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。     

Do R&D tax incentives work? Firm-level evidence from China

Tax incentives have been used worldwide to encourage firm R&D, but there is little evidence on their effectiveness as a policy tool in developing countries. We use a panel dataset of Chinese listed companies covering 2007 to 2013 to assess the effects of tax incentives on firm R&D expenditures and analyze how institutional conditions shape these effects. Our results show that tax incentives motivate R&D expenditures for our sample firms. A 10% reduction in R&D user costs leads firms to increase R&D expenditures by 3.97% in the short run. We also find considerable effect heterogeneity: Tax incentives significantly stimulate R&D in private firms but have little influence on state-owned enterprises' R&D expenditures. Moreover, the effects of tax incentives are more pronounced for private firms without political connections. Hence, reducing political intervention complements tax incentives' capacity to foster firm R&D in developing countries.     

Self-selection and performance of R&D input of heterogeneous firms: Evidence from China's manufacturing industries

Applying the theories of heterogeneous firms and the propensity score matching difference-in-differences (PSM-DID) method to a rich dataset of Chinese manufacturing firms, this paper examines the self-selection of firm-level R&D input and estimates the net effect of R&D on productivity. The analysis shows that (1) for Chinese manufacturing firms as a whole, R&D input is influenced by firm productivity: more productive firms are more likely to invest in R&D; (2) controlling for the self-selection effect, the net output elasticities of R&D input in one year and two years after R&D input are 3.92% and 5.25%, respectively; (3) although state-owned enterprises (SOEs) are more likely than all other ownership groups to invest in R&D, the R&D input is not productive; (4) although enterprises owned by investors outside of Mainland China are the least likely to invest in R&D, the output elasticity of R&D is more significant and larger in this group than in SOEs and privately owned Chinese firms; and (5) surprisingly, the net effect of R&D is not significant in high-tech industries. Policy implications are derived from the findings.     

R&D intensity and domestic and cross-border M&A of Japanese firms before domestic M&A deregulation

In this paper, we examine the determinants of mergers and acquisitions (M&A) in Japan prior to the deregulation of domestic M&A transactions. We reveal that firm growth strategies and institutional differences in domestic and cross-border transactions are key determinants of the differences in M&A behavior. Our estimates show that domestic M&A activities are negatively related to research and development (R&D), suggesting that low technology-intensive firms have a tendency to engage in domestic M&A. For cross-border M&A, firm R&D activities have a significant positive effect, implying that a firm's own technology is important for absorbing foreign technology or competing in the host country.     

Process and product R&D by a multiproduct monopolist: a reply to Lin

With reference to Lambertini (2003), Lin correctly points outthat, if R&D efforts for process innovation are endogenous,then process and product R&D are strategic complements.Then, he also proves that the opposite holds when spilloversare nil. Objecting to Lin's second claim, I show that monopolyprofits are everywhere increasing in the extent of informationsharing within the firm. Consequently, the full internalisationof spillovers restores the complementarity between process R&Dand product proliferation.     

Is R&D cash flow sensitive? Evidence from Chinese industrial firms

We hypothesize that research and development (R&D) is sensitive to cash flow fluctuations due to asymmetric information and agency problems in the credit market. We adopt a variant of the Q model for R&D investment using the value of the firm, physical capital and employment to capture firm fundamentals as proxies for investment opportunities. We add cash flow to this specification, and estimate the augmented model separately for R&D participation and spending decisions using data on Chinese industrial firms for the period 2001–2006. We find that R&D participation and spending are sensitive to cash flow fluctuations, conditional on firm fundamentals. We also find that the cash flow sensitivity of R&D varies across firms depending on ownership.     

Advertising, in-house R&D, and growth

This paper develops a quality-ladder model of endogenous growthto study the interplay between in-house R&D and combativeadvertising expenditure, and its implications for economic growth,firm size, and welfare. The analysis shows that, somewhat surprisingly,higher incentives to engage in advertising, although combative,unambiguously foster innovation activity of firms. This, possibly,leads to faster growth and even higher welfare. These resultsrest on two features of the model which are well-supported byempirical evidence. First, if firms incur higher sunk costsfor marketing, concentration and firm size rise. Second, firmsize and R&D expenditure are positively related as largerfirms are able to spread R&D costs over higher sales. Theanalysis also suggests that R&D subsidies are conduciveto R&D and growth without inducing firms to raise advertisingoutlays.     

The effects of product liability costs on R&D with asymmetric information

This paper examines the effects of product liability costs on R&D with asymmetric information. When the product is defective, both the consumer and producer share the resulting losses. This paper explores the impacts of liability costs on the firm’s R&D decisions in three information structures: full information; hidden information; and hidden information and hidden action. It is found that the effects differ across information structures. This paper also compares the equilibrium amounts of R&D and social welfare levels across three cases. Equilibrium R&D is smaller than the socially optimal level for each information structure.     

'Successes' and 'Failures' in the Markets for Technology

Market-mediated contracts for technology trade are bound byseveral transaction costs. This paper argues that as these transactioncosts become less severe, markets for technology can help improvethree market failures: (i) R&D duplications; (ii) externalitiesin potentially public R&D outcomes; and (iii) deviationsfrom marginal cost pricing in the downstream product markets.In addition, with larger markets of potential users, the technologysuppliers will have incentives to produce more ‘general’technologies which span a wider number of firms or industries.Markets for technology also produce new failures. In particular,they induce deviation from marginal cost pricing in the saleof the technology, and they generate externalities associatedwith complementary R&D and other investments made by theindependent buyers and suppliers that operate in them. The paperconcludes by discussing policy implications.     

