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 study examines the technology strategies of 88 technology-based growth companies that went public on the German “Neuer Markt” between 1997 and 2002. The regression analyses show significant positive effects of R&D on growth but negative effects on profitability. The data suggests that firm age is a moderating factor influencing whether technology investments lead to higher growth or profitability in the life cycle of technology-based growth companies. In our sample, higher R&D intensity led to increased sales growth but lower return on sales, but the growth effect was negative and the impact on profitability positive. These results support the significance of company life cycle theories for formulating technology strategies, which suggests that different stages in the development of technology-based firms call for specific levels of R&D intensity to sustain growth and profitability.  相似文献

This paper summarizes the pilot stage of a microeconomic study of the innovation performance through time of young, high-technology Israeli firms. It reports some results for a successful firm designing, producing and selling electronic instruments and systems. The paper begins by surveying some of the difficulties surrounding the collection and organization of data on R&D projects. One of them concerns the definition of the ‘Unit for Analysis’ - the R&D project. Three criteria are suggested for dividing the stream for innovative activities into R&D projects, and these are applied to group the tens of products, accessories and systems included in the analysis into nine projects. The paper subsequently defines a measure of “direct” project performance or profitability estimate - discounted operating profits per unit of fixed costs - and provides estimates based on R&D and sales data for the products of each project. The final sections analyze the variation of project profitability through time. The increasing profitability observed across generations of a product class is attributed to the adaptability of the firm to changes in the environment, particularly to the availability of new technology which requires the swift design and sale of more complex products. The qualitative history of the various projects suggests that this adaptability is due, to a large extent, to the skills, infrastructure and reputation of the firm accumulated from prior projects, i.e. that the “indirect” profitability of the latter is high. Some estimates of the indirect profitability of early projects are presented. A comparison of the spin-off mechanisms observed in the firm analyzed with those observed in firms of other industries is also undertaken.  相似文献

We investigate the prevalence of the motive to source technological knowledge externally through corporate acquisition. Drawing on make-or-buy and organizational learning theories, we infer the implications of this explanation for the acquirers' pre-acquisition innovative characteristics. Using an international sample of 6106 high technology acquisitions during 1984–2000, we assess the contribution of innovative characteristics to the acquisition likelihood. For firms acquiring small private firms and former subsidiaries—but not public targets—the evidence is consistent with three propositions: (1) A firm's commitment to internal R&D is negatively affected by the decision to acquire; (2) Low R&D productivity increases the likelihood of acquisition; (3) A large knowledge stock predisposes firms to acquire because they perceive they are capable of selecting and absorbing targets. We conclude that acquisitions of small private firms and former subsidiaries are a viable R&D strategy to explore a range of potential future innovation trajectories for large public firms.  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

The centrality of firms vis-à-vis regions underlines a general contrast between two models of producing innovations. This paper uses a new database composed of 4262 European chemical patents applied by 693 firms during 1987–1996 to compare the relative effect of firm and regional characteristics on the production of technological “hits” (highly cited patents). By using extensive controls, the main finding of the paper is that technological hits in the “traditional” chemical sectors are explained only by R&D intensity at the firm level and the scale of the research projects. Firm competencies, particularly technological specialisation, are still important in biotechnology. However, the distinct feature of the biotechnology model is that localised knowledge spillovers also matter.  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

Despite widespread dissatisfaction with the quality of scientific information employed in planning and policy-making in public agencies, relatively little is known about the scientific information acquisition behaviors of public managers. The purpose of this paper is to facilitate research on scientific information acquisition in public agencies by suggesting that: (1) planning and policy-making are ‘policy technologies’ and share certain attributes with more traditional technologies; (2) many propositions developed in the literature on information flows in R&D labs are, therefore, helpful in structuring thinking about information flows in public agencies; and (3) it may be possible self-consciously to design social and organizational structures so as to enhance informal flows of scientific information. After gleaning some of the propositions concerning scientific information flows from the R&D management literature, an ‘ideal design’ approach is employed to develop a model in which the social and organizational structures of a public agency optimize scientific information flow.  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

In 1987, Sweden's 20 largest multinationals together operated some 170 foreign R&D units, employing 8100 people, 23% of their total R&D personnel. About 60% of the units were added after 1980, the majority through acquisitions of foreign companies.Four major motives for the operation of foreign R&D units are identified: (1) support to local production (5% of foreign R&D employment); (2) ‘market proximity’, i.e. adaptation of centrally developed products (and processes) to local market conditions (32%); (3) exploitation of foreign R&D results and resources (8%); (4) ‘political factors’, i.e. environmental factors more or less directly influenced by government action (34%). The remaining 20% of employment seemed to be motivated by a combination of factors.The primary aim of the first three types of foreign R&D units is to enhance a company's competitive position in ways not possible from a domestic location. Hence, they should be little cause of concern for Swedish policy makers.  相似文献

This study examined how participation in open innovation communities influences the innovative and financial performance of firms commercializing open source software. Using an original dataset of open source companies in the Netherlands, I found that the community participation–performance relationship is curvilinear. In addition, results indicate that extensive technical participation in open source projects is more strongly related to performance for firms that also engage in social (“offline”) community activities, for companies of larger size, and for firms with high R&D intensities. Overall, this research refines our understanding of the boundary conditions under which engagement in community-based innovation yields private returns to commercial actors.  相似文献

