ANALYSIS OF REGIONAL ECONOMY IN TIME-SPACE DISPARITIES IN CHENGDU-CHONGQING ECONOMIC ZONE
基于成渝经济区130个县的经济数据，用SPSS和GIS分析2000-2007年县域经济实力的空间差异和演变趋势，发现经济差距缩小但仍明显，高发展水平县域沿交通轴分布，成都和重庆的辐射带动作用不足。
Based on the economic development statistics of 130 counties in Chengdu-Chongqing Economic Zone,the paper evaluates the county economic strength by SPSS and GIS.According to the economic strength scores,the 130 counties are divided into four main categories.Then we analyses the spatial differences of county economic strength and its evolution trend from 2000 to 2007.Conclusions as follows:since 2000,the economic disparities of county level have decreased,but still obvious;the economic framework mainly presents concave type,high-level counties are mainly distributed along Chengdu-Deyang-Mianyang highway.urban areas of Chongqing.eastern areas of Chongqing and the zones along the Yangtze river.Most counties are distributed along transport axis such as tributary of the Yangtze river.Railway and highway;Chengdu and Chongqing do not give play to strong points in radiating and driving the surrounding areas making development,so that economic downturn exists in central areas,though Chengdu and Chongqing are dule core of the economic zone;the spatial disparity of county’s economic strength presents sphere structure,following the spatial distance attenuation;spatial agglomeration areas of high-level economic development are constantly expanding,changing from patechy distribution to planar distribution during 2000-2007.
