This paper presents a data envelopment analysis (DEA)/Malmquist index methodology for measuring the change in R&D efficiency at both firm and industry levels. Letting each of ten firms in each year be a separate decision-making unit, and employing one input and three outputs in a DEA case of R&D activity input-output lag, we measure “total factor R&D efficiency” change of Japanese pharmaceutical firms for decade 1983-1992 as defined by the period of R&D input. Decomposing Malmquist index into catch-up and frontier shift components and using “cumulative indices” proposed in this study, we evaluate R&D efficiency change for each firm and empirically show that R&D efficiency of Japanese pharmaceutical industry has almost monotonically gotten worse throughout the study decade.  相似文献

We examined 79 Japanese MNCs’ R&D subsidiaries in the US from the knowledge-based view. We found: (1) subsidiaries’ R&D strategies generally encouraged knowledge flows; (2) subsidiaries’ R&D alliances promoted knowledge flows; (3) R&D subsidiaries with process-oriented incentives promoted vertical knowledge flows; (3) autonomous R&D subsidiaries promoted knowledge flows from the local environments to the subsidiary; (4) R&D subsidiaries with a high level of knowledge flows accumulated a high level of knowledge; and (5) R&D subsidiaries with a high level of accumulated knowledge achieved high overall performance. Our interviews with 30 R&D subsidiaries and 10 parent companies supplement these findings.  相似文献

Japan has established several R&D programmes since the 1980s aimed at basic and fundamental R&D in response to the criticism of its free-riding on Western basic research. In some of these programmes, the linkages between university, industry and government have been a requirement for formation or selection of projects. In this paper, it is investigated how five Japanese R&D programmes promote inter-sectoral and inter-institutional networks. The result shows that the projects of the Next Generation Programme for pre-competitive research formed few but multiple university-industry-government linkages within each project by designing the complementary relationships among the participants. Linkages between private companies were not much formed except for the projects of the ERATO Programme, in which researchers temporarily leave their own institutes. The funds for more basic research was found to have little effect on the formation of networks within projects but do form the linkages outside the projects.  相似文献

The purpose of this paper is to critically examine the institutionalization of demand-driven modes of working in the R&D planning process and reveal possible weaknesses, through an analysis of a system of collective R&D funding by farmers. The findings indicate that, although end-users have the opportunity to raise issues that lead to R&D, queries are influenced by several actors in the R&D planning process in such a way that they do not adequately reflect farmers’ innovation needs. Conclusions are that more emphasis is required on joint demand articulation and involvement of end-users and other stakeholders in the innovation process, and on the institutional development of R&D funding organizations in order to adopt a more inclusive view on innovation.  相似文献

There have been many previous studies exploring the relationship between R&D performance and firm size; however, to our knowledge, this issue has never been examined in terms of R&D output elasticity. This paper therefore sets out to re-examine the relationship of the two variables using R&D output elasticity as a measure of R&D performance. A total of 126 manufacturing firms, listed on the Taiwan Stock Exchange over the period from 1994 to 2000, are taken as the analytical sample. One practical consideration for choosing these particular firms is the relative abundance of data available for the variables for a longitudinal investigation. The estimates suggest that there is an approximating ‘U-type’ relationship between R&D productivity and firm size. This finding suggests that both large and small firms have higher R&D productivity, and even when the sample is divided into the high-tech and traditional sectors, such a finding still holds. Therefore, in contrast to the prior studies, this study shows that size offers advantage in R&D performance.  相似文献

This paper analyses the freeriding behaviour in the case of public finance for R&D activities in enterprises. It will start with a brief discussion about the concept of freeriding and its importance to justify public support measures and offers a review of the methods, indicators and results reflected in the evaluation studies.In the second part of the paper, the impact of the Spanish low interest credits for R&D projects for individual firms will be analysed. A profile of the “freerider firms” will be offered, defined as those supported firms whose innovative efforts do not depend on public aid and probably would or could have carried out the same level of innovative activities without public support. Moreover, the paper presents some evidence that firms with a freerider behaviour show a lower level of goal achievement related to their technical and commercial objectives and consider the learning effects as less important than the other firms. This could suggest, indirectly, that freeriders generate fewer externalities available for the production system as a whole—than the non-freerider firms.  相似文献