We analyse the impact of R&D cooperation on firm performance differentiating between four types of R&D partners (competitors, suppliers, customers, and universities and research institutes), and considering two performance measures: labour productivity and productivity in innovative (new to the market) sales. Using data on a large sample of Dutch innovating firms in two waves of the Community Innovation Survey (1996, 1998), we examine the impact of R&D cooperation in 1996 on subsequent productivity growth in 1996–1998. The results confirm a major heterogeneity in the rationales and goals of R&D cooperation. Competitor and supplier cooperation focus on incremental innovations, improving the productivity performance of firms. University cooperation and again competitor cooperation are instrumental in creating innovations generating sales of products that are novel to the market, improving the growth performance of firms. Furthermore, customers and universities are important sources of knowledge for firms pursuing radical innovations, which facilitate growth in innovative sales in the absence of formal R&D cooperation.  相似文献

This paper explores the strategic internationalisation of Research and Development (R&D) activities of the world's 100 largest food and beverages (F&B) multinationals (MNEs) in 1996 and 2000 with a sample of nearly 8000 affiliates for each period. We develop a global innovation strategy (GIS) structure where we analyse the R&D internationalisation process of F&B MNEs. We argue that in a fully developed GIS model the sourcing of creative inputs does not come exclusively from a ‘central’ R&D laboratory, but other overseas R&D laboratories or technological affiliates can also undertake genuine knowledge creation activity from capitalising on the scientific heterogeneity fostered in individual host countries as well as distinctive demand conditions. Our results indicate the increasing importance of overseas technological affiliates in the application of a GIS in the leading F&B MNEs, which determine the degree of their technological internationalisation. Two variants of technological affiliates reflect two broad knowledge-related activities, i.e. adaptation and genuine forms of knowledge creation.  相似文献

The relationship between the organizational size and the research productivity of major US pharmaceutical firms was examined. The measure of organizational size was the research budget in dollars, and the measure of research production was the number of drugs introduced during hte 1960's judged be “important therapeutic advances” by a Food and Drug Administration study. Productivity, as distinct from production, was defined as research production per unit of R&D money spent. The conclusions are that research production appears to increase linearly with research budget. There seems to be no linear relationship between productivity and size, but quadratic techniques do give some evidence fro economies of scale in productivity.  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

Inventive and uninventive clusters: The case of Canadian biotechnology   总被引:1,自引:0,他引:1  
We examine factors influencing the relative productivity of different geographic locations. Our analysis of the Canadian biotechnology industry during the 1990s reveals that inventive and uninventive locations are distinguishable within small geographic areas corresponding to roughly 7000 postal addresses. Inventive locations exhibit greater resource scale and technological focus, as well as greater emphasis on R&D investment and public and private collaboration. Comparison of inventive locations across three major metropolitan areas – Vancouver, Toronto and Montreal – indicates, however, that inventive locations vary in their emphasis on technological scale and focus relative to collaboration, and thus that location advantages can develop in distinctive ways.  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

In the recent endogenous growth literature, the trend in output is stochastic, while investment in scientific knowledge is treated as analogous to a capital stock. This paper models both research and development (R&D) and disembodied technical advance using neo-classical equations, which specify the equilibrium stocks as a function of prices and output. The elasticity of R&D in the production function, estimated using factor shares, is time-varying and increasing. Returns to scale are increasing in all factors. The most important aspect of the model is that the equilibrium rate of technical advance is not cyclically invariant, but co-moves with output at business cycle frequencies. This allows the production function to behave as a stochastic trend. Growth accounting demonstrates that long-term variations in the rate of productivity growth have been associated mainly with low-frequency fluctuations in the rate of disembodied technical advance, with secondary effects from the stocks of R&D and physical capital. During the high productivity period 1948–1972, technical advance contributed 1.48 percentage points per year to output, with 0.98 accounted for by R&D. The productivity slowdown of the mid-1970s was accounted by a gradual decline in the effect of R&D, and a more abrupt collapse in disembodied technology. The subsequent productivity revival was associated with two accelerations in disembodied technical advance, the first beginning in the early 1980s, and the second in the mid-1990s. The production function is simulated in a small econometric model. Model simulations find that exogenous shocks to the inflation rate generate significant variations in growth by inducing fluctuations in disembodied technology.  相似文献

Supply and demand conditions that affect technological change in four functional areas of local government service delivery are described and analyzed. A consistent picture of small, fragmented markets, ‘lumpy’ demand, or uncertain markets is found, with demand shaped by a heterogeneous body of local procurement traditions and practices, low municipal technical capabilities, and risk-averse behavior by city officials and engineering consultants. Industries involved share a number of characteristics that bode poorly for industrial investment in innovation: low profit margins and uncertain financial futures. Firms that have the resources to invest in R&D do not tend to focus exclusively on municipal markets. The findings suggest that public policies directed toward improving the municipal market for innovative products by strengthening the cities' technological infrastructure will be more effective than policies directed toward the supply side such as increased R&D support.  相似文献

Cooperation between rivals: Informal know-how trading   总被引:1,自引:0,他引:1  
“Informal” know-how trading is the extensive exchange of proprietary know-how by informal networks of process engineers in rival (and non-rival) firms. I have observed such know-how trading networks to be very active in the US steel minimill industry and elsewhere, and they appear to represent a novel form of cooperative R&D.When one examines informal know-how trading in the framework of a “Prisoner's Dilemma”, real-world conditions can be specified where this behavior both does and does not make economic sense from the point of view of participating firms. Data available to date on the presence and absence of such trading seem to be roughly in accordance with the predictions of this simple model.Although presently documented only as a firm-level phenomenon involving the trading of proprietary technical knowhow, informal know-how trading seems relevant to (and may currently exist in) many other types of situation. Indeed, it may be applicable to any situation in which individuals or organizations are involved in a competition where possession of proprietary know-how represents a form of competitive advantage.  相似文献
