Urban ecological resilience is the key to supporting ecological civilization construction and urban sustainable development.Based on the panel data of 285 prefecture-level cities in China from 2007 to 2023, this paper uses the progressive difference-in-difference model, double machine learning and a series of robustness tests to study the effect, transmission mechanism and heterogeneity of the pilot policy of“comprehensive demonstration city of energy-saving and emission-reduction fiscal policy”on urban ecological resilience.The study found that:the“energy conservation and emission reduction”policy can significantly improve the urban ecological resilience, and the positive impact of the policy remains robust after multiple tests.The policy effect is transmitted through the three-level path of“central-local coordination, government-enterprise linkage, and government internal drive”,the central-local coordination has the greatest impact, followed by government-enterprise linkage, while the government internal drive is limited by local financial constraints and traditional performance appraisal orientation, and the effect is relatively weak.In the heterogeneity analysis, the policy empowerment effect of cities south of the Hu Huanyong Line, key environmental protection cities and cities with a net population inflow is more prominent.The research provides theoretical support and practical reference for improving the fiscal policy system, optimizing regional ecological collaborative governance, and formulating ecological resilience improvement strategies that adapt to different urban characteristics.
