Research On The Interest Decision-Making Model Of Logistics Service Supply Chain Based On Supply Chain Contract

With the acceleration of economic integration, enterprises are facing daedal product requirement and the increasingly fierce market competition."Supply Chain Management Theory" can solve the above problems and has received much attention from academia and business community.Twenty-first Century is the century of service economy,"Supply Chain Management" has been widely applied to service supply chain because of services sector in the economy and rapid development of service industry.At present, research and application of logistics services supply chain mostly pay much attention to the design of complex contract model in order to achieve biggest system performance or maximum profit, but a big gap exists between design and reality conditions. For example, whether contract design is reasonable and flexible or not, whether logistics capability requirement factors (logistics price and promotion efforts) are adopted and considered, whether mutual interest decision is stable and feasible, etc. Therefore it is necessary to research decision-making of each trader under the above factors.From the perspective of interest decision of each trader, based on contract theory and optimality theory, using quantitative analysis and game theory, this paper studies the interest decision of each trader in different conditions. Firstly, this study reviews relevant references of service supply chain and logistics service supply chain; studies logistics service supply chain’s connotation and characteristic, especially buy-back contract and game theory; and discusses research fronts and deficiency in each field. Secondly, with perfect information, this paper builds capability coordination mechanism which logistics plays leading role based on buy-back contract and quantity discount; explores best interest decision-making in the condition of Stackelberg Model; and analyzes the influence of discount to each decision. The interests decision-making model of logistics service supply chain is created with influence demand of efforts; the best interest decision are explored in the condition of centralized decision, non-cooperative decision, and cooperative decision; a systematic profit distribution method is proposed on the basis of both operating cost; and proves the effectiveness of three models through examples. Finally, considering rationality, stability and feasibility of interest decision in upstream and downstream enterprise, making interest decision that be acceptable, stable and feasible to both by Perfect Bayesian Equilibrium and Backward Introduction, this study researches the interest decision stability of each trader with examples in a asymmetric situation.
