Although R&D spillovers play a key role in the battle for technological leadership, it is unclear under what conditions firms build on and benefit from the discoveries of others. The study described here empirically examines this issue. The findings indicate that, depending on technological opportunities, firm size and competitive pressure, the net impact of R&D spillovers on productivity can be either positive or negative. Specifically, we find that although spillover effects are positively associated with the technological opportunities that a firm faces, this relationship is reversed when firm size is considered. Whilst external R&D affects large self-reliant firms negatively, its impact on the productivity of smaller firms (who usually introduce incremental innovations that are characterized by a strong reliance on external technologies) is positive, and even higher than that of their own R&D. We also demonstrate that the economic payoff for firms’ own R&D is lower when they face intense competition. In cases of low-appropriability, however, spillover effects are more positive, allowing firms to increase their performance using the inventions of others.  相似文献

R&D subsidies designed to encourage innovation efforts by firms may have intended and unintended effects on the way they organize their innovation process. We present empirical evidence on how R&D subsidies affect firms’ R&D cooperation strategies. In particular, we investigate whether receiving public R&D subsidies affect the probability that a firm will set up an R&D partnership with a public research organization (PRO), or with other firms. Our main findings are: (i) public support significantly increases the chances that a firm will cooperate with a PRO, and (ii) public support also increases the likelihood that a firm will establish private partnerships, but to a smaller extent and only when firms have intangible knowledge assets. These results suggest that public R&D programmes trigger a behavioural change in firms’ R&D partnerships, alleviating barriers to cooperation.  相似文献

This paper focuses on the dual role of R&D - knowledge generation and the technological-competence-enhancing effect of R&D - and its implication for the endogenous evolution of R&D productivity and the pattern of firm growth. In particular, based on the evolution of firm-specific R&D productivity or technological competence, this paper derives a simple R&D-based model of firm growth capable of explaining various aspects of firm growth. The model proposes three prototype patterns of firm growth, depending on both firm- and industry-specific characteristics. The former includes firm-specific technological-competence-enhancing capability and the initial level of technological knowledge, and the latter includes industry-specific R&D appropriability. Specifically, firms with low technological-competence-enhancing capability tend to follow a convergent growth pattern in which firm growth gradually declines, while firms with high technological-competence-enhancing capability tend to exhibit either a sustained or a vicious growth pattern depending on the initial size of their technological knowledge stock. An empirical analysis of unique data on firm growth and technological capability provides supportive evidence for the role of technological-competence-enhancing capability in conditioning the pattern of firm growth.  相似文献

This paper shows that firm heterogeneity in technological competence, rather than differences in industry-specific characteristics, is the primary condition determining the long-debated relationship between firm size and R&D. Specifically, by utilizing a formal model of firm R&D that shows that profit-maximizing firm R&D intensity is determined jointly by firm-specific technological competence and consumer preference regarding quality and price, this paper suggests that firm size affects firm R&D intensity not directly, but through its influence on firm-specific technological competence. In particular, four predictions are drawn and tested empirically: (1) in general, the size-R&D relationship is less-than-proportional or inverted U-shaped, especially for low-technological-competence firms; (2) however, the common less-than-proportional relationship disappears, and a more-than-proportional relationship becomes increasingly likely, for firms with high levels of technological competence, plausibly due to competence-enhancing, learning economies of scale and/or scope in R&D; (3) firms with larger accumulated R&D experience are, ceteris paribus, less likely to exhibit the common less-than-proportional relationship; (4) among industries, a greater within-industry departure from the proportional size-R&D relationship is expected for industries with seemingly high, rapidly changing technological-opportunity conditions. These predictions, especially pertaining to the conditioning role of technological competence in the size-R&D relationship, are empirically supported by the unique data by the World Bank.  相似文献

