成渝城市群经济与交通运输通道协同演化表征方法

评估经济与交通运输通道的协同演化是考量城市群整体发展的重要手段，然而，目前却没有专门的研究来解释协同度分析中具体指标的影响机制.因此，本文采用性能化的评估方案，从微观、宏观、中观3个层面建立了成渝城市群经济与交通运输通道协同演化表征方法. 通过数据拟合、秩相关分析和Pawlak粗糙集约简，建立了完整的评估方法体系，科学分析了协同演化趋势，确定了不协同指标.研究结果表明：成渝城市群经济与交通运输通道具有较强的协同关系；不协同指标为成都经济的结构和效益性指标，重庆经济的效益型指标及交通运输通道中的结构性指标.本文调查结果有助于评估城市群的协同水平，为城市群的进一步发展提供参考.

Co-evolutionary Characterization of Economy and Transportation Corridor for Chengdu-Chongqing City Group

Assessing the co-evolutionary characterization of economy and transportion is an important measure to consider the overall development of a city group. However, there is no study specifically available to explain the impact of specific indexes involved in the co-evolutionary analysis. Thus, based on affordances evaluation, the paper establishes the co-evolutionary characterization methods of economy and transportation corridor for Chengdu-Chongqing city group from the analyses of microscopic, macroscopic and mesoscopic. By means of the data fitting, rank correlation analysis, and Pawlak rough set reduction, a complete evaluation system is established and co-evaluation relationship is determined. Furtherly, non co-evolutionary indexes are identified. Results show that: there is a strong co-evolutionary relationship between economy and transportation corridor for ChengduChongqing city group; non co-evolutionary indexes are the economy structure and efficiency indexes in Chengdu, the economy efficiency index of Chongqing, and the structure index of transportation corridor. The findings will help to evaluate the co-evolutionary of city group and provide the suggestions for the further development.
