Climate Change Risks and Urban Resilience Enhancement:Based on the Synergetic Perspective of Pilot Projects in Sponge Cities and Climate Adaptive Cities
Based on the panel data of279 prefecture-level cities in China from 2011 to 2019,the entropy method is used to construct an evaluation index system of urban resilience,and the double-difference method is used to study the impact of the synergy of the sponge city pilot policy and climate-adaptive city pilot policy on the resilience of cities.The main conclusions are as follows:the collaborative pilot policies have improved urban resilience,and the effect is significantly better than that of a single policy pilot,and the conclusion is still valid after a series of robustness tests.Mechanism analysis shows that pilot policies promote urban resilience mainly by upgrading industrial structures and enhancing public environmental concerns.Heterogeneity analysis found that cities with larger population sizes,higher administrative levels,and higher flood control levels have more significant synergistic effects of pilot policies;but there is no significant difference in improving urban resilience in the eastern,central,and western regions.
