云南沿边地区县域经济的空间格局演化分析

基于云南沿边地区56个县域单元1993,2002,2009,2015年人均GDP数据,运用ESDA-GIS方法分析沿边地区县域经济的空间演化格局,并探讨其驱动因素。结果表明:云南沿边地区县域经济发展和区域经济增长存在正的空间自相关,但相关性相对较弱。1993年以来,县域经济整体格局变动不大,经济热点区域始终处于弥勒、建水、蒙自等县市,冷点区域则始终处于广南、麻栗坡、绿春等县域;而经济增长格局则表现出明显的空间演化和跃迁特征。整体上看,云南沿边县域经济的空间差异较大,由随机成分造成空间异质性也逐渐增强,且东—西方向上县域经济差异有进一步扩大趋势。资源禀赋、地理区位以及区域发展政策是县域经济空间格局演化的主要驱动力。

Spatial Pattern Evolution Analysis of Economy at County Level in Yunnan's Border Areas

Yunnan's border area contains 56 counties or cities, is the periphery area of Yunnan economic zone.Based on the 56 counties' per capita GDP of the relevant years, this paper analyses the evolvement of spatial-temporal pattern at county level and explores the possible drive factors behind changes in the spatial pattern by use of ESDA-GIS.County-level economy development and regional economic growth in the border areas exhibit a positive spatial autocorrelation character, but the correlation is relatively weak.Since 1993, the change of county-level economy development pattern in the borders areas is not big, the hotspot areas of economic development mainly clustered in counties of Mile, Jianshui, Mengzi etc, while the coldspot areas were concentrated in counties of Guangnan, Malipo, Lvchun etc.And the economic growth pattern in space shows obvious characters of spatial evolution and transition.In view of the overall situation, county-level economy along the border areas has big spatial differences, but with the economic development, this space heterogeneous caused by random element also gradually increase.While the county-level economic disparities of east-west will possibly further extend.The main driving force of spatial pattern evolution of the county-level economic framework can be identified through the three aspects of resource endowment, geographical location and the policies on regional development.
