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

Technology acquisition channels and industry performance: An industry-level analysis of Chinese large- and medium-size manufacturing enterprises 总被引：3，自引：0，他引：3

Through an industry-level analysis of Chinese large- and medium-size manufacturing enterprises over the period of 1996-2001, this article investigates the direct and interactive contributions of four technology acquisition channels to industry performances in terms of innovation performance and productivity. These channels include in-house R&D, foreign technology transfer, domestic technology transfer, and inter-industry R&D spillover. We have found evidence of an important role of inter-industry R&D spillover in shaping and improving industry performance in China, which has been neglected by previous empirical studies concerned with Chinese industrial firms. The empirical results indicate that inter-industry R&D spillover and foreign technology transfer make significant contributions to both labour productivity and the level of total factor productivity in Chinese manufacturing industries. We have also found that in-house R&D and inter-industry R&D spillover share a complementary relationship in shaping innovation performance and total factor productivity in Chinese industry, and that in-house R&D relates to foreign technology transfer as a complement for labour productivity. Finally, on the mixed results among existing literature in the context of developing countries, this article argues that the commonly followed strategy in technology development, combined with government regulations, will play an essential role in determining the relationship between in-house R&D and foreign technology transfer. 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

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

This paper aims to contribute to the literature on the long-debated relationship between market competition and firm research and development (R&D) by investigating the effect of competitive market pressure on firms’ incentives to invest in R&D. The paper shows that a firm's R&D response to competitive market pressure depends primarily on its level of technological competence or R&D productivity: firms with high levels of technological competence tend to respond aggressively (i.e., exhibit a higher level of R&D efforts) to intensifying competitive market pressure, while firms with low levels of technological competence tend to respond submissively (i.e., exhibit a lower level of R&D efforts). The differential effect of competitive market pressure on firm R&D, conditioned primarily by the level of firms’ technological competence, is empirically supported by unique firm-level data from the World Bank. Furthermore, the role of firm-specific technological competence in conditioning the R&D-competition relationship is more evident and statistically more significant for firms facing consumers whose utility is relatively more elastic to product quality than to price. 相似文献

Regional innovation in Europe is analyzed with Fuzzy-set Qualitative Comparative Analysis, distinguishing between different economic development level categories and between innovation performance groups within each category. Different mechanisms were identified based on varying conjunctions of business and public sector R&D, spatial proximity to external R&D, networks of collaborations, tolerance and inclusion, and human capital. More developed regions present four main mechanisms that lead to regional innovation. Namely, a technologically driven mechanism, a business R&D driven technological mechanism, a mechanism driven primarily by internal R&D competencies and tolerance and inclusion, and a general path to regional innovation, supporting a public R&D driven technological mechanism. When the analysis focuses on moderate innovators, the absence of skilled human capital is added as a relevant condition owing primarily to the lack of technological and technical skills in some regions. For lagging regions, the relevant innovation definition excludes patenting as these regions focus on ‘softer’ innovation aspects than technological innovation. Innovation in lagging regions is primarily driven by public R&D supported by tolerance and inclusion or by networks of collaboration. The latter might work as a condition compensating for -often unfavorable- geography. 相似文献

This paper aims to disentangle the mechanisms through which technological similarity between acquiring and acquired firms influences innovation in horizontal acquisitions. We develop a theoretical model that links technological similarity to: (i) two key aspects of post-acquisition reorganization of acquired R&D operations – the rationalization of the R&D operations and the replacement of the R&D top manager, and (ii) two intermediate effects that are closely associated with the post-acquisition innovation performance of the combined firm – improvements in R&D productivity and disruptions in R&D personnel. We rely on PLS techniques to test our theoretical model using detailed information on 31 horizontal acquisitions in high- and medium-tech industries. Our results indicate that in horizontal acquisitions, technological similarity negatively affects post-acquisition innovation performance and that this negative effect is not mediated by the reorganization of the acquired R&D operations. However, replacing the acquired firm's R&D top manager leads to R&D productivity improvements that positively affect innovation performance. 相似文献

