role in industrial development during recent decades. This study provides a comprehensive analysis of ITRI and the way in which it fulfills its role through an examination of its major tasks. The implications for developing countries are also discussed.  相似文献

We examine the impacts of both domestic and international financial market development on R&D intensities in 22 manufacturing industries in 18 OECD countries for the period 1990–2003. We take account of such industry characteristics as the need for external financing and the amount of tangible assets. Multiple forms of domestic financial development are important determinants of R&D intensity but only foreign direct investment is significant among alternative measures of international financial development. We find the strongest effects for private bond-market capitalization, while FDI, private credit by banks, and stock-market capitalization have similar effects in terms of magnitude.  相似文献

A model is developed of the relation between adoption of an innovation by firms and firm size. Decision making is represented as a group assessment of the perceived ratio between expected returns after succesful introduction, and the risk that implementation will fail or will last too long to makc adoption worth while. In view of differences in thc assessment of uncertainty and corresponding demands on the perceived return-to-risk ratio, among influencers of decisions in the firm, decision making is taken as stochastic, with a probability of adoption related to (objective) net benefits, and probability of non-adoption related to risk. The model gives a new way of looking at the fact that small firms lag behind in the adoption of new technology. In contrast with previous models proposed by David and Davies the explanation has nothing to do with there being some critical size below which adoption is not profitable. The present model explains the adoption lag for smaller firms as the result of expected returns being proportional to size while risk of failed implementation is independent of size. The model is tested and estimated empirically on data for the adoption of computers in small scale retailing, in the Netherlands.  相似文献

The impact of public R&D expenditure on business R&D*   总被引:1,自引:0,他引:1  

This paper attempts to quantify the aggregate net effect of government funding on business R&D in 17 OECD Member countries over the past two decades. Grants, procurement, tax incentives and direct performance of research (in public laboratories or universities) are the major policy tools in the field. The major results of the study are the following: Direct government funding of R&D performed by firms has a positive effect on business financed R&D (except if the funding is targeted towards defence activities). Tax incentives have an immediate and positive effect on business-financed R&D; Direct funding as well as tax incentives are more effective when they are stable over time: firms do not invest in additional R&D if they are uncertain of the durability of the government support; Direct government funding and R&D tax incentives are substitutes: increased intensity of one reduces the effect of the other on business R&D; The stimulating effect of government funding varies with respect to its generosity: it increases up to a certain threshold (about 10% of business R&D) and then decreases beyond; Defence research performed in public laboratories and universities crowds out private R&D; Civilian public research is neutral for business R&D. * We thank the participants to various seminars, including the OECD Committee for Scientific and Technology Policy and the NBER 2000 Summer Institute on Productivity for helpful comments and suggestions. All opinions expressed in this article are those of the authors and do not reflect necessarily the views of the OECD or Université Libre de Bruxelles.  相似文献

This study analyzes the effect of strengthening patent protection for innovation and economic growth by introducing a blocking patent into the endogenous growth model developed by Furukawa (Econ Lett 121(1):26–29, 2013a), which features survival activity of patent holders in the R&D sector with a variety-expansion model. Results show that strengthening patent protection can raise the economic growth rate and social welfare through an endogenous survival investment. Additionally, this study examines the effects of increasing subsidies for R&D. We find that increasing R&D subsidy rate can negatively affect economic growth and social welfare because of the investment for survival activities. This result shows the novel role of a blocking patent in determining innovation effects of R&D subsidies. Furthermore, we analyze the effect of patent breadth which is another patent instrument in this model on innovation and economic growth. Results show that the growth and welfare effects of the profit-division rule and the subsidy rate for R&D may vary with the size of patent breadth.  相似文献

Although firms have many reasons for investing in R&D, still market forces are believed to be inadequate for directing an optimal amount of funds towards R&D investments. An important tool for diminishing this failure on markets for R&D is to sustain R&D co-operatives, a policy instrument recently (re)discovered by public authorities. For quite some time the formal economics literature did not pay substantial attention to this policy, but with the appearance of the seminal analysis of d’Aspremont & Jacquemin (1988) this silence was abruptly disturbed.The objective of the present paper is to develop a general version of the d’Aspremont & Jacquemin (1988) model which still allows for the calculation of explicit equilibria and therefore enables a comparison between co-operative and non-co-operative R&D. While pursuing this objective an analysis is presented which encompasses several recent contributions to the literature.Having established this general characterization of a market with possible strategic R&D co-operatives the arguments against and in favour of this industrial policy are evaluated. It appears that there are circumstances when these strategic alliances could indeed be socially beneficial. However there remains always the threat of firms increasing their market power by extending the co-operative agreement to the product market.  相似文献

