摘要
用博弈论建立了含有政府、多家制造商和消费者的供应链模型,研究政府以旧换新政策及其社会福利、供应链关键变量对以旧换新政策和供应链成员的影响。研究得出了不同条件下的政府最优决策,发现政府以旧换新政策会提高社会福利,降低废旧品的环境危害和处理成本能增加社会福利,过高的市场竞争会降低社会福利。
We established a game modelfor a supply chaincontaininga government,manufacturers and customers to study the government's optimal trade-in policyand its social welfare,key variables influences on the trade-in policy and supply chain members.We got the optimal trade-in policies for different cases and found thatthegovernment's trade-in policy will increase the social welfare,and that the decreasing of the environment cost derived from waste and the treatment cost of waste will increase the social welfare as well,but that over much competition among manufacturers will result in the decline of social welfare.
