基于熵值法的成渝城市群城市化水平综合评测

Comprehensive Evaluation of Urbanization Level of Chengdu-Chongqing Urban Agglomeration based on Entropy Method

成渝城市群作为具有全国影响力的区域经济中心,其城市发展历程对中国城市化建设具有重要指引作用。基于区域城市化水平综合评测方法构建城市化综合测评体系,结合熵值法综合评估成渝城市群主要节点城市2000-2020年的发展状况,结果表明:(1)成渝城市群城市化的发展主要以经济城市化为主,空间城市化和社会城市化发展次之,人口城市化发展占比最低。(2)节点城市指标层分析发现,重庆市和成都市的发展质量远超其余城市,重庆市城市化演变表现为经济、人口、空间、社会共同发展,而成都市在人口城市化发展上稍显缓慢。(3)德阳、绵阳等大型城市在城市化发展上均有所提升,在社会城市化较强的基础上加速发展经济,空间和人口的城市化发展力度则有所减缓。

As a regional economic center with national influence,Chengdu-Chongqing urban agglomeration plays an important guiding role in China’s urbanization.Based on the comprehensive evaluation method of regional urbanization level,this paper constructs a comprehensive evaluation system of urbanization,and combines the entropy method to comprehensively evaluate the development status of the main node cities of Chengdu-Chongqing urban agglomeration from 2000 to 2020.The results show that:(1)The development of urbanization in Chengdu-Chongqing urban agglomeration is mainly based on economic urbanization,followed by spatial urbanization and social urbanization,and the proportion of population urbanization is the lowest.(2)The analysis of the node city index layer shows that the development quality of Chongqing and Chengdu is much higher than that of the other cities.The urbanization evolution of Chongqing is characterized by the common development of economy,population,space and society,while the development of population urbanization in Chengdu is slightly slow.(3)Large cities such as Deyang and Mianyang have improved their urbanization development,accelerated their economic development on the basis of strong social urbanization,and slowed down the urbanization development of space and population.
