数字创新与产业政策选择:基于政策工具组合视角

Digital Innovation and Industrial Policy Choice:From Perspective of Policy Instrument Portfolio

文章选取2013—2019年中国沪深A股数字经济企业为研究样本,基于政策工具组合视角来考察促进数字创新的产业政策实践问题。研究发现,政府补贴、税收优惠对数字创新存在显著影响,其均能促进数字创新,但两者的组合实施与预期的目标政策结果存在差异,政策工具的组合实施导致了挤出和替代效应。影响机制分析发现,企业存在寻租行为,证实了企业在一定程度上不会将获得的补贴全部用于创新研发。进一步地,考察了政策工具组合对数字创新存在的行业、空间、规模异质性影响。

Based on the research samples of Chinese A-share digital economy enterprises in Shenzhen and Shanghai from 2013 to 2019,this paper investigates industrial policy practices to promote digital innovation from the perspective of policy tool portfolio.The results show that government subsidies and tax incentives have a significant impact on the technological innovation of digital economy enterprises,both of which can promote the digital innovation ability of enterprises.However,the combined implementation of the two is different from the expected target policy results,and the combination of policy instruments leads to crowding out and substitution effects.The analysis of the influence mechanism finds that enterprises have rent-seeking behavior,which confirms that enterprises will not use all the subsidies obtained for innovation research and development to a certain extent.Further,the paper examines the impact of policy Instrument Portfolio on the heterogeneity of industry,space and scale of digital innovation.
