This paper considers the Goyal and Moraga‐Gonzalez (2001 ) model of strategic R&D collaboration networks in the open economy framework. The R&D is the d'Aspremont and Jacquemin (1988 ) process innovation and collaboration takes the form of research joint ventures (RJV) in which firms cooperate in R&D but compete in product markets. Countries decide whether to establish free‐trade links while firms decide whether and with whom to form RJVs. A double‐layer pairwise stability concept is introduced to characterize equilibrium network structures. In contrast with conventional wisdom, it is shown that global free trade generally reduces collaborative R&D levels. We give conditions for which pairwise stable R&D networks are welfare maximizing. Stability and efficiency are congruent when R&D cost is either too high or too low. A large public spillover effect is detrimental to an R&D network when trade networks are regional.  相似文献

This study analyzes the optimal product R&D investment policies of a developed and a developing country in an international Cournot duopoly where firms from these two countries compete through endogenous quality–quantity decisions. We explore a new international trade model by using demand functions derived from utility functions. We find that the optimal product R&D investment policies for both countries are subsidies. This study counters a finding that used Hotelling‐type demand functions and it partially modifies another result that adopted the same demand functions but with an international Bertrand duopoly.  相似文献

We consider a two-stage game with firms investing in R&D in the first stage while competing [a] la Cournot in the second stage. The firms are located in two countries, which are either segmented or integrated. R&D spillovers occur between firms located in the same country as well as between firms located in different countries.

We first examine the consequences of market integration on the impact of national and international R&D spillovers on innovative efforts, effective R&D, profits and total welfare. Comparing the resulting equilibrium levels, we subsequently conclude that market integration always leads to higher R&D investments and output if international R&D spillovers are limited, while the welfare consequences are ambiguous. Finally, we also analyze the welfare maximization problem of a ‘constrained social planner who can only decide on the level of R&D spillovers.  相似文献

We analyze the role of international market size differences in determining the investment in process R&D (and thus firms?? competitiveness) in a trade model with oligopolistic market structure, non-homothetic production technology and costly trade. We show that the R&D effort is higher (or even disproportionately so) for firms in the larger market, which causes endogenous asymmetries across countries. As a result, firms in the larger market have higher competitiveness, which increases their market shares in international markets. Furthermore, and contrary to what is predicted by Krugman (Am Econ Rev 70:950?C959, 1980) ??home market effect??, in equilibrium the larger country does not need to host a disproportionately higher share of the world??s industry than of the world??s demand. Despite this, the larger country can still continue to run a trade surplus in the oligopolistic sector, since it hosts firms with higher competitiveness than firms in the smaller country.  相似文献

With the rapid pace of economic integration, the productivity of a country depends not only on domestic R&D, but also on foreign R&D through technology diffusion across countries. The advancement of information technology (IT) has made the international transmission of knowledge faster and more efficient, providing an important channel for international R&D spillovers. This paper investigates three channels of international R&D spillovers: trade, FDI, and information technology. Applying panel cointegration and dynamic OLS analysis to the data for 21 OECD countries plus Israel during the period from 1981 to 1998, we find that bilateral trade remains an important conduit for international R&D spillovers. Although bilateral FDI is found to be positively related to international R&D spillovers, their impact on productivity growth is relatively small. We also find that the development of information technology has played a more important role in international R&D spillovers and productivity growth in recent years.  相似文献

This paper examines the standard symmetric two‐period R&D model with a deterministic one‐way spillover structure: know‐how flows only from the high R&D firm to the low R&D firm (but not vice versa). Though firms are ex ante identical, one obtains a unique asymmetric equilibrium (pair) in R&D investments, leading to interfirm heterogeneity in the industry. R&D cooperation by means of a joint lab is considered and compared to the non cooperative solution. The main part of the paper provides a second‐best welfare analysis in which we show that the joint lab yields a socially optimal R&D level subject to an equal treatment (of firms) constraint, which also coincides with the noncooperative solution in the absence of spillovers. We also investigate the welfare costs of this equal treatment constraint and find that they can be quite significant.  相似文献

海外研发被视为后发国家实现技术赶超的有效路径,现有文献基于经贸自由化的前置条件证实了海外研发提升创新绩效的反哺作用。然而在全球贸易保护主义抬头的背景下,资源要素的自由流动愈发困难,海外研发能否发挥应有的作用尚不得而知。为此,基于中国高科技上市公司的数据,本文探索了中美贸易摩擦如何影响中国企业的海外研发绩效。研究发现,中美贸易摩擦非但没有侵蚀中国企业的海外研发绩效,反而产生倒逼效应,推动中国企业提升投资效率并积累国际投资经验,继而增强了海外研发的反哺作用。通过区分海外研发目的地,本文进一步发现倒逼效应在赴非美国家的样本中更显著。赴美研发受到贸易摩擦的冲击更为直接,稀释了提升投资效率和积累国际化经验所带来的收益。研究结论深化了国际商务理论关于贸易保护和壁垒如何影响跨国企业投资绩效的相关研究,为中国企业在高度不确定的投资环境下如何充分释放海外研发的潜能提供启示。  相似文献

