长江经济带新型城镇化时空格局演变及影响因素研究

Study on the spatial-temporal pattern evolution and influencing factors of the new urbanization in the Yangtze River Economic Belt

从经济、人口、社会发展、基础设施、城乡统筹和生态环境等6个方面建立新型城镇化发展水平的评价指标体系,运用熵值法、空间自相关分析法和灰色关联分析法等方法对长江经济带2003年、2009年和2014年110个地级及以上城市新型城镇化水平的时空格局及影响因素进行分析.结果表明:1)长江经济带市域间新型城镇化水平差异明显,西部差异大于中部大于东部;2)新型城镇化水平整体呈现出波动上升的态势,从东西方向上看,东部发展水平较稳定,中西部发展水平波动明显;3)新型城镇化中高、中等、中低和低水平区都呈现显著的空间集聚状态,但低水平区的连续分布状态有逐渐被"冲散"且面积减小的趋势;4)长江经济带新型城镇化水平五个类型区的影响因素各异,总体差异较显著.

The evaluation system of new urbanization is established in the article,which is composed of six subsystems：economy,population,social development,infrastructure,urban-rural integration and ecological environment.With the Entropy method,Spatial auto-correlation analysis and Grey correlation analysis,this article analyze the spatial-temporal evolution pattern of the new urbanization and its influencing factors of Yangtze River Economic Belt＇110prefecture-level cities in 2003,2009 and 2014.Results show：firstly,the spatial disparity of the new urbanization level is remarkable among 110 cities,which is larger in the western region than in the middle-eastern region;secondly,the level of new urbanization shows a fluctuant increasing progress,which is relatively stable in the eastern region,while fluctuates significantly in the middle-western region;thirdly,the spatial-correlation state of new urbanization level shows a significant positive correlation while the continuous distribution state of low level region has gradually been broken up with its distribution range decreases;fourthly,the influencing factors of the five types are different,and the difference is significant.
