为激励电器电子产品生产企业积极回收并有效处理电子废弃物,电子废弃物许可证管理制度是一种有效的措施.构建多成员企业的闭环供应链网络,分别分析了守约和违约两种情形下的闭环供应链网络成员企业的均衡条件,给出了变分不等式框架,构建了两种情形下的成员企业博弈模型,分析许可证制度下成员企业的行为反应.在此基础上,提出了模型的求解算法,最后提出算例计算并对比分析了两种情形下的博弈模型结果.发现:守约情形下,如果电子废弃物排放许可证初始分配满足环境目标,则政府部门指定的环境标准可以达成;若政府处罚力度不够,成员企业在利润的驱使下会选择超额排放;提高单位处罚成本,成员企业会选择减少违约排放量;违约情形下,建立合理的惩罚框架可以保证成员企业不出现违约行为.
In order to encourage electrical and electronic product manufacturers to actively recover and effectively handle electronic waste, the e-waste permit management system is an effective measure.Constructing the closed-loop supply chain network of multi-member enterprises, the two cases of compliance and default are analyzed respectively Under the equilibrium conditions of member firms in closed-loop supply chain networks, a framework of variational inequality is given, and the game model of member firms in two situations is constructed to analyze the behavior responses of member firms under the permit system. On this basis, Finally, the calculation of the model and comparison of the results of the game model under the two cases are also made.It is found that under the compliance situation, if the initial allocation of the eWG permits to meet the environmental goal, the environmental standards Can be reached; if the government penalties are not enough, member companies will be driven by profits will choose excess emissions; improve unit penalty costs, member companies will choose to reduce emissions of default; under the circumstances of default, the establishment of a reasonable punishment framework to ensure that member companies do not appear Breach of contract.
