摘要
针对废弃电器电子产品(WEEE)回收处理问题,从利润最大化视角构建生产商和回收商的最优决策模型,探讨政府财政调控对两类企业决策行为的影响及其对WEEE规范处理的作用。研究中假定生产商可以采用两种方案生产产品,一是生产全新产品,不采用任何回收的零部件;二是生产商优先采用回收零部件生产产品,不足部分将购买新零部件。研究结果表明,生产商和回收商在推进WEEE的回收处理业务中存在合作条件,当回收零部件的价格在上下限范围时,双方具有合作意愿,而政府则可以通过财政调控措施增强双方的合作空间,引导双方在WEEE的规范处理和循环再利用中付出共同努力。
To investigate waste electrical and electronic products(WEEE) recycling,the optimal decision models of manufacturer and recycler are constructed from the perspective of profit maximization.The cooperative conditions between manufacturer and recycler as well as the influence of government intervention are discussed.It is hypothesized that manufacturer has two choices in production:they can produce products by using new parts or by using recycled parts in priority.The results show that there are cooperation conditions between manufacturer and recycler in promoting WEEE recycling.When the price of recycled parts is within the upper and lower limits,manufacturer and recycler have motivation to cooperate.Moreover,the government can inspire their cooperation by financial intervention,and guide manufacturer and recycler to make joint efforts in contributing WEEE recycling.
