产业一体化与城市土地利用效率的时空耦合效应 ——以长江中游城市群为例

研究目的:揭示并分析产业一体化与城市土地利用效率间的耦合交互关系,从空间效应视角探寻两者协调发展路径。研究方法:SVR算法、耦合协调模型、空间相关分析。研究结果:(1)产业一体化与城市土地效率间存在彼此影响、相互约束的耦合协调关系;(2)2003—2015年间长江中游城市群各城市产业一体化与城市土地利用效率的耦合协调度呈现波动上升趋势,但局部差异显著;(3)产业一体化与城市土地利用效率耦合效应的空间正相关性和空间集聚性逐步显化,这种相关性主要表现为空间依赖性和空间异质性。研究结论:根据产业一体化与城市土地利用效率的时空耦合特征,制定差异化的产业发展策略和城市土地利用管控策略,推动产业与土地要素的高效融合。

Coupling Effect of Industrial Integration and Urban Land Use Efficiency: Taking the Urban Agglomeration of the Middle Reaches of the Yangtze River as a Case

The purpose of this paper is to reveal and analyze coupling effect between industrial integration and urban land use efficiency, and to explore the way of coordination from the perspective of spatial effects. The methods used include SVR algorithm, coupling coordination model and spatial correlation analysis. The results show that: 1)industrial integration and urban land use efficiency are mutual promoting and influencing; 2)the coupling degree between industrial integration and urban land use efficiency in the middle reaches of Yangtze River showed an upward trend while the overall spatial imbalance was still expanding in 2003-2015; 3)the coupling effect of industrial integration and urban land use efficiency is gradually explicit in spatial correlation and spatial agglomeration, including spatial dependence and spatial heterogeneity. In conclusion, in order to promote further integration of industry and land resources, different strategies should be formulated according to spatial and temporal coupling characteristics of industrial integration and urban land use efficiency.
