摘　　要：Current research into the supply chain coordination problem of product quality focuses mainly on the two-echelon supply chain,and most coordination models neglect the demand relationship between quantity and quality.Even in a direct sale pattern,an agrifood supply chain involves at least four actors,and the contract between different actors may be different.Here,we present a four-echelon agri-food supply chain that consists of one agricultural producer,one processing enterprise,one distributor,and many consumers.We also analyze the quality decision of each actor based on Stackelberg game theory and develop a combined multiple strategy(profit sharing,quality commitment,and risk sharing)for coordinating quality control in the agri-food supply chain.The results show that these strategies affect quality control at the level of the processing enterprise;however,only the profit-sharing strategy and a quality commitment to consumers affect the product quality from agricultural producers.Product quality is not associated with the profit-sharing contract between the processing enterprise and the distributor.Thus,the quality commitment to consumers is the only way for a processing enterprise to control the food market price.Furthermore,enforcing and enhancing this quality commitment to consumers by the processing enterprise will improve the quality of primary agricultural products and food.
