This paper empirically investigates the impact of different channels for international technology spillover on the innovation performance of Chinese high-tech industries, using panel data analysis. We report that learning-by-exporting (and importing) promotes innovation in Chinese indigenous firms. Foreign R&D activities by multinational enterprises in a host country significantly affect the innovation performance of domestic firms only when absorptive ability is taken into account. The findings indicate that both international technology spillover sources and indigenous efforts jointly determine the innovation performance of Chinese high-tech sectors.  相似文献

One of the benefits claimed for investment in Research and Development (R&D) is that there is a spillover effect. Industries benefit from both their own R&D efforts as well as the efforts of other national and overseas industries. The present research presents new evidence on the long-term impact of R&D investment upon UK industry's productivity performance and on the nature of these “R&D spillovers”. The results suggest that R&D efforts from the industry itself and from other national industries have a positive impact on the industry's productivity but, interestingly, there is no gain from foreign R&D investment.  相似文献

We model how R&D enters the innovation system in four ways (intramural, extramural, cooperative, and spillover). Despite measuring three different spillovers together, for a very large sample of European enterprises we conclude that the productivity effects of spillovers were at best smaller than intramural R&D productivity effects. We also find that building on the greater skills and experience of enterprises already undertaking R&D (intensity) raised labour productivity more than providing support for those beginning R&D (extensity). Optimal extramural R&D intensity was higher than the actual level; sample firms could boost productivity either by abandoning extramural R&D or by doing much more. There were substantial differences in our sample between enterprises and countries in terms of R&D spillovers. Greater multinational corporation incidence in new EU members accounted for these countries' high direct R&D intensity productivity, regardless of their generally low overall labour productivity. Absorptive capacity made little difference to the utilisation of spillovers.  相似文献

This study explores the channels through which technological investments affect productivity performance of industrialized economies. Using a Stochastic Frontier Model (SFM) we estimate the productivity effects of R&D and ICT for a large sample of OECD industries between 1973 and 2007, identifying four channels of transmission: input accumulation, technological change, technical efficiency and spillovers. Our results show that ICT has been particularly effective in reducing production inefficiency and in generating inter-industry spillovers, while R&D has raised the rate of technical change and favoured knowledge spillovers within sectors. We also quantify the contribution of technological investments to output and total factor productivity growth documenting that R&D and ICT accounted for almost 95% of productivity growth in the OECD area.  相似文献

The aim of the paper is to investigate in a simultaneous equation framework the role of R&D cooperation in the innovation process—in context with other factors—from two specific aspects. First, analysis focuses on the impact of R&D cooperation on firms’ innovation input and output. Second, analysis is undertaken as to how the number of cooperation partners affects the innovation behaviour of firms. Starting with the discussion of theoretically expected effects of successful R&D cooperation on the innovation activities of firms, the importance of inter-organizational arrangements in R&D is empirically investigated in respect of firms in the German manufacturing industry. The estimation results can be summarized as follows: joint R&D is used to complement internal resources in the innovation process, enhancing the innovation input and output measured by the intensity of in-house R&D or the realization of product innovations. On the input side, the intensity of in-house R&D also stimulates the probability and the number of joint R&D activities with other firms and institutions significantly.  相似文献

Global productivity growth has either stagnated or declined, despite continued technological innovations with the rise of knowledge-intensive intangibles that arise from the growth of knowledge stock (R&D activities). Understanding the root causes of this paradox in the context of growing economies requires an investigation of whether local knowledge diffusion can explain firm-level productivity differences, including key constraining factors like sources of financing or corporate governance structure. Using financial data of 7970 Indian firms over a 20-year period and clustering firms across industries, we assess the impact of R&D stock that is external to the firm through estimating both within (intra) and between (inter) industry spillovers. We find that both R&D and non-R&D-performing firms benefit from ‘between industry’ spillovers. We further show that firms with better access to finance achieve higher productivity, not only through their own R&D capital stock but also via both types of industry-level knowledge spillover. We allow for the two key sources of international spillovers namely import intensity and FDI. While import-intensive firms experience lower productivity, FDI mitigates this adverse productivity effect across knowledge-intensive exporting firms. The paper concludes that financially unconstrained firms and firms with greater corporate board connectedness derive positive industry-level spillover effects, reflecting intra- and inter-industry as domestic spillover or local value-chain effect in the literature on technological innovation.  相似文献

