| Abstract: | Profit Portion estimation for the mechanization in agricultural industry is useful for government strategic decision-making.By applying the prediction methods of the gray system theory,the prediction models were built and their prediction was made,including gross output value,mechnization input,material consumption,labor force participation and land area input.Then the mechanization profit portion in agricultural products industry was estimated. |
