Study On The Network Construction Of Reverse Supply Chain For Electronic Product And The Incentive Mechanism

With the rising of the concept of circular economy, and the enhancement of the whole society's awareness of environmental protection, the problem of electronic waste (e-waste) has become the focus of the whole world's attention. Especially the promulgation of two directives of EU (WEEE&RoHs) has caused great impacts on Chinese electronic industry. As the important way for circular economy and the sustainable development, end-of-life electronic product recycling has broad prospects for development. However, its implementation is usually hinged by its economic and environmental conscious from the participants of the reverse supply chain. Therefore, it's necessary to study the network construction of reverse supply chain in electronic product recycling, and how to stimulate enterprises to implement e-waste recycling.In this thesis, the major researching jobs are: the reverse supply chain network for electronic product based on extended producer responsibility (EPR) and service supply chain (SSC) ; price strategy based on a three-level reverse supply chain benefit model made up of a manufacturer, a retailer and a service center on condition that information is symmetrical; comparison of efficiency of reverse supply chain between non-cooperation mechanism and cooperation mechanism, and two incentive mechanisms to coordinate; signal transfering game between the service centre and the retailer in the case that the demand information of re-used market is asymmetrical; incentive mechanism of manufacturer to maximize its benefits when the cost information is asymmetrical; discussion on the equilibrium strategy and moral hazard between the manufacturer and the retailer based on the two-level reverse supply chain with introduced advertising parameter and recycling effort parameter; contents of the utility function of the government when it takes financial subsidies policy to the recycling enterprises, and the optimal incentive contract. During the study, two kinds of method are mainly used; those are incentive theory (the principal-agent theory) and the optimization of operations research methods. Through discussion, this thesis acquires some results such as: the recycling networks of reverse supply chain for electronic product based on EPR and SSC, including the model operated by the manufacturer itself, and the model operated cooperatively; comparison of efficiency of the benefit model between the cooperation mechanism and non-cooperation mechanism in three-level reverse supply chain, and an incentive mechanism to improve coordination in the case that information is symmetrical; the way to solute the participants' equilibrium strategies in the case that re-used market's demand information is asymmetrical; the way to design the optimal incentive contract for the manufacturer when the recycling cost information is asymmetrical; the government's integrated benefits include economic benefits and environmental benefits; the optimal incentive contract for government's subsidies policy.
