长江经济带土地出让与城镇化质量耦合协调研究

Study on Coupling and Coordination of Land Transfer and Urbanization Quality in the Yangtze River Economic Belt

土地出让与城镇化质量作为城镇化的主要依托和核心追求,二者的关系影响到城市的可持续发展。以长江经济带为例,构建土地出让与城镇化质量综合评价指标体系,利用熵值法和耦合协调模型对二者耦合协调的时空差异做出实证研究,并利用ArcGIS将其空间显化。实证结果表明:研究期内长江经济带土地出让与城镇化质量的协调度呈现先增后减再增趋势;二者的协调度自西向东逐步增加,耦合度无明显分布规律,总体呈高水平耦合状态;土地出让与城镇化质量的协调度在城市群间的差异显著,但城市群内部的差异逐步减小。从土地出让与城镇化质量的耦合协调发展的视角,为实现城市健康可持续的发展提出政策建议。

As the main support and core pursuit of urbanization,the relationship between land transfer and urbanization quality affects the sustainable development of cities.Taking the Yangtze River Economic Belt as an example,a comprehensive evaluation index system of land transfer and urbanization quality is constructed,and an empirical study on the spatial-temporal differences of the coupling coordination between the two by using the entropy method and the coupling coordination model is analyzed,then the spatial manifestation of the coupling and coordination is made by using ArcGIS.The results show that:the coordination degree between land transfer and urbanization quality shows a trend of increasing first,then decreasing and then increasing.The coordination degree of the Yangtze River Economic Belt gradually increases from west to east,the coupling degree has no obvious distribution law,and the overall is in a high level coupling state.The difference between the degree of land transfer and the quality of urbanization has always existed among urban agglomerations,however the differences within urban agglomerations are gradually decreasing.From the perspective of coupling and coordinated development of land transfer and urbanization quality,policy recommendations for achieving healthy and sustainable urban development are put forward.