      基于中国汽车制造业2001~2012年的数据,根据分布滞后(ADL)模型和库伊克模型的思想,以AIC、SC信息准则为标准选择最优滞后阶数,研究加入滞后效应考量的情况下,FDI、R&D对中国汽车制造业技术创新能力的影响。研究表明:FDI对中国汽车制造业技术创新能力的影响随着时间累积整体表现出增强趋势,即存在滞后效应,且主要体现为对创新竞争力的正向影响较显著,对核心技术水平和技术创新产出能力的影响始终不明显;R&D对中国汽车制造业技术创新能力的提升具有显著的正向影响,影响强于FDI且存在滞后效应。中国汽车制造业应积极引导外资流向产业研发机构,提高外资用于创新投入的比例;加大R&D投入,着重依靠自主创新,从根本上提升技术创新能力。  相似文献

现有研究在探讨企业R&D投入与创新绩效之间的关系时,忽略了技术获取模式在其中的调节作用。本文以企业技术获取模式为调节变量,提出了R&D投入、技术来源、国外技术引进方式和企业创新绩效的理论模型,并结合浙江高技术企业的问卷调查结果,采用分组回归方法进行实证分析。研究发现:企业R&D投入与创新绩效显著正相关;以自主研发作为企业主要技术来源,以及以购买技术资料或专利作为引进国外技术的主要方式,对企业R&D投入与创新绩效的关系起正向调节作用;以合作研发为主要技术来源,以及以购买设备、购买样品、聘请国外技术人员等为引进国外技术主要方式,对企业R&D投入与创新绩效的关系起反向调节作用。  相似文献

The various strands of extant empirical research are inconclusive about the complementarity or substitutability between different innovation mechanisms, such as internal and external R&D. Using a panel sample of 83 incumbent pharmaceutical firms covering the period 1986-2000, our empirical analysis suggests that, instead of a clear-cut answer to the question of whether internal and external R&D are complementary or substitutive innovation activities, there appears to be a contingent relationship between internal and external R&D strategies in shaping a firm's innovative output. The results from our study indicate that the level of in-house R&D investments, which is characterized by decreasing marginal returns, is a contingency variable that critically influences the association between internal and external R&D strategies. In particular, internal R&D and external R&D, through either R&D alliances or R&D acquisitions, are complementary innovation activities at higher levels of in-house R&D investments, whereas at lower levels of in-house R&D efforts, internal and external R&D turn out to be substitutive strategic options.  相似文献

This paper analyses the effects of the deregulation policy introduced in India in the mid-1980s on the relationship between technology imports and in-house R&D efforts. Using appropriate statistical techniques, it examines the interactions between policy regime, economic environment and the determinants of inter-industry variation in technology imports in Indian manufacturing. In doing so, it introduces R&D efforts as one of the main determinants. Literature suggests that there is simultaneity in the relationship between technology imports and R&D efforts. To tackle this problem, lagged R&D expenditure intensity is adopted as a proxy for in-house R&D efforts. The empirical results reveal that technology imports were only weakly related with the past in-house R&D efforts in the protective regime. Deregulation promoted complementarity between technology imports and R&D efforts significantly. The results also suggest that after deregulation, the impact of product differentiation, demand conditions and technology-related factors increased significantly in determining the inter-industry patterns of technology imports. Thus, unlike in a regulated regime where technology imports are viewed important for filling gaps in domestic technological capabilities, in a deregulated regime technology upgradation seems to be the major role of technology imports.  相似文献

The standard empirical framework for analysing the R&D-patents relationship is widened both by examining the different role of in-house and contracted R&D in the innovative performance of firms, and by considering patents and utility models counts as measures of innovation output. Patents and utility models are considered to approximate for significant and incremental innovations, respectively. Applying count data econometrics to a panel data set of Spanish manufacturing firms surveyed in the period 1990-1996, a transcendental production function is estimated, which allows for non-constant elasticities of the R&D inputs. The results indicate that significant innovations are mainly gestated in-house, whereas contracted R&D seems more orientated towards innovations of incremental nature.  相似文献

