基于ESDA分析的关中城市群县域经济空间分异研究

Spatial variability of county economies in Guanzhong city agglomeration based on ESDA

通过ESDA分析,对关中城市群43个县域2009年的经济总体实力、民生建设水平和经济发展速度进行了分析,揭示了县域尺度上关中城市群经济空间的分异规律,研究表明:1)在经济总体空间格局上,关中城市群在经济总体实力、民生建设水平中存在着全局空间正相关,经济发展速度存在着较弱的空间负相关;2)在经济局部空间格局上,关中城市群的经济总体水平呈现南北两极分化格局,并以西安为核心呈圈级结构,民生建设水平冷点区集中分布在中部,经济发展速度热点区多分布在经济总体实力较低区域;3)关中城市群各县域经济总体实力、民生建设水平和经济发展速度在空间分布上呈现出一定的差异性,主要与各区经济基础、经济区位以及区域发展政策有关。

In this article, taking Guanzhong city agglomeration as an example, we described the spatial variabili- ty of the economies of at county level in 2009 through the analysis of ESDA. Based on the analysis of economic strength, construction of the level of livelihood and development speed, some conclusions were drawn as follows. （1） Considering the overall spatial economies, the county economy of Guanzhong city agglomeration showed strong trend of spatial objective correlation on the index of economic strength and construction level of livelihood.（2） Considering the local spatial economies, the index of economic strength of Guanzhong city agglomeration showed a ＂south - north＂ polarization pattern and the core of circle structure is Xi^n; Besides, the cold spots of construction of the level of livelihood centralize in the central area and the hot spots of development speed dis- tribute the area with low economic level. （3） The reason of different spatial distribution of the three indexes is re-
