On the basis of spatial-temporal perspective, by using the data of farmers’ net income per capita from 1996 to 2007 in counties of Guangxi coupled with the global and local spatial autocorrelation analysis of ESDA and GIS technology,we conduct the empirical research on the rural economic developmental disparity of counties in Guangxi and the evolving characteristics of local spatial heterogeneity. The results show that the rural economic developmental disparity of counties in Guangxi from 1996 to 2007 varies infinitesimally on the whole ,and the regions with similar rural economic developmental level have spatial concentrated distribution. Based on these,the local Moran’s I scatter diagram and LISA concentration diagram are drawn. In comparison with the traditional analytical method, the spatial analytical method of ESDA-GIS can explain the problem of spatial heterogeneity of rural economic development clearly, and have direct visual effect.%从时空角度出发,利用广西各县(市)1996～2007年人均农民纯收入数据,结合ESDA全局和局部空间自相关分析方法与GIS技术,对广西县域农村经济发展差异和局部空间异质性的演变特征进行了实证研究.结果表明,1996～2007年,广西县域农村经济空间差异总体变化不大,农村经济发展水平相似的地区在空间上集中分布,并在此基础上绘制了局部Moran's Ⅰ散点图和USA集聚图.相对于传统分析方法,ESDA-GIS空间分析方法可以清楚地解释农村经济发展空间异质性问题,并具有直观的可视化效果.