Innovation and R&D spillover effects in Spanish regions: A spatial approach   总被引:1,自引:0,他引:1  
This paper analyses the spatial patterns of innovation, its regional interdependencies and evolution, as well as its role in determining local innovation in Spanish regions. Results indicate the suitability of a trade-based regional proximity when considering spatial spillovers in innovation. In this context, not only local capacity is relevant in determining domestic innovation, but also spatial innovation spillovers, which result mainly from efforts in both higher education and public administration. Moreover, a minimum level of regional development is required to improve the effectiveness of R&D policies. Therefore, it is necessary for R&D policies to act in combination with other policies focused on the improvement of socio-economic and structural determinants of regional innovative performance.  相似文献

Regional investment in R&D, technological development and innovation is perceived as being strongly associated with productivity, growth and sustained international competitiveness. One policy instrument by which policy makers have attempted to create regional advantage has been the establishment of publicly funded research centres (PRCs). In this paper we develop a logic model for this type of regional intervention and examine the outputs and longer-term outcomes from a group of (18) publicly funded R&D centres. Our results suggest some positive regional impacts but also identify significant differences in terms of innovation, additionality and sustainability between university-based and company-based PRCs. University-based PRCs have higher levels of short-term additionality, demonstrate higher levels of organisational innovation but prove less sustainable. Company-based PRCs demonstrate more partial additionality in the short-term but ultimately prove more sustainable.  相似文献

The dynamics of R&D network in the IT industry   总被引:1,自引:0,他引:1  
In this paper, we provide an empirical analysis of evolving networks of successful R&D collaborations in the IT industry (consisting of firms that obtained patents in the technological category of computers and communication) in the U.S. between 1985 and 1995. We first show that the R&D network has become more extensive, more clustered, and more unequal in the sense that ‘stars’ have emerged in the network. We then analyze the effect of the existing network structure in the process of new R&D collaboration formation. We control for unobserved similarities among firms based on the community structures within the network that the algorithm developed by Girvan and Newman (2004) identifies and find a significant cyclic closure and preferential-attachment effect.  相似文献

The use of R&D grants as a policy instrument has been motivated by economic arguments of market failure. Neo-classical econometric studies have analysed the additionality of one Euro of subsidies on both the investments of companies in the R&D process and the output of that R&D process. More recently, behavioural additionality has been launched as a third form of additionality. In contrast to input and output additionality, behavioural additionality is related to changes in the processes that take place within the firm. In this paper, we analyse the determinants of the behavioural additionality of R&D grants. To explain the mechanism through which behavioural additionality is obtained, we use organizational learning theory as a guide to formulate our hypotheses. Hypotheses are tested using a telephone survey of 192 recipients of R&D grants provided by the IWT in Flanders in 2001–2004, matched to a sample of 84 firms that undertake innovation activities but which had never had a grant bid accepted. We find that congenital learning and interorganizational learning lead to increased behavioural additionality. However, these learning effects decrease with the number of subsidized projects that are undertaken by the company.  相似文献

One of the benefits claimed for investment in Research and Development (R&D) is that there is a spillover effect. Industries benefit from both their own R&D efforts as well as the efforts of other national and overseas industries. The present research presents new evidence on the long-term impact of R&D investment upon UK industry's productivity performance and on the nature of these “R&D spillovers”. The results suggest that R&D efforts from the industry itself and from other national industries have a positive impact on the industry's productivity but, interestingly, there is no gain from foreign R&D investment.  相似文献

Relying on efficiency analysis, we evaluate to what extent policy makers have been able to promote the establishment of consolidated and comprehensive research groups to contribute to the implementation of a successful innovation system for the Spanish food technology sector, oriented to the production of knowledge based on an application model. Using data envelopment analysis techniques that allow calculation of a generalized version of the traditional distance function model for productive efficiency, we find pervasive levels of inefficiency and a typology of different research strategies. Among these, in contrast to what has been assumed, established groups do not play the pre-eminent benchmarking role; rather, partially oriented, specialized and “shooting star” groups are the most common patterns. These results correspond with an infant innovation system, where the fostering of higher levels of efficiency and the promotion of the desired research patterns are ongoing.  相似文献

