中原经济区县域经济发展空间格局及演变

Spatial Pattern Change of the County Scale Economic development in Central Plains Economic Region

通过空间自相关分析方法对2000年以来3个时间断面县域经济发展数据进行分析,描述了中原经济区范围内县域经济发展空间格局变化状况,并分析其演化影响因素。结果显示:12000年以来中原经济区经济发展水平空间格局局部区域变动较大,但总体格局相对稳定,呈现西高东低态势;30个省辖市市区成为辐射中原经济区整体县域经济发展的极点;市区近郊县域具有二元经济特征。2经济发展空间集聚格局较为明显;热点区呈现双核结构;次热点区围绕热点区分布,圈层结构明显,呈现核心—边缘模式。3通过影响因素分析得出经济发展空间格局的变动是历史基础、农业资源、区位条件和区域政策综合作用的结果。

Through analyzing the three time periods of county economic level data since 2000 by spatial analysis technology, this paper explores the spatial pattern change and its influence factors of CPER＇s county economic development. It shows that：1 Though the spatial Pattern of economic level has changed a lot in CPER＇s local area, the overall pattern is relatively stable, and presents a＂high west, low east＂distribution. 30 municipal districts become growth poles which radiate the CPER＇s county economic development and the characteristic of point- axis is obvious. The counties which near municipal districts have dual economic feature. 2Economy at the county level in CPER has spatial autocorrelation and high value clustering phenomenon, hotspots showing dual- nuclei spatial structure. Sub- hotspots distribute around the hotspots, and the feature of layer structure is significant, showing core- periphery model. 3 The Spatial Pattern Change of the economic development is caused by the comprehensive role of historical basis, agricultural resources, location, regional policy.
