1、 摘 要 近 20 年来,科技创新和个性需求促进电子产品消费需求快速增长的同时也导 致大量的废弃电子的产生,对人类和自然环境产生致命的污染和危害。在此背景 下,电子产品的闭环供应链的协调问题引起了各国政府及学术界的关注,研究发 现由于闭环供应链的各成员存在自利性,会致使供应链的总利润降低,因此良好 的协调机制、公正独立的主体有助于实现供应链系统收益最大化。 本文以电子易逝品为研究对象,对电子易逝品的特性进行分析和研究,给出 与其特性匹配的函数表达式,并进行论证,在考虑政府参与和不参与两种情形基 础上,分别建立含单、两零售商电子易逝品闭环供应链协调模型,研究两种情形 下电子易逝品的回收再制造收益
2、和回收率水平,分析电子易逝品闭环供应链收益 和回收率在不同税收和补贴政策下的变化,探讨政府如何通过税收和补贴政策, 向政策受益者征税和向受损者补贴,促使制造商、零售商、回收商更加努力去回 收废旧产品,从而减少电子易逝品对生态环境和人事健康的影响,实现卡尔多 -希 克斯改进。 首先,针对电子易逝品生命周期短,期末残值高,需求不确定等特性,建立 电子易逝品的残值函数和模糊需求函数;分析政府参与电子易逝品闭环供应链协 调的原因和意义的同时给出了政府参与协调机制。 其次,建立基于单零售商的电子易逝品闭环供应链的协调模型,针对无政府 参与协调情形下分散式决策和集中式决策两模式,并考虑考虑政府参与协调情形
3、 分别建模和数值仿真得出:电子易逝品的残值和可再制造率与制造商、回收商和 零售商获得的收益及回收量成正相关;考虑政府参与协调情形下的电子易逝品闭 环供应链,让电子易逝品闭环供应链中各成员收益不少于协调前水平,能提高电 子产品的回收量和回收率,意味着政府参与协调能够减少对废旧电子对环境的污 染,增进了社会福利。 最后,针对销售市场竞争情况,建立含两零售商的电子易逝品闭环供应链协 调模型,模型中考虑无政府参与协调和政府参与协调两种情形,并进行模型对比 和数值仿真可知:相比于单零售商情形,制造商会根据两零售商竞争情 况调整批 发价格,竞争激烈则提高批发价格,反之降低批发价格;模型中通过政府税收补 贴
4、政策能够使制造商、零售商、回收商的利润和回收量均获得增加。 关键词 :电子易逝品;政府参与;闭环供应链协调;零售商竞争 ABSTRACT Over the past 20 years, the technological innovation and the individual needs promote the rapid growth of electronic products in consumer demand. While they also cause a lot of waste in electronic production which leads fatal pollu
5、tion and hazards to human and nature. Under such a background, the problem of closed-loop supply chain coordination in electronic products has draw attention of scholars at home and abroad. According to the previous studies, the selfish of the closed-loop supply chain members would reduce the total
6、profits in supply chain. Hence, a good coordination mechanism and an impartial subject are helpful to maximize the benefits of supply chain system. The thesis will take e-perishable goods as the object of this research, to analyze and study the characteristics of e-perishable goods and to establish
7、and demonstrate the matching function expression of characteristics. Considering that the government may participate or not, in this thesis two closed-loop supply chain coordination models with a single or two e-perishable goods retailer will be established separately. And the thesis will study the
8、recycling manufacturing revenue and recovery levels of e-perishable goods under these two cases, analyze the change of revenue and recoveries in the e-perishable goods closed-loop supply chain under the different tax and subsidies policies. It will also explore how the government, through imposing t
9、axes to the policy beneficiaries, setting subsidies to the losers by subsidies policy, prompts manufacturers, retailers, recyclers and consumers to recycle waste products harder, and therefore, reduces influence of the electronic perishable goods on the nature and health, and achieves the Kaldor - H
10、icks improvements. First of all, according to short life cycle, high final residual and uncertain demand of the electronic perishable product, the thesis will create the residual functions and fuzzy demand function of electronic perishable goods; analyze the reasons and significant of government par
11、ticipates in electronic closed-loop supply chain coordination, and give the coordination mechanisms of governments participation. Secondly, on the base of single retailer, the thesis will establish the electronic perishable goods closed-loop supply chain coordination model, for the two models of dec
12、entralized and centralized decision in governments participation or not, considering modeling and numerical simulation which the government participates in coordinating ,and the thesis will draw out that: the electronic perishable goods residual values and remanufacturing rate have a positive correl
13、ation with the amount of revenue and profit of manufacturers, recyclers and retailers; Considering the electronic perishable goods closed-loop supply chain under coordination of governments participation can make profit in each member of the electronic perishable goods closed-loop supply chain no le
14、ss than the previous income level, and increase the recycle amount and recovery rate of electronic products, which means that the coordination of government participant can reduce the environmental pollution caused by electronic waste, and improve the social welfare. Finally, for the competition of
15、sales market, the thesis will establish the coordination model of electronic perishable goods closed-loop supply chain on the base of two electronic retailer, which considers the governments participation or not, and the comparison of the two models and numerical simulation show that: compared to a
16、single retailer, the manufacturers will adjust the wholesale price according to the competition between two retailers, and the wholesale price will increase when competition is more intense. In this model, the tax subsidies of government policy can increase the profit of the manufacturers, retailers
