摘要
数字技术创新是数字行业发展的技术支撑,对数字时代下经济社会发展具有重要影响。本文借助于国际专利分类提供的创新活动技术信息,在IPC小组层面识别出数字发明专利,进而构建了数字技术创新数量和数字技术创新质量指标。在此基础上,本文以国务院颁布的《国家信息化发展战略纲要》这一最具代表性的国家政策激励作为切入点,使用2011—2020年中国上市公司面板数据,对政策激励与企业数字技术创新之间的关系展开实证检验。研究结果表明,政策激励对微观主体的数字技术创新数量和质量均有显著的提升效应。异质性检验结果表明,上述提升效应只在民营企业、大规模企业及高科技企业中成立。机制检验表明,缓解融资约束、放松行业准入及促进企业数字技术投资是国家政策激励影响数字技术创新的三个渠道。本文为我国政策激励提供了有益参考,有助于政府制定合理的政策激励微观主体进行数字技术创新。
Digital technology innovation is the technical support for the development of the digital industry and has an important impact on economic and social development in the digital era.International Patent Classification(IPC)at the level of subgroups was used to construct the quantity and quality of digital technology innovation.Based on this,the Outline of National Informatization Development Strategy issued by the Central Committee of the Communist Party of China and the State Council which is the most representative national digital industry policy was taken as the entry point.The panel data of Chinas listed companies from 2011 to 2020 was used to empirically test the relationship between digital industry policy and enterprise digital technology innovation.The results are as follows.The national digital industry policy has a significant effect on the quantity and quality of digital technology innovation of micro-entities.Heterogeneity test results show that the above enhancement effect is only established in private enterprises,large-scale enterprises and high-tech enterprises.The mechanism test shows that easing financing constraints,relaxing industry access and promoting enterprise digital technology investment are the three channels which national policy incentive affect digital technology innovation.It is helpful for the government to formulate reasonable policies to encourage enterprise digital technology.
