Investments in research and development (R&D) have played a key role in promoting productivity improvements and economic growth. This paper explores the economics effects of public R&D investment funding in Brazil, taking into account the changes in total factor productivity (TFP) in high-, medium- and low-technology sectors. Public funding plays an important role in the development of R&D activities in Brazil and its participation has increased since 2010. Our paper simulates a withdrawal of R&D investments and TFP linked to public financing from an R&D-based computable general equilibrium (CGE) model, which recognizes the stock-flow relation between R&D investment and knowledge capital. Without public R&D investment funding, the main findings indicate losses in TFP, adverse effects on the formation of physical capital, shrinkage of more intensive R&D industries, and more future dependence on the public sector for knowledge stock, especially for education.  相似文献

The research and development manager allocates R&D funds to maximize the expected discounted net value of the R&D programme. Because public R&D managers do not have the same market discipline (or rewards) as private R&D managers, public R&D managers require a methodology for maximizing the expected net benefits. The US National Research Council of the National Academies in Prospective Evaluation of Applied Energy Research and Development at DOE (Phase One): A First Look Forward (2005) proposed a cost-benefit methodology to evaluate US Department of Energy's Research, Development, and Demonstration (RD&D) programmes. This paper specifies and extends this methodology, e.g., by adding cost targets into each stage of the RD&D process. Expected benefits are modelled as a function of funding levels, stage durations, stage transition probabilities, and target costs. With this method, the paper determines an optimal allocation of pre-prototype R&D funding, given a total funding constraint for an advanced energy system.  相似文献

This paper analyzes how different institutional structures shape the research and development (R&D) of genetically modified crops (GM-crops). Whether this R&D is conducted within companies, cooperatives or public research organizations (both publicly and privately funded R&D) is expected to influence the type of crops and traits that are developed and therefore the effects on society and ecosystems that potentially could follow from the use of GM-crops. This issue is analyzed empirically by statistical analysis of 1323 notifications for field trials with GM-crops that have been submitted under two EU Directives in seven European countries. The results show that the type of R&D organization influences the traits and crops that are developed. Companies are more likely to submit notifications that concern GM-crops that secure the potential for profit than are other types of R&D organizations, while R&D organizations that are purely publicly funded are more likely to submit notifications that only concern biosafety research than are cooperatives and companies. Consideration of the environment, food safety and food security might justify institutional reforms of R&D of GM-crops. This might include increased public funding combined with changes in intellectual property rights.  相似文献

In this paper, we define public technology infrastructure to mean public resources that bring new R&D into existence. Examples are public research that yields knowledge spillovers and government contracts that broker new research. Using this definition we explore the effect of public infrastructure on cooperative R&D, especially R&D sourcing and research joint ventures (RJVs). Our findings strongly suggest that public infrastructure promotes cooperative R&D. We begin by studying the role of federal laboratories in R&D sourcing by private laboratories, finding that sourcing increases as a result. Then we examine patents arising from RJVs sponsored by the Advanced Technology Program (ATP). We find that R&D subsidies as well as difficulty and novelty increase patents produced by the RJVs. Contractual oversight by ATP has no direct effect but an indirect effect appears to exist, since firms value ATP oversight more highly for more difficult and novel projects, and these produce more patents.  相似文献

This paper investigates the role of public knowledge partnerships in EU-funded framework programmes (FP) on knowledge creation across a sample of European countries. Different from previous studies, we investigate whether the impact of participation in FP on new knowledge (patents) differs across private companies, universities and public research centres. We find that, while all institutional sectors benefit from joint projects, the main benefits (in terms of patenting activity) go to universities and public research centres, while private companies benefit less. We also find evidence of important complementarities between participation in international research projects and internal innovation drivers (researchers), thus highlighting the crucial role of domestic absorptive capacity for fully benefiting from international cooperation in R&D projects.  相似文献

