江苏省人口城镇化与经济发展时空耦合分析

Spatial and Temporal Coupling Analysis of Population Urbanization and Economic Development in Jiangsu Province

根据人口城镇化与经济发展的相关涵义,构建出人口城镇化与经济发展质量的综合评价指标体系,运用熵值法和耦合协调度等相关数理模型对2000—2014年江苏省人口城镇化与经济发展进行时空耦合分析。研究发现:新世纪以来,江苏省人口城镇化与经济发展之间具有高度相关性,两者相互促进、相互依赖,且人口城镇化与经济发展质量均呈现南高北低、地级市区高于县域的空间分布特征。江苏省人口城镇化与经济发展耦合协调度总体上呈上升趋势;其中,2000—2007年间江苏省人口城镇化滞后于经济发展,2008—2014年江苏省人口城镇化则快于经济发展;在2014年江苏人口城镇化与经济发展两者的耦合协调度在空间格局上呈现明显的区域差异,大致呈现南高北低、地级市区高于县域的地域分异特征。

According to the meaning of population urbanization and economic development and establishing the comprehensive evaluation system of index on the population urbanization and economic development,the spatial and temporal coupling analysis of population urbanization and economic development in Jiangsu Province from 2000 to 2014 was carried out by using the correlation mathematical model such as entropy method and coupling coordination degree. The research showed: Since the beginning of the new century,the population urbanization and economic development in Jiangsu Province had a high degree of relevance and they promoted each other and depended on each other. The quality of population urbanization and economic development in Jiangsu Province all showed the spatial distribution characteristics that the population urbanization and economic development quality in the southern part of Jiangsu were both stronger than those in the northern part,and those in the prefecture-level cities were stronger than those in rural counties. From the time series,the coupling coordination degree of population urbanization and economic development in Jiangsu Province in 2000-2014 was getting higher and higher. In 2000-2007,the population urbanization of Jiangsu Province lagged behind economic development. In 2008-2014,the development of population urbanization in Jiangsu Province was faster than economic development. From the perspective of spatial pattern,the coupling coordination degrees of population urbanization and economic development of Jiangsu Province had obvious regional difference,those in the southern part of Jiangsu were stronger than those in the northern part,and those in the prefecture-level cities were stronger than those in rural counties.
