Research On The Operation Of Closed-loop Supply Chain For Recycling And Remanufacturing Of Waste Electrical And Electronic Products

Due to the improvement of living standards and the national publicity work in place,people pay more and more attention to health and gradually enhance their awareness of environmental protection.In order to comprehensively utilize resources and promote the development of circular economy,the state also pays more and more attention to the recycling of waste electrical and electronic products.In recent years,the increase in the number of waste electrical and electronic products has not only caused serious pollution to the environment,but also affected the recycling of resources.At present,many responsible enterprises have realized the importance of corporate social responsibility(CSR).They do not hesitate to sacrifice part of their profits to bear social responsibility.However,some enterprises cannot bear corporate social responsibility in time because of insufficient economic strength and small scale.Therefore,the government,as a macro regulator,gives certain economic support to enterprises,which can make up for the loss of interests when enterprises bear social responsibility and help enterprises improve their enthusiasm to bear CSR.Based on this background,this paper takes the manufacturer as the leader in the closedloop supply chain,and studies the operation of the closed-loop supply chain considering government subsidies and CSR investment level when the market demand is deterministic and uncertain.Based on Stackelberg game theory and utility theory,this paper constructs a single third-party and double third-party recycling and remanufacturing closed-loop supply chain operation model considering CSR and government subsidies under deterministic market demand,and analyzes the impact of government subsidies,consumers’ sensitivity to CSR and third-party competition coefficient on the closed-loop supply chain;Under the uncertain market demand,the degree of risk preference of manufacturers,sellers and third parties is easier to show.Sellers play a risk averse role in the supply chain.The loss averse utility function is used to measure the degree of risk aversion of sellers.The operation models of single third-party and double third-party recycling and remanufacturing closed-loop Supply Chain Considering CSR and government subsidies are constructed,and the competition coefficients of government subsidies and third parties are analyzed The impact of CSR investment level and risk aversion characteristics of sellers on closed-loop supply chain.Finally,taking ZW company as an example,this paper analyzes the impact of government subsidies and enterprise CSR investment level on enterprise income and price,verifies the effectiveness of the model constructed in Chapter 3 and 4,provides reference for enterprise decision-making and government work,and gives reasonable countermeasures and suggestions.The results show that:(1)the expected profit obtained by the manufacturer decreases with the increase of the seller’s aversion to risk,the downward trend of contract coordination is slower than that of decentralized decision-making,and the risk aversion characteristics of the seller will be lower and higher in decentralized decision-making and contract coordination,indicating that the revenue cost sharing contract can weaken the impact of the seller’s risk aversion characteristics on the profits of each node enterprise in the supply chain.(2)Recycling competition does not affect the profit,order quantity and wholesale price of sellers.Appropriate competition is conducive to the improvement of profits of manufacturers and the whole supply chain,the full utilization of resources and the improvement of ecological environment.(3)The purchase behavior of consumers is affected by the behavior of enterprises.Manufacturing enterprises bear social responsibility,and the order quantity of consumers will continue to increase,which will bring good reputation to themselves,enhance the competitiveness of enterprises,and be conducive to the benign development of enterprises.(4)The government’s subsidy to enterprises in the closed-loop supply chain can share part of the CSR input cost for manufacturing enterprises and increase the profits of enterprises,which is conducive to promoting enterprises to actively assume social responsibility.Taking this as a long-term decision,the profits of recyclers will increase,improve the enthusiasm for recycling waste products and improve environmental performance.
