Considering fairness concerns of the service integrator, a game model of the service provider and the service integrator is established. The analysis demonstrates that the wholesale price contract can’t realize the service supply chain coordination. Therefore, a combined contract of “cost sharing and revenue sharing” is presented to coordinate the service supply chain, and its effectiveness is discussed. The study results show that: the contract of cost sharing and revenue sharing can’t achieve the coordination of service supply chain, the combined contract can’t only coordinate the service supply chain, and also its coordination has flexibility. But with fairness concerns of the service integrator increasing, the negotiation space of the service provider and the service integrator becomes small, and the coordination flexibility will gradually weaken and more unfavorable for the service provider.
