摘要
根据1996～2009年中国统计年鉴的数据,利用逐步线性回归建立了我国民用汽车保有量的预测模型,检验结果表明模型回归效果良好。通过对模型进行的分析可知,我国民用汽车保有量的主要影响因素是交通运输业的发展。
According to the data from 1996 to 1997 of China Statistical Book, this paper established prediction model for civil vehicle quantity of China by using stepwise linear regression, and the test results show that the effect of the regression model is very good. And based on the analysis of the model, the analytical results show that the main factor affects China＇s civil vehicle quantity is the development of transportation.
