【摘要】 以2011—2019年全国279个地级市的面板数据为样本，运用熵值法构建城市韧性评价指标体系，运用双重差分法研究海绵城市试点政策与气候适应型城市试点政策协同对城市韧性的影响。主要结论如下：试点政策协同提升了城市韧性，且效果显著优于单一政策试点效果，经过一系列稳健性检验后结论依然成立；进行机制分析发现，试点政策主要通过产业结构升级和公众环境关注度提升促进城市韧性；异质性分析发现，人口规模越大、行政级别越高、防洪等级越高的城市，试点政策协同效果更为明显，但对东、中西部地区城市韧性水平的提升作用不存在明显差异。更多还原

【Abstract】 Based on the panel data of 279 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.更多还原
