Electricity sector liberalisation and innovation: An analysis of the UK's patenting activities 总被引：1，自引：0，他引：1
Liberalisation has had a marked effect on innovative activities in the electricity industry. In particular, electricity reforms have resulted in a reduction in R&D spending in the sector. R&D and patenting activities are respectively regarded as innovative inputs to and outputs from technological progress. The present paper examines the effect of the reforms on patenting activity in the UK electricity sector. The results indicate that electricity related patents in non-nuclear and renewable technologies have increased in the post-liberalisation period. We attribute this trend to the increased commercialisation of the sector. While this development is positive, we argue that a lasting decline in R&D will in the longer run reduce technological progress and innovation in the sector. In order to maintain the pace of innovation, we discuss the need to design a new framework for innovation systems that is commensurate with the functioning and incentive mechanisms of a liberalised sector. 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 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

By introducing the concept of innovation regimes, the aim of this article is to show how the rapid pace of technological development in the telecom sector may be explained by the close links between the sector's own R&D and the creation of numerous innovations, many of which are radical. In contemporary innovation theory, a theoretical antinomy exists: Whereas, the creation of incremental innovations is variously explained in terms of «rational» responses to markets, dynamics of technological regimes, dominant design, etc., radical innovations, in contrast, are explained in terms of serendipity, chance or haphazard scientific discoveries. Evidence from analysis of innovations in the telecom sector suggests that innovation regimes have provided a capability of coordination, direction and leadership in the creation of many of the radical technological innovations that have emerged in the sector. Thus, one may claim that the strong innovation regimes and high R&D intensity of the telecom sector, at least until recently, have provided a capability of creating innovations on purpose — for a purpose. The policy implications of this contradict some of the assumptions on which the prevailing market-oriented R&D governance models and policies are based — and which are supported by contemporary innovation theories. 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

We analyze Spain's National Pharmaceutical Research Program using detailed firm-level data. We find differences between ex ante announced evaluation criteria and ex post implementation. This suggests that judging R&D programs on their design, rather than their implementation, may be misleading. We also uncover that the apparent discrimination against non-European firms can be interpreted as a premium to having local production facilities. Overall, the program values firms on the basis of criteria, such as R&D investment and patent spending, consistent with empirically tested measures of innovative activity. 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

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 empirical study examines small firms’ strategies for capturing returns to investments in innovation. We find that small firms’ strategies are qualitatively different from those found in earlier studies of both small and large firms. Most of the small firms examined here find informal means of protection, such as speed to market or secrecy, more important than patenting. Only firms with university cooperation—typically R&D intensive and science-based small firms—were likely to identify patents as the most important method of appropriating innovation returns in their field. Thus, the strategic choice for most small firms is between secrecy and speed to market. Firms that cooperate in innovation with horizontal partners or significantly depend on vertical partners tend to prefer speed, whereas process innovators with modest R&D investments or few cooperative R&D activities display a preference for trade secrets. Indeed, cooperation activities greatly influence the choice of intellectual property strategy for small firms. Earlier research has emphasized patents and trade secrets as key strategies of appropriation, yet these strategies do not appear to be very beneficial for small firms engaged in cooperative innovation. These results raise policy questions regarding the functionality of the existing system of intellectual property rights. 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

National defense represents a significant share of most OECD governments’ R&D budgets and an even higher share of their mission-oriented R&D spending. This public R&D investment has focused on research and innovation supporting defense missions, and in many cases the military services of these governments have purchased weapons systems incorporating the resulting technologies. Defense-related R&D investment has influenced innovation in the broader civilian economy of several OECD nations, including the United States, the United Kingdom, and France. The scope and nature of this influence remains uncertain and subject to considerable debate. Nonetheless, policymakers throughout the industrialized economies have expressed interest in “applying the lessons” of defense-related and other mission-oriented R&D programs to such challenges as climate change. This paper examines the characteristics of defense-related mission R&D programs in the industrial economies, with particular attention to the subset of nations for which reliable longitudinal data on defense R&D spending are available. I highlight the characteristics that distinguish mission-oriented R&D in this field from mission-oriented R&D in other sectors and to point out some significant differences among OECD economies in the structure of their defense-related R&D programs. The discussion also emphasizes the ways in which the unique structure of defense-related R&D limit its utility as a model for mission-oriented R&D programs aimed at other goals. 相似文献

