政府补贴对高新技术企业创新的促进效果研究

Research on the Promotion Effect of Government Subsidies on Innovation of High-Tech Enterprises

政府补贴作为产业政策中的重要一环,往往被用于促进高新技术企业的研发创新。迄今为止,政府补贴对企业创新产出的促进效果仍未达成共识。基于上海科技创新中心建设的主要载体——张江国家自主创新示范区,文章实证研究了政府补贴对于创新产出的激励效果。结果表明:第一,政府补贴总体上显著提高了高新技术企业的研发创新产出;第二,政府补贴对于小规模企业以及非国有企业研发创新产出的促进效果更明显;第三,政府补贴对创新产出的促进效果,可能来自于提高科技经费投入、加大科技人才引进力度以及吸收外部先进创新技术这三方面作用机制。

As an essential component of industrial policy,government subsidies are frequently utilized to encourage RD innovation in high-tech companies.There is currently no unanimity regarding the impact of government subsidies on the innovation output of businesses.This paper empirically investigates the incentive effect of government subsidies on innovation output,using the data from Zhangjiang National Innovation Demonstration Zone,which is the main vehicle for Shanghai's science and technology innovation center construction.We show that government subsidies significantly increase the RD innovation output of high-tech enterprises in general.We also prove that government subsidies would promote the RD innovation output of small-scale enterprises and non-state-owned enterprises more considerably.Besides,the promotion of government subsidies on innovation output may result from three mechanisms:increasing investment in science and technology,upgrading the investment in science and technology talents,and absorbing innovative external technologies.
