摘　　要：以长江三角洲城市群为例，构建空间效率的指标体系，运用DEA模型测度了1994～2013年长江三角洲城市群的空间效率及2005年、2009年和2013年长三角城市群各地级市的空间效率。基于ESDA空间分析平台，运用局部自相关模型对长三角城市群空间效率空间关联格局进行分析。对长三角城市群空间效率的评价分析发现，阶段性演变过程呈“W”型波动并在波动中上升的特征。空间效率有效的城市数量在逐渐增加的同时空间分异明显，但城市群内个体城市的空间效率差距在不断缩小。聚类特征表现出空间效率与城市规模、行政等级及区位优势等存在一定相关性，空间效率分布与要素集聚程度高度相关。长三角城市群的空间效率表现为明显的非均衡趋势，空间分异的集聚程度加剧。This article took the Changjiang River as an example to build up an index system of spatial efficiency and measured the spatial efficiency in the Changjiang River Delta in 1994-2013 and those of cities in Changjiang River Delta in 2005, 2009 and 2013 by using the DEA model. Based on the analysis of ESDA spatial platform and Local Moran＇s I, the article analyzed the spatial correlation pattern of spatial efficiency in the Changjiang River Delta. The efficiency of the Changjiang River Delta urban agglomeration and its spatial evolution process was in the ＂W＂ type characteristics and rose in volatility. Space efficiency of cities increased gradually while urban space differentiation was obvious, but the individual cities of urban agglomeration spatial efficiency gap was narrowing. Clustering characteristics showed the space efficiency and city scale, and the administrative level and location advantages have a certain correlation. Space efficiency is highly associated with the degree of distribution and factors of agglomeration. Too high or too low element agglomeration size will lower efficiency of urban agglomeration, and factors of agglomeration scale moderation will signifi- cantly promote the efficiency of agglomeration.
