Abstract: To research the effect of social responsibility on decision-making and profitability of Closed-Loop Supply Chain (CLSC),and to coordinate the CLSC with social responsibility,a CLSC model consisting of one manufacturer and one retailer was constructed.Under centralized decision-making and decentralized decision-making with manufacturer leading Stackelberg game,the decisions of pricing,social responsibility investment and return rate were studied and compared respectively.The impact of social responsibility effect on decision variables and profits of CLSC system was analyzed.The coordination of two-part tariff contract and revenue sharing contract with decentralized decision CLSC was investigated .The numerical analysis was presented to demonstrate the conclusions,and the results showed that the total profit in decentralized decision-making was less than that in centralized decision-making,all decision variables and profits of the CLSC were positively correlated to social responsibility effect.The coordination of CLSC was achieved with two-part tariff contract and revenue sharing contract,while the revenue sharing contract was more flexible.

Key words: closed-loop supply chain, social responsibility, Stackelberg game, two-part tariff contract, revenue sharing contract
