Abstract: According to the mechanism of the grey prediction model and the assignment process of the background value,this article combined with the Lagrange mean value theorem to prove that the assignment of the background value is not reasonable in mathematics.Aiming at the unreasonable place,this article puts forward an improved method model.Then this article carried on the empirical analysis with the Chongqing rural electricity consumption,and verifies the model improvement.
