Abstract: | By analyzing the results of existing research of pork prices forecast in the domestic and foreign country, and according to China's national conditions, this paper established a price impact index, proposed dynamic combination forecast techniques, and created a dynamic combination of predictive models. Through experiment, the paper compared the three models, which were BP neural network method for predicting, minimum prediction error squares as the objective function of the prediction model and dynamic combination model of two methods. The results show that dynamic combination forecast method has the advantage of high accuracy. |
