Knowledge intensive services and, in particular, R&D services contribute significantly to innovation in firms. The objective of this paper is to find out which characteristics of firms explain the acquisition of R&D services and to analyse whether there are differences depending on the typology of the supplier (universities, technology centres and consulting firms). Three main conclusions emerge from the econometric estimations carried out with information from a survey of innovative firms in the region of Valencia in Spain. First, the results show that firm size and age matter in the decision to buy R&D services. Second, our results are consistent with the relevance that the literature gives to human capital in absorbing external knowledge. Third, innovation policy has a significant influence on the decision to acquire R&D services, particularly from universities and technology centres.  相似文献

This article analyses the influence of industry characteristics (concentration and technological opportunity), the institutional framework (social capital and spillovers from the public sector) and some firm factors (external and internal R&D) on product innovation in a unique integrated framework. Based on a sample of Spanish industrial firms, these variables were found to be positively related to firms’ product innovation. Also, results show that in institutional environments with significant levels of social capital and spillovers, firms change their innovation strategy focusing on external R&D.  相似文献

In this paper a panel of workers and firms is used to investigate employment composition and dynamics in industries which differ by innovation intensity. To define the latter industry-wide statistics were used (for a subset of 2,800 firms, individual data on R&D expenditures and investments in innovative processes were available from a survey on manufacturing). Firms and workers are observed over the period 1985–1991. The paper document an high rate of labour turnover. Annual separation rates are high in all size-classes, but they decline from 50% in small firms (less than 20 employees) to 13% in large ones (with more than 1,000 employees). Separations are inversely related to an industry's innovative intensity (from 18% in the highly innovative industries to 31% in the traditional industries). A logit model, which controlled for the characteristics of workers and firms, showed that the probability of separation is higher among manual and young workers and decreases monotonically with the firm size. The probability of separation declines as job tenure and, perhaps more importantly, the individual's wage increases. After controlling for these factors, the evidence suggests that the highest probability of separation is in traditional industries, the lowest is in the more innovative industries. The result is strengthened when firm-level data on R&D and other innovative expenditures are used. Other things being equal, firms that invest in R&D have a more stable labour force, and firms that invest in non-innovative processes have a less stable labour force. We therefore find empirical evidence to support the hypothesis that more innovative firms cultivate more durable employer-employee relationships. The fraction of job-to-job moves (with no intervening period of unemployment) on total separations qualifies the turnover of workers. Controlling for firm size, the percentage of job-to-job moves increases fairly regularly with worker's skills and with the industry's innovative intensity. Thus the innovative intensity of he industry appears to have a positive effect on the share of job-to-job moves, while there is some evidence that it lowers the chances of separation. This result may be linked to the skills and specialisations of the workforce; it is certainly related to the higher demand for labour in the High Tech Sectors (where employment is growing) relative to the less innovative sectors.  相似文献

Technological innovation is a key factor for achieving better environmental performances. Its role is even more relevant in local productions system, where innovation density, knowledge spillovers and externalities are concentrated in a circumscribed territory. The paper exploits new data for a sample of manufacturing firms in Northern Italy. New evidence is provided by testing a set of hypotheses, concerning primarily the role of environmental‐devoted R&D, networking activities, quality/nature of industrial relations. The role played by environmental policy pressure, structural firm features and past firm performances is also investigated to account for more exogenous forces. We show that structural characteristics of the firm appear to matter less than R&D, induced policy costs and innovative‐oriented industrial relations. Environmental auditing schemes also show some relevant correlation to innovation adoptions. R&D efforts appear to be associated to networking activities, which substitute for size‐related economies of scale. Overall, endogenous factors driven by firm strategy or local idiosyncratic features matter more than exogenous and structural firm factors.  相似文献

