International R&;D Spillovers Revisited

Using newly constructed panel data from seventeen OECD countries during 1971–2000, this paper examines the effect of international R&D spillovers via intermediate goods imports on a country’s productivity. Estimation models are built on the model of Coe and Helpman (1995). They are tested and estimated using improved econometric techniques for panel cointegration test and estimation. Estimation results confirm the robust positive effect of international R&D spillovers through the channel of intermediate goods imports. This contradicts recent skepticism about the results of Coe and Helpman (1995) that has been raised with the development of panel data econometrics.     

Innovation, international R&D spillovers and the sectoral heterogeneity of knowledge flows

We analyze the relative effects of national and international, intrasectoral and intersectoral R&D spillovers on innovative activity in six large, industrialized countries over the period 1980–2000. We use patent applications at the European Patent Office to measure innovation and their citations to trace knowledge flows within and across 135 narrowly defined technological fields. Using panel cointegration we show that intersectoral spillovers have a key impact on innovation activities and that domestic R&D has a stronger effect than international R&D. However, within technological fields, estimated international R&D spillovers are 2.4 times the national R&D effects. We find significant differences across chemicals, electronics and machinery industries.     

Technological factors and total factor productivity in China: Evidence based on a panel threshold model

This study investigates the effects of technological factors, including indigenous research and development (R&D) investments, technology spillovers coming from foreign direct investments, export, and import, on China's total factor productivity (TFP). Using provincial panel data of China, covering 30 provinces over the period 2000–2014, our results confirm that indigenous R&D investments play a leading role in promoting TFP. Linear analysis suggests that, except for export, the technology spillovers through openness are beneficial for TFP growth. However, a further discussion based on a panel threshold model suggests that the different behaviours of these technology spillovers are dependent on the technological absorptive capacity affecting factors, such as human capital and indigenous R&D investments. The human capital will strengthen the spillover effects of each technology spillover. However, R&D intensity initially tends to hamper their spillover effects. Once the R&D intensity exceeds a certain level, the negative spillover effect of export on TFP tends to be alleviated, and the positive spillover effect of foreign direct investment and import on TFP will increase.     

Innovation,Technology Transfer and Labor Productivity Linkages: Evidence from a Panel of Manufacturing Industries

The paper explores the linkages between labour productivity, innovation and technology spillovers in a panel of manufacturing industries. The roles of R&D, human capital and international trade are considered in stimulating innovation and/or facilitating technology transfer. Using panel-based unit root tests and cointegration analysis, the results indicate the existence of a single long-run equilibrium relation between labour productivity, innovation and technology transfer. Further, R&D, trade and human capital have statistically and, especially the latter, quantitatively important effects on labour productivity both directly via innovation and indirectly as they enhance technology diffusion.

Efficiency change and productivity growth in agriculture: A comparative analysis for selected East Asian economies

This study focuses on identifying the sources of agricultural growth for eight East Asian economies – with special emphasis on factors that can better explain different components of growth. The Malmquist productivity growth index and its two components are calculated and regressed on variables including the human capital endowment, domestic R&D, international spillovers, and country-specific farming characteristics to characterize the differential patterns of growth. Our empirical evidence suggests that domestic R&D and its interaction with human capital constitute the major determinant of individual economy's progress in agricultural technology, whereas the human capital endowment is crucial for the catching up effect. Furthermore, for foreign knowledge to contribute to productivity growth either through innovation or through catching up, the host economy has to develop a sufficient learning capacity from education. Countries that do not attempt to develop the learning capability to assimilate and exploit the freely available knowledge may not benefit from international spillovers of agricultural R&D.     

Investigating the relationship between health and economic growth: Empirical evidence from a panel of 5 Asian countries

In this paper, we investigate the relationship between health and economic growth through including investment, exports, imports, and research and development (R&D), for 5 Asian countries using panel unit root, panel cointegration with structural breaks and panel long-run estimator for the period 1974–2007. We model this relationship within the production function framework, and unravel two important results. First, we find that in all four variants of the growth model, variables share a long-run relationship; that is, they are cointegrated. Second, we find that in the long-run, while health, investment, exports, EDRD (the interaction term between education and R&D), and R&D have contributed positively to economic growth, imports have had a statistically significant negative effect while education has had an insignificant effect. We draw important policy implications from these findings.     

Technology spillovers,absorptive capacity and economic growth

By establishing an endogenous growth model with knowledge-driven R&D, this paper aims to investigate the relationship between international technology spillovers, the host country's absorptive capability and endogenous economic growth. The solution to the competitive equilibrium problem shows that long-run growth arises from improvements in absorptive capability and higher human capital stocks, while the relationships between openness, the technology gap and the steady-state growth rate are uncertain. Econometric estimates of China's economic growth are obtained using province level data covering the period 1996–2002. The estimates indicate that technology spillovers depend on the host country's human capital investment and degree of openness, and that FDI is a more significant spillover channel than imports.     

