运能、投资与铁路客运市场需求之间的相关模型分析

Relationship on the Demand of Railway Passenger Transportation & Transportation Capacity & Investment

铁路客运在综合客运体系中应发挥重要的作用：但由于铁路客运竞争能力下降，面临严峻挑战。本文采用一种新的研究方法──因果关系检测模型，对运能、投资与铁路客运市场需求之间的相关关系进行了定量分析。得出的结论是：运能与投资不足是导致铁路运输市场份额下降的重要原因。

With a new method of causality detection model, this paper carries out quantitative analysis to the relationship of Railway Passenger Transportation and transportation capacity and investment. The conclusion is that the defect of railway transportation capacity and investment are important causes.
