Abstract: In the context of complex and volatile global economic situation and insufficient growth drivers, exploring how to enhance economic resilience has become an important issue. The existing literature mostly focuses on the impact of traditional economic stimulus policies on short-term economic fluctuations, but pays less attention to the role of institutional innovation in cultivating long-term economic resilience. Based on the panel data of 276 prefecture-level cities in China from 2008 to 2021, this paper empirically tests the impact of the construction of intellectual property demonstration cities on economic resilience by using the multi-period DID method. The study finds that the policy has significantly promoted the urban economic resilience, and the conclusion is still valid after a series of robustness tests. The mechanism analysis shows that the construction of intellectual property demonstration cities not only directly promotes the economic resilience by strengthening the government's innovation leading role and optimizing the talent magnetic field effect, but also further synergize with the regional digital level and business credit environment to form a more effective policy effect. Heterogeneity analysis shows that sub-provincial level and super megacities are more likely to play a role in promoting policy implementation. This paper provides a new idea for understanding the formation mechanism of economic resilience, and provides a basis for decision-making to enhance the regional adaptability of intellectual property policies.
