将消费者对乳制品新鲜度的参考效应引入第三方物流（Third Party Logistics，简称 TPL）服务商参与的双渠道乳制品供应链中，考虑到乳制品新鲜度受到制造商加工水平和 TPL 服务商物流服务水平的共同影响，构建分散式、集中式以及引入基于二部定价的成本共担契约下的微分博弈模型，求解并比较三种情形下供应链成员的最优均衡策略。研究表明：一定条件下，基于二部定价的成本共担契约能够使制造商加工水平、TPL 服务商物流服务水平以及供应链整体收益均达到集中式决策下的情形，而且制造商、零售商和 TPL 服务商的收益相较于分散式决策都能得到帕累托改善，供应链能够实现完美协调；线上或线下渠道乳制品的零售价与该渠道所占的市场份额及渠道间的价格替代系数正相关；消费者的参考效应能够激励制造商和 TPL 服务商提高各自的努力水平，使供应链收益增加。
By introducing consumers’ reference effect on dairy products’ freshness in the study of dual channel supply chain in dairy products with the involvement of Third Party Logistics Service Provider (TPLSP) and considering the freshness of dairy products is affected by the processing level of manufacturer and the logistics service level of TPLSP, this paper constructs the differential game models of the centralized, decentralized and a contract of cost -sharing based on two- part tariff. Then the optimal equilibrium strategies of supply chain members in three cases are solved and compared. The results show that: when a certain condition is satisfied, the contract of cost- sharing based on two- part tariff can promote the processing level of manufacturer, the logistics service level of TPLSP and the overall revenue of the supply chain to the state under centralized decision- making, also achieve the perfect coordination of the supply chain by enhancing the revenues of the manufacturer, retailer and TPLSP? the dairy product’s retail price in each channel is positively correlated with the market share of the channel and the price substitution coefficient? consumers’ reference effect can encourage the manufacturer and TPLSP to increase their respective efforts and make increase in supply chain revenue.
