摘　　要：通过对目前家电产品的保有量、淘汰率、回收途径、回收量、处理方式等方面的研究,发现家电回收处理体系中政府的环保化回收量很少,私人的非环保化的回收方式占主导地位;由于对回收产品处理不当,造成的环境污染比较严重;通过建立系统动力学模型研究促进废旧家电环保化回收的策略尤为重要。本文以北京市废旧家电回收为例进行调研、绘制了废旧家电回收处理体系的存量流量图,给出了存量流量图的方程式,数值验证了模型的正确性;分析了政府实行政策调控并加强与家电品牌官方制造商、专业的回收处理企业的合作的策略,得出了该策略不仅能够增加政府环保化的回收量,而且能够实现合作整体利润增加的重要结论。该成果可为政府合理化废旧家电的回收处理体系提供借鉴。Improper treatment of recycled household appliances could cause serious environment pollutions.However,in the current recycling and treatment system,the government recycles only a small portion of used household appliances with environmental protection while the private section does a large portion of them without environmental protection.Therefore,it is appealing to study the strategies for recycling and treating used household appliances via building dynamic systems based models.In this study,Beijing’s recycling and treatment system of used household appliances is investigated,its inventory flow chat is created and the dynamic model of inventory flow is established.The numerical simulations illustrate the effectiveness of our model.Furthermore,analysis based on our model show that the collaborations among the government,the appliance manufacturers and the recycling companies can not only improve the recycling and treatment system with environmental protect,but also increase the profit of enterprises.The theoretic basis could be provided for the government to optimize the recycling and treatment of used household appliances.