Recent finance literature highlights the role of technological change in increasing firm specific (idiosyncratic) and aggregate stock return volatility, yet innovation data is not used in these analyses, leaving the direct relationship between innovation and stock return volatility untested. The paper investigates the relationship between volatility and innovation using firm level patent data. The analysis builds on the empirical work by Mazzucato (Rev Econ Dyn 5:318–345, 2002; J Evol Econ 13(5):491–512, 2003) where it is found that stock return volatility is highest during periods in the industry life-cycle when innovation is the most ‘radical’. In this paper we ask whether firms which invest more in innovation (more R&D and more patents) and/or which have more important innovations (patents with more citations) experience more volatility in their returns. Given that returns should in theory be higher, on average, for higher risk stocks, we also look at the effect of innovation on the level of returns. To take into account the competition between firms within industries, firm returns and volatility are measured relative to the industry average. We focus the analysis on firms in the pharmaceutical industry between 1974 and 1999. Results suggest that there is a positive and significant relationship between volatility, R&D intensity and the various patent related measures—especially when the innovation measures are filtered to distinguish the very innovative firms from the less innovate ones.  相似文献

We propose a general theory of innovation that illustrates the relative benefits of performing process versus product R&D when firm size is endogenous. A firm's size, scope, and R&D portfolio are shown to reflect the same underlying characteristic of the firm, namely manufacturing efficiency. We demonstrate that efficient firms become larger, have greater scope, and perform more of both process and product R&D. In light of decreasing returns to R&D, this implies small firms obtain more product innovations per dollar of R&D than large firms, which is consistent with evidence we present that small firms are more innovative than large firms as they obtain more patent counts and citations per dollar of R&D.  相似文献

Technological innovation through R&D is a critical element in enhancing and fostering firm performance. In particular, measurement of R&D efficiency throughout the innovation and commercialisation stages is important. However, almost of R&D efficiency-related studies assumed that R&D is a single stage. This study aims at analysing relative efficiency scores throughout the stages of the R&D process using a two-stage data envelopment analysis (DEA) model with a sample of 1039 Korean manufacturing firms. Based on our preliminary results, this study was extended by comparing subsample groups categorised by firm size and industry type. The key findings include: (1) firms show imbalanced R&D efficiency throughout the two stages and (2) R&D efficiency is different by firm size and industry type. The empirical results and findings may assist policy- and decision-makers to enhance R&D efficiency at the firm level. Moreover, introduction of the two-stage DEA model and comparative analysis methods to firm-level data contributes to scholars.  相似文献

This paper reexamines broadly. from the standpoint of innovation, the arguments for vertical integration in the U.S. telecommunications industry in light of structural change since the breakup of the Bell System. While basic and applied research became the casualty of the 1984 breakup and the 1995 AT&T split, there is no evidence that the pace of innovative activity and productivity has slowed. Evidence from R&D and patent data suggests some acceleration of innovative activity. However. the service segment of the industry ceased to be the center of technological innovation. The source of future innovation seems to lie in the telecommunications and Internet equipment firms and independent software firms. The emergence of the competitive stand-alone software industry, combined with a trend towards open operating systems and customer demand for greater flexibility, and growing substitution of technology alliances for in-house R&D appear to have undermined the case for vertical integration in the telecommunications industry. From the standpoint of business strategy, the question of whether a firm like AT&T, notwithstanding its huge investments in cable facilities, can develop distinctive and sustainable capabilities through horizontal expansion and ubiquity and one-stopshopping marketing alone remains open.  相似文献

This paper discusses the sources of product innovation in young innovative companies (YICs), here defined as firms engaged in product innovation and with less than 8 years of activity. In particular, we look at in-house and external R&D and at the acquisition of external technology in its embodied and disembodied components. These input–output relationships are tested on a sample of 2713 innovative Italian firms. A sample-selection approach is applied to study both the determinants of product innovation and the factors affecting the intensity of innovation.Results show that in-house R&D is linked to the propensity to introduce product innovation both in mature firms and YICs; however, innovation intensity in the YICs is mainly dependent on embodied technical change from external sources, while in-house R&D does not play a significant role.  相似文献

A lot of researches have shown that geographic proximity and technological proximity influence firms’ innovative performance. Little work has been done to explore how technological proximity interacts with geographic proximity. Using the theories of recombinant innovation and economic geography, this study develops and tests a theory of how firms’ abilities to reap local benefits and generate innovation are influenced by technological features. Data on technological and geographic proximity of the top 100 firms in China’s electronics industry from 1985 to 2012 are used to test the hypotheses. This study shows that, for a firm with high geographic proximity or located in a dense area of R&D, a low technological proximity in the industry facilitates the process of recombinant innovation.  相似文献