How do Chinese industries benefit from FDI spillovers?

Recently, Foreign Invested Enterprises (FIEs) in China have increased their investment in not only production activity but also R&D activity. This paper examines the impact of spillovers from such activities by FIEs on two types of innovations by Chinese domestic firms: Total Factor Productivity (TFP) and invention patent application, using comprehensive industry and province-level data. We evaluate such spillovers according to FIEs' ownership structure, the origin of foreign funds and whether they are from the same industry or from other industries. We find an interesting asymmetry between spillovers to TFP and invention patent applications; while we do not find significant intra-industry spillovers from FIEs but find robust inter-industries spillover related to TFP, we find substantial intra-industry spillovers promoting invention patent applications but no evidence of inter-industries spillovers. Furthermore, whereas spillovers from FIEs to Chinese firms' TFP stem from their production activities, the source of spillovers related to invention patent applications is mostly through their R&D activity. Our findings indicate a need for multidimensional evaluation of the role of FDI in developing countries.     

Panel Cointegration Estimation of International Knowledge Spillovers

Abstract

This paper estimates the effect of international knowledge spillovers through import on a country's productivity, using panel data from 13 Organizations for Economic Cooperation and Development (OECD) countries during 1981–1999 and two alternative estimation methods for the panel cointegration model. The results confirm the robust effect of international knowledge spillovers through the flows of intermediate goods import. The magnitude of the effect is much greater in the non-G7 countries than in the G7 countries according to the fully modified ordinary least squares (OLS) estimation. By contrast, domestic knowledge capital stocks help enhance a country's productivity only in the G7 countries.     

R&D Tournaments with Spillovers

This paper studies the influence of uncertainty and spillovers on a contestant's R&D spending. The relationship between market structure and R&D spending is shown to be sensitive to the form of uncertainty that characterizes the R&D process. When reward to the winner is endogenously determined by R&D spending, a contestant's R&D spending may increase with the degree of spillovers.     

Knowledge spillovers from foreign direct investment in R&D: Evidence from Japanese firm-level data

This study uses firm-level panel data from the Japanese manufacturing industries and examines whether foreign direct investment generates intra-industry knowledge spillovers to domestic firms. The analysis found positive effects of R&D stocks of foreign firms on the productivity of domestic firms, while effects of capital stocks of foreign firms were absent, suggesting that knowledge of foreign firms spills over through their R&D activities, but not through their production activities. In addition, we found that the extent of spillovers from R&D stock of foreign firms is substantially larger than spillovers from R&D stock of domestic firms.     

Impact of Outward Foreign Direct Investment on Domestic R&D Activity: Evidence from Taiwan's Multinational Enterprises in Low‐wage Countries

This paper theoretically and empirically investigates the home‐country effects of a firm's outward foreign direct investment (OFDI) activity, specifically OFDI motivated by lower labor costs in the host country. A two‐country imperfect competition model is developed, and the interaction between a firm's R&D spending and its OFDI is examined. It is found that the relationship between a firm's OFDI and its domestic R&D is indeterminate because there is a complementary effect as well as a substitution effect induced by OFDI activity. Panel data on Taiwanese manufacturing firms from 1992–2005 are applied to test the validity of the theoretical results. The propensity score matching method is used to construct a comparison group without selection bias. Our empirical evidence reveals that a Taiwanese firm's OFDI is positively related to its domestic R&D spending, particularly in R&D‐intensive industries.     

The role of regional knowledge spillovers on China's innovation

The new economic geography has increased attention on the spatial dimension of knowledge spillovers and innovation. In this paper, we test the hypothesis that regional knowledge spillovers positively influence China's innovation growth from 2001 to 2008. As knowledge is subjected to spatial decay, innovation of a region is enhanced when location in neighboring regions encourages the formation of regional knowledge and information flows. Applying a spatial autoregressive model to China's provinces, the paper finds that regional knowledge spillovers have a favorable effect on design, invention and utility patents. This indicates that proximate location to innovative neighbors can help to raise the innovation capability of a province. In addition, evidence also shows that R&D expenditure and skilled personnel of research institutes and universities positively affect invention and utility patents. This suggests a favorable role for the government in enhancing indigenous innovation capability.     

