We devise a model in which domestic firms do applied R&D, which can be subsidized by the government, and foreign firms with superior technology can enter in the domestic market. Foreign Direct Investment can act as a substitute of subsidies to improve domestic R&D, the share of domestic leading firms and consumption. Relatively closed economies may benefit from R&D subsidization while relatively open economies may not. For relatively low growth of the technological frontier, it is optimal to subsidize R&D and close the economy to foreign investment but the opposite happens for relatively high growth. Numerical simulations show the economy dynamics after policy experiments. 相似文献

Suppose a firm’s research and development (R&D) improves product reliability which in turn decreases the cost of product failure for both the firm and its customers. The primary research question of the paper is how a firm with market power optimally adjusts its R&D if it experiences a manufacturing cost shock. Our model suggests that a manufacturing cost shock prompts the firm to do less R&D in the cases where the replacement cost is low or the marginal manufacturing cost is high. Conversely, if the replacement cost is high and the marginal manufacturing cost is low, then the firm increases R&D, mitigating some of the increase in the manufacturing cost. The paper also compares the outcomes for reliability, profits, consumer surplus, and social surplus for the optimal R&D case as compared to the case of doing no R&D, paying particular attention to how exogenous changes in the marginal manufacturing cost affect this comparison. 相似文献

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. 相似文献

Whereas numerous studies have evaluated the effects of public research and development (R&D) support programs and R&D tax incentives on private R&D, little is known about local governments' fiscal incentives for R&D. In this study, we build a conceptual framework to clarify the critical role of local land supply in relation to fiscal expenditure on R&D. We treat the establishment of China's nine Land Supervision Bureaus in 2006 as a quasi-natural experiment, and run a difference-in-differences regression to identify causality. The results show that local governments allocate more fiscal expenditure to R&D in response to land-use supervision, which monitors illegal land granting behaviors, and this effect is stronger in cities where leaders have higher political career incentives and cities with greater fiscal decentralization. Moreover, we find that land-use supervision increases the probability and scale of firms' access to government subsidies for R&D; thus, enhancing regional innovation capacity. Our findings document that China's land resource is a curse for its innovation-driven growth as it impedes local governments' fiscal incentives for R&D. 相似文献

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. 相似文献

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. 相似文献

Two versions of research and development (R&D) activities in a Hotelling model with endogenous spillover effect, one with cost-reducing R&D and the other with quality-improving R&D, are analyzed in this paper. The result points out that two such kinds of R&D activities will share identical strategic properties, and that we shall be able to derive the equilibrium strategies of a quality-improving R&D model from those of a cost-reducing R&D model, and vice versa. It is found that the special market demand in a Hotelling model in fact plays a crucial role as well. This paper also provides a welfare analysis, the results of which show that government intervention via taxing the locations and subsidizing R&D efforts can remedy the market failure resulting from excess differentiation on locations and under-investment on R&D expenditures in non-cooperative equilibrium. 相似文献

This paper examines the accumulation of physical capital versus knowledge (R&D) capital as a determinant of advanced countries’ comparative advantage. I show that advanced countries are abundant in R&D resources, specialize in knowledge-intensive stages of high-technology industries, and outsource labor-intensive stages of the industries to labor-abundant countries. In contrast, global data on production and trade cannot support the conventional view that advanced countries specialize in and export capital-intensive goods. My results indicate that the accumulation of knowledge capital plays a vital role in explaining advanced countries’ comparative advantage. 相似文献

ABSTRACTThe 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. 相似文献

We estimate the effect of R&D tax incentives on firm-level R&D expenditures (RDE) and patenting using a change in the eligibility criteria for a super deduction in China. In 2006, the Chinese government relaxed the “10 % eligibility criterion”, which stated that only firms with a 10 % or higher increase in prior-year RDE can claim an additional 50 % tax deduction. We use an event study approach to show that firms that became newly eligible to claim the super deduction (those just below the criterion) catches up on RDE and product innovation measured by the sales of new products. In the long run, we also observe a closing gap in the number of patents between the two groups of firms. Moreover, extending tax benefits to all firm helps to lower the tax burden, and we find no evidence of manipulation and relabeling. 相似文献

This study investigates the research and development (R&D) and patenting activities of foreign firms in China. Utilizing a panel dataset of Japanese affiliates during the period 2001–2007, we first examine the determinants of R&D activity and find that local market-oriented firms place more emphasis on R&D, whereas process export-oriented firms are less likely to conduct R&D. Affiliates within a large business group that has more affiliates have a higher propensity to undertake R&D. Using only firms with positive R&D expenditures, we next estimate the patent production function. Results indicate that the patent elasticity of R&D for Japanese affiliates is high, suggesting that they are more productive on patent production than other firms. Moreover, local market-oriented firms do need more patents to protect their products, whereas scientific firms demonstrate a lower willingness to register patents in China. 相似文献

新兴经济体企业的国际化行为已经成为国际商务领域的研究热点之一,但如中国这样的新兴经济体的跨国企业是否能够通过研发国际化行为提升母公司的创新绩效,现有文献对该问题尚缺乏足够的研究。文章基于2011-2017年间沪深两市310家信息技术业上市跨国企业的年度观察数据,采用泊松面板固定效应模型考察了企业研发国际化与母公司创新绩效之间的关系,并首次从逆向知识转移的视角,探讨了吸收能力和地理多样性对研发国际化和创新绩效两者关系的调节作用。实证结果表明:中国企业的研发国际化显著促进母公司创新绩效的提升;以研发投入强度衡量的企业吸收能力显著正向调节研发国际化和创新绩效之间的关系,而以布劳异质性指数测量的地理多样性则显著负向调节研发国际化和创新绩效的关系。研究结果对中国企业国际化行为具有重要启示。该研究发现意味着中国企业在国际化过程中应该加大海外研发投资力度以提升母公司创新绩效,且为更好地实现外部知识的逆向转移,应同时提高企业总体研发投入强度。但作为新兴经济体企业,不宜在地理分布上实行快速扩张,否则较高的沟通和协调成本将弱化逆向知识转移的程度,而不利于母公司创新绩效的提升。 相似文献
