Influence of export on innovation activities of domestic enterprises

Using the panel data from 2001 to 2003 across manufacturing industries in China, this paper analyzes the intra-industry and inter-industry spillovers from export on the productivity and innovation activities of domestic enterprises in China. Among the industries we investigate and in the sample session, there are evidences of positive backward linkage spillovers to the process innovation of domestic enterprises, and negative backward linkage spillovers to the product innovation activities. Based on the findings, we make some policy suggestions.      

Interrelationship among foreign presence,domestic sales and export intensity in Chinese manufacturing industries

Using panel data on six Chinese manufacturing industries over the period 2005–2007, this article explores the interrelationship among foreign presence, domestic sales and export intensity of local firms. We find that the domestic sales and exports are complementary for local firms in China’s pharmaceutical industry, whereas in the case of the textile, transportation equipment, beverage, communication equipment and general equipment manufacturing industries, domestic sales and exports are substitutes. An increase in the average domestic sales increases foreign presence in all industries. The same applies to an increase in the average export intensity. An increase in the level of competition in China’s textile industry increases the export intensity as well as domestic sales of local textile firms. However, an increase in the level of competition in the pharmaceutical industry leads to a very large decrease in export intensity of local pharmaceutical firms. In the case of China’s transportation equipment manufacturing industry, an increase in the level of competition decreases domestic sales of local firms. Furthermore, an increase in the firm size increases domestic sales of Chinese firms in all six manufacturing industries.     

Estimation of foreign MNEs spillovers in Spain

Using Spanish firm-level data, we estimate productivity effects of spillovers from foreign multinationals to domestic firms in both manufacturing and service sectors. We find evidence of a positive productivity effect from multinationals on domestic firms operating in the same industry. Analyzing inter-industry linkages, we find evidence consistent with positive productivity spillovers from forward linkages (i.e. from suppliers to buyers) and negative productivity spillovers from backward linkages (i.e. from buyers to suppliers). Our main results hold when analyzing differences between multinational and domestic firms, and for periods of economic growth and recession, although some differences arise. Interestingly, we find evidence supporting a positive role of spillovers during the last recession period.     

R&D spillovers and productivity: Evidence from U.S. manufacturing microdata

This paper deals with the estimation of the impact of technology spillovers on productivity at the firm level. Panel data for American manufacturing firms on sales, physical capital inputs, employment and R&D investments are linked to R&D data by industry. The latter data are used to construct four different sets of `indirect' R&D stocks, representing technology obtained through spillovers. The differences between two distinct kinds of spillovers are stressed. Cointegration analysis is introduced into production function estimation. Spillovers are found to have significant positive effects on productivity, although their magnitudes differ between high-tech, medium-tech and low-tech firms.

Knowledge spillovers in biotechnology: sources and incentives

This paper sheds light on the questions, Why does knowledge spill over? and How does knowledge spill over? The answer to these questions we suggest lies in the incentives confronting scientists to appropriate the expected value of their knowledge considered in the context of their path-dependent career trajectories. In particular, we focus on the ability of scientists to appropriate the value of knowledge embedded in their human capital along with the incentive structure influencing if and how scientists choose to commercialize their knowledge. We conclude that the spillover of knowledge from the source creating it, such as a university, research institute, or industrial corporation, to a new-firm startup facilitates the appropriation of knowledge for the individual scientist(s) but not necessarily for the organization creating that new knowledge in the first place.     

Multinational enterprises and technological spillovers: An evolutionary model

This paper analyses the determinants of the impact of foreign multinational enterprises on the technological development of domestic firms. It argues that the consequences of the foreign presence change according to market and technological conditions. An evolutionary model of technological competition between foreign and domestic firms is developed which is able to generate both vicious and virtuous circles of development in locations affected by foreign MNE activities. Theoretical analysis is tested against the empirical evidence for the UK economy (1983–1989).     