The aim of the paper is to examine the relationship between R&D capital and productivity using microdata for Danish manufacturing firms. The influence of factors such as ownership, innovative characteristics and source of funding accounted for. The return to accumulated R&D capital is estimated to be in the neighbourhood of 9–12%, whereas the short-run effect of R&D is insignificant. Furthermore, the direct influence from foreign ownership, source of funding accounted for, innovative characteristics and ownership dispersion on productivity are analysed. However, none of the factors seem to have an impact on firm productivity. The same is the case for the indirect influence coming from interaction with accumulated R&D capital.  相似文献

In this paper, we examine the trade off between different effects of the availability of venture capital on the speed of technological progress in an industry. We consider an evolutionary industry simulation model based on Nelson and Winter (1982), in which R&D efforts of an incumbent firm generate technological know-how embodied in key R&D employees, who might use this know-how to found a spinoff of the incumbent. Venture capital is needed to finance a spinoff, so that the expected profits from founding a spinoff depend on how easily venture capital can be acquired. Accordingly, thick venture capital markets might have two opposing effects. First, incentives of firms to invest in R&D might be reduced and, second, if spinoff formation results in technological spillovers between the parent firm and the spinoffs, the generation of spinoff firms might positively influence the future efficiency of the incumbent’s innovation efforts. We study the manner in which this tradeoff influences the effect of venture capital on innovation expenditures, speed of technological change and evolution of industry concentration in several scenarios with different industry characteristics.  相似文献

This paper derives a simple, but informative, model of firm R&D to figure out key factors that determine firm R&D effort. The model suggests a demand-pull, technology-push theory of R&D by showing that a firm's profit-maximizing R&D expenditure is determined jointly by both demand-side factors and technology-side factors. The former includes demand size (firm sales) and consumer preference over quality and price and the latter includes R&D cost structure or the production-cost effect of product R&D and firm-specific technological competence. In addition, the model shows that other things being equal, the stock of exogenous technological knowledge, including the firm's previously accumulated technological knowledge, relevant to current R&D which is negatively related with current R&D effort. An empirical analysis of firm R&D intensities and technological capabilities of more than 1600 firms in nine industries across six countries provides supportive evidence for the theory. Further, the theory implies that R&D intensity or the R&D-to-sales ratio is independent of firm size unless firm size affects technological competence and that given consumer preference and R&D cost structure facing all firms in the same industry, the distribution of firm-specific technological competence among firms determines the distribution of firm R&D intensities within the industry.  相似文献

ABSTRACT

This paper applies a linear Bayesian regression model to study the effects of economic policy uncertainty (EPU) and Chief Executive Officer (CEO) characteristics on firm Research and Development (R&D) expenditure. We specifically analysed data from 1,163 Chinese companies listed as A-shares from 2008–2016. EPU is believed to curtail firm investments as it causes unexpected market conditions. Yet, our findings obtained with Bayesian analysis show a positive relationship between EPU and firm R&D expenditure. Specifically, we found that some CEO attributes (e.g., age, tenure and marketing/sales experience) led to a negative relationship between EPU and firm R&D expenditure, whereas other attributes (e.g., education, overseas study/work experience, product R&D experience, and process engineering experience) lead to a positive relationship. Our findings provide nuanced insights into how different CEO characteristics influence firms’ R&D expenditure in a context of uncertainty.  相似文献

