基于DEA-C2R模型的区域交通运输协调效率分析

摘要

交通运输是社会经济发展的基础。通过提高不同交通运输方式之间的协调效率可以实现同等交通规模下交通综合运输能力的提高。选取不同交通方式的合理指标和数据，采用数据包络分析的方法对不同交通运输方式之间的运行效率进行分析，通过效率变化情况说明区域交通运输主要构成方式之间的协调配合水平。实证研究结果表明，通过不同交通方式之间的协调效率提高，可以减少交通对土地、能源和环境影响，实现区域交通运输能力的提高。%Transport is the development foundation of social and economic .By improving the coordination efficiency between different transport modes,can realize the ability increase of comprehensive traffic under the same traffic -scale .Select reasonable indicators and datas on different transport modes, explain coordination levels between the main components way of regional transport by the efficiency changes .The empirical results show that, to improve coordination efficiency between the different transport modes , can reduce the impact of traffic on land , energy and the envi-ronment,to improve the regional transportation capacity.
