Through an industry-level analysis of Chinese large- and medium-size manufacturing enterprises over the period of 1996-2001, this article investigates the direct and interactive contributions of four technology acquisition channels to industry performances in terms of innovation performance and productivity. These channels include in-house R&D, foreign technology transfer, domestic technology transfer, and inter-industry R&D spillover. We have found evidence of an important role of inter-industry R&D spillover in shaping and improving industry performance in China, which has been neglected by previous empirical studies concerned with Chinese industrial firms. The empirical results indicate that inter-industry R&D spillover and foreign technology transfer make significant contributions to both labour productivity and the level of total factor productivity in Chinese manufacturing industries. We have also found that in-house R&D and inter-industry R&D spillover share a complementary relationship in shaping innovation performance and total factor productivity in Chinese industry, and that in-house R&D relates to foreign technology transfer as a complement for labour productivity. Finally, on the mixed results among existing literature in the context of developing countries, this article argues that the commonly followed strategy in technology development, combined with government regulations, will play an essential role in determining the relationship between in-house R&D and foreign technology transfer.  相似文献

This paper investigates the effects of interindustry R&D spillovers from publicly financed business R&D on private R&D efforts and productivity using data of West German manufacturing industries. The results suggest that it is important to distinguish between the effects of spillovers from privately and publicly financed business R&D. In particular, estimation results provide evidence of productivity-enhancing effects of spillovers from privately financed R&D while results are less clear-cut for publicly financed R&D. Moreover, there is some empirical evidence that private R&D efforts of higher-technology industries are stimulated by spillovers from privately financed R&D but not by spillovers from publicly financed R&D. However, public funding of R&D in higher-technology industries seems to induce private R&D investments within these industries.  相似文献

The R&D effort, even of the largest, most technologically advanced developing countries, and their most sophisticated firms, cannot match that of the major industrial nations or the largest corporations. Our objective in this paper is to analyse innovation, technical change and R&D management in technology-leaders to build a framework for R&D in technology-followers outside of those major nations. This framework emphasises the importance of specific learning mechanisms and puts forward an argument that in-house R&D is indeed required in technology-followers, but a profoundly different type of R&D. R&D units, based in the firm, can become the location for organised learning, the problem-solver of last resort in production, the in-house knowledge store and gatekeeper, and the focus for independent design and product development capacity.  相似文献

The US Department of Defense funds a significant fraction of the in-house R&D of its defense contractors through its Independent Research and Development (IR&D) program. These IR&D funds, however, are reported as company-financed R&D in statistics compiled by the National Science Foundation. The program is most important in the aircraft industry, where we estimate that IR&D payments were 20% of the R&D reported as company-financed in 1973. Because special regulations govern the IR&D program, it would be more appropriate for most purposes to treat IR&D as part of federally-financed, not company-financed, R&D.  相似文献

This article examines some of the key features of Japanese evaluation systems utilized in evaluating R&D policies. The distinctive features of the system are that Japan depends upon in-house self-assessment combined with close cooperation and consensus-seeking behavior with the government and its advisory bodies. This system is markedly different from those predominant in countries where R&D policies are evaluated separately, independent from the sphere of decision-making. The system described here is subjective rather than objective in that the direct promoters of R&D plans were directly included in the evaluation activities. The system has evolved gradually in the course of Japanese technological development, and has been influenced also by Japan's particular internal and external environment. The system appears to have worked well in areas where research programs were modified to obtain incremental improvement or to create new types of R&D programs. However, recent constraints caused by budget deficits, together with the shift from applied to more basic research, have required a new type of evaluation system for Japan's R&D policy.  相似文献

Electricity sector liberalisation has coincided with a significant decline in R&D spending. This paper reviews the industrial organisation literature on R&D and innovation to explore the likely causes of the decline in R&D spending in the electricity sector. Meanwhile, R&D productivity and innovative outputs in utilities and equipment suppliers appear to have improved. However, a lasting decline in R&D expenditure can have a negative long-term effect on technological progress and innovation in the sector. We conclude that the decline in R&D could have been predicted from the literature. We also discuss the need to reorient the post-liberalisation technology policy.  相似文献

The various strands of extant empirical research are inconclusive about the complementarity or substitutability between different innovation mechanisms, such as internal and external R&D. Using a panel sample of 83 incumbent pharmaceutical firms covering the period 1986-2000, our empirical analysis suggests that, instead of a clear-cut answer to the question of whether internal and external R&D are complementary or substitutive innovation activities, there appears to be a contingent relationship between internal and external R&D strategies in shaping a firm's innovative output. The results from our study indicate that the level of in-house R&D investments, which is characterized by decreasing marginal returns, is a contingency variable that critically influences the association between internal and external R&D strategies. In particular, internal R&D and external R&D, through either R&D alliances or R&D acquisitions, are complementary innovation activities at higher levels of in-house R&D investments, whereas at lower levels of in-house R&D efforts, internal and external R&D turn out to be substitutive strategic options.  相似文献

