摘要

In this paper, on the basis of an analysis of the current status of the railway freight transportation industry in China and by selecting the time-series data of the years from 1990 to 2012, we had a co-integration test and Granger causality check of the relationship between the railway freight transportation industry and the growth of the national economy and reached some pertinent conclusions.%在分析我国铁路货运现状的基础上，选取1990-2012年的时间序列数据，对于铁路货运与国民经济增长的关系进行了协整检验和格兰杰因果关系检验，得出我国铁路货运与经济增长之间存在协整关系，但不存在双向的因果关系。
