长江经济带主要运输方式比较优势及其竞争格局分析

Analysis of Comparative Advantage and Competitive Situation of Major Transport Modes in Yangtze River Economic Belt

运用标准显示性比较优势(NRCA)计算长江经济带主要运输方式的线路长度、客运量和货运量的比较优势。同时,引入分享偏移模型测算长江经济带主要运输方式货物运输的相对竞争优势。从"态"、"势"的角度综合分析长江经济带上游、中游和下游地区未来主要运输方式的发展方向,分析结果与实际建设情况相符,说明该套方法体系在交通运输领域的研究具有可行性和指导意义。

In this paper, using the normative revealed comparative advantage model, we calculated the comparative advantage of the major transport modes in the Yangtze River Economic Belt in terms of route length, passenger transport volume and freight transport volume, then introduced the shared deviation model to measure the relative competitive advantage of the modes in freight transportation, and at the end, from the angle of status and trend, analyzed the future direction of the freight transportation means along the Yangtze River Economic Belt.
