Abstract: Under cap-and-trade regulation,parameters such as Corporate Social Responsibility (CSR) investment level,carbon emission reduction cost coefficient and low-carbon promotion cost coefficient were introduced,and the Stackelberg game was used to compare and analyze the effect of manufacturers,retailers and third parties recycling on the decision of closed loop supply chain under CSR investment by manufacturers or retailers.The results showed that under CSR investment of manufacturer,the manufacturer's profit was the highest when retailer was recycling.Under CSR investment of retailer,the lower the cost of remanufactured products,the highest of manufacturer's profit when retailer was recycling;on the contrary,only when the cost saving of remanufactured products was large,the manufacturer's profit that was the highest when manufacturer was recycling.It was found that whether CSR investment was made by manufacturer or retailer,the level of carbon emission reduction and the level of low-carbon promotion efforts were affected by the cost savings of remanufactured products.The waste recovery,retailer's profits and system social welfare were the highest when manufacturers was recycling,and the profit of the third party was the highest with itself recycling under CSR investment of retailer.The enhancement of the CSR investment level caused the decrease in CSR investor's profit,but the increase in the profits of other members and system social welfare.The improvement of the carbon emission reduction cost coefficient would lead to decrease in each member and system social welfare.As the low-carbon promotion cost coefficient improving,only retailers would increase own profits when it invested in CSR,while other profits and system social welfare would decrease.

Key words: corporate social responsibility investment, carbon emission reduction, low-carbon promotion, closed-loop supply chain, recycling

摘要： 在碳总量控制与交易机制下,引入企业社会责任(CSR)投入水平、碳减排成本系数及低碳推广成本系数等参数,运用Stackelberg博弈对比分析了制造商投入CSR和零售商投入CSR下制造商、零售商和第三方分别回收对闭环供应链决策的影响。结果表明:制造商投入CSR下,制造商利润在零售商回收时最高;零售商投入CSR下,再制造品节约的成本较小则制造商利润在零售商回收时最高,反之则制造商利润在自身回收时最高;无论制造商还是零售商投入CSR,碳减排水平和低碳推广努力水平都受再制造品节约的成本影响,废旧品回收率、零售商利润和系统社会福利均在制造商回收时最高,第三方回收时自身利润在零售商投入CSR下最高;随着CSR投入水平提高,制造商或零售商投入CSR均会导致自身利润降低,但会提高其他成员利润及系统社会福利;随着碳减排成本系数增大,各成员利润和系统社会福利均会减少;随着低碳推广成本系数增大,只有零售商投入CSR时自身利润会增加,其他情形利润和系统社会福利均会减少。
