Abstract: Due to lack of comprehensive understanding on green service supply chain,a two-level product service supply chain consisted of one cell phone manufacturer and one telecom service provider was constructed.It considered sales of tangible cell phone products and intangible telecom service besides green levels of products impacting both product and service sales.In centralized and decentralized settings,green decisions were solved and analyzed.After confirmed that cost sharing contracts had failed to coordinate the product service supply chain,a two-part tariff contract was put forward to implement a green coordination of the supply chain.The green level of cell phone products and the profits of supply chain were both improved evidently after implementing the coordination contract,and the effectiveness of the contract was verified with numerical case.
