重庆市城镇化与交通协调互动发展研究

Research on coordinated and interactive development of urbanization and traffic in Chongqing

为厘清重庆市城镇化与交通的协调互动关系,通过构建城镇化与交通评价指标体系,运用熵值法、耦合协调度模型和格兰杰因果检验模型对重庆市2003年—2018年城镇化与交通协调发展水平及互动关系进行了实证研究.结果发现,重庆市城镇化与交通的耦合度和耦合协调度均上升较快,城镇化与交通的相互依赖程度在逐年提高,耦合协调度共经历了四个阶段.格兰杰因果检验发现,短期内,城镇化发展是引起交通发展的重要原因,但交通对城镇化的促进作用不显著.从长期来看,交通发展对于城镇化的扩展和蔓延具有十分积极的影响.

In order to clarify the coordinated interaction between urbanization and transportation in Chongqing,to analyze an empirical study on the urbanization and its coordinated development level and interactive relationship in 2003-2018 was analyzed by using the entropy method,coupled coordination model and Granger causality test model.The results show that the coupling degree and coupling coordination degree of urbanization and transportation in Chongqing have both increased rapidly,and the interdependence between urbanization and transportation has increased year by year.The coupling coordination degree has gone through four stages.Granger causality test found that urbanization development is an important cause of transportation development in the short term,but the role of transportation in promoting urbanization is not significant.In the long term,transportation development has a very positive impact on the expansion and spread of urbanization.
