政府补贴、国际知识产权保护与企业创新——来自战略性新兴产业上市公司的证据

政府补贴对企业创新的影响存在争议,在美国重点打击中国战略性新兴产业的背景下,补贴这一产业政策的有效性再次引起热议。本文以2012-2017年沪深A股战略性新兴产业上市公司为样本,研究在国际知识产权保护加强的背景下政府补贴对战略性新兴产业创新绩效的影响。研究发现:中国政府实施的补贴政策有利于促进战略性新兴产业创新,但国际知识产权保护加强约束了中国政府补贴的规模和空间,从而抑制了补贴政策对战略性新兴产业创新的激励作用;此外,基于企业和产业异质性视角,国际知识产权保护的加强主要抑制了补贴对国有企业、内资企业和新材料产业创新的促进作用。进一步完善补贴政策和国内的知识产权保护制度,有利于提升中国在构建国际经济新秩序中的话语权。

Venture capital,innovation, and growth: evidence from Chinese metropolitan data

Using panel data from 282 Chinese cities from 2003 to 2015, we estimate the impact of venture capital (VC) on innovation, employment, and payroll in metropolitan areas. Controlling for endogeneity, VC investments are significantly positively related to metropolitan innovation, employment, and payroll in a fixed effects panel regression and dynamic GMM estimation. Using the number of IPOs (Initial public offerings) in the city as an instrumental variable to again control for endogeneity, VC remains significant. Our results show that VC is significantly contributing to the metropolitan economy as a whole by supporting innovation, creating jobs, and generating wealth in the local cities.     

Vertical differentiation,product innovation,and dynamic competition

This paper presents an infinite horizon dynamic model in which two firms compete in a market vertically differentiated by the qualities of their products and consumers have heterogeneous preferences for quality. Given the product qualities offered, the firms engage in price competition that segments the market. In each period each firm can spend on product innovation that if successful increases the quality of its product. Three types of Markov perfect equilibria are identified. A running–coasting equilibrium exhibits increasing quality dominance with one firm undertaking innovation and the other coasting to free ride on the innovation by the first firm. The firm that coasts can have the larger dynamic payoff, so quality dominance does not imply payoff dominance. A second is a leap‐frog equilibrium in which the trailing firm undertakes innovation to leap into the lead. The trailing firm never innovates solely to narrow the gap with the leader, so catch up strategies are never used. In the third both firms undertake innovation, but if both have innovation successes, product differentiation remains the same and profits are reduced by the cost of innovation. The rivalry between Intel and AMD in microprocessors for personal computers provides a motivating example.

Tax incentive,R&D investment and firm innovation: Evidence from China

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.     

社会资本能否抑制僵尸企业的创新挤出效应？——基于制造业上市公司的经验证据

以制造业上市公司为样本，探讨社会资本能否抑制僵尸企业对健康企业创新的挤出效应。结果显示：僵尸企业每增加1%，健康企业的发明专利数降低0.41%。僵尸企业的创新挤出效应大部分由非国有企业承担，国有企业的创新并未受到影响。健康企业通过积累不同类型的社会资本来抑制僵尸企业对其创新造成的挤出效应。非国有健康企业的连结型社会资本对创新挤出效应的抑制作用最强，结合型社会资本的作用次之，桥接型社会资本的作用最小。

Can interfirm trust improve firms' cooperation on environmental innovation? The moderating role of environmental hostility

Based on the logic of “trust‐behavior,” we examined the relationship between interfirm cognitive trust, emotional trust, and firms' cooperation on environmental innovation, as well as the moderating role of environmental hostility on the relationship between two dimensions of interfirm trust and cooperation on environmental innovation. Data for the study were collected from 216 firms in China. The results indicated that both interfirm cognitive trust and emotional trust were positively correlated to firms' cooperation on environmental innovation, and the effect of emotional trust on firms' cooperation on environmental innovation was negatively moderated by environmental hostility. Finally, the results were discussed and future directions put forward.