This paper investigates the causal effect of foreign acquisitions on the research and development (R&D) activities of domestic target firms over the period 1994–2004. Using accounting data on French innovative manufacturing firms, we implement appropriate difference-in-difference estimation techniques associated with a matching propensity score procedure. We find that the acquisitions of French firms by foreign companies boost R&D spending. There is a simultaneous rise in the external and in-house R&D expenditures of French acquired firms. R&D is more contracted out to local research providers, in particular to local public laboratories and universities. The increase in internal R&D spending benefits to development, but also basic and applied research. Finally, the growth of the R&D budget is not only financed by internal resources but also receives financing from external partners, especially parent companies. Thus, our results call into question the idea that foreign takeovers hamper the R&D development of target firms and are detrimental to the national innovation system of the host country. First, acquisitions appear to bring efficiency gains enough to counterbalance the various costs of integration and market power effects, pushing firms to invest more in R&D. Acquisitions do not seem to incite managers to take shorter term and more financial driven decisions at the expense of R&D. Second, when motivated by technology sourcing and overseas R&D development, acquisitions might be used to access the specific know-how of target firms and to tap into the knowledge of the national innovation system. Then, purchaser firms could be more likely to develop the innovative capability of target firms and to strengthen their linkages with local partners than to reduce them and relocate R&D abroad.  相似文献

This paper surveys the trends in industrial R&D in India over the last two decades. It shows that there has been a rapid rise in R&D expenditure and a shift in its composition towards in-house corporate R&D and away from R&D in government laboratories, which is explained by the laboratories' lack of market orientation and manufacturing experience. According to cross-section studies of corporate R&D, larger companies aim towards larger technological advances and take a longer view; but the overall composition of corporate R&D shows no discernible change. This apparent inconsistency is explained by the development of the technology market. Much R&D was triggered off by the need for import replacement arising from import controls till 1965 and later by the need for product diversification in the recession. But construction of new plants and mechanization for speeding up operations, activities where sustained R&D can yield large firms a steady flow of innovations, were unimportant or infrequent, and the demand for technology they gave rise to was largely met by imports.  相似文献

Many regions of the European Union with a high degree of autonomy have elected very clearly to stimulate scientific research and technological development (R&D) as a specific means of promoting economic growth and the welfare of their citizens. In Spain, several autonomous regions have organised their efforts in science and technology by means of the adoption of regional R&D plans. In some cases, particular concern is taken to link the scope of scientific research with that of technology, but even in these few cases, it is acknowledged that little is known of the mechanisms by which the results of scientific research are translated into technological development, and how this latter in turn influences the objectives of scientific research. Our aim in this article is to study in greater depth the relationship between science and technological development in the various regions of Spain. The methodology that we apply to investigate the links between science and technology is based on an analysis of scientific citations in patent documents (non-patent citation (NPC)). The results obtained from this study provide some relevant data on the interconnection between the scientific and technological systems from a regional perspective.  相似文献

This paper is a first step toward closing the analytical gap in the extensive literature on the results of interactions between public and private R&D expenditures, and their joint effects on the economy. A survey focusing on econometric studies in this area reveals a plethora of sometimes confusing and frequently contradictory estimates of the response of company-financed R&D to changes in the level and nature of this category of public expenditures. Yet, a theoretical framework seldom is provided within which the empirical results are to be interpreted. Some such structure is necessary, in view of the multiple channels through which public research can affect private R&D performance, especially as not all the effects flow in the same direction. A major cause of “inconsistencies” in the empirical literature is the failure to recognize key differences among the various policy “experiments” being considered — depending upon the economy in which they are embedded, and the type of public sector R&D spending that is contemplated. Using a simple, stylized structural model, we identify the main channels of impact of public R&D. We thus can characterize the various effects, distinguishing between short- and long-run impacts that would show up in simple regression analyses of nominal public and private R&D expenditure variables. Within the context of our simple model it is possible to offer interpretations that shed light on recent cross-section and panel data findings at both high (i.e., national) and low (specific technology area) levels of aggregation.  相似文献

