摘　　要：海绵城市是一种新型的城市发展模式,亦是探索生态文明发展范式的重要尝试。试构建生态韧性指标体系,并基于2006~2020年279个城市的面板数据,通过多期双重差分模型探究海绵城市试点建设对城市生态韧性的影响及作用机制。实证研究发现:海绵城市试点建设显著提升了城市的生态韧性,这种促进作用在降水量不同的城市存在显著的异质性;且技术创新和基础设施投入具有显著的中介效应。在此基础上,提出加强海绵城市建设、提高城市生态韧性的对策建议。Sponge city is a new urban development mode and an important attempt to explore the development paradigm of ecological civilization.Based on the panel data of 279 cities from 2006 to 2020,we constructed an ecological resilience index system and explored the impact of sponge city construction on urban ecological resilience and its mechanism through a staggered DID model.The empirical study found that the sponge city construction significantly improved the ecological resilience of cities,and this promoting effect was significantly heterogeneous in cities with different precipitation endowment.Besides,technological innovation and infrastructure investment had significant mediating effect.On this basis,we put forward policy suggestions to strengthen sponge city construction and improve urban ecological resilience.
