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.
