摘要 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—2019年A股民营上市企业微观数据,运用双重差分模型考察知识产权制度对民营企业全要素生产率的影响。研究结果表明:与非知识产权示范城市民营企业相比,知识产权示范城市政策显著促进了辖区内民营企业全要素生产率,该结论经过一系列稳健性检验后仍成立。异质性检验显示,知识产权制度对中西部地区民营企业、融资约束较高民营企业及行业竞争程度较高民营企业全要素生产率的正向影响更大;中介效应模型检验表明,知识产权示范城市政策能够通过增加地区科学技术支出和激励民营企业创新产出,进而对民营企业全要素生产率产生积极影响。研究结论揭示了知识产权制度对民营企业全要素生产率的促进作用,为完善知识产权制度、优化营商环境、激励民营企业创新、促进经济实现高质量发展提供借鉴。

Abstract： Taking the national intellectual property demonstration city policy implemented in 2012 as a quasi-natural experiment, this paper selects the micro data of A-share private listed enterprises from 2005 to 2019, and uses the double difference model to investigate the impact of intellectual property system on the total factor productivity of private enterprises. The results show that compared with the private enterprises in non-intellectual property model cities, the intellectual property model city policy significantly promotes the total factor productivity of private enterprises in the area, and the conclusion is still valid after a series of robustness tests. The heterogeneity test indicates that the intellectual property system has a greater positive impact on the total factor productivity of private enterprises in the central and western regions, private enterprises with higher financing constraints and higher degree of industry competition. The intermediary effect model test shows that the intellectual property demonstration city policy can have a positive impact on the total factor productivity of private enterprises by increasing regional science and technology expenditure and encouraging the innovation output of private enterprises. The conclusion reveals the role of intellectual property system in promoting the total factor productivity of private enterprises, and provides reference for improving the intellectual property system, optimizing the business environment, encouraging private enterprises to innovate and promoting high-quality economic development.
Keywords： Intellectual Property   Private Enterprises   Total Factor Productivity   Quasi Natural Experiment   Financing Constraint
