摘要： Food prices kept rising up and had affected residents' life quality during recent years. Food prices trends and the determinants behind attract wide attentions. China Economy-wide Multi-market Model(CEMM) is constructed to simulate the price effects of supply and demand in this paper. Three scenarios are designed to access the price effects of supply, demand and their combine effects, respectively. The results shows that the production costs rising and constrained supply are the main important factors which lead to food prices rising. The boosting demand for maize as industrial use and livestock products also put a great pressure on food price rising. Ensuring the supply of main grains and meats is one of important tasks for the government to stabilize the price. So, the fourth scenario is designed to evaluate the price effects of the increase in production. The model simulation results evident that the improvement of productivity is an effective measure to slow rising food price.