Estimating international technology spillovers using technology flow matrices

Estimating International Technology Spillovers Using Technology Flow Matrices. — This paper investigates the impact of international R &; D spillovers on sectoral growth patterns in OECD countries. It applies panel regression techniques to a time-series cross-section panel. It arrives at the conclusion that knowledge spillovers are an important contributor to economic growth. The estimation results are applied in the form of a ‘simulation’ of TFP growth per country, splitting (R &; D-related) TFP into a component due to domestic R &; D and one due to foreign R &; D. The results also show that the United States and Germany are the most influential countries in terms of contributions to other countries’ TFP growth.     

研发效率、技术溢出与政府的创新补贴

 在一个三阶段博弈模型的基础上,本文研究了存在技术溢出情况下政府的创新激励政策与企业的研发策略。结果表明,无论是实行竞争型创新补贴政策还是合作型创新补贴政策,政府都应该优先补贴那些低成本、高效率的创新行为。贸易自由化提高了国家的创新补贴水平,但是技术溢出本身对创新补贴的影响却具有不确定性。文章的结果同时显示,贸易便利化的实施与高技术溢出提高了消费者剩余与国民福利水平。贸易壁垒虽然强化了企业对本国市场的垄断,但是,在考虑了政府的创新补贴政策后,具有创新激励的企业实际上更倾向于自由贸易结果,因此,相对于严格的专利保护制度,创新补贴政策可能更容易促进国民福利水平的提高。     

In search of FDI-transmitted R&D spillovers: A study based on Swedish data

In Search of FDI-Transmitted R& D Spillovers: A Study Based on Swedish Data. — This paper analyzes empirically whether inward and outward foreign direct investment (FDI) work as channels for international R&D spillovers. The authors utilize firm-level and industry-level data for Swedish manufacturing. Hardly any evidence of FDI-related R&D spillovers is found. But while the results do not provide support for the hypothesis that the activity level of MNEs’ affiliates matters for the extent of FDI-transmitted international spillovers, they suggest that utilizing foreign affiliates’ employment as a weighting scheme may be too crude a measure. The authors’ analysis shows indeed that the type of activity — R&D or assembly — carried out in the affiliates matters significantly for technology sourcing.     

Openness,human capital and total factor productivity: evidence from China

This paper examines the drivers behind China's economic growth. In particular, it focuses on the channels of knowledge spillovers: human capital and openness to trade and foreign direct investment. The specific features of the study include using the most recent comprehensive panel data consisting of 29 provinces during the period 1994–2006 and performing unit root and cointegration tests in the panel data framework. The paper finds that human capital, trade and FDI are the significant determinants of total factor productivity, but their importance varies with technological levels of provinces. These findings have important policy implications.     

The Impact of Research and Development on Economic Growth and Productivity in the U.S. States

Research and development (R&D) has a large effect on both state output and total factor productivity in the long run. Our estimates for the private sector of the U.S. states from 1963 to 2007 show that the R&D elasticity averages 0.056–0.143. The implied returns to state Gross Domestic Product (GDP) from R&D spending are 82–211%. There are also positive R&D spillovers, with 70–80% of the total returns accruing to other states. We also find that states with more human capital have higher own‐ and other‐R&D elasticities, and those in lowest tier of economic development have the least own‐state R&D elasticity but the highest other‐R&D elasticity. In addition, we find that the positive effect of R&D spillovers across states is larger when we consider R&D spillovers across states based on economic similarity of R&D across sectors.     

R&D and the Export Decision of New Firms

Recent literature on the firm‐level decision to export has focused on identifying factors that influence the export decision by firms regardless of the number of years they have been in operation. This article, alternatively, examines the factors that influence new firms to export within the first four years of operation. The results support two key findings that have commonly emerged from entrepreneurial case studies: (1) There is a positive link between research and development (R&D) and early internationalization, and (2) international ties of managers, as is evidenced by the effect of foreign‐born owners, positively impact the firm's decision to export. The former result is the emphasis of this article. In addition, we find that innovation spillovers from neighboring firms impact the export decision of new firms that engage in R&D.     

Technology transfer on a two-way street: R&D spillovers through intermediate input usage and supply

Intermediate input usage is known to channel R&D spillovers across countries and industries. This paper highlights that technology also diffuses across countries and industries through intermediate input supply. Technology transfer to intermediates suppliers ensues from R&D that induces a demand for technologically advanced intermediates. I analyze R&D spillovers through intermediate input usage and supply for 18 manufacturing industries in 20 OECD countries over 1987–2009. Results support both use- and supply-driven R&D spillovers. Comparing their effects reveals interesting variations. Among domestic industries, intermediate input supply is the dominant channel. For international relations, both use- and supply-driven R&D spillovers are found.
