Abstract:

After entering into the World Trade Organization,domestie farm produce market gradually melt into the international market. Thus as one of the most important oil plants,the soybean also receives the press from the international market. Consequenily,it is an important meaning to build the foreeast-warning system of soybean market for domestic soybean industry. In this paper,undergoing to survey the actuality of domestic soybean product,the output,demand and import of the soybean are forecasted using the method of the BPNN and the modified Logistic model.Two irnportant warning alert index of domestic soybean market, that is the dependence degree of the soybean import and the increasing ratio of the price of the soybean,are built the foreeast-warning model.In the end, suggestions corresponding to the early warning conclusion are given.