The quality of academic research and research undertaken at public laboratories is an important determinant of successful technology transfer. Corporate innovativeness may benefit considerably from scientific discoveries at universities or public laboratories and from the availability of locally well-trained scientists and graduates. The extent to which quality matters is investigated for 86 European regions in seven countries between 1997 and 2007. We find that regions hosting research departments at the forefront of science produce significantly more inventions and more innovations, whereas the mere presence of R&D personnel in universities has no significant impact. The production of patents in high-technology domains instead does benefit from the presence of R&D personnel in public laboratories. These results complement the existing evidence on the relationship between public research and spatial distribution of innovation.  相似文献

This paper examines the effect of network properties on the performance R&D joint projects. In particular, we examine the impact of network cohesion, diversity and shape on the performance of these of exploration and exploitation R&D projects. We test these measures using data on projects from European R&D networks developed under the framework of Eureka projects. The empirical results indicated some network properties enhance the project’s performance and these differ depending on the kind of technological project developed. Our results suggest a lower heterogeneity, greater cohesion and network centralisation in exploitation than in exploration projects. Our findings show different types of structures depending on the aim of the joint project and that there exist different degrees of cohesion between the partners that comprise the core and the peripheral nodes.  相似文献

Patents are conventionally regarded as representing post-procurement of rights based on results of research and development (R&D). Patents can also be regarded as factors promoting R&D itself. In this study, the author examines the strategic meaning of patents in R&D through analyses of the R&D processes at Canon Inc., which is widely considered to submit patents strategically. The author identified characteristic behaviour related to patent acquisition in the R&D of inkjet printers. Canon constructed a strong patent group precisely by editing patents submitted earlier. Characteristic patent submissions were also identified: they elevated the obtained R&D results to higher concepts as milestones of R&D. These findings are discussed from the viewpoint of the meaning of patents for R&D and the possibility of effective R&D at the patent stage.  相似文献

ABSTRACT

This study highlights the importance of founders’ human capital on firms’ absorptive capacity for explaining the external knowledge sourcing (licensing-in and joint R&D) of start-up firms, using panel data from original questionnaire surveys conducted in Japan. The results of a probit model with an endogenous regressor show that firms managed by founders with a high level of specific human capital, measured as prior innovation experience and industry-specific work experience, tend to engage in external knowledge sourcing because of their superior absorptive capacity. The findings indicate that this type of human capital also promotes research and development (R&D) investment. Contrariwise, this study finds that firms managed by founders with a high level of general human capital, measured as educational attainment, tend to invest more in R&D, which enhances their absorptive capacity and thereby promotes external knowledge sourcing. Finally, the implications of these findings are discussed from the perspective of public policy.  相似文献

This paper aims at investigating the role of different types of proximity on the technological activity of a region within the context of a knowledge production function, where R&D expenditure and human capital are the main internal inputs. We thus assess to what extent the creation of new ideas in a certain region is enhanced by knowledge flows coming from proximate regions. In particular, we examine in detail different kinds of proximity by combining the usual geographical dimension with the institutional, technological, social and organizational proximity. The analysis is implemented for an ample dataset referring to 276 regions in 29 European countries (EU27 plus Norway, Switzerland) over the last decade. Results show that human capital and R&D are clearly essential for innovative activity with the former being much more effective in driving the production of knowledge. As for the proximity and network effects, we find that technological proximity outperforms the geographic one, whilst a limited role is played by social and organizational networks. As a result, the first policy message is that European regions still need to focus on policies aimed at increasing the endowments of well-educated labour force and therefore their knowledge base. Furthermore, we need innovation policies based on each region's specific innovation potential, due to the existing differences in geographical, cognitive, institutional, social and organizational structures and networks.  相似文献