We investigate the imposition of a horizontal technical barrier to trade (HTBT) in a symmetric, cross‐hauling duopoly. Tariffs and subsidies are ruled out, but, in the absence of a mutual recognition agreement, governments can impose HTBTs, so long as firms operate different technologies. With firms being first movers, this possibility may induce them to avoid technical collaboration, in order to tempt governments into creating national monopolies, unless spillovers in R&D are high. This exacerbates the costs of regulatory protection, compared to standard models without R&D or spillovers.  相似文献

This study analyzes marginal social and private returns of R&D investment through the impact of international spillovers of R&D stocks. We compare the marginal social with marginal private returns using data of 27 OECD and EU countries from 1995 to 2008. We consider two channels of R&D spillovers: embodied in trade flows and disembodied by bilateral technological proximity. We find that marginal social returns on R&D are much larger than the marginal private returns for R&D‐intensive countries, in the embodied spillover channel. We also find that the embodied spillover channel through import flows is more important than the disembodied channel.  相似文献

This article investigates the relationship between firm’s R&D intensity, expressed as R&D expenditure over sales, and investment intensity in tangible assets. It is commonly acknowledged that R&D requires additional physical investment to be implemented. R&D increases a firm’s productivity and return to tangible investments, thus, providing to the firm incentives to bear high tangible capital costs and to invest more. This represents a crucial issue for a firm’s growth, particularly considering the strong interaction between physical capital accumulation and technological progress. The analysis is based on a large sample of manufacturing firms across seven European countries in the period 2007–2009. Since the sub-sample of firms performing R&D might not be random, there may potentially be an endogeneity issue. The analysis also considers that firms may decide to spend on R&D and investment in physical capital simultaneously. The questions of both endogeneity and simultaneity are dealt with by employing an instrumental variable two-step procedure. We find a positive and significant impact of R&D intensity on firms’ tangible investment intensity. The econometric results highlight the importance of financial factors, particularly with respect to firms’ internal resources. Exposure to international trade has a negative impact on investment, possibly depending on the time-span of the sample used.

Cooperation vs. competition in R&D: The role of stability of equilibrium   总被引:3,自引:0,他引:3  
We consider a model in which firms first choose process R&D expenditures and then compete in an output market. We show the symmetric equilibrium under R&D competition is sometimes unstable, in which case two asymmetric equilibria must also exist. For the latter, we find, in contrast to the literature that total profits are sometimes higher with R&D competition than with research joint venture cartelization (due to the cost asymmetry of the resulting duopoly in the noncooperative case). Furthermore, these equilibria provide another instance of R&D-induced firm heterogeneity.  相似文献

We study an international climate agreement that assigns emission quotas to each participating country. Unlike the simplest models in the literature, we assume that abatement costs are affected by R&D activities undertaken in all firms in all countries, i.e. abatement technologies are endogenous. In line with the Kyoto agreement we assume that the international climate agreement does not include R&D policies. We show that for a second-best agreement with heterogeneous countries, marginal costs of abatement differ across countries. In other words, the second-best outcome cannot be achieved if emission quotas are tradable.  相似文献

We use a combination of theory and experiment to study the incentives for firms to share knowledge when they engage in research and development (R&D) in an uncertain environment. We consider both symmetric and asymmetric starting points with regards to the amount of initial knowledge firms have before conducting R&D and look at how differences in starting positions affect the willingness of firms to share knowledge. We investigate when and if firms find R&D cooperation beneficial and how investment in R&D is affected by the outcome of the sharing decisions. The experimental evidence shows that overall subjects tend to behave consistently with theoretical predictions for the sharing of knowledge, although leaders who are not compensated by a side payment from laggards are more willing to share than predicted by the theory, and leaders who are compensated are less willing. The data on investment suggests less investment with sharing than without, consistent with theory. Compared to exact numerical predictions, there is overinvestment or underinvestment except for symmetric firms under no sharing. All cases of overinvestment and underinvestment, regardless of sharing or not and regardless of starting positions, are well explained by smoothed-out best (quantal) responses.  相似文献

