中原经济区县域经济空间格局演化研究

为深化对中原经济空间发展格局的认识，为中原经济区经济的持续、健康发展提供决策参考，该文将中原经济区232个县域作为研究对象，选取人均GDP为评价指标，采用探索性空间统计分析方法对2000—2014年中原经济区县域经济空间结构的全局和局部演变特征进行了研究。结果表明:2000—2014年中原经济区县域经济总体差异呈扩大—缩小—扩大的趋势；县域人均GDP呈显著的正的空间自相关，县域经济在空间上聚集分布；县域经济的局部空间分布主要表现为HH聚集模式，变化较小，形成了以中西部的郑州—洛阳和北部的武安市—邯郸市峰峰矿区、高唐县—荏平县为中心的三个HH集聚区，经济引擎作用明显，LL区主要分布在东南部的亳州市和阜阳市，其集聚态势先增强后减弱，HL区和LH区相对较少，且没有明显的分布规律。

Study on the Economic Spatial Pattern at County Level in Central Plains Economic Region

In order to deepen the understanding of the Central Plains Economic Region (CPER) economic space development pattern and provide decision-making reference for the sustained and healthy development of CPER, per capita GDP was selected to be the evaluating indicator. We use ESDA analyzing method to explore the evolution characteristics of global and local economic spatial structure at the county level in CPER from 2000 to 2014. The domestic economy of CPER showed the trend of expanding-narrowing-expanding at global level during the period from 2000 to 2014. The domestic per capita GDP is positive and significantly spatial autocorrelation, while the local economic shows aggregating spatial pattern. Local spatial distribution of the county economy is HH aggregation model with little changes, forming three HH concentrated centers:Zhengzhou—Luoyang, Wuan—Fengfeng mining area and Gaotang—Renping with obvious economic engine effect. LL area mainly distributs in the southeastern of Bozhou and Fuyang. Its agglomeration trend goes enhancing at first and then weakening. The HL and LH areas are relatively small and have no obvious distribution patterns.