Multilateral indices of total factor productivity (TFP) allow efficiency comparisons between ten European Union countries and the United States from 1973 to 1993. Differences in TFP levels are then explained by land quality differences, public research and development (R&D) expenditures, education levels, private-sector patents, international spillovers of public R&D, and private-sector technology transfer. There is evidence that public R&D results in limited knowledge spillovers between the European countries and the United States. However, the use of international patent data from the Yale Technology Concordance shows not only that patents matter, but also that private sector technology transfer may be the dominant force in explaining TFP trends. The United States and the European Union countries with more advanced research systems (Netherlands, Denmark, France, and Belgium) converge in a high-growth club, while Germany, Luxembourg, Greece, Italy, Ireland, and the United Kingdom form the slow-growth group. Ignoring knowledge spillovers and technology transfer leads to biased estimates of R&D elasticities, which is hardly surprising since the private sector is now spending more than the public in some of these countries. Thus, the estimated rate of return to public agricultural R&D falls from over 60% in the closed economy model to 10% in the model that takes account of international spillovers. (JEL Q16)  相似文献

The concentration and dispersion of innovative activities in space have been largely explained and evidenced by the nature of knowledge and the geographical extent of knowledge spillovers. One of the empirical challenges is to go beyond this by understanding how the geography of innovation is shaped by particular structural properties of knowledge networks. This paper contributes to this challenge, focusing on the particular case of global navigation satellite systems at the European level. We exploit a database of R&D collaborative projects based on the fifth and sixth European Union Framework Programs, and apply social network analysis in economic geography. We study the properties both of the network of organizations and the network of collaborative projects. We show that the nature of the knowledge involved in relationships influences the geographical and structural organizations of the technological field. The observed coexistence of a relational core/periphery structure with a geographical cluster/pipeline one is discussed in the light of the industrial and geographical dynamics of technological standards.  相似文献

This paper contributes to the knowledge-based explanation of R&D networks. It argues that knowledge overlap and novelty are complementary inputs of a R&D alliance, in forms that depend upon the exploration breadth and depth of the R&D activity. The paper investigates how the hypothesis of specialization of the knowledge endowments can recover a number of characteristic empirical properties of a pattern of R&D collaboration in the economy. Implications for network evolution are discussed.  相似文献

Whereas the provision of R&D subsidies has been central to public policy for many years, governments have recently become increasingly involved in stimulating cooperation for innovation and R&D. In many countries, financial support for technology intermediaries has become one of the key measures of indirect public support. However, little research has assessed the impact of indirect policy measures. In this paper, we shed light on the conditions under which technology intermediaries contribute to knowledge and networking outcomes generated by the firms that call upon them. We hereby focus on firm network and competence additionality as measures for cognitive capacity additionality and study the impact of technology intermediaries on firms. In doing so, we distinguish between R&D and R&D related activity technology intermediaries engage in. The results indicate that absorptive capacity of the technology intermediary does not affect cognitive capacity additionality generated by firms in R&D activities, while the results for R&D related activities are mixed and depending on the type of cognitive capacity additionality studied. The absorptive capacity of firms does not directly affect cognitive capacity additionality, but the results of mediation analysis show that firms with higher levels of absorptive capacity use the services of the technology intermediary more intensively, and subsequently generate higher levels of cognitive capacity additionality.  相似文献

Management of university–industry research collaboration (hereafter UIC) is the key to its success. In this respect, government can play an essential role in UIC. A public subsidy for research and development (hereafter R&D) is not only an important financial support for UIC but may also serve as a useful means of promoting trust among UIC members, resulting in higher innovation performance. However, few empirical studies have investigated the role a public R&D subsidy plays in promoting trust in UIC. To this end, by using original survey data, this study examines empirically whether a public R&D subsidy for UIC contributes to trust formation and, thus, to higher innovation performance based on trust. Our findings suggest that a public R&D subsidy promotes trust formation, which then increases the innovation performance of UIC participants, partially mediating the more direct effects of R&D subsidy on innovation performance.  相似文献