This paper analyses market valuations of UK companies using a new data set of their R&D and IP activities (1989-2002). In contrast to previous studies, the analysis is conducted at the sectoral-level, where the sectors are based on the technological classification originating from Pavitt [Pavitt, K., 1984. Sectoral patterns of technical change. Research Policy 13, 343-373]. The first main result is that the valuation of R&D varies substantially across these sectors. Another important result is that, on average, firms that receive only UK patents tend to have no significant market premium. In direct contrast, patenting through the European Patent Office does raise market value, as does the registration of trade marks in the UK for most sectors. To explore these variations the paper links competitive conditions with the market valuation of innovation. Using profit persistence as a measure of competitive pressure, we find that the sectors that are the most competitive have the lowest market valuation of R&D. Furthermore, within the most competitive sector (‘science based’ manufacturing), firms with larger market shares (an inverse indicator of competitive pressure) also have higher R&D valuations, as well as some positive return to UK patents. We conclude that this evidence supports Schumpeter by finding higher returns to innovation in less than fully competitive markets and contradicts Arrow [Arrow, K., 1962. Economic welfare and the allocation of resources for invention. In: Nelson, R. (Ed.), The Rate and Direction of Inventive Activity. Princeton University Press, Princeton], who argued that, with the existence of IP rights, competitive market structure provides higher incentives to innovate.  相似文献

This study aims to evaluate whether firms located in clusters invest more intensively in research and development (R&D) than their non-clustered counterparts. Specifically, it proposes a model of firm R&D and tests empirically its implications for the effect of being located in a cluster on firm R&D intensity. The key ideas underlying the theory are as follows: (1) due either to natural excludability or to a high degree of stickiness of R&D-opportunity-bearing technological knowledge, geographical proximity per se is limited in the (automatic) spillover of knowledge with promising R&D opportunities to nearby firms; (2) geographical proximity may, however, help enhance the effectiveness or efficiency of knowledge exchange through market mechanisms (e.g., through contract R&D, R&D collaboration); (3) potential advantages (or disadvantages) in firm R&D of being located in a cluster also depend on the degree of asymmetry in technological competence among firms located in the cluster. The key ideas are supported by an empirical analysis of a multi-industry, multi-country data set compiled by the World Bank. In particular, the results show that being located in a cluster per se actually has a negative effect on firm R&D intensity, which is in contrast to the conventional wisdom of pure or automatic localized knowledge spillovers, as far as firm R&D intensity is concerned.  相似文献

This paper examines how innovation strategy influences firms’ level of involvement with university-based research. Our results suggest that firms with internal R&D strategies more heavily weighted toward exploratory activities allocate a greater share of their R&D resources to exploratory university research and develop deeper multifaceted relationships with their university research partners. In addition, firms with more centralized internal R&D organizations spend a greater share of their R&D dollars on exploratory research conducted at universities. In contrast to other external partners, we find evidence suggesting that universities are preferred when the firm perceives potential conflicts over intellectual property.  相似文献

The Fraunhofer-Institut für Systemtechnik und Innovationsforschung (ISI) is at present engaged in evaluating a number of technology policy programs designed to promote research, development and innovation in small and medium-sized firms. These studies try to determine the extent to which these programmes have an impact upon the innovative activities of firms.In this connection, it was also attempted to measure the innovation output. The level of innovation of a firm is innovation ouput. The level of innovation of a firm is procedure involves a number of problems (self-assessment of firms in view of insufficient market transparency, distortion due to self-portraits reflecting the firms' own interests). We tried to mitigate such distortions by two approaches. Firstly, firms were asked for their technologically new products, the term “new” being applied (a) to the firm and (b) to the areas of product application. As a result of this two-tier procedure, firms supplied rather realistic answers. Secondly, supplementary questions were asked about sales figures, the competitive technological situation (nationally and internationally), expenditure on R&D, patents, stages of innovation, aims of innovation, etc.The paper presents the results obtained to date on the innovation output of firms within the framework of an evaluation of the largest programme at present devoted to promoting R&D and innovation in small and medium-sized firms . The results are based on a representative sample of approximately 4,500 small and medium-sized firms (up to 1,00 employees) with R&D activities in the Federal Republic of Germany.  相似文献

