摘要: 集约化和提效率对区域经济的高质量发展具有重要意义。基于对土地集约利用与绿色经济效率耦合协调机制的理论梳理,采用全局主成分、超效率SBM、耦合协调度模型和地理探测器等方法,对长江经济带两系统耦合协调关系的时空演化特征和驱动因素进行了系统研究,结果发现:长江经济带土地集约利用与绿色经济效率呈现较高强度的时空耦合关联,区域整体目前仍处于向耦合协调发展的过渡时期,空间上耦合协调度大体自下游向中上游地区梯度递减,处于协调发展状态的地区以上海为核心向江苏、安徽等内陆地区持续拓展。两系统的耦合协调具有多元驱动的复杂性特征,宏观层面的综合解释力呈经济发展>自然禀赋>社会文明的总体格局,产业结构和人口密度是驱动二者高质量协调发展的主导因素,社会文明进步则是区域资源优化配置和可持续发展的基础保障。当前,要因地制宜优化资源配置,加强区际间协调联动,共同促进区域整体的均衡高质量发展。

Abstract: Intensive land use and efficiency improvement are of great significance to the high-quality development of regional economy.Theoretical analysis of the coupling and coordination mechanism of intensiveland use and green economic efficiencywas performed. The methods of global principal components, super-efficiency SBM, coupling coordination degree model and geographic detector were used to analyze the spatial-temporal evolution characteristics and the coupling coordination relationship between the two systems in the Yangtze River Economic Belt. The driving factorsand the green economic efficiency showed a relatively strong spatial-temporal coupling correlation. The gradient decreased towards the middle and upper reaches. The areas in a state of coordinated development was continuingto expand to inland areas of Jiangsu and Anhui with Shanghai as the core. The coupling and coordination of the two systems was characterized by the complexity of multiple drives. The comprehensive explanatory power at the macro level was the overall pattern of economic development > natural endowments > social civilization. Industrial structure and population density werethe leading factors driving the high-quality coordinated development of the two systems. Civilization progress was the basic guarantee for the optimal allocation of regional resources and sustainable development. It is necessary to optimize resource allocation according to local conditions, strengthen inter-regional coordination and linkage, and jointly promote the balanced and high-quality development of the region as a whole.
