The quality and safety of agricultural products is related to the national economy and the people's livelihood.More and more scholars have studied from the perspective of agricultural supply chain to propose effective strategies and suggestions for control and improve the quality of agricultural products.On the one hand,the existing research mainly considers the impact of unilateral efforts of a member in the agricultural supply chain on the quality control of agricultural products,while ignoring the joint efforts of all parties in the supply chain,the improvement of agricultural products quality is limited;On the other hand,the influence of social preferences on the efficiency and fairness degree of supply chain has been neglected.An important reasons for the quality problem of agricultural product is that one or some members of the supply chain think that the distribution of profits in the agricultural supply chain is unfair and make decisions that impair quality,thereby reducing the quality of agricultural products and the efficiency of supply chain.Therefore,it is necessary to introduce social preferences to study the bilateral quality control of agricultural supply chain,so as to further improve the quality of agricultural products.The main work and important conclusions are as follows:Firstly,the bilateral quality control strategies of the agricultural product manufacturer and the supermarket under the complete rationality of both sides are studied.By comparing and analyzing the equilibrium solutions of centralized and decentralized decision-making,the results show that:(1)The quality effort level of agricultural products manufacturer is higher in centralized decision-making than in decentralized decision-making;The inspection effort level of supermarket remains unchanged in the supply chain centralized and decentralized decision-making.(2)When decentralized decision-making,the maximum expected profit of agricultural products manufacturer is always lower than the maximum expected profit of supermarket.(3)The maximum expected profit of supply chain is higher in centralized decision-making than in decentralized decision-making.Secondly,the fairness preference of agricultural products manufacturer is introduced into the agricultural supply chain to study the impact of agricultural products manufacturer's fairness preference on the bilateral quality control strategy,the efficiency and fairness degree of supply chain.Through the comparison and analysis with the completely rational supply chain,the results show that:(1)The quality effort level of agricultural products manufacturer,the inspection effort level of supermarket and the maximum expected profit of supply chain are not related to the agricultural products manufacturer's fairness preference;The purchase price of supermarket,the maximum expected profit and utility of agricultural products manufacturer are positively related to the agricultural products manufacturer's fairness preference;The maximum expected profit and utility of supermarket are negatively related to the agricultural products manufacturer's fairness preference;The maximum expected utility of supply chain is first negatively correlated and then positively correlated with the agricultural products manufacturer's fairness preference.(2)When the fairness preference of agricultural products manufacturer is strong,the subjective efficiency of supply chain can be improved,the subjective efficiency of supply chain is higher than the objective efficiency,and the efficiency of the supply chain can be optimized by the subjective evaluation;The objective efficiency of supply chain is not affected by the agricultural products manufacturer's fairness preference.(3)When the fairness preference of agricultural products manufacturer is weak,the objective and subjective fairness degree of supply chain can be improved,the objective fairness degree of supply chain is higher than the subjective fairness degree,and both objective and subjective evaluation of supply chain can optimize the fairness degree of supply chain.Therefore,when the fairness preference of agricultural products manufacturer is weak,the objective evaluation of supply chain can not only guarantee the efficiency of supply chain unchanged,but also optimize the fairness degree of supply chain,so as to achieve the coordination of supply chain with efficiency and fairness degree.Thirdly,the altruistic preference of supermarket is introduced into the agricultural supply chain to study the influence of supermarket's altruistic preference on the bilateral quality control strategy,the efficiency and fairness degree of supply chain.Through the comparative analysis with the completely rational supply chain,the results show that:(1)The quality effort level of agricultural products manufacturer,the purchase price of supermarket,the maximum expected profit and utility of agricultural products manufacturer,and the maximum expected profit of supply chain are positively related to the supermarket's altruistic preference;The inspection effort level of supermarket is not related to the supermarket's altruistic preference;The maximum expected profit of supermarket is negatively correlated with the supermarket's altruistic preference;The maximum expected utility of supermarket and supply chain are first negatively correlated and then positively correlated with the supermarket's altruistic preference.(2)When the altruistic preference of supermarket is weak,the objective efficiency of supply chain can be improved,the objective efficiency of supply chain is higher than the subjective efficiency,and the efficiency of supply chain can be optimized by the objectively evaluation;When the altruistic preference of supermarket is strong,the subjective efficiency of the supply chain can be improved,the subjective efficiency of the supply chain is higher than the objective efficiency,and the efficiency of supply chain can be optimized by the subjective evaluation;(3)When the altruistic preference of supermarket is weak,the objective and subjective fairness degree of supply chain can be improved,the subjective fairness degree of supply chain is higher than the objective fairness degree of supply chain,and the fairness degree of supply chain can be optimized no matter from objective evaluation or from subjective evaluation.Therefore,when the altruistic preference of supermarket is weak,the objective evaluation of supply chain can not only improve the efficiency of supply chain,but also optimize the fairness degree of supply chain,so as to achieve the coordination of supply chain with both efficiency and fairness degree.Finally,according to the conclusions about the impact of fairness preference and altruistic preference on the bilateral control strategy of the supply chain,the efficiency of the supply chain,and the fairness degree of the supply chain,the corresponding management suggestions are obtained: For the agricultural products manufacturer,transfer the intensity of fairness preference actively,disclose its own production and processing costs actively,carry out large-scale agricultural production and processing,strive to improve the quality of agricultural products,implement agricultural product brand strategy and improve corporate system and norms;For the supermarket,focus on the fairness of profit distribution,invest in agricultural technology research,establish an overall awareness of the supply chain,emphasis on self-altruistic preference intensity actively,improve agricultural product quality inspection system and implement standardized agricultural product recall procedures.
