中文摘要：

针对由一个履行社会责任的供应商,另一个存在违背社会责任风险的供应商,单生产商和两类顾客组成的供应链模型,考虑单源采购和不同顾客支付意愿的异质性,研究生产商的采购决策、目标市场选择以及定价策略决策。研究发现：在责任供应链中,生产商的采购决策与顾客支付意愿最大值及采购成本差异有关,而目标市场和定价策略的决策仅与顾客支付意愿最大值有关;当顾客支付意愿最大值越大,生产商偏向于责任采购;当供应商之间的采购成本差异越大时,生产商偏向于非责任采购;在责任采购模式下,当顾客支付意愿最大值较小时,大众市场下的价格歧视策略为优势策略;当顾客支付意愿最大值较大时,大众市场下的统一定价策略为优势策略。

英文摘要：

In a supply chain consisting of a responsible supplier,an irresponsible supplier,one manufacturer,and two types of consumers,and considering sole sourcing and heterogeneity of customers＇ willingness to pay,this study investigates the manufacturer＇s optimal decision of sourcing,target market selection and pricing.Results show that the manufacturer＇s sourcing strategy depends on the maximum of customers＇ willingness to pay and the difference of sourcing costs from two heterogeneous suppliers.However,the target market selection and pricing strategies only depend on the maximum of customers＇ willingness to pay.As the maximum of customers＇ willingness to pay increases,the manufacturer prefers responsible sourcing,but as the difference of sourcing costs increases,the irresponsible sourcing is preferred.In the mode of responsible sourcing,when the maximum of customers＇ willingness to pay is small,price discrimination in mass market is optimal,however,when the maximum of customers＇ willingness to pay is large,extension pricing strategy in mass market is optimal.
