This paper studies vertical R&D spillovers between upstream and downstream firms. The model incorporates two vertically related industries, with horizontal spillovers within each industry and vertical spillovers between the two industries. Four types of R&D cooperation are studied: no cooperation, horizontal cooperation, vertical cooperation, and simultaneous horizontal and vertical cooperation. Vertical spillovers always increase R&D and welfare, while horizontal spillovers may increase or decrease them. The comparison of cooperative settings in terms of R&D shows that no setting uniformly dominates the others. Which type of cooperation yields more R&D depends on horizontal and vertical spillovers, and market structure. The ranking of cooperative structures hinges on the signs and magnitudes of three \"competitive externalities\" (vertical, horizontal, and diagonal) which capture the effect of the R&D of a firm on the profits of other firms. One of the basic results of the strategic investment literature is that cooperation between competitors decreases R&D when horizontal spillovers are low; the model shows that this result does not necessarily hold when vertical spillovers are sufficiently high, and/or when horizontal cooperation is combined with vertical cooperation. 相似文献

Multinational enterprises and innovation: firm level evidence on spillover via R&D collaboration 总被引:1,自引:0,他引:1

This paper estimates the knowledge spillovers to multinational enterprises (MNEs) in Sweden via domestic and foreign R&;D collaboration.
Applying an augmented generalized method of moments-estimator that accounts for selectivity and simultaneity bias on data
from 1,249 MNEs, our research has resulted in five distinct conclusions. First, we find that the knowledge spillovers via
R&;D collaboration typically take place as a network phenomenon rather than a process between the local firm and a single innovation
partner. Second, successful collaboration is conditional on the presence of foreign innovation partners in the network. Third,
output is found to be an increasing function of R&;D-collaboration only among non-export oriented firms. Fourth, foreign MNEs,
selling mainly to local and regional markets in Sweden, benefit more from R&;D collaboration than do other firms. Overall,
the results show that demand-driven motives that require entrepreneurial knowledge to adapt products to local consumers and
markets are more important for successful R&;D-collaboration than supply-driven motives. 相似文献

Innovation and the competitiveness of industries: Comparing the mainstream and the evolutionary approaches 总被引:1,自引:0,他引:1

The study of the relationships between innovation and the competitiveness of industries is an important topic for both, academic research and economic policy. The huge economics literature flourished in the last couple of decades on the subject broadly falls into two distinct research traditions, namely the mainstream R&D spillovers approach and the evolutionary economics view. Both traditions agree on the important role played by innovation and the inter-sectoral diffusion of advanced knowledge for the competitive performance of industrial sectors. Behind this general agreement, however, the two approaches are radically different. This paper shows that, at a deeper level of analysis, the mainstream and evolutionary views do indeed differ with respect to their theoretical foundations, empirical research and policy implications. In a nutshell, while the mainstream R&D spillover approach is inspired by a traditional view of economic policy based on a market-oriented approach, the evolutionary view is on the contrary consistent with the idea that institutional arrangements and policy interventions do indeed play a fundamental role for shaping innovation patterns and their impacts on the competitiveness of industries. 相似文献

This article analyzes cost-reducing R&D investments by firms that behave non-cooperatively or cooperatively. Firms face a trade-off between allocating their R&D investments to innovate or to imitate (absorb). We find that the non-cooperative behavior not only induces more imitation (absorption) but also, for the most part, more innovation investments. Only the cooperative behavior, however, ensures that R&D investments are allocated efficiently to innovation and to imitation (absorption) in the sense that any given amount of industry-wide cost reduction is obtained for the minimum overall R&D costs. 相似文献

This paper computes private and social rates of return to R&D capital in the three vertically linked sectors, primary agriculture, food processing, and the farm machinery in the United States. Using a cost function approach, the private rates of return to R&D ranged from an average of 21.5% per annum for farm machinery to 87.5% for agriculture. The social rates of return to R&D in food processing and farm machinery are larger than the private rates due to spillovers. We find that spillovers from public agricultural R&D mitigates the market's failure in farm machinery to fully appropriate the returns to its R&D capital. 相似文献

We analyse the effects of network externalities in strategic R&D competition. We present a model of two firms competing with R&D investments and prices in a differentiated consumer market. Buyers form firm-specific networks which can be compatible. A high degree of compatibility and large spillovers moderate price competition due to weak strategic value of firm-specific networks and R&D investments, respectively. Asymmetry in product qualities brings out network effects that cancel out in conventional symmetric settings. The lower quality firm increases R&D and decreases its price as spillovers or network compatibility is increased. This happens when R&D and firm-specific network size have high strategic value. 相似文献

