Viewing the pilot project of Water Ecological Civilization City Construction as a natural experiment, this study utilized panel data from 278 Chinese cities at or above the prefectural level from 2006 to 2021. It established a Difference-In-Differences (DID) model to investigate the impact of the pilot policy on water ecological resilience and conducted mechanism analysis from the perspectives of advantage transformation and disadvantage compensation. The research findings revealed that the pilot policy of Water Ecological Civilization City Construction effectively enhanced water ecological resilience. This conclusion remained robust even after a series of tests, including parallel trend tests, heterogeneity treatment effect diagnostics, eliminations of other policy interferences, and individual placebo tests. Mechanism analysis indicated that, in terms of advantage transformation, green technology innovation and the construction of water supplied infrastructure play crucial roles in the process of enhancing water ecological resilience in the pilot cities. Concerning disadvantage compensation, the pilot project effectively strengthened the water purification capacity in areas with severe water pollution and improved the water supply capacity in regions with subpar water supply conditions, thereby enhancing water ecological resilience. Based on these research findings, recommendations were put forth for the continued consolidation of the achievements of the pilot project and the ongoing enhancement of urban aquatic ecological resilience capabilities.