In this paper a firm’s R&D strategy is assumed to be endogenous and allowed to depend on both internal firm characteristics and external factors. Firms choose between two strategies, either they engage in R&D or abstain from own R&D and imitate the outcomes of innovators. This yields three types of equilibria, in which either all firms innovate, some firms innovate and others imitate, or no firm innovates. Firms’ equilibrium strategies crucially depend on external factors. We find that the efficiency of intellectual property rights protection positively affects firms’ incentives to engage in R&D, while excessive competitive pressure has a negative effect. In addition, smaller firms are found to be more likely to become imitators when the product is homogeneous and the level of spillovers is high. Regarding social welfare our results indicate that strengthening intellectual property protection can have an ambiguous effect. In markets characterized by a high rate of innovation a reduction of intellectual property rights protection can discourage innovative performance substantially. However, a reduction of patent protection can also increase social welfare because it may induce imitation. This indicates that policy issues such as the optimal length and breadth of patent protection cannot be resolved without taking into account specific market and firm characteristics.  相似文献

This study focuses on how the business type and technological learning mode, which a high-tech firm chooses based on its core competence, influence the firm's R&D strategies, which in turn affect firm performance. This study also explores how the interaction between a firm's business type and industry value chain stage affects the relationship between R&D investments and operating performance. We suggest that the linkage of R&D investments and operating performance will increase gradually, when firms move from contract manufacturing to own brand business. R&D investments can contribute more to performance when firms adopt the hybrid business type. Furthermore, R&D investments generate more significant benefits for the own brand companies than the contract manufacturers at the same stage of the industry value chain. R&D investments of the downstream contract manufacturers have a negative impact on firm performance. Regardless of business type, firms in the upstream (midstream) stage of the industry value chain outperform downstream stage firms in deriving benefits from R&D activities. Finally, the lagged effects of R&D investments on operating performance are affected by the interaction between business type and industry value chain.  相似文献

We provide evidence that both human capital and R&D increase the likelihood that a firm will be a high-growth firm in the industry. However, different from human capital, being an R&D active firm also increases the probability of substantial decline or failure, underscoring the risky nature of innovation. Quantile regression results show that, different from R&D, human capital is growth-enhancing for all firms, hence also those located in the lower quantiles of the distribution of growth rates across firms.  相似文献

Based on the knowledge-based view of the firm, this paper analyses how alternative configurations of technological relatedness in interfirm research and development (R&D) alliances influence specific types of product innovation. A longitudinal study of pharmaceutical firms provides support for the argument that complementary alliances contribute to the development of both radical and incremental innovation. Collaborating with partners that have similar technologies only enhances incremental innovation, although its impact is curvilinear. These evidences highlight the importance of designing a suitable portfolio of R&D alliances in order to develop different innovative competences.  相似文献

This paper employs individual firm data in order to check the existence of industry-spatial effects alongside other microeconomic determinants of R&D investment. Spatial proximity is defined by a measure of firms’ industry distance based on trade intensity between sectors. The spatial model specified here refers to the combined spatial-autoregressive model with autoregressive disturbances. In modelling the outcome for each location as dependent on a weighted average of the outcomes of other locations, outcomes are determined simultaneously. The results of the spatial estimation suggest that in their R&D decision firms benefit from spillovers originating from neighbouring industries.  相似文献

In this paper we study an industry in which there is an ongoing sequence of R&D races between two firms. Firms are engaged in product innovation. Products are horizontally and vertically differentiated. There are two key characteristics/dimensions to products, and the level at which these are embodied in products can be increased by R&D. At each time firms can spend R&D on improving their product in one or both dimensions. We allow the possibility of economies scope — so R&D undertaken in one dimension can spillover to the other. The question we are interested in is whether a firm that is ahead in a single dimension but behind in another will focus all its R&D effort in the area in which it is ahead (product specialisation), or whether it will try to do R&D in both dimensions in the hope that it might get ahead in both and end up with a superproduct that dominates in both characteristics. The outcome of this R&D competition determines a Markov transition probability matrix determining the evolution of the industry. We show that when the R&D technology is characterized by constant returns then the only steady-state outcome is one in which the economy stays forever in a position in which one firm produces a super-product and the other gives up doing R&D altogether. This outcome is unaffected by the degree of economies of scope. When the R&D technology is characterised by decreasing returns, then the industry will visit all states and so will exhibit both product specialisation and superproduct dominance at various times. Now the extent of economies of scope matters and we show that the greater the extent of economies of scope, the less likely is the industry to exhibit product dominance, and the more likely it is to exhibit product specialisation.  相似文献
