RESEARCH ON THE REGIONAL ECONOMIC DISPARITY IN GUANGDONG PROVINCE BASED ON GIS SPATIAL ANALYSIS
利用GIS空间分析方法，基于1990-2004年广东省各市人均GDP数据，研究了区域经济差异的时空变化特征，发现存在显著的空间自相关性和日益扩大的双核结构。
Based on the per capita GDP data of each city from 1990 to 2004 in Guangdong,this paper investigated the regional disparity of economic development of Guangdong Province by using GIS spatial analysis methods.Through calculating the spatial autocorrelation coefficient—Moran's I of per capita GDP of each city,the results show that the economic development of Guangdong Province had a significant spatial autocorrelation characteristic.The results also indicate that the regional disparity of economic development of Guangdong Province is increasing year by year.An obvious dual-spatial structure existed in economic development.Finally,through analyzing the Local Indicators of Spatial Association(LISA) of each year,this paper reveals the characteristics of spatio-temporal change of regional disparity of economic development in Guangdong Province.
