电子商务的发展凸显了平台服务和物流服务的重要性。针对供应链服务平台介入的两个功能型物流服务提供商和单个物流服务集成商构成的物流服务供应链，研究了四种合作模式：集中决策、分散决策、物流服务提供商与集成商合作和两物流服务提供商合作。在价格和物流服务水平共同影响市场需求的前提下，通过构建博弈模型，得到了最优服务水平、服务订购价格、服务销售价格以及整条供应链的总利润；进一步应用数值算例考察了单位信息费和服务水平敏感因子对服务价格、市场需求和利润的影响。研究发现：三种合作模型的供应链总利润总大于分散决策下的总利润，集中决策的销售价格甚至比不合作时的批发价格更低，市场总需求大幅提高并保持最优服务水平不变。研究还表明，供应链服务平台在制定单位信息费时应当慎重斟酌，收取过高费用对于整个市场及参与者极为不利，合理的单位信息费有利于整个市场的健康、长期、稳步地发展。研究结果有助于物流服务供应链企业更好地制定管理决策。

Effective and efficient platform service and logistic operations crucially influence the success of firms in the newly emerged e-commerce. The logistics industry in China is fragmented, which leads to the duplication of logistics information system functions, the irregular and disconnected data, and asymmetric supply and demand information. The current literature related to e-commerce logistics tend to be qualitative, lack of quantitative analysis about how firms could effectively cooperate with partners. This study aims to investigate a logistics service supply chain system which involves in two functional logistics service providers, a single logistics service integrator and a supply chain service platform. There are four kinds of cooperative models are developed: the centrally cooperative system, the decentralized system, the L-F cooperative system and the F-F cooperative system. It is assumed that consumer demands are determined by sales price of service and logistics device level. Then, the optimal service level, the optimal wholesale price of service, the optimal sales price of service, and total supply chain profits are given by game-theoretic model. Furthermore, numerical examples illustrate the impact of unit information fee and sensitive factors of service level on the service price, market demand and the profits. It is found that the total supply chain profits of three cooperative models are always more than that of the decentralized system. The sale price of centralized system is even lower than the wholesale price of the decentralized system, the total market demand is significantlly increase and the optimal service level remains the same. Research results also show that when the supply chain service platform makes rules of the unit information fee, high charge is undesirable for the whole market and the players. Therefore, reasonable scope of charge can help the whole market have a long-term, steady and healthy development. The results of this study can help firms determine their practical strategies.