Policy makers encourage integrating Social and Ethical Aspects (SEAs) in Research and Development (R&D) for the responsible development and deployment of future and emerging technologies, including Nanotechnology and Life Sciences. However, R&D project leaders in industry generally do not integrate SEAs explicitly in their daily practice. Furthermore, to what extent SEAs improve R&D remains unclear. We carried out a comparative research case study to assess to what extent R&D projects can be measurably improved through the integration of SEAs.We combined recent insights from Science and Technology Studies and Innovation Management to integrate SEAs in industrial R&D in the field of food technology and measured changes in project performance based on Key Performance Indicator (KPI) scores. We used Midstream Modulation with a group of project leaders and measured their projects' performance using a modified version of the Wageningen Innovation Assessment Toolkit.Results show that the integration of SEAs was not only perceived by participants to be functional and useful, but it also measurably improved KPI scores. We propose that the two methods can be integrated into a Success Factor based Live Innovation Project Scoring and Evaluation tool, which can be functionally deployed in R&D environments.  相似文献

This paper explores the R&D cooperation determinants of the innovative companies belonging to the Spanish manufacturing sector. Our findings suggest that the variable R&D subsidy is endogenous, significant, and has a strong positive influence on R&D cooperation. This is a clear indication that the achievement of public aid is often conditioned by the obligation for companies to cooperate in R&D. We have also found that the differentiation strategy variable is significant and has a negative influence on R&D cooperation. Companies positioned in a differentiation strategy probably own and use some different knowledge from other companies. Consequently, they will not have much interest in taking advantage of the spillovers generated by other companies. It is therefore logical that they are reluctant to establish cooperation agreements on R&D. Therefore, companies positioned in the differentiation strategy need public policies to support R&D that are not conditioned to the establishment of cooperation agreements.  相似文献

This paper uses a comprehensive firm level data set for the manufacturing sector in Italy to investigate the effect of government support on privately financed R&D expenditure. Estimates from a non‐parametric matching procedure suggest that public assistance has a positive effect on private R&D investment in the sense that the recipient firms achieve more private R&D than they would have without public support. This indicates that the possibility of perfect crowding out between private and public funds can be rejected. Furthermore, in this sample of Italian firms, tax incentives appear to be more effective than direct grants. The paper also examines whether public funding affects the financial sources available for R&D and finds that grants encourage the use of internal sources. The results also show some evidence of positive effects on credit financing for R&D.  相似文献

ABSTRACT

R&D investment are an important engine of growth and development. Yet economists have often claimed underinvestment, based on the consideration that these projects are more costly to finance, especially, due to the asymmetric information between inside and outside investors. Coherently, a recent empirical evidence has shown that firms intensively active in R&D are less leveraged and rely more heavily on internal finance. Motivated by this evidence, we study the effects of asymmetric information and financial frictions within a GE economy of Schumpeterian tradition. The model and equilibrium concept are rich enough to represent investment and innovation decisions, technology adoption/diffusion through patent licensing and, most importantly, firms' financial decisions. In this representation, R&D-intensive firms might effectively rely more on internal sources and equity than on debt financing, relative to what would happen in frictionless markets. Further, financial decisions affect aggregate investment and income dynamics.  相似文献

This paper introduces defection into the strategic R&D model. In defecting, a firm cheats by choosing its R&D expenditures to maximise its own profits, instead of maximising the joint profits of the cooperating firms. Two cooperative environments are considered: R&D cartelisation, where firms coordinate R&D activities; and RJV cartelisation, where firms coordinate R&D activities and share information. Under R&D cartelisation, defection entails an increase (decrease) in R&D and effective spillovers for low (high) spillovers; whereas under RJV cartelisation, defection always entails a decrease in R&D and effective spillovers. Under R&D cartelisation, consumer surplus and total welfare increase (decrease) with defection when spillovers are low (high). Whereas consumer surplus and welfare always decrease with defection under RJV cartelisation. Under R&D cartelisation, the incentives for defection first decrease then increase with spillovers; they also increase with the size of the market, but decline with production costs and R&D costs. Moreover, the incentives for defection are higher under RJV cartelisation. With low spillovers under RJV cartelisation, a firm prefers to be subject to defection by the other firm, to not cooperating at all. Punishment for defection is considered, under the form of abstaining from information sharing.  相似文献

