| Abstract: | This paper forecasted the grain gross output of Inner Mongolia by improved back propagation algorithm with high forecast precision.The forecasting result showed that the grain gross output of Inner Mongolia has a stable increasing trend from 14.755 7 million tons in 2002 to 21.034 3 million tons in 2011.Finally,this paper put forward the methods to achieve the forecasting of outputs. |
