As a demonstration area for the implementation of the national intellectual property strategy,the intellectual property demon-stration city plays an important role,and the intellectual property strategy also has positive significance for the digital transformation of en-terprises.Based on the data of A-share listed companies in Shanghai and Shenzhen Stock Exchanges from 2008 to 2021,this paper uses the staggered difference-in-difference model(DID)to verify whether intellectual property strategy has an impact on enterprises'digital transformation.The results show that the intellectual property strategy can significantly empower the digital transformation of enterprises,and the conclusion is still valid after several robustness tests such as parallel trend and dynamic effect test,placebo test and propensity score matching.From the perspective of the mechanism of action,intellectual property strategy can significantly empower enterprises'dig-ital transformation through the promotion effect of property rights subsidies and the incentive effect of property rights innovation.