We posit that the effects of R&D investment on financing choices depend on the degree of intervention barriers and appropriation discrepancy between capital providers and the firm. Based on these two contingencies, we categorize financing instruments into four types: common equity (common stock), convertible securities (preferred stock and convertible debt), transactional debt (corporate bonds), and relational debt (bank and commercial loans). From the experiences of 39 petroleum firms during the period 1976-2005, we found R&D investment has a positive effect on the use of common equity, a U-shaped effect on the use of convertible securities, and an inverted U-shaped effect on the use of relational debt to raise capital. These effects are sustained over several years.  相似文献

This paper examines the roles of international assignments and other forms of researcher mobility inside the integrated R&D networks of six of the largest European pharmaceutical companies. From in-depth interviews with R&D managers and scientists it is found that, while the use of international assignments is both limited and often not aimed specifically at the transfer of knowledge, other forms of short-term mobility are widely employed. But what is transferred through such short-term visits is narrow in focus and often related to specific projects whereas international assignments enable the transfer of broader and more complex knowledge. The potential impact of these changes in the inter-unit mobility patterns of researchers may be to limit both the exploitation of potential synergies across disciplines and the creation of enduring and strong personal ties among researchers working in distant locations.  相似文献

China has become a hot spot of R&D internationalization and a growing number of Taiwan-based firms have indeed set up R&D units in China. Taking into account China's substantial regional variations in economic development, innovation capacity, and knowledge productivity, such notions as regional innovation system (RIS) and local innovative milieu may become more relevant to the study on relationships between China and its inward R&D internationalization. Therefore, the key issue for this paper is what locational advantages of an RIS within a host country affect the network linkages and networking strategy of multinational corporations’ (MNCs’) offshore R&D units. The paper aims to enrich the current understanding of R&D internationalization in several ways. First, the paper attempts to examine the R&D networking underlying R&D internationalization by Taiwan-based firms in China, with particular reference to the sub-national level inside China. Second, the paper tries to establish a link between the literature of R&D internationalization and that of RIS, with a modified version of Dunning's eclectic paradigm. Efforts are made to map the relationship between foreign subsidiaries’ local R&D networks and their host RISs inside China. Third, the paper takes advantage of a government databank to adopt a quantitative approach, the Seemingly Unrelated Bivariate Probit Regression model, with foreign subsidiaries as the unit of analysis, to highlight the role played by some aspects of the RIS in determining the local R&D networking of Taiwanese subsidiaries in China. Our evident shows that MNCs’ offshore R&D units that purse home-based technology exploitation strategy, the mainstream strategy regarding the developing host country, tend to be located in a host region with a strong knowledge application and exploitation subsystem, while an RIS with a strong knowledge generation and diffusion subsystem, within such a developing country as China, may induce MNCs’ local R&D units to pursue home-base technology augmenting strategy. On balance, not only the location choice but also the local R&D linkages of MNCs’ offshore subsidiaries are related to appropriate fits between the RIS and the subsidiaries’ innovation network inside the host country.  相似文献

This paper aims to disentangle the mechanisms through which technological similarity between acquiring and acquired firms influences innovation in horizontal acquisitions. We develop a theoretical model that links technological similarity to: (i) two key aspects of post-acquisition reorganization of acquired R&D operations – the rationalization of the R&D operations and the replacement of the R&D top manager, and (ii) two intermediate effects that are closely associated with the post-acquisition innovation performance of the combined firm – improvements in R&D productivity and disruptions in R&D personnel. We rely on PLS techniques to test our theoretical model using detailed information on 31 horizontal acquisitions in high- and medium-tech industries. Our results indicate that in horizontal acquisitions, technological similarity negatively affects post-acquisition innovation performance and that this negative effect is not mediated by the reorganization of the acquired R&D operations. However, replacing the acquired firm's R&D top manager leads to R&D productivity improvements that positively affect innovation performance.  相似文献