Stronger protection of patent rights is thought to spur innovation through securing returns to R&D investments. Those investments must be financed, however, suggesting that the responsiveness of R&D to patent reforms varies with financial development levels. We examine the joint impact of domestic and international financial-market development and patent protection on R&D intensities in 22 manufacturing industries in 20 OECD countries for the period 1990-2009. We show that stronger patent rights increase R&D intensities in patent-intensive industries, accounting for the need for external financing and the amount of tangible assets. The primary impact varies across types of financial development: patent protection raises R&D in high-patent industries where countries have more limited equity and credit markets. In contrast, in countries with more developed bond markets industry R&D is more sensitive to patent rights. Interestingly, patent rights in countries that are more exposed to foreign direct investment increase R&D intensities at all levels of financial development. 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

Under what conditions do firms benefit from the research efforts of other organizations? 总被引：1，自引：1，他引：0
Although R&D spillovers play a key role in the battle for technological leadership, it is unclear under what conditions firms build on and benefit from the discoveries of others. The study described here empirically examines this issue. The findings indicate that, depending on technological opportunities, firm size and competitive pressure, the net impact of R&D spillovers on productivity can be either positive or negative. Specifically, we find that although spillover effects are positively associated with the technological opportunities that a firm faces, this relationship is reversed when firm size is considered. Whilst external R&D affects large self-reliant firms negatively, its impact on the productivity of smaller firms (who usually introduce incremental innovations that are characterized by a strong reliance on external technologies) is positive, and even higher than that of their own R&D. We also demonstrate that the economic payoff for firms’ own R&D is lower when they face intense competition. In cases of low-appropriability, however, spillover effects are more positive, allowing firms to increase their performance using the inventions of others. 相似文献

Investments in modernization, innovation and gains in productivity: Evidence from firms in the global paper industry 总被引：1，自引：0，他引：1
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

High technology is a concept much in vogue in OECD countries, for it is a symbol of an “advanced” economy. This paper looks at why and how the concept and its indicator acquired such fame. It explains that the reason has to do with the fact that the indicator emerged in the context of debates on the competitiveness of countries and their efforts to maintain or improve their positions in world trade. The first part looks at the early statistics behind the indicator (R&D/sales), statistics developed in official analyses of industrial R&D surveys before the 1950s. The second part traces the evolution of the R&D/sales ratio in the 1960s through its use as an indicator of research or technological intensity. The third part discusses the internationalization of the indicator via the OECD. 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

We investigate country-level determinants of Official Development Assistance (ODA) in health R&D with a focus on levels and types of human suffering as well as levels and types of medical absorptive capacity. Using latest data from a range of sources and various tests on large numbers of countries in receipt of health R&D ODA, we find support for the central assertions that human burden has a direct positive impact on receipt of health R&D ODA and that medical absorptive capacity in the recipient country moderates this relationship. The relationship between human burden and health R&D ODA receipt does not hold for countries low in medical absorptive capacity. Additional analysis reveals: (1) medical absorptive capacity that involves regular patient contact has the strongest moderating effect on the burden – funding relationship, (2) receipt of health R&D ODA under low levels of medical absorptive capacity explained not by human burden but by small country bias, and (3) the importance of nurses to health R&D ODA in countries with high levels of human suffering and health R&D ODA but voids of doctors and clinical trials. 相似文献

This paper studies the impact of foreign direct investment (FDI) on total factor productivity (TFP) for a cross sectional sample of Chinese industrial sectors. The possible determinants of TFP are sought with special focus on FDI. An endogeneity test is performed in order to avoid inconsistent results. Evidence indicates that foreign presence, the level of R&D and the firm size are the most important factors enhancing TFP in Chinese industries. The findings from this study support the argument that attracting FDI is an effective way of introducing advanced technology to host countries. 相似文献
