Abstract: Aiming at the three-level supply chain, this passage focus on how to distribute the profit of supply chain under a centralized strategy fairly and reasonably, as well as build up an effective strategy model of supply chain profit allocation based on cooperative game theory and figure out the Shapely value of the benefit distribution. Besides that, the Shapely value could be modified according to the relevant factors of the benefit allocation of the joint enterprises so that it can work out the problem of distributing profit effectively and reasonably in the supply chain. In addition, it is obvious to optimize the interest of the whole supply chain as well as maximize the partial interest of the joint enterprise, thus, promoting and maintaining the operation of supply chain effectively and steadily.
