摘　　要：分析客车销量的影响因素,将客车销量作为因变量,影响因素作为自变量,基于EViews软件建立多元回归数学模型,并通过逐步回归法克服模型的多重共线性,对回归方程进行相关性检验和实例验证。研究表明:客车销量与轨道交通客运量正相关,与国内生产总值负相关。This paper analyzes the influencing factors of bus sales,in which bus sales are taken as dependent variables and influencing factors as independent variables.A multi-regression mathematical model is established based on EViews software.Through the gradual regression method to overcome the multi-collinearity of the model,the regression equation is verified for the correlation and examples.The study shows that bus sales are positively correlated with the rail transit passenger volume and negatively related to GDP.

关 键 词：客车销量 EVIEWS 多元回归模型 国内生产总值 轨道交通客运量
