The Impact of Artificial Intelligence Demonstration Zone Policies on the Green Innovation Resilience of Manufacturing Firms

Using firm-level panel data from Chinese A-share-listed manufacturing firms over the period 2019–2024, this study exploits the staggered implementation of the National New-Generation Artificial Intelligence Innovation and Development Demonstration Zones as a quasi-natural experiment. A multi-period difference-in-differences (DID) framework is employed to identify the causal effect of AI demonstration zone policies on firms’ green innovation resilience, while further investigating the underlying mechanisms and heterogeneous effects. The empirical results indicate that the establishment of AI de
