吉林省城镇化时空差异及协调发展研究

基于吉林省各县市2005—2014年人口和经济数据,采用探索性空间数据分析(ESDA)方法从整体及局部研究各县市人口城镇化和经济城镇化的时空差异,同时采用协调发展度模型探究城镇化协调发展及空间演化情况。结果表明:吉林省县市间城镇化水平总体空间差异逐步缩小,城镇化发展联系日益紧密;城镇化水平总体空间格局稳定,东西部与中部相比,空间格局稳定且空间差异较小;多数县市在研究前期和中期城镇化发展不协调,末期协调型县市较多,人口城镇化滞后是城镇化发展不协调的主要原因;协调型县市主要分布在东部,不协调型县市主要分布在中西部,县市的协调类型倾向于向更加协调的类型方向变化。

Research on Spatial-temporal Difference and Coordinated Development of Urbanization in Jilin Province

Based on the demographic and economic data of each county and city of Jilin Province from 2005 to 2014,this paper made an overall and concrete analysis on urbanization spatial-temporal difference with ESDA,and analyzed the coordinated development degree of the urbanization with coordinated development model. The results show that:(1)The overall spatial difference of population urbanization level and economic urbanization level grad-ually reduced,and the urbanization development increasingly interconnected. (2 )The overall spatial pattern of population urbanization level and economic urbanization level is stable,the spatial pattern of the middle part is less stable than that of the east and west,and the spatial difference of the eastern and western parts is smaller than that of the middle area.(3)More than half of the regions'urbanization development are not coordinated in the early and middle term,and more regions are coordinated in the final term,population urbanization lagging behind is the main reason for the non-coordinated regions. The coordinated regions are mainly distributed in the eastern part,and the not coordinated ones are mainly in the middle and western parts,the coordination type changed regions tend to be more coordinated.
