The Enabling Effect of Intellectual Property Strategy on Total Factor Productivity of Enterprises: Evidence from China’s Intellectual Property Model Cities

Does intellectual property (IP) strategy improve the total factor productivity of enterprises (TFP)? This paper uses 21,930 enterprise-year observations of China’s A-share listed enterprises from 2010–2020, adopts a multi-period difference-in-differences model, and constructs a quasi-natural experiment on the impacts of intellectual property model cities (IPMC) on TFP. The findings are as follows: (1) IPMC significantly improves TFP. (2) It has lag effects and long-term effects. (3) The promotion effect is stronger for state-owned enterprises and enterprises implementing organizational political strategies. (4) The close government-business relationship and clean government-business relationship play positive regulating roles in IPMC on TFP. (5) IPMC promotes TFP by increasing urban fiscal expenditure on science and technology and enterprise technological innovation. This study enriches the theory and evidence of policy effect assessment for IPMC at the enterprise level, and provides policy inspiration for the promotion of IPMC and TFP, to help China achieve high-quality economic development.