We assess the impact of R&D manpower diversity on firms’ technological performance. Relying on insights from two theoretical perspectives on team diversity (i.e. social categorization perspective and information decision-making perspective), we hypothesize that both demographic and task-related sources of diversity within firms’ R&D workforce influence technological performance. In addition, we expect that these two dimensions of diversity interact with each other. To test our hypotheses, we rely on survey data from 938 Singaporean firms, providing in-depth information on three sources of demographic diversity (i.e. gender, age, and nationality of R&D employees) and two sources of task-related diversity (i.e. educational and knowledge area background of R&D employees). Our findings point to significant interactions between different sources of R&D manpower diversity. In particular, we identify substitutive relationships between (a) educational and gender diversity, and (b) nationality and knowledge area diversity.  相似文献

Complementary insights from Transaction Cost Economics (TCE) and the Resource-Based View (RBV) of the firm are combined to predict the relationship between firm specific technological knowledge and patterns of integration within organizational boundaries. The findings show that the level of Research and Development (R&D) intensity (representing the creation of firm specific technological knowledge) has an inverted U-shaped relationship with the propensity of firms to integrate activities within organizational boundaries. At low levels of R&D intensity, firms’ propensity to integrate their activities is low, but increases with escalating levels of R&D intensity in order to avoid the misappropriation of value generated by technological knowledge. However, beyond a certain R&D intensity level, the propensity to integrate activities declines, since the level of technological knowledge is high enough to prevent imitation by third parties. As expected we further find that firms which follow this integration pattern outperform those which do not. As the level of R&D intensity increases, the integration of production and marketing activities enables firms to improve performance until a certain R&D intensity threshold, after which such integration negatively affects performance.  相似文献

This paper builds on agency and institutional theory to extend the analysis of the effects of ownership and control on R&D investments by considering the influence of different types of ownership and of institutional corporate governance systems. Our empirical analysis is based on a unique dataset of 1000 firms publicly-traded in six European countries (France, Germany, Italy, Norway, Sweden and the UK). Controlling for industry- and firm-level effects, our findings show that higher shareholding by families is negatively associated with R&D investment. Moreover, widely-held firms invest less in R&D in the United Kingdom than in Continental European countries, thus suggesting the existence of a greater pressure towards the reduction of R&D in market-based governance systems. The results are robust against possible sample selection biases due to firms’ discretional R&D disclosure.  相似文献

This paper explores the impact of a specific R&D policy instrument, the Italian Fondo per le Agevolazioni della Ricerca (FAR), on industrial R&D and technological output at the firm level. Our objective is threefold: first, to identify the presence or absence of private R&D investment additionality/crowding-out within a pooled sample and in various firm subsets (identified by region, size, level of technology, and other features), while also taking into account the effect of single policy instruments or mixes of them. Secondly, to analyse the output (innovation) additionality by comparing the differential impact of privately funded R&D and publicly funded R&D expenditure on applications for patents filed by firms. Thirdly, the paper will compare the structural characteristics of firms showing additionality with those of firms showing crowding-out, in order to determine the firm characteristics associated with successful policy interventions. Our results suggest that FAR is effective in the pooled sample, although no effect emerges in some firm subsets. In particular, while large firms seem to have been decisive for the success of this policy, small firms present a more marked crowding-out effect. Furthermore, the firms’ growth strategies and ability to transform R&D input into innovation output (patents) seem to have a positive effect in terms of additionality.  相似文献

We analyze the influence of a regional economic integration agreement (REIA) on a firm's investments in research and development (R&D). A country's entry into a REIA creates two competing influences on the firm's R&D investments. On the one hand, increased competition in product markets after the REIA would induce the firm to invest in internal R&D to improve its distinctive technological competitiveness. On the other hand, better access to sources of inputs in factor markets after the REIA would induce the firm to purchase external R&D because it can outsource technology more easily. Surprisingly, the empirical analysis shows that the REIA's impact on R&D investment is driven primarily by product markets rather than by factor markets. After the REIA, product markets induce firms not only to invest more in internal R&D but also purchase more external R&D. In contrast, after the REIA factor markets have limited influence on internal or external R&D investments.  相似文献

