河南省县域经济发展区域差异及时空格局演变研究

Regional differences and spatiotemporal pattern evolution of county economic development in Henan Province

县域经济是城镇经济和乡村经济的交叉点,也是我国国民经济的重要组成部分。运用加权变异系数和空间自相关分析等方法,探讨了2009—2021年河南省县域经济发展的时空格局演变。结果发现:研究期内,河南省县域经济发展水平不断提高,但增长速率下降明显,县域经济发展差异呈现不断扩大的趋势,区域发展仍不协调;全省县域经济发展呈现从西北向东南的梯次差异,大中城市的辐射作用强,豫南、豫东南的经济塌陷问题显著;河南省县域经济发展总体表现为较强的空间自相关性,经济发展相似的地区在空间上集聚分布。高高集聚区(HH)主要集中在以郑州、焦作为核心的偏西北地区的县域,低低集聚区(LL)多位于周口、驻马店等地市的下属县域。

County economy is the intersection of urban economy and rural economy,and it is also an important component of China′s national economy.By using methods such as weighted coefficient of variation and spatial autocorrelation analysis,this paper explores the spatiotemporal pattern evolution of county economic development in Henan Province from 2009 to 2021.The results show that during this period,the level of county economic development in Henan Province has continuously improved,but the growth rate has declined significantly,and the development gap of county economy has been continuously widening,indicating that regional development is still not coordinated.The county economic development in Henan Province presents a hierarchical difference from northwest to southeast,with strong radiation effects of large and medium-sized cities and significant economic collapse issues in southern and southeastern Henan.The overall performance of county economic development in Henan Province shows a strong spatial autocorrelation,with areas with similar economic development aggregating in space.High-high agglomeration areas(HH)are mainly concentrated in the county areas of the northwest region with Zhengzhou and Jiaozuo as the core,while low-low agglomeration areas(LL)are mostly located in the subordinate county areas of Zhoukou and Zhumadian,among others.
