济南都市圈综合交通运输与区域经济耦合测度分析

Measure and analysis of the coupling between comprehensive transportation and regional economy in Jinan metropolitan area

为分析交通运输与区域经济之间的耦合关系,从需求规模和供给规模2个层面,探究涵盖公路、铁路和航空3种运输方式的综合交通运输系统发展指标,结合经济系统的社会规模和经济规模指标,建立综合交通运输与区域经济耦合发展评价指标体系;基于协调发展指数评价模型,引入交通贡献率参数,得到改进耦合协调测度模型,通过计算耦合协调发展指数,揭示交通运输与区域经济之间的关系及相互作用机理。以济南都市圈为例,根据2014—2020年各城市统计年鉴中交通运输系统的供给规模和需求规模数据、区域经济系统的经济规模与社会规模数据,测度并分析济南都市圈综合交通运输与区域经济系统之间的协调发展水平,提出良性的耦合发展对策。

For the analysis of the coupling relationship between transportation and regional economy,from the two aspects of demand and supply scales,the indicators of comprehensive transportation system development modes including road,railway and air are explored.The comprehensive transportation and regional economy development evaluation index system of the coupling is set up according to the indexes of the social and economic scale for the economic system.Based on the evaluation model of coupling development index,the improved coupling coordination measure model is obtained by introducing the traffic contribution rate parameter.The relationship and interaction mechanism between transportation and regional economy is revealed by calculating the coupling coordinated development index.Taken the Jinan metropolitan area as the show case,after the coordination development level of the comprehensive transportation and regional economy in the Jinan metropolitan area is measured and analyzed,then the benign coupling development countermeasures are put forward by using the model,according to the supply and demand scale data of the transportation system and the economic and social scale data of the regional economic system in the 2014-2020 statistical yearbook of cities in China.
