Research on soybean security of China based on system dynamics

Based on considerations of soybean production, imports and exports trade, processing and consumption, we study the soybean industry of China with the method of system dynamics. Firstly, we build the SD model of soybean industry. Secondly, we optimize soybean security policy simulation dynamic model and simulate the model based on our country specific situation. At last, on the basis of the simulation results, we analyze current domestic soybean industry security situation and provide a method to make suggestions for soybean security policy.