R&;D,trade, and productivity growth in korean manufacturing

This paper investigates the effects of both R&D spillovers and trade patterns on productivity in Korean manufacturing, using industry-level data. The results show that domestic and foreign R&D capital stocks played an important R&D in improving the total factor productivity of Korean manufacturing. Moreover, productivity is higher in export industries and the more open industries, and the effects of foreign R&D capital are stronger in the industries with large import shares or large intra-industry trade shares.

Inequality in healthcare R&D outcomes: a model of process disruption

ABSTRACT

The developing world has substantively different healthcare research and development (R&D) needs than the developed world. In this paper it is argued that healthcare inequality is primarily an outcome of the incentives of an innovation system that privileges wealthy markets. Given the difficulties inherent in challenging these incentive structures, it might be the R&D process itself (rather than its incentive structures) that, if disrupted, may ultimately improve access to R&D outcomes for poor populations. The objective of this paper is to spur novel thinking about the problem of healthcare inequality by developing a provocative conceptual model of healthcare R&D process disruption, based on the application of novel technologies to the research process itself, to radically lower the costs of R&D. The model developed here suggests that healthcare inequality might ultimately be mitigated by substantial reductions in time and cost in the biomedical R&D process made possible by novel technologies.     

Is downsizing a good strategy during the downturn? Evidence from Taiwanese manufacturing firms

In response to a crisis, while retrenchments are considered to be an important part of a firm’s long-term recovery, research has indicated that downsizing strategies, reducing employment and shrinking the R&D budget, may lead to an erosion of a firm’s valuable core competence. Drawing from the literature of organizational turnaround strategies, this study advances the downsizing research by explaining how downsizing strategies affect a firm’s long-term performance. Using a uniquely compiled dataset of 2559 Taiwanese manufacturing firms, our research shows that increasing labor employment during a financial crisis can significantly improve a firm’s long-term total factor productivity and sales. In other words, employment downsizing may not be the best solution when encountering an economic downturn.     

Market competition,differences in technology,and productivity improvement: An empirical analysis based on Japanese manufacturing firm data

In this paper we examine empirically the effect of market competition on firm productivity improvements using data drawn from the Japanese manufacturing sector. We find that a non-linear relationship between competition and productivity growth induced by R&D activity as suggested by Aghion et al. (2005) holds for Japanese manufacturing firms. We also show that greater market competition widens technology differences across firms, and firms facing more intense competition are more productive than other firms. Our empirical results imply that productivity improvement through R&D activity depends on not only a competitive environment but also technological differences between firms.     

Strategic R&D Location in European Manufacturing Industries

We empirically test a model of foreign research and development (R&D) investments that takes into account strategic interaction in R&D location decisions by multinational firms in the context of R&D cross-investments, R&D spillovers and foreign technology sourcing strategies. We find support for most of the predictions of the model in an empirical analysis of the location of patented innovations by the largest European manufacturing firms in 22 ISIC industries during 1996–1997. For technology leaders in Europe, foreign R&D ratios respond positively to host country product market competition, while technology laggards avoid these locations. Foreign R&D by technology laggards increases more strongly with the efficiency of (reverse) international technology transfer while leaders are attracted more strongly to countries with better intellectual property rights (IPRs) protection. Foreign R&D of both technology leaders and technology laggards increases with the size of the local knowledge pool and the size of manufacturing operations in the host country.

R&D,financing constraints and export green-sophistication in China

This paper provides a theoretical and empirical analysis of the effects of R&D and financing constraints on the green-sophistication of Chinese firm exports. The theoretical model predicts that firms' R&D expenditure improves the level of green sophistication and financing constraints have moderating effects on firms' the export green-sophistication. The paper constructs an index of the export green-sophistication by incorporating green coefficient in traditional export sophistication. We use the data from the China industrial firm database and confirm our theoretical predictions. The financing constraints are found to have a significant moderating effects on the relationship between R&D and export green-sophistication in basic test and robustness check.     

International Trade and R&D Investment: Evidence from Chinese Manufacturing Firms

A current concern for China's long‐term growth prospect is whether China can become an innovative economy and achieve industrial upgrading to compensate for the gradually declining competitiveness resulting from low‐cost labor. The present study examines this issue by exploring how trade participation impacts on the R&D investment of manufacturing firms through various channels. Merging China's Annual Manufacturing Survey Dataset and the Chinese Customs Dataset allows us to study such a relationship at the individual firm level. The empirical results suggest that channels such as geographical diversification of export markets, share of imports from high‐income countries, average unit value of imports, number of intermediate goods and capital goods imports, and the trade regime are significant factors that influence firm‐level R&D investment. The study discusses the policy implications of the empirical findings in relation to industrial and trade policies that may be potentially beneficial for China's transition towards an innovative economy.     

R&D subsidies and business R&D: Evidence from high-tech manufacturing firms in Jiangsu

We investigate how R&D subsidies affect business R&D investments using cross-section data of high-tech manufacturing firms in Jiangsu province of China. Our estimations based on propensity score matching suggest that public subsidies positively influence business R&D investments. Further classifying firms into different groups by size, financial constraints, and ownership, we find that the stimulation effect is more significant and stronger for smaller firms, more financially constrained firms, and private-owned firms. The heterogeneity of policy effects with respect to export status, Relative Comparative Advantage index, region, and industry are also discussed.     

Process and product R&D by a multiproduct monopolist

It is shown that the claim in Lambertini that a multiproductmonopolist's incentive for process R&D declines with thenumber of products it offers is incorrect. This incentive isin fact an increasing function of the number of products inhis model. I further extend the model of Lambertini to showthat whether or not process R&D incentive and the numberof varieties are positively related depends on the degree ofscope economies in process R&D. Product innovation promotesprocess R&D if the degree of such scope economies is high(as in Lambertini), and discourages it if the degree of scopeeconomies is low.     

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.