Endogenous protection of R&D investments   总被引:1,自引:0,他引:1  
Abstract .  We examine firms' incentives to protect their non-cooperative R&D investments from spilling over to competitors. We show that, contrary to findings in most of the literature, the lack of full appropriability can lead to an increase in R&D investments. Consequently, as long as the R&D spillovers are not too strong, firms decide to let their R&D knowledge flow. Since, as we show, welfare is higher when R&D spillovers are present, it follows that public policies that promote the dissemination of technological knowledge could be welfare-enhancing.  相似文献

This paper investigates the R&D persistence of R&D active firms in different markets with different intensities of competition, based on firm-level panel data for the period 1996–2008. In a dynamic setting of the empirical model, it turns out that persistence is strongly related to market competition (measured by the number of principal competitors). Persistence of R&D expenditures is more likely to be observed in markets with few principal competitors (between six and 10) and is very unlikely to be observed in polypolistic market types (more than 50 competitors).  相似文献

This paper studies the firm’s decisions on in-house R&D and its procurement from outside through commissioned R&D, joint R&D, and technology acquisitions (i.e., licensing-in). Using the data about 14,000 manufacturing firms in Japan, we estimate a modified double-hurdle model in which the first hurdle determines whether the firm should perform any R&D at all and the second hurdle determines whether (and how much) it should perform each mode of procured R&D. The results generally support the two major theories—the transaction cost theory and the capability theory. The estimated positive effects of firm size, in-house R&D intensity, diversification, and vertical integration support the hypothesis that capability is needed for procured R&D, while the estimated positive effect of the index of appropriability by patents supports the hypothesis that this appropriability reduces transaction costs. In addition, we found that information flow from scientific sources and that from transaction-based sources affect the three modes of procured R&D differently.  相似文献

Abstract

We have investigated non-cooperative and jointly optimal R&D policies in the framework of Spencer & Brander (1983) in the presence of R&D spillovers. When R&D activities are strategic substitutes and the R&D game exhibits a positive externality, the result of Spencer & Brander (1983) reverses: the non-cooperative policy is a tax while the jointly optimal policy is a subsidy. Moreover, when R&D activities are strategic complements, the usual result of the prisoners' dilemma in the strategic subsidy game does not hold, implying that a welfare intervention is preferable over laissez-faire. When spillovers are sufficiently large, the joint welfare increases with subsidies being higher than those under non-cooperation.  相似文献

In this paper, the effectiveness of R&D subsidies is analyzed in an oligopolistic model that we apply to the cases of international R&D competition and cooperation. We find that the existence of asymmetric information among firms on whether a rival (or partner) is being subsidized or not may play a key role in explaining whether subsidies are effective or not in increasing R&D investments. In particular, it is shown that if the existence of the subsidy is made public (e.g. because strict information release regulation about R&D subsidies is enforced) and depending on the strategic relationship between the firms’ R&D efforts, an R&D subsidy could even hurt the subsidized firm.  相似文献

This paper investigates how internal and external factors affect the choice between alliances and joint ventures (A&;JVs) and mergers and acquisitions (M&;As) for the external sourcing of research and development (R&;D) activities, and whether or not such a choice is really contingent, that is, is it the best choice in terms of its impact on firms' innovative performance under those circumstances? We build a set of hypotheses based on both the transaction-cost theory and the resource-based view, and test them through a secondary data source analysis. We found that companies adopt either R&;D M&;A or A&;JV depending on internal (e.g. resources and capabilities, innovation experience) and external (e.g. degree of industry specialisation) factors. Surprisingly, this contingent choice turns to be effective on innovative performance only for the internal factors, rather than the external. This paper contributes to inter-firm relationships literature by presenting the real advantages of using integrated and contingency theoretical models to understand contingent decisions.  相似文献
