摘要
利用线性回归模型研究我国近二十年来人均消费量与主要影响因素之间的数量关系,通过对模型的不断改进,最终获得人均消费计量模型的线性回归,此结论能很好地解释近二十年来人均消费水平发生的变化。
By using the linear regression model; the quantitative relation between the national per-capita consumption and its major modifying factors was studied for recent twenty years. The ultimate linear regression was obtained through constant improvements of the model, And the results can explain the change of the national per capita consumption in recent twenty years very well.
