Research On Closed-Loop Supply Chain Recycling Decision Under Consumer Environmental Protection Awareness

The rapid development of science and technology and the continuous improvement of people’s living standards have accelerated the upgrading of electronic and electrical products,and have resulted in a large number of waste electrical and electronic equipment(WEEE).Waste electrical and electronic products not only pollute the environment but also cause the waste of renewable resources.Therefore,the recycling of used electronic and electrical products has become a social problem that needs to be solved.Consumers,as the main players in market activities,are gradually aware of the environmental problems brought about while they are enjoying increasingly rich material products.Therefore,when consumers purchase products,they begin to pay attention to the degree of environmental protection and the use of products.The problem of recycling and disposal plays an important role in the formation of a green supply chain.Therefore,when the environmental awareness of consumers changes,the product demand function of the closed-loop supply chain and the recycling function of used products will change accordingly.Based on the above background,the issue of recycling decision-making was studied based on consumer awareness of environmental impacts on recycling functions and demand functions.The following two parts were mainly studied:(1)Considering that consumer environmental awareness affects product recycling,a closed-loop supply chain consisting of recycling platforms,manufacturers,and retailers is established to study the issue of decision-making on the recycling of used products under the government’s differential subsidy mechanism.Two kinds of subsidy mechanisms are analyzed: the government directly subsidizes the manufacturer’s remanufacturing(GM mechanism)and the government’s direct subsidy recovery platform(GP mechanism),and establishes a corresponding decision model,and verifies the correctness of the model and conclusion through numerical examples..The research shows that government differential subsidies can effectively increase the recycling price,recycling amount,manufacturer’s transfer payment,manufacturer’s profit,and profit of online recycling platform for online recycling platforms.Under the two subsidy mechanisms,the service level of online recycling platforms varies.The wholesale price,retail price,and retailer’s profit are only related to the production cost of new products,and have nothing to do with the differential subsidy coefficient,the consumer’s sensitivity to environmental protection awareness of the recycling of used products,and the consumer’s sensitivity to online recycling platform services;The size of the subsidy coefficient and the sensitivity of the consumer to the service have a great influence on the effect of the two subsidy methods.(2)Under the circumstance that consumers’ environmental awareness influences product demand,a closed-loop supply chain hybrid recovery model was established.Three mixed structure recovery models were explored: Simultaneous recycling by manufacturers and retailers(MR models),simultaneous recovery by manufacturers and third-party recyclers(MT models),and simultaneous withdrawals by retailers and third-party recyclers(RT models),The results of the decision were analyzed through calculation examples.The results show that: With the increase of environmental protection awareness of consumers,the profits of all parties in the supply chain have increased,and the recycling rate of used products has increased accordingly;usually,manufacturers and retailers are willing to choose the MR model;In the case of third-party recyclers participating in recycling,manufacturers and third-party recyclers are willing to choose the RT model,and retailers prefer to choose the MT model.