Agglomeration externalities: Marshall versus Jacobs

The literature remains inconclusive as to whether Marshallian specialization or Jacobian diversification externalities favor regional innovativeness. The specialization thesis asserts that regions with production structures specialized towards a particular industry tend to be more innovative in that particular industry, as it allows for knowledge to spill over between similar firms. The diversification thesis argues that knowledge spills over between different industries, causing diversified production structures to be more innovative. A closely related debate evolves around local competitiveness hypotheses. Using an original database of innovation counts, both these issues are addressed for the Dutch context. The results show that the Marshallian specialization thesis holds, though more pronounced for R&D intensive and small firms. Fierce local competition within an industry negatively affects innovativeness in that particular industry.JEL Classification: O18, O31, R10Gerben van der Panne: The author wishes to thank Fia Wunderink, Wilfred Dolfsma and Alfred Kleinknecht for helpful comments on an earlier version of this paper.     

International knowledge spillovers and wage inequality in developing countries

In this paper, international knowledge spillovers are incorporated in a horizontal innovation model, designed to explain the observed uncertain effects that openness of trade can have on wage inequality in small developing countries. Openness of trade can produce two different effects: an increase in the relative price of less-skilled labor-intensive products and a wider skill discrepancy due to knowledge spillovers from the more to less developed country. The former triggers a fall in the wage premium, while the latter widens the wage premium gap in a developing country. These two opposing forces explain the observed uncertain effects of openness to trade on wage inequality in developing countries.     

Banking sector resilience to financial spillovers

By using a large sample of bank-level data, we analyse whether the spillover effects of US financial shocks differ with the fundamental characteristics of the banking sectors in the affected countries. We find that a banking sector characterized by a higher degree of competition and larger margin of safety is less affected by financial spillovers. The results are robust to the inclusion of bank-level control variables that capture individual banks’ lending capacity.     

More on subsidizing cooperative and noncooperative R&D in duopoly with spillovers

In an earlier article in this journal I compared two R&D-stimulating policies: allowing for R&D cooperatives and providing direct R&D subsidies (see Hinloopen, 1997:Journal of Economics 66: 151–175). I also considered the implementation of both policies simultaneously. Since then Amir (1998: Discussion Paper 1/1998, Odense University) has shown that the model I used as a starting point (i.e., that of d'Aspremont and Jacquemin, 1988:American Economic Review 78: 1133–1137) is not well-defined with respect to a crucial parameter (the technological spillover) and subsequently proposes an augmentation of the model. Replicating then my original analysis with this augmented model reveals that all results stated before remain valid. In addition I correct a minor error in Hinloopen (1997) related to the comparison of optimal R&D subsidies.     

What drives innovativeness in industrial clusters? Transcending the debate

The paper throws new light on the debate about the role playedby local knowledge spillovers (LKS) as a driver of regionalinnovative activity. It transcends the regional level of analysisthat has been commonly adopted in the literature so far, usinginsights from the evolutionary theory of the firm. This makesit possible to derive a typology of mechanisms through whichregional agglomeration may stimulate learning and innovationat the firm level. When this typology is brought to bear onthe extant approaches in the debate, the contrasting viewpointscan be reconciled to some extent. The main conclusion is thatlittle theoretical ground for the LKS debate remains.     

The importance of clusters for spillovers from foreign direct investment and technology sourcing

This paper examines the link between cluster development andinward foreign direct investment. The conventional policy approachhas been to assume that inward foreign direct investment (FDI)can stimulate significant clustering activity, thus generatingsignificant spillovers. This paper, however, questions thisand shows that, while clusters can generate significant productivityspillovers from FDI, this only occurs in pre-existing clusters.Further, the paper demonstrates that foreign-owned firms thatenter clusters also appropriate spillovers when domestic firmsundertake investment, raising the possibility that clustersare important locations for so called technology, or knowledgesourcing activities by MNEs.     

Technology transfers,foreign investment and productivity spillovers

This paper explores the relationship between foreign direct investment (FDI) and the productivity of host country domestic firms. We rely on a specially designed survey of over 4000 manufacturing firms in Vietnam, and separate out productivity gains along the supply chain (obtained through direct transfers of knowledge/technology between linked firms) from productivity effects through indirect FDI spillovers. In addition to identifying indirect vertical productivity spillovers from FDI, our results show that there are productivity gains associated with direct linkages between foreign-owned and domestic firms along the supply chain not captured by commonly used measures of spillovers. This includes evidence of productivity gains through forward linkages for domestic firms which receive inputs from foreign-owned firms.     

