【摘要】：工业革命以来,电子垃圾已成为世界上增长最快的垃圾,且由于社会资源的紧张和保护环境的需要,各国对废旧电器电子产品的回收利用都给与高度的重视。而如何对废旧电器电子产品进行回收和再处理已经成为关系我国社会、经济以及环境可持续发展的重要问题,我国提倡建立资源节约型、环境友好型社会,这使得传统的供应链已经不能满足这种要求,而闭环供应链正好是这一号召的实际运用,其中政府是不可或缺的角色。本文主要运用动态博弈方法研究了在制造商竞争情形下,电子类废旧产品闭环供应链的制造商回收再制造的决策问题。论文设计讨论了三种机制,即税收—补贴机制、数量折扣机制以及押金返还机制,每一种机制又分别建立三个模型进行探讨,即制造商垄断情形下闭环供应链决策模型(基础模型)、政府在制造商竞争情形下对制造商实施机制的闭环供应链决策模型、政府在制造商竞争情形下对回收商实施机制的闭环供应链决策模型,并分别计算、比较和分析了三种机制下的最优决策结果。研究表明:税收—补贴机制下,随着单位补贴的提高,回收率会逐渐提高,回收商利润逐渐增加,在政府对制造商采取税收—补贴机制时,回收再制造的制造商的利润逐渐增加,在政府对回收商采取回收—补贴机制时,回收再制造的制造商的利润逐渐下降;数量折扣机制下,随着价格折扣率的增加,回收率会逐渐降低,回收再制造的制造商和回收商利润先降低后增加;押金返还机制下,随着单位押金的增加,制造商竞争环境下的回收率、回收再制造的制造商和回收商的利润逐渐增加,而制造商垄断情形下的回收率、回收再制造的制造商和回收商利润基本不变。此外,提高回收再制造的成本优势可以提高回收率。
[Abstract]:Since the Industrial Revolution, electronic waste has become the fastest growing garbage in the world, and due to the shortage of social resources and the need to protect the environment. Many countries attach great importance to the recycling of waste electrical and electronic products. However, how to recycle and reprocess waste electrical and electronic products has become a concern in our society. Economic and environmental sustainable development of important issues, our country advocates the establishment of resource-saving, environment-friendly society, which makes the traditional supply chain has been unable to meet this requirement. The closed-loop supply chain is precisely the practical application of this call, in which the government is an indispensable role. This paper mainly uses the dynamic game method to study the situation of manufacturers' competition. This paper designs and discusses three mechanisms, namely, tax-subsidy mechanism, quantity discount mechanism and deposit return mechanism. Each mechanism is discussed by establishing three models separately, that is, the closed-loop supply chain decision model (the basic model) under the condition of manufacturer monopoly. The closed-loop supply chain decision model of the government in the case of manufacturer competition and the closed-loop supply chain decision-making model of the government implementing the mechanism to the recycler in the case of manufacturer competition are calculated separately. The results of optimal decision under three mechanisms are compared and analyzed. The results show that under the tax-subsidy mechanism, with the increase of unit subsidy, the recovery rate will gradually increase, and the profit of the recycler will gradually increase. When the government adopts the tax-subsidy mechanism to the manufacturer, the profit of the manufacturer of recycling and remanufacturing increases gradually, and the profit of the manufacturer of recycling and remanufacturing decreases gradually when the government adopts the mechanism of return-subsidy to the recycler. Under the quantity discount mechanism, with the increase of the discount rate of price, the recovery rate will gradually decrease, and the profit of manufacturers and recyclers of recycling and remanufacturing will decrease first and then increase; Under the deposit return mechanism, with the increase of the unit deposit, the recovery rate in the competitive environment of the manufacturer, the profit of the manufacturer and the recycler increases gradually, and the recovery rate under the monopoly situation of the manufacturer. The profit of manufacturers and recyclers for recycling and remanufacturing is basically unchanged. In addition, increasing the cost advantage of recycling and remanufacturing can improve the recovery rate.
