| Abstract: | Based on the discrete grey forecasting model,the metabolism discrete grey forecasting model was proposed in the paper.In other words,focusing on the initial date series,the different discrete grey forecasting models were established one by one accordingly by applying the pattern of metabolism.And then,the tourism income of Jiangxi province was predicted in medium and long-term by applying the metabolism discrete grey forecasting model.Last,the precision of the model was examined.The results show that the precision of the model is comparatively higher and the model can be used as a tool for the medium and long-term predictions. |
