摘要
主要介绍了GM(1,1)模型的建模机理,借助该模型对成都市生产总值进行预测。通过对预测结果进行残差分析,说明了该方法的合理性。成都市生产总值的预测值可以较准确地反映该地区未来的经济状况。
This paper introduces the mechanism of the GM(1,1)-based model which is used to forecast the GDP of Chengdu.The residual analysis of the predicted results shows that such a method is reasonable.The predicted results can quite exactly reflect the future economic development of Chengdu.
