Abstract:

This article took the Changjiang River Delta as an example, built up index system of urbanization efficiency and measured the urbanization efficiency in the Changjiang River Delta from 1990 to 2011 using the DEA model. Based on the analysis of ESDA spatial platform, by using spatial metric model such as spatial correlation index and Local Moran,s I, the article analyzed the spatial correlation pattern of urbanization efficiency in the Changjiang River Delta. The results showed that: 1) Since the 1990s, the urbanization efficiency was overall low but on the rising trend, urbanization pure technical efficiency was entirety higher and on the rise, but urbanization scale efficiency was on the high and weakened as a whole. 2) Urbanization efficiency has a positive correlation characteristics, there existed a spatial cluster feature,it meant that the regions with high urbanization efficiency were apt to be adjacent to the regions with high urbanization efficiency, and the regions with low urbanization efficiency intensity were apt to be adjacent to the regions with low urbanization efficiency. 3) The regions with L-L or H-H correlation pattern had a large percentage since 1990s,and the number of regions were steadily increasing,which reflected the fact that the urbanization efficiency special cluster become more and more obvious. The L-L correlation pattern regions were mainly located in Zhoushan and Taizhou, where the spatial distribution pattern was stable. And the H-H correlation pattern regions were mainly distributed in Suzhou-Wuxi-Shanghai. After 2004, the H-H correlation regions have been increased, converged to Hangzhou and Shaoxing.
