Tao WANG, Shan LIN

Abstract


According to the characters of few economic forecasting data and complicated action mechanism, this paper makes use of the time sequence prediction theory of improved grey GM (1, 1) model to predict China’s economic contraction years, overheating years and economic cycle, and analyses the important function of grey prediction model in the economic forecasts.
