Research on the Grey Econometric Model with Lags Information

This paper aim at developing the grey econometric model with lags information. Considering the breakpoint of the traditional econometrics model, the study gives the primary steps and constraint condition of grey econometric model with lags information. Furthermore this paper makes empirical analysis using data from a segment market, and tests the average relative error of the model. The result reveals that the grey econometric model with lags information improves the accuracy of traditional grey model.
