基于核心—边缘理论的长江上游地区县域发展活力与均衡性动态研究
A dynamic study on development vitality and equilibrium of counties in the upper reaches of the Yangtze River based on core-periphery theory
摘要
Abstract
[Objective]Analyzing the spatiotemporal dynamic characteristics of development vitality and equilibrium in the upper reaches of the Yangtze River is of significant practical and theoretical significance for the high-quality development of the Yangtze River Economic Belt.[Methods]Based on the core-periphery theory,the light Gini coefficient and average light intensity were calculated,and spatial autocorrelation models were used to analyze and characterize the spatiotemporal heterogeneity of development vitality and equilibrium in the upper reaches of the Yangtze River from 2000 to 2020,as well as the'core-periphery'characteristics of both.[Results](1)On the provincial and municipal scale,Chongqing had the highest development vitality,with a growth magnitude of 7.33,and a more balanced development.On the county scale,the average value of development vitality in the upper reaches of the Yangtze River increased by 3.25,while the average value of equilibrium decreased by 0.14,with an overall transition from'significant imbalance'to'gradual balance'.(2)The development vitality and equilibrium of counties in the upper reaches of the Yangtze River exhibited significant'core-periphery'characteristics.In terms of development vitality,Sichuan,Chongqing,and Guizhou were all in the stage of spatial core polarization.In terms of equilibrium,the counties were in the stage of spatial edge diffusion and were gradually evolving towards the stage of spatial dynamic equilibrium.(3)The'core-periphery'characteristics of development vitality and equilibrium of counties had weakened over time,and showed significant differences among provinces and cities.The'core-periphery'characteristics of development vitality were more prominent than those of equilibrium,and it was urgent to take measures to activate the economic development of each county.[Conclusion]There are still significant spatial differentiation characteristics in the development vitality and equilibrium of counties in the upper reaches of the Yangtze River.It is necessary to pay attention to optimizing the spatial structure of regional economy to alleviate the severe differentiation caused by the development of urban agglomerations as the core area.关键词
