With the aid of ArcGIS and GeoDa, the study measured by the index of PCGDP with the methods of statistic analysis and ESDA. Regional economic disparities in Chengdu-Chongqing Urban Agglomeration since 2000 were analyzed from three aspects: time series, spatial series and impact factors. The re-sults showed:(1)In Chengdu-Chongqing Urban Agglomeration,the absolute differ-ence continues to expand in fluctuations and the relative difference showing fluctuate narrowing trend, the high economic value gathering area is relative-ly stable and have obvious radiation effect;(2)The space overall pattern is east-west of country economy in Chengdu-Chongqing Urban Agglomeration, the e-conomic center of gravity gradually tends to the geometric center of gravity, economic development in both the main and secondary direction of a sustained expansion; regional economic level has been significantly improved, the forma-tion of the dual core structure in the high level country, the low level grad-ually narrowed and mainly distributed in the marginal mountainous counties;the hot spots of economic development in the region are relatively stable and have a certain diffusion effect, while the cold spot is a product word distri-bution but its scope continues to shrink;(3)The adjustment of industrial structure, regional development strategy, market development and population growth are the main cause of expansion of Chengdu-Chongqing regional economic difference, but the influence of industrial structure adjustment and popula-tion growth on regional differences are relatively profound.%利用传统统计方法和ESDA方法,在ArcGIS和GeoDa等软件的支持下,以人均GDP为测度指标,从时间、空间及影响因子三个方面对2000年以来成渝城市群区域经济差异进行分析.结果表明:(1)成渝城市群区域经济绝对差异在波动中不断扩大,相对差异呈波动下降趋势,区内经济高值集聚区相对稳定,辐射带动作用明显;(2)成渝城市群县域经济空间总体呈东-西向格局、经济重心逐步趋于区域几何重心,经济发展在主要及次要方向上均呈现出持续扩张状态;区域经济水平得到显著提升、高水平县域形成"双核组团"结构、低水平范围逐步缩小且主要分布在边缘山地县域;区内经济发展热点区相对稳定并呈现出一定的扩散效应,而冷点区呈"品"字状分布但其范围持续缩小;(3)产业结构调整、区域发展策略、市场发育状况和人口增长状况是导致成渝区域经济差异扩大的主要原因,而产业结构调整和人口增长对区域差异的影响相对深刻.
