湖北省县域经济空间分异与优化研究

基于湖北省2009年县域经济发展数据,采用主成分分析和空间分析等方法,对县域经济发展的空间特征进行综合分析。结果表明:湖北省县域经济呈现"双核结构""、金字塔结构""、圈层结构"和"点-轴结构"空间特征,省内发达县域(第一、二圈层)位于"宜昌市和武汉市"两个内核周边,沿长江、沪蓉高速、京广、京九、焦枝铁路等轴线集中;第三圈层位于江汉平原核心和东部,第四圈层位于省际边缘区;从空间上看,湖北省县域经济形成小范围的"高-高"集聚,但不存在明显的"低-低"聚集,出现聚积发展型、极核发展、均衡发展、边缘发展四种类型。根据分析,本文提出建设武汉-荆州都市连绵区、打造宜昌市和襄樊市城市增长极点、强化"两轴四线"、加快鄂西县域综合开发等县域经济空间优化路径。

Research on Space Disparities and Optimization of County Regional Economy in Hubei Province

Based on the economic development statistics of Hubei Province in 2009,the essay has comprehensively analyzed the space characteristic of county regional economic development in Hubei Province by using Principal Component Analysis and Spatial Autocorrelation Analysis method.The result shows that the county regional economy in Hubei Province appears to have "dual-nuclei structure","pyramid structure","the circle structure",and "pole-axis spatial" characteristics.The developed counties(the first and second circle) are around "Yichang City and Wuhan City" as well as along the Yangtze River,Shanghai-Chengdu expressway,Beijing-Guangzhou,Beijing-jowloon,Jiaozhi railway;the third circle is located in the central and eastern of Jianghan plain,and the fourth circle is located in the edge of the province.From the point view of the space,the county regional economy has "high-high" concentration,but lacks in obvious"low-low"concentration.There are four types of development,including concentration development,pole-nuclei development and equilibrium development,edge development.According to the analysis,this paper puts forward the space optimal path of county regional economy in Hubei Province,which suggests to construct the Wuhan-Jingzhou megalopolis,make Yichang and Xiangfan city to be the urban growth poles,strengthen the "two-axis four-wire" and accelerate the comprehensive development of the county in western Hubei Province.
