| 中文摘要 |
| 绿色发展是推动我国生态环境治理体系现代化与实现经济社会全面转型的关键战略. 基于投入-产出框架，从降碳、减污、扩绿、增长协同视角构建绿色发展绩效评估体系，采用超效率SBM模型测度2012~2023年长三角27市绿色发展绩效，并结合核密度估计与Dagum基尼系数分解法分析其时空演化规律. 结果表明：①本研究期内，长三角绿色发展绩效整体呈“先降后升”趋势，均值从0.598波动上升至0.877，增幅达46.66%. ②省域层面，浙江和安徽在本研究初期绩效优势明显，但提升速度缓慢，而上海、江苏绿色发展绩效在本研究期内显著提升. 城市层面，绍兴和池州等6市绿色发展水平在本研究期始末均处于效率前沿面，无锡、常州、苏州和嘉兴等城市增幅最大，而铜陵、芜湖绿色发展绩效出现下降. ③长三角绿色发展绩效的城际差异在本研究期内有所缓解，总体基尼系数由0.248降至0.125，其中省内差异是整体差异的主要来源. 基于实证结果，从经济发展水平和绿色发展绩效两个维度构建四象限图，据此提出不同城市绩效提升的差异化路径，并从政策协同、产业协作、生态联治和科技共享等方面提出绿色协同保障机制. |

| Green development is a key strategy to promote the modernization of our ecological and environmental governance system and realize the comprehensive transformation of the economy and society. Based on the input-output framework， a green development performance evaluation system is constructed from the perspective of carbon reduction， pollution reduction， and green growth synergy， and the green development performance of 27 cities in the Yangtze River Delta Region from 2012 to 2023 is measured by using the super-efficient SBM model. The spatio-temporal evolution law is also analyzed by combining kernel density estimation and the Dagum Gini coefficient decomposition method. The results show that： ① During the study period， the overall green development performance of the Yangtze River Delta Region showed a trend of “first decreasing and then rising，” with the average fluctuating from 0.598 to 0.877， an increase of 46.66%. ② At the provincial level， Zhejiang and Anhui had obvious performance advantages at the beginning of the study period， but the improvement rate was slow， while the green development performance of Shanghai and Jiangsu increased significantly during the study period. At the city level， the green development level of six cities including Shaoxing and Chizhou has always been at the forefront of efficiency， with Wuxi， Changzhou， Suzhou， Jiaxing， and other cities increasing the most， while the green development performance of Tongling and Wuhu in Anhui has declined. ③ The intercity differences in green development performance in the Yangtze River Delta Region eased during the study period， and the overall Gini coefficient decreased from 0.248 to 0.125， of which intra-provincial differences were the main source of the overall differences. Based on the empirical results， a four-quadrant diagram is constructed from the two dimensions of economic development level and green development performance； the differentiated paths for performance improvement in different cities are proposed； and a green collaborative guarantee mechanism is proposed from the aspects of policy coordination， industrial collaboration， ecological joint governance， and science and technology sharing. |
