长江经济带城市化与农村生态环境耦合协调特征及影响因素研究

Coupling and Coordination Between Urbanization and Rural Ecological Environment in Yangtze River Economic Belt:Study on Characteristics and Influencing Factors

实现城乡统筹和深度融合是中国经济高质量发展的内在要求。分析了长江经济带城市化系统与农村生态环境系统(简称两系统)耦合协调的时空演化特征,并运用面板Tobit随机效应模型对其耦合协调的影响因素进行实证检验。结果表明:(1)2001—2019年两系统耦合度呈现拮抗特征;耦合协调度由期初的中度失调进阶为勉强协调,呈现稳步提升的良好态势。(2)财政支农、农村经济发展、科技创新和政府治理能力对两系统耦合协调关系具有显著正向影响,环境规制对其具有显著负向影响;除政府治理能力外,其余四项因素均呈现显著的地区异质性。(3)从优化财政支农政策、提升政府协同治理能力、聚集科技协同创新要素和定位差异化发展等方面给出政策启示,以期为促进长江经济带生态一体化发展和城乡融合协调发展提供决策参考。

Achieving urban-rural integration and deep integration of urban and rural areas is an inherent requirement for the high-quality development of China’s economy.The paper analyses the spatial and temporal evolutionary characteristics of the coupling and coordination of the urbanization system and the rural ecological environment system(referred to as the two systems)in the Yangtze River Economic Belt,and empirically tests the influencing factors of their coupling and coordination using a panel Tobit random effects model.The results show that:(1)the coupling degree of the two systems presents antagonistic characteristics from 2001 to 2019.The coupling coordination degree has advanced from moderate dissonance at the beginning of the period to slight coordination,showing a good trend of steady improvement.(2)Financial support to agriculture,rural economic development,science and technology innovation,and government governance capacity have a significant positive effect on the coupled and coordinated relationship between the two systems,while environmental regulation has a significant negative effect on them.Except for government governance capacity,all the other four factors show significant regional heterogeneity.(3)Finally,policy insights are given in terms of optimizing financial support policies for agriculture,enhancing the government’s capacity for collaborative governance,gathering elements of scientific and technological collaborative innovation,and positioning for differentiated development,with a view to providing references for decision-making in promoting the integrated ecological development of the Yangtze River Economic Belt and the integrated and coordinated development of urban and rural areas.
