摘要
基于ESDA全局和局部空间自相关分析,利用济南市2000-2007年县域人均GDP数据,对济南市县域总体和局部空间差异的变化趋势进行了初步探索。结果表明,济南市县域经济发展具有明显的空间正相关性,县域经济发展水平在空间上趋于集聚,县域之间的经济增长差异较大。
Exploratory spatial data analysis(ESDA) in analyzing regional economic disparities,ESDA can incorporate spatial effects into the analysis of regional disparities,identifying global and local disparities at the regional scale and visualizing the spatial distribution and patterns through Moran's Scatterplots or maps by means of global and local spatial autocorrelation analyses.This paper investigates the spatial dynamics of regional disparities at the county level in Jinan by analyzing per capita GDP data.Empirical results show strong evidence of spatial autocorrelation at the county level.The results of Moran's and local statistic show that the two types of clusters(high-high and low-low) are increasing which means the heterogeneous is increasing too.
