按照参与回收废旧产品的回收主体的不同,将企业废旧产品的回收模式分为生产企业自建回收系统模式、外包回收模式和生产企业联盟回收模式,分析了各类回收模式的特点.从收益决策出发,构建了延伸生产者责任(EPR)制度框架下企业回收模式决策模型,讨论、说明了不同回收模式下生产企业可能实现的最大收益及其条件.最后,得到了利用回收材料生产新产品实现的材料费用节约是企业回收利润的增函数以及回收联盟的生产规模决定回收材料成本的结论. The recycling modes of EOL products are divided into three kinds, i.e. the producer's self-recycling, outsourcing and alliance organized by several corporations. With the characteristics of the different recycling modes discussed, a decision-making model is developed within the framework of EPR(extended producer responsibility) for the recycling behavior of enterprises in view of the decision on benefits, then the maximum benefit and the conditions under which it is available are discussed and expounded for different recycling modes. Such a conclusion is therefore drawn that the cost saving as a result of recycling materials is an increasing function of the profit arising from the recycling behavior of an enterprise and that the scale structure of a recycling alliance determines the cost for material recycling.
