Research on coordination mechanism in three-level green supply chain under non-cooperative game

In view of the three-level green supply chain system in which market demand correlates with product green degree, game theory is applied to study four models, namely cooperative decision-making, three-level leader–follower game, Stackelberg game I and Stackelberg game II. Theoretical analysis shows that the profits of both the supply chain system and participating members reach the optimal level under cooperative decision-making, while the decision results of participating members as well as the channel profit are far from satisfactory under the non-cooperative game. By building a revenue sharing mechanism, Shapley value method coordination mechanism and asymmetric Nash negotiation mechanism, supply chain members are motivated to respond positively to the cooperation in producing and marketing green products, the optimal income distribution coefficient of participating members is given, and the income of each member is increased substantially as is compared with that under the non-cooperative game. Also, by determining the cooperative parameter, green supply chain managers may effectively get involved in the aforementioned coordination mechanisms to intervene and regulate the green channel so as to promote the smooth operation of green supply chain.
