An E-supply chain composed of a manufacturer and an e-commerce platform with self-established logistics was estab-lished.The manufacturer not only sells their products through the e-commerce platform agent,but also wholesales products to the e-commerce platform for distribution.From the perspective of the e-commerce platform′fairness concern about the dynamic change of information,this paper analyzes the impact of fairness concern about the dynamic change of information on the pricing decisions,efficiency and fairness degree of the E-supply chain under the mixed-sale mode.The research shows that when the e-commerce plat-form transmits the true fairness concern information or false fairness concern information to the manufacturer,it is beneficial to ob-tain more profit for itself,but the intensity value of fairness concern should be within a reasonable range,otherwise,it will reduce the subjective fairness degree and objective fairness degree of the supply chain.When the e-commerce platform does not transmit the true fairness concern information to the manufacturer,the profit of each member of the supply chain and the total profit of the supply chain are the lowest,and the efficiency of the supply chain will decrease with the increase of fairness concern.When the proportion of revenue sharing obtained by the manufacturer is within a certain range,it is beneficial to improve the subjective fairness degree and objective fairness degree of the supply chain.However,when it exceeds a certain range,it will reduce the fairness degree of the supply chain.
