摘要
选取2000~2014年重庆市各产业人均产值数据,基于ArcGIS的空间统计模块,采用全局空间自相关Moran's I指数、Getis-Ord Gi~*指数、标准差椭圆方法对重庆市县域产业经济发展的空间差异时空演化进行研究。结果表明,重庆市各县域第二、三产业发展具有显著的空间自相关性,第一产业整体发展变化不大;第二产业整体呈空间扩张的状态;第三产业整体呈空间收缩的状态。
This paper selected the per capita GDP data of Chongqing form 2000 to 2014, based on ArcGIS spatial statistics module, and used global spatial autocorrelation Moran's I index, Getis-Ord Gi~* index, and standard deviation ellipse method to study the spatial difference evolution of county industrial economy in Chongqing City. The result shows that the each county in Chongqing, the secondary and tertiary industry economy development has significant spatial autocorrelation. The overall development of the primary industry changes little, the secondary industry is expanding in space, and the tertiary industry is in a state of contraction.
