Abstract: For study the carbon emission reduction and low-carbon promotion in closed loop supply chain,a game model of closed loop supply chain was developed under four different Stackelberg structures (vertical Nash,retailer-led,manufacturer-led and centralized decision),and the optimal decisions and optimal profits of four different Stackelberg structures were comparative analysis.The corresponding decentralized structures were coordinate by Shapley value method and shared system revenue increment mechanism,and the member's profits were compared before and after coordination.The research showed that,for decentralized structures,the low-carbon promotion effort,carbon emission reduction level,collection level,retail price and supply chain entire profits were best under vertical Nash structure;the wholesale price and manufacturer's profits were best under manufacturer-led structure;the retail margin and retailer's profits were best under retailer-led structure.Two coordination mechanisms could effectively increase the profits of manufacturer and retailer under the decentralized structures.The coordination effects of two coordination mechanisms on the profits of manufacturer and retailer under the decentralized structure were compared by numerical analysis.
