文章在探讨线性函数弹性规律的基础上,以1990—2014年各种交通运输方式货运量国内生产总值为样本数据,以国内生产总值为主驱动因子探讨我国各种运输方式货运量的变化规律,采用回归拟合分析方法,旨在寻找货输量对经济发展的函数关系,通过分析货运量对经济发展水平的反应的灵敏程度,从而对未来货运量及弹性进行预测,为未来交通运输方面的决策作出贡献。
Based on the discussion of the elastic law of linear functions, taking the GDP of all modes of transport in 1990-2014 as the sample data and GDP as the main driving factor, this paper discusses the changes of the freight volumes of various modes of transport in China. The law, using regression fit analysis method, aims to find the freight volume on the economic development of the functional relationship, by analyzing the sensitivity of freight volume to the level of economic development, so as to predict future freight volume and flexibility for the future of transport Aspects of the decision to contribute.