This paper examines the relationship between the economic growth of European regions and their knowledge and human capital endowments. The share of adult population with tertiary education and the intensity of R&D expenditures in value-added emerge as the most effective factors enhancing the growth of GDP per capita recorded, during 1995–2002, by the regions belonging to twelve countries of the former EU15. However, while the educational variable is effective for the whole regional set, the impact of R&D is significant only for the regions that are above a given threshold of per capita GDP. Moreover, remarkable disparities arise among the regions of different countries. In particular, only within North European countries there is a significant relationship between regional growth and the intensity of R&D and higher education. The policy implications of both findings are discussed.  相似文献

This paper reviews the literature on the location and regional effects of science and technology (S&T) in the context of developed economies. Two processes associated with the creation of new products, agglomeration and spin-off, act to attract further innovative activity in those regions. Other regions, where R&D and related activities do not take place, are unlikely to be the locations of new-product production, and instead will tend to specialize in the production of standardized products. Both corporate and government R&D rely on pools of technical labor for technological and new-product activities; these pools of mobile workers are most attracted to large urban areas. In only some of these areas, however, does the spin-off process result in the generation of new technology-based firms. The availability of local venture capital appears to be the principal influence on this variation. Government policy regarding science and technology has impacts on regions by contributing to the agglomeration of R&D. Government policy also often fails to recognize that S&T policy and industrial policy have regional effects that may be long-term in nature and most detrimental to those regions whose economies are least competitive. Finally, some priorities for future research on innovation in a regional setting are identified.  相似文献

This paper investigates the role of government R&D subsidy programs in stimulating knowledge spillovers. R&D subsidies are an effective public policy instrument when knowledge spillovers exist yet ex ante it is difficult to identify projects that have the greatest potential to increase innovation and economic growth. This paper derives a set of project and firm attributes that the literature finds generate knowledge spillovers and uses data on project proposals to estimate the degree to which a government R&D program conforms. We find that projects that were awarded R&D subsidies were more likely to have attributes such as participation in new research joint ventures and connections to universities and other firms. Following the post-award activities of firm, we find that receipt of a government R&D subsidy increased the funding from other sources when compared to firms that were not awarded funding.  相似文献

Motivated by recent statistics that show significant growth in labor productivity, this paper seeks to analyze the long-term relationship between domestic R&D, knowledge stock and productivity dynamics. Time series data of the German manufacturing industry is used to estimate a variable cost function with the stock of knowledge being dependent upon current and past R&D spending. The estimates indicate that 50% of the effects of R&D on the knowledge stock appear within 4 years. However, the rate of return on R&D are shown to be drastically declining; recent rates of return on R&D are estimated to have reached an all-time low spanning the last 45 years. Current yields of R&D are only one third compared to the sixties. In conclusion, though the productivity slowdown of the seventies seems to have been overcome, this is not attributed to R&D investments.  相似文献

Using original survey data on Japanese small businesses, this paper analyses the impact of the organizational and contractual characteristics of cooperative R&D, such as membership structure, partner relationship, external support, and rules of cost and outcome sharing, on the probability of the technological and commercial success of the project. Empirical results suggest that cooperative R&D is more successful, the higher the quality and quantity of external resources available through cooperation, and the lower the transaction and coordination costs required for such arrangements. Moreover, we found that the determinants of technological and commercial success differ considerably.  相似文献

This paper examines the hypothesis that economic internationalisation is acting to reduce the importance of national technology ‘gaps’ as determinants of trade patterns and performance. The cross-country analysis uses two approaches to assess the dynamic nature of the relationship between national investment in technological capability (proxied by both R&D activity and human capital) and technology-intensive (TI) trade performance. Natural resource endowment and the changing impact of physical capital formation are also investigated. The study includes approximately 48 nations and is based on data from the mid-1970s to 1990. The empirical evidence from one approach undertaken does not support the globalisation hypothesis as national investment in technology and human capital is shown to have maintained its link to international trade success in TI manufactures over the study period. However, the findings of the alternative approach are ambiguous. A positive association between technology investment catch-up and ongoing TI manufacturing trade performance is evident for the newly industrialised economies (NICs), but the results suggest that an inverse relationship may apply for many of the ‘mature’ Western economies.  相似文献

National surveys of R&D labs across the manufacturing sectors in the US and Japan show that intraindustry R&D knowledge flows and spillovers are greater in Japan than in the US and the appropriability of rents due to innovation less. Patents in particular are observed to play a more central role in diffusing information across rivals in Japan, and appear to be a key reason for greater intraindustry R&D spillovers there, suggesting that patent policy can importantly affect information flows. Uses of patents differ between the two nations, with strategic uses of patents, particularly for negotiations, being more common in Japan.  相似文献
