Abstract: This paper assumes that the manufacturer’s wholesale price is an endogenous variable and the market demand of the retailer is affected by the service level of TPL provider. We studies the decision-making behavior and operational efficiency of a production-transportation-marketing system under integrative alliance, decentralized decision, production and transportation alliance, transportation and marketing alliance mode respectively. The mathematical models are developed under these four modes and then the existence and uniqueness of the optimal solutions or game equilibrium solutions are proved. Through the pairwise comparison, we find that the system’s profits under the other three modes are lower than that in the integrative alliance. Moreover, the value size of the optimal ordering quantity, logistics service level and the ratio between them under other three modes depends on some specific conditions. Therefore, the supply chain internal alliance may not be able to improve the system operational efficiency. We further give a numerical example and then do the sensitivity analysis on the retail price and variable logistics service cost. Finally, we find that the system operation efficiency under the transportation and marketing alliance mode is highest among these three decision modes in most cases.
