2005—2019年河南省县域经济空间差异及影响因素探测

本文利用Nich指数分析了河南省2005—2019年县域经济发展速率的差异，并采用冷热点分析法分析了经济发展时空格局演化，运用地理探测器分析了河南省县域经济差异的主导影响因子。结果表明，河南省县域经济发展活力与当地经济发展水平在空间分布上基本吻合；县域经济差异呈现两极分化态势，经济发达的城市对周边县域具有辐射带动作用；河南省县域经济发展活力冷热点格局相对稳定，热点区域主要分布在以郑州市、济源市为核心的西北部地区；第二产业增加值、经济基础、人均可支配收入、一般公共预算支出是影响河南省县域经济差异的主导因素，因子交互作用均为双因子增强。

Detection of differences and influencing factors of county economic in Henan province from 2005 to 2019

This paper uses the Nich index to study the differences in the development rate of county economy in Henan province from 2005 to 2019, uses the cold and hot spot model to analyze the evolution of the spatio-temporal pattern of economic development, and uses the geographical detector to analyze the leading influencing factors of the county economic difference in Henan. The results show that the vitality of county economic development in Henan is basically consistent with the local economic development level in spatial distribution, the county economic differences show a trend of polarization, and developed cities have a radiating driving effect on the surrounding counties.The pattern of cold and hot spots of the county economy development in Henan is relatively stable, and the hot spots are mainly distributed in the northwest with Zhengzhou and Jiyuan as the core.
