摘　　要：铁路货运作为大宗货物的重要运输方式,深刻影响着区域经济发展。为了分析影响广西铁路货运量的主要因素,选取广西铁路货运量作为因变量,对近年来的可能影响广西铁路货运量的经济数据建立相关的模型进行分析。首先对各潜在影响因素进行双变量相关性检验完成初步筛查,排除一部分无关因素。在此基础上通过因子分析找出公因子,并通过聚类分析进一步验证因子相关性。最后通过多元线性回归分析建立线性回归方程,以定量形式解释广西铁路货运量与各影响因素的数量关系。得出了工业因子对广西铁路货运量影响较大,农业因子次之的结论,并对该结论结合实际情况进行了分析解释。As an important mode of transportation of bulk goods,railway freight has a profound impact on regional economic development.In order to analyze the main factors that affect Guangxi's railway freight volume,Guangxi's railway freight volume is selected as the dependent variable,and relevant models are established to analyze the economic data that may affect Guangxi's railway freight volume in recent years.First,a bivariate correlation test was conducted on each potential influencing factor to complete the preliminary screening and exclude some irrelevant factors.On this basis,common factors are found through factor analysis,and the factor correlation is further verified through cluster analysis.Finally,a linear regression equation was established through multiple linear regression analysis to quantitatively explain the quantitative relationship between Guangxi railway freight volume and various influencing factors.The conclusion is drawn that industrial factors have a greater impact on Guangxi's railway freight volume,followed by agricultural factors,and this conclusion is analyzed and explained based on the actual situation.
