Coupled Coordination and Obstacle Degree Analysis of Intensive Land Utilization and High-Quality Economic Development:A Case Study of Urban Agglomerations Around Changsha-Zhuzhou-Xiangtan
This paper evaluated the levels of intensive land utilization and high-quality economic development of eight cities in urban agglomerations around Changsha-Zhuzhou-Xiangtan based on the multi-factor comprehensive evaluation method.On this basis,the coupled coordination degree model and relative development degree model were used to explore the temporal and spatial evolution characteristics of the coupled coordination relationship between them,and the obstacle degree model was introduced to analyze the obstacle factors.The results show that:(1)during the research period,the levels of intensive land utilization and high-quality economic development in each city show an upward trend,but the development gap between cities continues to widen;(2)the coupled coordination between intensive land utilization and high-quality economic development in the urban agglomerations tends to be optimized,and the development status has entered a basic coordination stage from the stage of imbalance and decline;the number of cities with synchronous development is constantly increasing,and the two major subsystems have significantly improved;(3)the area of built-up land per capita,foreign exchange income from tourism per capita,the number of households with international Internet per 10 000 people,and the total amount of import and export of goods as a percentage of GDP are the main obstacles to the coordination of land utilization and economic development in urban agglomerations.
