成渝城市群综合与多维发展测度研究

A Study on the Comprehensive and Multi-Dimensional Development Measure of Chengdu-Chongqing Urban Agglomeration

区域发展测度研究是定量评价区域发展水平及差异重要方法。本文以成渝城市群内四川地级市和重庆区县为研究单元,从经济发展水平、城镇化水平、居民生活水平、交通设施水平、公共福祉6个维度选择15个指标,构建了成渝城市群区域发展综合评价指标体系。采用序排列多边形面积法,对成渝城市群区域发展水平进行多维度综合测度评价,在此基础上,引入协调度模型,对多维系统内部协调性进行定量分析。研究结果表明:成渝城市群综合测度得分偏度系数为4.34,研究区区域发展水平在存在显著差异,在空间格局上呈现出以成都市和重庆主城为核心,川北地区的宜宾市和川南地区的绵阳、德阳、南充为次中心的空间发展格局。在其经济发展水平维度上,测度得分偏度系数为3.92,说明研究区区域经济发展程度具有显著差异;城镇化水平和居民生活水平维度得分偏度系数分别为1.26和1.92,说明研究区内的城镇化水平和居民生活水平差异不明显。就协调度而言,成渝城市群总体水平较低,有濒临失调类型1个、轻度失调类型5个、中度失调类型有14个、重度失调类型10个、极度失调类型6个。成都市和重庆主城分别属于濒临失调和轻度失调,协调度水平有待提高。

Regional development measurement research is an important way to quantitatively evaluate regional development level and difference. This paper uses Sichuan city and Chongqing County in Chengdu Chongqing city group as the research unit, it establishes an evaluation index system of comprehensive development level in Chengdu Chongqing City agglomeration, 15 indicators are selected from 6 dimensions: economic development level, urbanization level, residents’ living standard, transportation facilities level and public welfare. This paper uses the method of ordered polygon area to measure the regional development level of Chengdu Chongqing urban agglomeration. Based on that, the coordination degree model is introduced to quantitatively analyze the internal coordination of multi-dimensional urban system. The research results show that the Chengdu Chongqing city comprehensive evaluation score skewness coefficient is 4.34, there is a significant difference in the regional development level of the study area, the spatial pattern shows in Chengdu city and Chongqing city as the core area of Yibin City, North and South region of Mianyang, Deyang, Nanchong as the center of the spatial development pattern. The level of economic development dimension, measure score skewness coefficient is 3.92, indicating the regional economic development degree of the study area has significant difference;the level of urbanization and residents’ living level scores of skewness coefficient were 1.26 and 1.92, indicating the level of urbanization in the area of study and living conditions were not significantly different. In terms of coordination degree, the overall level of Chengdu Chongqing urban agglomeration is relatively low, which is 1 type of on the verge of disorder, 5 types of mild disorders, 14 types of moderate disorders, 10 types of serious disorders, and 6 types of extreme disorders. The main cities of Chengdu and Chongqing belong to the verge of disorder and mild disorder respectively, and the level of coordination needs to be improved.
