中文摘要：

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2001 年～2011 年长江流域区域经济差异进行分析.结果表明：（1 ）长江流域区域经济绝对差异在波动中持续扩大,而相对差异呈现出迅速缩小的趋势;（2）长江流域市域经济发展水平得到显著提高,空间分布呈现出明显的聚集特征;热点区范围在流域内出现自东向西不断扩散的态势,而以成都城市圈为内环的环状冷点区范围持续收缩;（3 ）长江流域区间差异对流域总体差异贡献最大,虽呈现出缩小的趋势,但仍然是区域经济的主要差异;（4）多元回归模型显示历史经济基础、区域发展策略及地理区位是导致长江流域区域经济差异扩大的主要原因,其中区域发展策略对区域差异的影响程度最深.

英文摘要：

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 Yangtze River Basin (YRB) during 2001-2011 were analyzed from three aspects:time series, spatial series and impact factors.The results showed:(1)the absolute difference continues to expand in fluctuations and the relative difference showing rapid narrowing trend in the YRB;(2)the level of City economic development has been significantly improved and spatial distri-bution showing a characteristics of obvious aggregation;hot-pots appear in the basin have a trend what is from east to west.the cold-spots area ranges con-tinued shrinking where is Chengdu city circle for inner ring;(3)interval dif-ference made the biggest contribution to to the overall differences in the YRB,though showing a narrowing of trend,but is still a major difference in the regional economy;(4)Multiple regression models show that the economic base,the regional development strategy and the location are main reasons that led to the expansion of the YRB’s economic disparities.the regional development strategy is the deepest influence in regional differences.
