贵州省人口-经济耦合协调性评价

Evaluation of Population-economy Coupling Coordination in Guizhou Province

基于县域尺度人口-经济系统的指标体系,运用TOPSIS法评价模型和耦合协调模型对近20年贵州省人口-经济协调发展的时空格局进行分析。结果表明,贵州省县域空间存在较大的差异,经济和人口的发展水平呈现出“以贵阳市城区和遵义市城区为高值区-大范围低值区连片分布”的空间特征,贵州省经济和人口子系统、综合发展水平和耦合协调度时间序列变化呈现出先上升后下降的变化趋势。其中,经济发展水平差异大于人口分布差异,近20年,县域耦合协调度呈稳定增长态势的只有8个,表明人口与经济发展的协调程度已成为制约贵州省人口-经济可持续发展的关键。

Based on the index system of the county-scale population-economy system,the TOPSIS method evaluation model and the coupled coordination model are used to analyze the spatial and temporal patterm of the coordinated population-economy development in Guizhou Province in the recent 20 years.The results show that,there are large differences in county space:the development level of economy and population shows"highvalue area and Zunyi and low-value area",the comprehensive development level series changes of economic and population subsystem,comprehensivedevelopment level and coupled coordination degree in Guizhou Province show a change trend of rising first and then decreasing.Among them,the difference of economic development level is greater than the difference in population distribution,in the past 20 years,only 8 counties have grown steadily,indicating that the coordination degree of population and economic development has become the key restricting the sustainable development of population and economy in Guizhou Province.
