摘要： 强化知识产权保护是完善产权制度的重要内容,对激励民营企业创新具有重要意义。文章以2012年开始实施的国家知识产权示范城市政策作为一项准自然实验,选取2005~2020年沪深A股民营上市公司数据为研究样本,采用多期双重差分模型考察知识产权战略对民营企业创新的影响。研究结果显示,知识产权战略会显著促进民营企业创新,该结论经过一系列稳健性检验后仍然成立。异质性检验表明,知识产权战略对中西部地区、融资约束较高及高技术行业民营企业创新的促进作用更明显。作用机制检验表明,知识产权战略主要通过政府补贴和提升人才集聚作用于民营企业创新。因此,应不断加大知识产权保护力度,持续优化营商环境,激励民营企业研发创新。

Abstract: Strengthening intellectual property protection is an important part of improving the property right system, which is of great significance to stimulate the innovation of private enterprises. Taking the national intellectual property demonstration city policy implemented in 2012 as a quasi natural experiment, this paper selects the data of A-share private listed companies in Shanghai and Shenzhen from 2005 to 2020 as the research sample, and uses the multi-stage double difference model to investigate the impact of intellectual property strategy on the innovation of private enterprises. The results show that intellectual property strategy will significantly promote the innovation of private enterprises, which is still valid after a series of robustness tests. The heterogeneity test shows that intellectual property strategy plays a more obvious role in promoting the innovation of private enterprises in central and western regions, high financing constraints and high-tech industries. The mechanism test shows that the intellectual property strategy mainly acts on the innovation of private enterprises through government subsidies and improving talent agglomeration. Therefore, we should continue to strengthen the protection of intellectual property rights, continuously optimize the business environment and encourage private enterprises to research and innovate.

Key words: intellectual property strategy, innovation, private enterprises, quasi natural experiment, heterogeneity