We analyse both the theoretical and the empirical side of the issue of R&D spillovers. Each firm's R&D costs are increasing in the amount of information transmitted to other firms, and we account for the possibility that firms control spillovers. We consider both Cournot-Nash and Cournot-Stackelberg behavior. The empirical analysis suggests that (i) firms' control on spillovers is relatively low; (ii) the cost-saving effect associated to joint ventures or R&D cartels is confirmed for industries where firms rely mainly upon own R&D as a source of innovation; (iii) R&D cooperation may increase information sharing, thereby enhancing spillovers. 相似文献

The model studies information sharing and the stability of cooperation in cost reducing Research Joint Ventures (RJVs). In a three-stage game-theoretic framework, firms decide on participation in a RJV, information sharing along with R&D expenditures, and output. An important feature of the model is that voluntary information sharing between cooperating firms increases information leakage from the RJV to outsiders. It is found that RJVs representing a larger portion of firms in the industry are more likely to share information. It is also found that when sharing information is costless, firms generally don't choose intermediate levels of information sharing: they share all the information or none at all. The size of the RJV is found to depend on three effects: a coordination effect, an information sharing effect, and a competition effect. Depending on the relative magnitudes of these effects, the size of the RJV may increase or decrease with spillovers. In response to an increase in leakages, RJV members reduce their R&D spending. In addition, they either increase the RJV size while maintaining information sharing unchanged (when leakages are low), or they reduce both information sharing and RJV size (when leakages are high). 相似文献

The paper presents a novel tax that is designed to improve the performance of research and development (R&D) investments. Ideally, the tax allows the technical efficiencies of monopoly while bringing about the desirable effects of the competitive pressure of R&D rivalry. Thus, with the tax, the state can sanction a monopoly of R&D investment in order to attain technical efficiencies and yet avoid the underinvestment in R&D that would result without competitive pressures. A critique of the tax emphasizes the problems of implementing it and offers a more practical alternative that would achieve the same desirable effects. 相似文献

R&D and productivity: Internal vs. external R&D - evidence from west german manufacturing industries
Werner Bönte 《Economics of Innovation and New Technology》2013,22(4):343-360
The paper explores the productivity effects of investment in external (contract) vs. internal (in-house) R&D in a sample of West-German Manufacturing Industries. The results provide strong evidence of a positive relationship between productivity and the share of external R&D in total R&D. This result is robust to alternative econometric specifications. Thus, findings suggest that the decision between internal and external R&D does matter. Moreover, results imply a nonlinear relationship between productivity and the share of external R&D for higher-technology industries, hinting at decreasing productivity effects of an increasing share of external in total R&D. 相似文献

This paper has three novelties. First, we argue that any given R&D facility’s capacity to exploit and/or augment technological competences is a function not just of its own resources, but the efficiency with which it can utilise complementary resources associated with the relevant local innovation system. Just as asset-augmenting activities require proximity to the economic units (and thus the innovation system) from which they seek to learn, asset-exploiting activities draw from the parent’s technological resources as well as from the other assets of the home location’s innovation system. Furthermore, we argue that most firms tend to undertake both asset exploiting and augmenting activities simultaneously. Second, we use patent citation data from the European Patent Office to quantify the relative asset augmenting vs. exploiting character of foreign-located R&D. Third, we do so for European MNEs located in the US, as well as US MNEs located in Europe. Our results indicate that both EU (US) affiliates in the US (EU) rely extensively on home region knowledge sources, although they appear to exploit the host country knowledge base as well. 相似文献

Cooperation and the efficiency of regional R&D activities 总被引:7,自引:0,他引:7
This paper investigates the relationship between the cooperativebehaviour of manufacturing establishments in a region and theefficiency of their R&D activities, using data for 11 Europeanregions. Some significant differences in the attitude towardsR&D cooperation as well as with regard to the efficiencyof R&D activities between the regions can be found. However,these two issues appear to a large degree to be empiricallyunrelated. Therefore, the role of R&D cooperation in regionalinnovation systems remains unclear. 相似文献

ABSTRACTFollowing the evolutionist and neo-schumpeterian approach and the literature on additionality of innovation policy, this paper evaluates the impact of public funding to innovation on the intensity of the R&D expenditures and on the intensity of the employment in innovation. The analysis is based on recent evidence of Argentine manufacturing firms surveyed by ENDEI for 2010–2012 using Propensity Score Matching (PSM) method. The results show a positive impact on the intensity of the R&D effort of the supported firms in monetary terms, allowing us to reject the full crowding-out hypothesis. However, the positive monetary impact is not accompanied by a greater proportion of employment oriented to innovation activities, neither formal nor informal; so it is not possible to conclude that the analyzed policy translates into an improvement in the innovation competencies of the firms based on this indicator. 相似文献

