摘　　要：基于复合指标视角,全面认识和提高城市发展质量,是推进长三角城市群实现高质量一体化发展的有效途径。论文从经济、社会、科教、设施、环境等5个维度出发构建城市发展质量评价指标体系,定量测度城市发展质量,分析2008—2018年城市发展质量时空演变格局。结果显示:(1)长三角城市群城市发展质量加速提升,但仍然存在差距,且各项城市发展质量呈现非均衡性;(2)上海市发展质量平均得分最高,三省一市平均得分差距不断缩小,表明长三角城市群城市发展质量具有显著的绝对收敛趋势;(3)城市发展质量平均中心经历了分散→集聚→分散的动态演化过程,其中经济发展质量平均中心位移最大,科教发展质量平均中心位移最小。移动轨迹大多呈现"先西后东、整体向西,先北后南、整体向北",说明城市发展质量提升速度西部高于东部,北部高于南部。Based on the perspective of composite indicators,comprehensively understanding and improving the quality of urban development is a scientific issue that reveals the high-quality integrated development mechanism of urban agglomerations in the Yangtze River Delta.This paper constructed an urban development quality evaluation index system from five dimensions:Economy,society,scientific and education,facilities,and environment to quantitatively measure the development quality of 26 cities,and analyzed the evolution of spatiotemporal pattern of urban development quality in 2008,2013 and 2018 in detail.Research shows that the comprehensive urban development quality in Shanghai is higher than that of the other 25 cities,which followed by Nanjing and Hangzhou.The cities with the lowest comprehensive development quality in three years are Chaohu,Xuancheng,and Anqing.Although the development quality has been continuously improved,the growth rate in 2013—2018 is even faster.There is a significant imbalance in the subitem development quality,especially in Shanghai,Nanjing,Hangzhou,Hefei,Wuxi and Zhoushan.The quality of economic,social,scientific and educational development is high,but the quality of facilities and environmental development is very low.From the perspective of the spatiotemporal evolution pattern,the average center of urban development quality in the Yangtze River Delta urban agglomeration deviates eastward from the regional geometric center and has undergone a dynamic process of decentralization-aggregation-decentralization.