This paper investigates empirically different ways to organize research and development (R&D) within Swiss firms. Based on a longitudinal data set comprising three cross-sections (1999, 2002, and 2005) of the Swiss Innovation Survey, four different types of R&D strategies could have been separated; firms combine in-house R&D with R&D co-operations (coop) or in-house R&D with external R&D (buy), or they conduct in-house R&D, external R&D, and R&D co-operations (mixed), or they exclusively rely on in-house R&D (make). It is the aim of this paper to understand what drive firms to go for different strategies. Based on econometric estimations controlling for correlations between the dependent variables and endogeneity among the independent variables, it was found that concepts related to the absorptive capacity, incoming spillovers, and appropriability, the importance of different knowledge sources, the competitive environment, costs, and skill aspects as well as technological uncertainty are essential factors to determine a firm's decision to choose a specific way to organize R&D.  相似文献

In terms of economic development policies, public research and development (R&D) investment may be one of the most critical and useful tools in Taiwan, having frequently played a role in leading related overall investment in Taiwan. Although the impact channels of R&D investment are varied and complex, its benefits in terms of the development of human capital, industrial productivity, and basic research are clear. With the rapid growth of the private sector in the Taiwan economy, it is, however, debatable whether the government should continue to use the public financial budget to invest in R&D. By using a computable general equilibrium (CGE) model to simulate the impact of public R&D investment on the economy in Taiwan, the empirical evidence of the present paper is that public R&D investment gives rise to different short-term and medium-term impacts on real GDP that are mostly felt in the third or fourth years of their implementation among different industries. These impacts then gradually converge back to equilibrium in the long run. Public R&D investment boosts the technology of high-tech industries and increases exports, but it also crowds out the output of primary industries. Although the public R&D investment has a positive effect on the real wage, its effect on inflation should not be overlooked. Because of the pros and cons surrounding the impact of public R&D investment on industries and the economy, the study provided by the present paper can serve as valuable reference not only to decision-makers in government agencies but also to academic researchers.  相似文献

This paper reports results for a well established production function that includes research and development (R&D). By assuming zero depreciation, it can be used to provide estimates of excess social rates of return to R&D. The estimates distinguish spending on product and process innovations for three US manufacturing industries. The results suggest that, while excess social rates of return are found to be negative for product R&D, they are positive for process in each of the industries. They therefore suggest some scope for public R&D subsidies or tax benefits to process R&D but not to product R&D.  相似文献

Against the backdrop of mediocre growth prospects in many countries, governments should do more to promote private investment in research and development (R&D). Public fiscal policies and the characteristics of wage formation are key as they affect both the incentives that firms face and their resources. This paper studies their impact at the macro level in a panel of 14 OECD countries since 1981, while we also account for the impact of unobserved common factors like the world level of knowledge. Tax incentives, government intramural expenditures on R&D, public R&D subsidies (if they are not too low nor too high) and especially investment in tertiary education, encourage business R&D investment. Wage moderation may also contribute to innovation, but only in fairly closed economies and in economies with flexible labour markets. In highly open economies with rigid labour markets, high wage pressure promotes investment in R&D. Innovation may then be the only competitive strategy for firms.  相似文献

This study adopts a Social Network Analysis (SNA) perspective to investigate global R&D internationalisation patterns of the pharmaceutical industry. We use co-inventorships identified in pharmaceutical patents granted by the US Patent and Trademark Office (USPTO) between 1996 and 2013, giving rise to an international collaboration network by drawing a cross-country link when a patent lists at least two inventors located in different countries. We describe changing R&D internationalisation patterns by exploring network structures as a whole as well as the changing role of different countries. The results show that R&D internationalisation indeed has gained momentum in pharmaceutical innovation, in particular after the year 2006. The network has developed from a mono-centric, star-like network – with the USA constituting the only hub – to a more distributed and dense network. The relative decline of the USA has not taken place at the expense of emerging economies but at the expense of European countries.  相似文献