A model is developed of the relation between adoption of an innovation by firms and firm size. Decision making is represented as a group assessment of the perceived ratio between expected returns after succesful introduction, and the risk that implementation will fail or will last too long to makc adoption worth while. In view of differences in thc assessment of uncertainty and corresponding demands on the perceived return-to-risk ratio, among influencers of decisions in the firm, decision making is taken as stochastic, with a probability of adoption related to (objective) net benefits, and probability of non-adoption related to risk. The model gives a new way of looking at the fact that small firms lag behind in the adoption of new technology. In contrast with previous models proposed by David and Davies the explanation has nothing to do with there being some critical size below which adoption is not profitable. The present model explains the adoption lag for smaller firms as the result of expected returns being proportional to size while risk of failed implementation is independent of size. The model is tested and estimated empirically on data for the adoption of computers in small scale retailing, in the Netherlands. 相似文献

This paper measures the cumulative change in research and development (R&D) efficiency of globally leading R&D companies in the technology industry. We use Data Envelopment Analysis /Malmquist index to analyse 49 such companies. The change in R&D efficiency is analysed by decomposing the Malmquist index into ‘catch-up’ and ‘frontier shift’ indices, and by comparing cumulative indices to those at the starting period. Those cumulative indices are obtained at both a firm and an industry level. Results indicate that the overall R&D efficiency of these globally leading R&D companies declined slightly during the period 2007–2013. At a firm level, this study determines in detail how the trend of each firm in R&D activities differs from other companies. 相似文献

This paper analyzes the evolution and role of corporate entrepreneurship in Swedish industry, particularly for the 1945–1980 period, based on data on the 100 economically most important innovations during this period. Privately owned large corporations (Schumpeter Mark II) dominated in launching innovations in almost all industrial sectors and in all subperiods but decreasingly so. 20% of the innovations were launched by new firms (Schumpeter Mark I) but most of these new firms were spun-off and/or acquired by large corporations. State entrepreneurship was marginal. Universities played an important role, although sector-specific. New firms and existing firms had similar growth rates and almost identical and short gestation times to international markets for their innovations. 80% of the corporate innovations were product renewals rather than product diversifications or process innovations. No evidence of an evolution from autonomous over corporate to state entrepreneurship, as hypothesized by Schumpeter, was found. Evolution of a dynamic coexistence of. these forms of entrepreneurship is hypothesized in this paper. The paper finally presents a model, synthesizing Schumpeter Mark I and II, for analyzing technological change and entrepreneurship. 相似文献

This paper employs the logit model to explore the relationship between internationalization and its determinants. Using a sample set gathered from 114 high technology firms of Taiwan, which are mostly engaged in original equipment manufacturing, empirical tests of the hypotheses find support that corporate governance, patent counts, and education level of managers had a positive effect on internationalization. Surprisingly, R&D intensity, one of the innovation capitals, had a negative effect on internationalization. 相似文献

This paper analyses the relationship between OECD countries'business sector total factor productivity and domestic and foreignR&D efforts during the period 1961-1991. A sensitivity analysisis performed by making use of alternate estimations of specificationsin growth terms and in level terms. The results are shown tobe robust. They show that the influence of international technologicaldiffusion is, on average, substantially stronger than that ofdomestic R&D. In the case of the large economies, however,the latter influence is found to be more important. A structuralstability analysis provides evidence of a decrease in the estimatesin the mid-1970s, without significant recovery afterwards. Variouslong-run supply effects appear to have contributed. The discontinuousnature of the reduction does indicate, however, that these werereinforced by macroeconomic disturbances at the demand side. 相似文献

ABSTRACTUsing a vector-error-correction model (VECM) with total factor productivity (TFP), domestic and foreign research and development investment (R&D) as well as GDP, we find that for the Netherlands for the period 1968–2014, extra investment in public and private R&D has a clear positive effect on TFP growth and GDP. Taking into account the costs of these extra investments, we find that the rate of return to such a policy is positive and high. We also find dynamic complementarity of public and private stocks of R&D for a long period after the initial shock. However, our results also show that the productivity effects on the Dutch economy are weaker when they are part of an internationally concerted policy effort, i.e. when other OECD countries implement policies with the same effects on R&D stocks in their countries. While complements in the long run equations of the model, in the adjustment process Dutch domestic private R&D appears to consider foreign public R&D as a substitute, i.e. when foreign public R&D rises, Dutch private R&D tends to shrink. 相似文献