This study empirically investigates the impact of foreign country factors like market size, technological strength of industries, and science and engineering (S&E) capability on the conduct of U.S. overseas R&D during the 1991-2002 period. We find that overseas markets primarily predict the entry of U.S. R&D, while the S&E capability of nations is strongly correlated with the post-entry intensity of U.S. foreign subsidiaries’ innovative activity. We also find important inter-industry differences: U.S. electrical, electronics, computer, and telecommunication industries are strongly drawn towards overseas S&E capacity; industries including Machinery, Automobiles, and Transport equipment are primarily attracted by the technological strength of foreign industry; U.S. R&D in Chemicals mostly follows overseas markets. We discuss the implications of our results to the global organization of innovative activity and innovation policy.  相似文献

The scope of this paper is to report new empirical evidence on the determinants of R&D co-operation. Indeed, the literature on the capabilities of firms emphasises the role of knowledge in the performance and evolution of firms who use knowledge developed in others to build their own knowledge capital. R&D co-operation between firms is one of the many strategies by which this knowledge may be transmitted. Several theoretical models have stressed that R&D co-operation is more likely when the level of spillovers is high. While this supposition is used in many theoretical models, it has rarely been tested before. Our results do not lend strong support to this intuition. Indeed, our spillover variables (national pure spillovers, national rent spillovers and imports of machine tools), which were supposed to match the theoretical notion of spillovers used in these theoretical models have a positive but not a significant role when explaining R&D co-operation. The R&D co-operation increases with size and with R&D intensity, but not with market share. It also increases with the budget spent on paying license fees and on acquiring patents and labour from foreign firms. In this study, we also analyse the determinants of innovation. In more precise terms, we compare the effects of R&D co-operation to those played by traditional internal factors and those exerted by external, pure and rent spillovers on the innovation capacity of the firms. Our results show that the commercial success of innovations of French firms depends mainly on size, market share, R&D intensity and human capital. Inward FDI from industrialised countries exerts a positive and significant effect. The finding highlights the important role of the absorptive capacity of firms. Spillover measurements, such as the acquisition of machine tools, foreign patents, licenses, and technological opportunities have a positive impact on innovation.  相似文献

This paper examines the impact of investments in modernization and innovation on productivity in a sample of firms in the global pulp and paper industry. This industry has traditionally accounted for significant amounts of employment and capital investment in North America and Europe. In contrast to much of the existing literature which focuses on the impact of R&D and patents on firms’ performance and productivity, we examine data on actual investment transactions in four main areas: (i) mechanical, (ii) chemicals, (iii) monitoring devices and (iv) information technology. We find that firms that implemented a greater number of investment transactions in modernization achieved higher productivity, and these estimated quantitative effects are greater than the impact of standard innovation variables such as patents and R&D. Investment transactions in the information technology and digital monitoring devices imparted a particularly noticeable boost to productivity. These results are obtained after controlling for other firm-specific variables such as capital intensity or mergers and acquisitions. Thus, firms’ decisions to undertake investments in modernization and incremental innovations appear to be critical for achieving gains in productivity, compounding to form meaningful differences in performance, productivity and competitive position across firms in the longer run. For some of the traditional industries like pulp and paper, R&D and patents seem to be particularly poor indicators of innovation and, more generally, how firms go about achieving gains in productivity.  相似文献

本文在创新驱动型增长理论的基础上,引入人力资本变量,并将研究背景放到开放型经济系统中,考察R&D、国际技术外溢和人力资本对我国技术进步的作用。协整检验表明国内研发投入和人力资本与我国全要素生产率之间存在长期均衡关系,而国外研发则由于我国技术吸收能力的问题未能对全要素生产率产生良好的效果。进一步的误差修正模型表明人力资本对我国全要素生产率有一定的滞后效应。  相似文献
