摘要
根据某地区相关的统计数据,运用多元回归分析法,对该地区影响私人汽车发展的主要因素进行分析,对其保有量的发展趋势做出科学判断。然后,运用灰色系统理论,建立了该地区私人汽车保有量的预测模型GM(1,1)模型及其修正模型,找出其中的相关性和函数关系,从而对该地区私人汽车保有量进行定量的分析和预测。
According to the relevant statistical data of a region, this paper makes an analysis of the major factors that impact on the development of private cars number and its trends in the region using the methods of linear regression. And then, with the gray system theory, the forecast model of private cars number based on GM （1,1） and its correction model are established. We can make the quantitative analysis and forecast the private cars number with the pertinence and function relation in the model.