ABSTRACT

This paper investigates the determinants of university-industry links in five European countries (France, Germany, Italy, Spain and the UK), using internationally comparable firm-level data for the period 2007–2009. Besides the usual firm-specific variables, it examines the role of meritocratic management practices in firms’ decisions to collaborate in R&D. Firm innovative efforts, the export status and the R&D government support are positively related to business-university links in almost all countries, human capital and firms’ size in two out of five countries under scrutiny, while belonging to science-based sectors does not seem to play a significant role in all countries but Italy. Importantly, we find that meritocratic managerial practices positively affect the firm-university nexus in Germany, France and the UK, while meritocracy does not appear to enhance businesses’ R&D collaboration in Italy and in Spain.  相似文献

This paper attempts to implement empirically a Schumpeterian model of international trade. After briefly discussing the literature on trade and technology, we formulate a model in which ‘real’ factors such as R&D expenditures, investment and wage costs have an impact on bilateral trade flows between advanced economies. We also take into account the effect of exchange rate differences. The model is empirically estimated on sectoral data for nine OECD countries. We find that what determines competitiveness differs by sector. In many sectors, either R&D expenditures or wage costs are important. The results for investment indicate a weaker role. Consistent with the Marshall-Lerner logic, we find that the sign of exchange rate changes varies by sector. We conclude the paper by a discussion of the relevance of the results for ‘technology-based’ theories of international trade.  相似文献

The paper considers the role of technology diffusion and trade liberalization for the catching‐up of structurally backward countries. A New Economic Geography model is presented that accounts for firm entry/exit and international mobility of skilled labor employed in public R&D sectors. This raises the traditional agglomeration effects in a core–periphery setting as firms and mobile factors usually cluster within spatial agglomerations. With international technology diffusion, however, there is a counteracting effect on the traditional agglomeration effects as firms in the periphery also benefit from increasing R&D expenditures in the core lowering entry costs for firms. It is found that the catching‐up of structurally backward countries is spurred not only as a result of trade integration but also because of technology diffusion.  相似文献

国际贸易、R&D溢出和生产率增长   总被引:108,自引:4,他引:108  
本文采用6种计算外国R&D资本的方法和国际R&D溢出回归方法,首次就国际R&D溢出对中国工业行业的技术进步增长、技术效率增长和全要素生产率增长的影响作了实证分析。我们从这6种方法的比较中发现:当采用有缺陷的两种方法时,得到国际R&D溢出系数显著为负或者溢出系数为正,但不显著的结论;而采用其他的四种方法,能得到国际R&D溢出系数显著为正的结论。因此,从计算方法本身及其结论的比较来看,通过国际贸易渠道的R&D溢出促进了中国工业行业的技术进步、技术效率及全要素生产率增长的结论更可靠。同时发现在大部分情况下国内本行业R&D与其他行业R&D对行业技术进步、技术效率和全要素生产率的增长起阻碍作用。因此,加强与R&D投入比重较高的发达国家的国际贸易以及提高国内自身的R&D效率显得很有必要。  相似文献

The implications of international R&D competition on trade and growth are investigated. The model is one in which a separate R&D sector competes with the manufacturing sector to secure human capital, and technology is licensed to manufacturers by the winner of a pre-emptive R&D competition. The results show that globalization of R&D competition leads to trade between countries (even identical countries), because the result of competition leads to a reallocation of human capital between sectors. The winning country exports technology and traditional goods, while the loser exports manufactured goods. Globalization with indiscriminate technology licensing increases the world's economic growth rate.  相似文献

As developing countries open themselves up to trade, many industrial firms in these countries are finding it difficult to compete internationally due to poor product quality and low product variety. Although China has been the largest producer of crude steel since 1996, China's steel firms have produced an overabundance of low-quality steel while domestic purchasers of steel have increasingly demanded higher quality steel products. Many have argued that for Chinese steel firms to improve product quality they must adopt more advanced technologies. Employing firm-level panel data of steel firms in China, we econometrically test the relative importance of two possible sets of factors affecting a firm's ability to utilize technology to improve product quality: technology acquisition factors and technology absorptive capacity factors. We find that technology complements such as in-house R&D and foreign knowledge must be combined with technology for Chinese firms to improve product quality.  相似文献

Using firm-level R&D data with regional international talent data, we find that international talent increases the R&D investment of Chinese manufacturing firms, a result that is further confirmed with patent data and under a number of robustness checks. These findings stem from two mechanisms: international talent boosts human capital accumulation and provides a diversified labor force. Further, the R&D promoting effect is stronger if firms are located in eastern China rather than in other regions, of small and medium-sized rather than large-sized, of domestic ownership rather than foreign ownership. The policy implication is, the introduction of international talent can be a new way to promoting R&D investment, especially for skilled-labor constrained countries.  相似文献
