摘要
海绵城市建设作为落实水生态文明建设多重目标的关键手段,深入探究其与城市水生态环境之间的关系显得尤为重要。基于中国2010—2020年284个城市的面板数据,采用熵值法测度各城市的水生态环境质量,通过多期双重差分模型探究海绵城市建设试点政策对城市水生态环境质量的改善效应,并运用双重差分倾向得分匹配法进一步进行了验证。研究结果表明:国家海绵城市建设试点实施能够显著地改善城市水生态环境质量,并在一系列稳健性检验下依旧成立;试点政策对城市水生态环境质量的改善效应具有显著的城市和区域异质性,在中东部地区、城市规模较大的城市,试点政策对改善城市水生态环境质量的积极影响更为显著。研究成果对全域推进海绵城市建设以营造美好的城市水生态环境,具有重要的政策效益与学术价值。
As a key means to implement the multiple goals of water ecological civilization construction,it is particularly important to explore the relationship between sponge city construction and urban water ecological environment.The article examines the improvement effect of the pilot policy on urban water ecological environment by using entropy method to measure the water ecological environment quality of each city and through a multi-period difference in differences(DID)method based on panel data from 284 cities in China from 2010 to 2020.The propensity score matching-difference in differences(PSM-DID)model was further validated.The research results indicate that the implementation of the national sponge city construction pilot policy can significantly promote the improvement of urban water ecological environment quality,and remains valid under a series of robustness tests.There is significant urban and regional heterogeneity in the improvement effects of pilot policy on urban water ecological environment.In the central and eastern regions and larger cities,the pilot policy has a more significant positive impact on improving the quality of urban water ecological environment.The research results have important policy benefits and reference value for promoting the sponge city construction throughout the region to create a beautiful urban water ecological environment.
