Abstract The imbalance of economic activity and economic phenomenon is a normal status of regional economic. Analysis of regional economic differences and their reasons is very important to accelerate the development of the underdeveloped regions and keep the competitiveness of the developed areas. Based on the correlation analysis of ESDA in the county scale in four years, this paper has made some research on spatial evolution of county economy in the region of Yangtze River Delta since 1978. This paper found out some spatial evolution rules in the region of Yangtze River Delta as follows. Firstly, the general autocorrelation and the pattern of high-low agglomeration are inclined to get increased constantly in the General economic spatial pattern level. In 1978, the spatial distribution of hot spots looks like scattered distribution. In 1988, the distribution of hot spot regions appeared to "一" type, while economy of areas along the Shanghai-Nanjing had a rapid development. In 1998, the distribution of hot spot regions evolving from "一" type to "二" type, while economy of areas along the Shanghai-Nanjing had continue to rapid development, and economy of areas along the Hangzhou-Ningbo also had a rapid development. In 2008, the distribution of hot spot regions evolving from "二" type to "Z" type, while the economy of areas along Shanghai-Nanjing and Hangzhou-Ningbo had Further development, and economic advantages of areas along the Shanghai-Hangzhou also had appeared. Secondly, more randomness and instability of developing state of spatial framework of economic growth has manifested themselves in spatial distribution and hot spot changes frequently, while Moran's I appeared three status in different phases. Thirdly, four elements of economic framework evolvement in Yangtze River Delta have been drawn: historical development basis, economic location, transportation conditions and regional development policies.
