质量—效率视角下城镇化发展的耦合协调性研究

城市群作为我国经济发展格局中最活跃的单元，其质量与效率的高度耦合协调是我国经济社会发展的重要保障，也是助推城镇化高质量发展的重要动力。研究以长三角城市群中心区27个城市为例，运用AHP与熵值法、DEA-BCC模型，分别从城镇化质量与城镇化效率选取指标，并借助耦合协调模型，以探究二者耦合协调度。研究表明：①长三角城市群城镇化质量总体呈现上升态势，但存在一定的地区差异，表现为“东高西低”的格局特征；城镇化综合效率发展稳定，综合效率达到“有效”的城市呈现由东向西的扩张趋势；②2010~2014年，城镇化质量与效率的耦合度和协调度发展态势基本一致，均呈现上升趋势；2014~2018年，耦合度呈现弱下降趋势，协调度保持上升态势。研究期末，城镇化质量和城镇化效率的耦合度、协调度在空间上大体呈现“东部高、西部低”的特征。研究希冀为城镇化高质量发展提供数据支持和理论支撑。

Research on the Coupling Coordination of Urbanization From the Perspective of Quality-efficiency

The urban agglomeration is the most active unit in China''s economic development, and its high coupling coordination of quality and efficiency contributes to China''s socio-eco development and the high-quality urbanization. Taking 27 cities in the central area of Yangtze River Delta urban agglomeration as examples, this paper uses AHP, EWM and DEA-BCC model to select indicators from urbanization quality and urbanization efficiency respectively, and explore their coupling coordination with the coupling coordination model. The results show that: (i) the urbanization quality of Yangtze River Delta urban agglomeration shows a rising trend, but there are some regional differences, namely the pattern of high in the east and low in the west; the comprehensive efficiency of urbanization is stable, and cities with effective comprehensive efficiency is increasing from east to west; (ii) from 2010 to 2014, the coupling degree and coordination degree of urbanization quality and efficiency are basically the same, both showing an upward trend; from 2014 to 2018, the coupling degree shows a weak downward trend, and the coordination degree maintains an upward trend. At the end of the study period, the coupling degree and coordination degree of urbanization quality and urbanization efficiency are spatially high in the east and low in the west. This paper aims to provide data and theoretical support for high-quality urbanization.