We study differences in the returns to R&D investment between German manufacturing firms that sell in international markets and firms that only sell in the domestic market. Using firm-level data for five high-tech manufacturing sectors, we estimate a dynamic structural model of a firm's discrete decision to invest in R&D and use it to measure the difference in expected long-run benefit from R&D investment for exporting and domestic firms. The results show that R&D investment leads to higher rates of product and process innovation among exporting firms and these innovations have a larger economic return in export market sales than domestic market sales. As a result of this higher payoff to R&D investment, exporting firms invest in R&D more frequently than domestic firms, and this endogenously generates higher rates of productivity growth. We use the model to simulate the introduction of export and import tariffs on German exporters, and find that a 20 % export tariff reduces the long-run payoff to R&D by 24.2 to 46.9 % for the median firm across the five industries. Overall, export market sales contribute significantly to the firm's return on R&D investment which, in turn, raises future firm value, providing a source of dynamic gains from trade.  相似文献

This paper presents an empirical analysis of the determinants of research cooperation between firms and Public research organisations (PROs) for a sample of innovating small and medium-sized enterprises (SMEs). The econometric analysis is based on the results of the KNOW survey carried out in seven EU countries during 2000. In contrast to earlier works that provide information about the importance of PROs’ research, we know the number of firm/PRO collaborative research and development (R&D) projects. This allows us to study the determinants of firm collaboration with PROs in terms of both the propensity of a firm to undertake R&D projects with a university (do they cooperate or not) and the extent of this collaboration (number of R&D projects). Two questions are addressed. Which firms cooperated with PROs? And what are the firm characteristics that might explain the number of R&D projects with PROs? The results of our analysis point to two major phenomena. First, the propensity to forge an agreement with an academic partner depends on the ‘absolute size’ of the industrial partner. Second the openness of firms to the external environment, as measured by their willingness to search, screen and signal, significantly affects the development of R&D projects with PROs. Our findings suggest that acquiring knowledge through the screening of publications and involvement in public policies positively affects the probability of signing an agreement with a PRO, but not the number of R&D projects developed. In fact, firms that outsource research and development, and patent to protect innovation and to signal competencies show higher levels of collaboration.  相似文献

We examine how the ways in which firms geographically configure their global portfolios of R&D units influence the effectiveness of firms’ own R&D investments and of external technical knowledge in enhancing firm performance. Our analysis indicates that the strength of these effects depends on the extent to which firms spread their R&D units across countries (geographic dispersion of R&D) and the extent to which firms establish multiple R&D units within each country (co-location of R&D). We show that geographic dispersion and co-location are associated with distinct value creation and value capture mechanisms and in turn lead to different performance outcomes. Although geographic dispersion enhances the effects of a firm’s own R&D on its performance, R&D co-location limits such effects. These relationships are reversed when we consider the effects of external technical knowledge on firm performance. R&D co-location, rather than geographic dispersion, is what renders the exploitation of external knowledge more effective in enhancing firm performance. Our results suggest that future research should shift its focus from the degree of R&D globalization to how a portfolio is globalized and geographically structured.  相似文献

The aim of the paper is to investigate in a simultaneous equation framework the role of R&D cooperation in the innovation process—in context with other factors—from two specific aspects. First, analysis focuses on the impact of R&D cooperation on firms’ innovation input and output. Second, analysis is undertaken as to how the number of cooperation partners affects the innovation behaviour of firms. Starting with the discussion of theoretically expected effects of successful R&D cooperation on the innovation activities of firms, the importance of inter-organizational arrangements in R&D is empirically investigated in respect of firms in the German manufacturing industry. The estimation results can be summarized as follows: joint R&D is used to complement internal resources in the innovation process, enhancing the innovation input and output measured by the intensity of in-house R&D or the realization of product innovations. On the input side, the intensity of in-house R&D also stimulates the probability and the number of joint R&D activities with other firms and institutions significantly.  相似文献
