摘要
成渝经济圈在国家发展全局战略中占据独特而重要的地位.基于熵值法和耦合协调度模型对成渝经济圈44个地级县(区、市)人口、经济、空间城市化水平及其耦合协调情况进行分析.结果发现:(1)成渝经济圈经济城市化水平空间分异最为显著,反映出内部各城市之间经济发展程度差异较大.(2)城市化进程中,成渝经济圈是以空间城市化为主导的经济城市化和人口城市化.(3)成渝经济圈内部区域差异明显.成都市和重庆市主城区的城市化水平较高,城市化得分由内向外递减,形成梯级分化.(4)成渝经济圈人口-经济-空间两两及三者之间城市化耦合水平较低,总体处于拮抗阶段.(5)按照协调度水平分别进行排序,可以划分为4种类型.成渝经济圈内人口-经济-空间城市化耦合协调水平较低,加之政府在政策上的大力支持,为成渝经济圈城市协同发展提供了巨大的发展潜力.
Abstract
The Chengdu-Chongqing Economic Circle occupies a unique and important position in the overall strategy of national development.Based on the entropy method and the coupling coordination degree model,the population,economy,spatial urbanization level and coupling coordination of 44 prefecture-level counties(districts and cities)in Chengdu-Chongqing economic circle are analyzed.The results show that:(1)The spatial differentiation of economic urbanization level in Chengdu-Chongqing economic circle is the most significant,reflecting the great difference in economic development among cities.(2)In the process of urbanization,the Chengdu-Chongqing economic circle is dominated by spatial urbanization,which in turn domi-nates the economic urbanization and population urbanization.(3)There are obvious regional differences within the Chengdu-Chongqing economic circle.The urbanization level of Chengdu and the city proper of Chongqing is relatively high,and the ur-banization score decreases from inside to outside,forming a cascade differentiation.(4)The urbanization coupling level among population,economy and space or between one another in Chengdu-Chongqing economic circle is low,staying generally in the antagonistic stage.(5)Based on the level of coordination,it can be divided into four types.The coupling and coordination level of population-economy-space urbanization in Chengdu-Chongqing Economic Circle is low,and the strong support of the govern-ment in policy provides great development potential for the coordinated development of cities in Chengdu-Chongqing Economic Circle.