Threshold effect of international technology spillovers on China's regional economic growth

ABSTRACT

This study uses China's provincial panel data for 2003–2016 to estimate the turning point of technology spillovers promoting economic growth in the coastal and inland areas. The results show that the turning point in coastal areas is significantly higher than that in inland areas. However, improved absorptive capacity as a result of regional disparity increases the threshold of technology spillovers from promotion to suppression in inland areas but decreases it in coastal areas. Then, this study further tests the threshold characteristics of absorptive capacity factors influencing international technology spillovers using a double-threshold regression model and estimates the threshold values of both forward and reverse spillovers from the viewpoint of knowledge context, economic development, opening degree and human resources infrastructure. In conclusion, the effect of absorptive capacity factors on international spillovers is nonlinear, that is, when absorptive capacity factors are between the two threshold values, technology spillovers are maximised.     

Volatility spillovers and macroeconomic announcements: evidence from crude oil markets

The paper applies an event study methodologyaims to investigate the macroeconomic announcements effects on Standard&Poor’s500 and oil prices. Our results provide evidence for a significant impact of the US macroeconomic news on oil prices. This impact is split into two components, namely the direct effect (common response) and indirect effect (volatility transmission). Altogether our results show that the volatility transmission is bidirectional. Not only a significant volatility transmission from the oil market to the US stock market is revealed, but also a high volatility transmission is recorded from the oil market to the stock market especially after the release of consumption indicators.     

North-South knowledge spillovers and competition: convergence versus divergence

Technology spillovers from high-productivity countries in the North allow low-productivity countries in the South to improve productivity in high-tech sectors relatively easy. However, the South's share in world goods markets for high-tech products is relatively low, which reduces opportunities for learning by doing. Our simple Ricardian endogenous growth model shows how the balance between toughness of competition in trade and the strength of North-South spillovers determines whether productivity levels diverge, partially converge or fully converge in the long run. If convergence prevails, the North is confronted with declining employment in high-tech sectors. Temporary (trade) policy measures can turn a diverging economy into a converging one.     

Do domestic firms learn to export from multinationals?

Attracting inward investment is a major preoccupation of policymakers worldwide, and a wide range of instruments, including direct subventions, are deployed to attract multinational enterprises (MNEs). Intervention is predicated on the assumption that there are direct productivity spillovers associated with the presence of MNEs and the policy of attracting them is targeted at capturing these externalities. Yet robust evidence on direct spillovers is hard to find. An underexplored indirect channel for productivity spillovers is via exports. Exporting firms are more productive than nonexporting firms. Thus, if the presence of MNEs results in more indigenous firms exporting, an indirect productivity spillover will result. In this paper, we identify possible transmission mechanisms for export spillovers and test for their existence on a large panel of firms in the UK. Our results confirm positive spillover effects from MNEs on the decision to export of UK-owned firms as well as on their export propensity.     

进口技术外溢、出口相似度与我国出口商品结构优化

笔者研究发现,对发达国家总体而言,进口技术外溢通过进口渗透率来促进出口商品结构优化;而对于G7国家,从其进口产生的技术外溢本身就能促进我国出口商品结构优化,进口渗透率并不是必要的因素.国内研发投入的提高能促进我国出口商品结构的优化.     

Endogenous spillovers and incentives to innovate

Summary. We present a new approach to endogenizing technological spillovers. Firms choose levels of a cost-reducing innovation from a continuum before they engage in competition for each other's R&D-employees. Successful bids for the competitor's employee then result in higher levels of cost reduction. Finally, firms enter product market competition. We apply the approach to the long-standing debate on the effects of the mode of competition on innovation incentives. We show that incentives to acquire spillovers are stronger and incentives to prevent spillovers are weaker under quantity competition than under price competition. As a result, for a wide range of parameters, price competition gives stronger innovation incentives than quantity competition. Received: February 1, 1999; revised version: November 14, 2001
