According to the modeling mechanism of GM (1, 1) model, based on the analysis of the disadvantages of the original grey model GM (1, 1) modeling parameter. The Novelly optimized initial value of GM (1, 1) was proved in theorem 2, and the novel GM (1, 1) was constructed and compared with the original GM (1, 1) and its optimized models in modeling precision. The research findings indicate: the novelly optimized GM (1, 1) is not only suitable for the modeling for the low growth index sequence but also suitable for the modeling for the high growth index sequence. When the development coefficient is bigger than 2, the modeling precision (simulation precision and forecast precision) of the novel GM (1, 1) model is still very high.