Endogenous technical advance and the stochastic trend in output: A neoclassical approach 总被引：2，自引：0，他引：2
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

The paper adds to the existing literature on the determinants of government spending in Research and Development (R&D) by considering the role of strategic interactions among countries as one of the possible competing explanations, within a spatial econometric framework. We account for several factors affecting national levels of public R&D spending, including (i) the international context – i.e. Lisbon strategy; (ii) country characteristics – level of private R&D, GDP, trade openness and the National System of Innovation; (iii) countries’ similarities in relation to (a) trade and economic size and (b) sectoral specialization. The analysis is carried out on 14 European countries. First, we find that factors traditionally affecting the level of public R&D expenditure, such as the scale of the national economy, trade openness, sectoral specialization and private R&D, significantly influence the level of public R&D in European countries between 1994 and 2006. Interestingly, the introduction of the Lisbon strategy does not seem to have affected changes in the levels of public R&D spending. Second, by using different weight matrices, we confirm the existence of strategic interactions in relation to R&D spending among European countries with similar economic, international trade and sectoral structure characteristics, though not geographically close. 相似文献

Sourcing technological knowledge through corporate acquisition: Evidence from an international sample of high technology firms 总被引：2，自引：0，他引：2
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

The adverse economic impacts of the 1962 Kefauver-Harris Amendments to the Food, Drug and Cosmetic Act have transformed the U.S. pharmaceutical industry. The key elements of this transformation include declining rates of innovation, huge increases in R&D costs and risks, lowered profitability, and an erosion of U.S. technological leadership. U.S. pharmaceutical firms must develop new, creative R&D strategies in order to cope with this complex and demanding environment. U.S. firms have responded to more stringent domestic regulation by sharply increasing both foreign R&D expenditures and initial clinical testing of new chemical entities at foreign locations.New patterns of project selection strategies have begun to emerge in the 1970s. As the total number of R&D projects has been cut back, pharmaceutical firms have focused resources on those disease areas with the highest epidemiological importance. To cope with the increasing riskiness of drug R&D firms have shifted dollars from research to development. Pharmaceutical firms are also likely to alter their strategies for discovering new drugs. As firms reduce explorative, basic research, more structured, engineering approaches will receive increased emphasis. Because individual drug companies are likely to have reduced capacity for originating drugs within their own laboratories, competition among firms for access to new compounds and research ideas is likely to in tensify. 相似文献

Innovation activities, use of appropriation instruments and absorptive capacity: Evidence from Spanish firms 总被引：2，自引：1，他引：2
This article empirically investigates the relationship between innovation activities of firms, their use of appropriation instruments and their absorptive capacity. We study a wide range of manufacturing and service industries, not just high-tech, and a wide range of innovation activities, not just R&D. We use multilevel logit models for complex samples to disentangle industry from firm-specific effects. We find that within an industry, firms that invest in appropriation instruments to reduce outgoing spillovers tend to conduct more R&D and downstream activities than firms that do not. Acquisition of technology is not related to the use of appropriation instruments. The effects of incoming spillovers (measured through absorptive capacity) on innovation activities of firms are industry specific and stronger for firms that invest in appropriation instruments. For this type of firm, both the capability to scan the external environment for technology and the capability to integrate new technology are related to the innovation activities. For firms that do not invest in appropriation instruments, only scanning capabilities are related. 相似文献

This paper studies the impact of R&D spending on output as well as forecasting the impact of a regionally enhanced R&D tax credit on the ‘user cost’ (or price) of R&D expenditure and subsequently the demand for R&D. The example we use of a ‘disadvantaged’ region is Northern Ireland (partly because it has the lowest levels of R&D spending in the UK, and partly because the necessary data is available for this region). We find that in the long run, R&D spending has a mostly positive impact on output across various manufacturing industries. In addition, plants with a zero R&D stock experience significant one-off negative productivity effects. As to the adjustment of R&D in response to changes in the ‘user cost’, our results suggest a rather slow adjustment over time, and a long-run own-price elasticity of around −1.4 for Northern Ireland. We also find that to have a major impact on R&D spending in the Province, the R&D tax credit would need to be increased substantially; this would be expensive in terms of the net exchequer cost. 相似文献
