Abstract: To research the influence of environmental benefits on optimal decision for green supply chain,a supply chain game model with profit and environment simultaneously considered by manufacturer was constructed based on multi-objective optimization and game theory,the decision for supply chain model under centralized,manufacturer-led Stackelberg game and profit-sharing contract was analyzed,and the above three equilibrium results were compared.The results showed that the manufacturer's profit would be reduced after considering the target of environmental benefits,while the retailer's profit,product greenness and environmental benefits was increased.However,a profit-sharing contract could realize multi-coordination of product green degree,profit and environmental benefits of the whole supply chain.

Key words: green supply chain, environmental benefits, multi-objective optimization, profit-sharing contract, game model
