基于空间统计分析的辽宁省县域经济空间差异研究

STUDY ON SPATIAL VARIABILITY OF INTRA- COUNTY ECONOMIES IN LIAONING PROVINCE BASED ON SPATIAL STATISTICAL ANALYSIS

以辽宁省44个县域为研究单元,通过对2008年各县域经济的总体实力、平均水平及发展速度3项指标值的定量计算,应用空间统计分析方法对辽宁省县域经济空间差异进行了研究,揭示了县域经济差异的空间自相关特征。研究表明:辽宁省县域经济的总体实力、平均水平和发展速度三项指标均存在显著全局空间正相关性,县域经济差异空间聚集显著;Moran散点图显示多数县域位于第一、三象限内,LL型较多,非典型县域数量较少,空间分布不均衡;总体实力和平均水平两个分析指标的局部自相关性显著,呈现出"东部—中部—西部,南部—中部—北部"逐级降低的空间分布特征,发展速度呈现出两个热点区,分别为西部和中北部地区。

Used 44 counties in Liaoning province as study unit,this paper quantitatively calculates the overall strength,average level and development speed characteristic value in 2008,studied Spatial variability of intra-county economies in Liaoning Province by Spatial Statistical Analysis and revealled the spatial autocorrelation for intra-county economies.The results shows that there are great differences among the Intra-county economies and have positive correlation of global spatial autocorrelation during the overall strength,average level and development speed;most counties are located in first quadrant and third quadrant,LL type is in the majority while Atypical counties is seldom;The local spatial autocorrelation has positive correlation,the overall strength and average level shows that The spatial distribution characteristics reduced step by step among ＂east-middle-west,south-middle-north＂,the development speed shows two hotspots,respectively west and north-central region.
