Research On Reverse Supply Chain Contract Under Asymmetric Information

With the rapid development of economy and technology,more and more waste products are increasing rapidly.As a result,these waste products aggravate environmental pollution and waste of resources.It is an effective way to sovle the problem of environmental pollution and waste of resources by carrying out recycling waste products and remanufacturing activities.On this basis,China has promulgated a series of policies to encourage enterprises to carry out recycling of waste products.Recycling of waste goods is the first step in reverse supply chain,so it is more important to study reverse supply chain.Because of the problem of asymmetric information in the reverse supply chain,it will reduce the operation efficiency of the reverse supply chain and reduce the profits of the supply chain members.Therefore,the design of reverse supply chain contract under asymmetric information has the research value on the efficiency of reverse supply chain,national economic development and environmental protection.Based on the background of recycling of waste electrical and electronic products,a reverse supply chain consisting of a manufactuer and a recycling agent is established.Through revenue sharing contract,manufactures are encouraged to recycle their recyclability efforts to achieve the goal of improving the efficiency of the reverse supply chain,the profitability of each member and the protection of the environment.Based on the current situation of domestic and foreign research,this paper combines the theory of reverse supply chain,game theory and principal-agent model.In this paper,we introduce the recovery quantity as a nonlinear function about the degree of effort.We design the optimal contract under the symmetric information,the moral hazard problem under asymmetric information of linear fusion contract and the adverse selection and moral hazard under asymmetric information problems exist linear separation of contract.In this paper,the supply chain contract of asymmetric information is solved by nonlinear transformation into linear method and graphic method.Firstly,the advantages and disadvantages of the two methods are discussed by numerical analysis,and then the influence of relative parameters on optimal contract is analyzed.Under the hypothesis of this paper,we conclude that the recycle chamber chooses the contract,the manufacturer chooses to separate the contract,and the linear separation contract can well identify the recyclers' capabilities.
