The Spatial Efficiency of The Changjiang River Delta Urban Agglomeration
This article took the Changjiang River as an example to build up an index system of spatial efficien-cy 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 spa-tial 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 evo-lution 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 spa-tial 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 associat-ed 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.
