Research On The Pricing And Recovery Model Of Closed-loop Supply Chain Considering Blockchain

In the context of the rapid development of the Internet,with the gradual improvement of garbage classification awareness in China,intelligent recycling has been applied in more and more cities,and more and more people choose intelligent recycling methods.Compared to traditional recycling in the past,intelligent recycling is more convenient and can be recycled in a single quantity.Traditional recycling mainly focuses on centralized recycling,and intelligent recycling can achieve cumulative recycling through APP points,such as receiving cash or exchanging items.Intelligent recycling not only provides convenience to consumers,but also provides new development opportunities for manufacturing enterprises.However,due to prominent issues such as information asymmetry and information opacity in closed-loop supply chains,third parties are prone to exploit information vulnerabilities to lower recovery prices,resulting in consumers having difficulty trusting recyclers.The application of blockchain technology can just solve this problem.Blockchain technology can improve consumers’ trust in recyclers by improving the information transparency and security of closed-loop supply chains.It is not only conducive to improving third-party recovery rates,but also conducive to alleviating the plight of manufacturing enterprises in declining profits due to asymmetric recovery information,thereby improving the overall efficiency of the supply chain.Based on this,it is of great significance to comprehensively consider blockchain technology and recycling models,and analyze the impact of blockchain applications on closed-loop supply chain pricing and recycling model decisionmaking.Therefore,in the closed-loop supply chain system composed of a manufacturer,a retailer and a third-party recycler,this paper takes the manufacturer as the Stackelberg game leader,through the comprehensive use of theoretical knowledge and methods such as game theory,operational research,Maple solution and example analysis,and by introducing parameters such as the sensitivity coefficient of consumers to the level of information sharing,the one-time cost of blockchain,and the authenticity coefficient of information,Analyze and explore the impact of adopting blockchain technology and different recycling modes on closed-loop supply chain management decisions.The main research work of this article is as follows:First of all,when manufacturers do not introduce blockchain technology,they distinguish between three different modes of traditional recycling without blockchain technology,intelligent recycling without blockchain technology,and hybrid recycling without blockchain technology.Stackelberg game is used for equilibrium solution and comparative analysis.Secondly,when manufacturers introduce blockchain technology,they differentiate between three different modes: traditional recycling using blockchain technology,intelligent recycling using blockchain,and hybrid recycling using blockchain.Stackelberg games are used for equilibrium solution and comparative analysis.Finally,compare the supply chain decision-making problems under three different modes before and after the blockchain is adopted.According to the equilibrium solution results,use the numerical simulation method to more intuitively and comprehensively display the decision analysis process,which is conducive to the supply chain members to make the best choice.The main conclusions of this article are as follows:(1)Without using blockchain technology,the sensitivity coefficient of consumers to the level of information sharing and the authenticity coefficient of information are directly proportional to the profits of each member of the supply chain;The profit of third-party recyclers is always the highest in the mixed recycling model.When the sensitivity coefficient of consumers to information sharing level is less than a certain threshold,manufacturers and retailers have the highest profit in the traditional recycling model;When the sensitivity coefficient of consumers to the level of information sharing is greater than a certain threshold,manufacturers and retailers have the highest profits under the mixed recycling model.(2)In the case of adopting blockchain technology,the sensitivity coefficient of consumers to the level of information sharing is directly proportional to the profits of each member of the supply chain;The profits of supply chain members are not affected by the authenticity coefficient of information and the moral hazard coefficient of third-party false information.When a manufacturer introduces blockchain technology,the smaller the fixed one-time payment,the greater the manufacturer’s profit;The profit of third-party recyclers is always the highest in the mixed recycling model.When the sensitivity coefficient of consumers to information sharing level is less than a certain threshold,manufacturers and retailers have the highest profit in the traditional recycling model;When the sensitivity coefficient of consumers to the level of information sharing is greater than a certain threshold,manufacturers and retailers have the largest profits in the mixed recycling model.(3)Longitudinal comparative analysis of pricing decisions and profits under different recovery modes: Regardless of the mode,manufacturers’ profits decrease as the fixed one-time fees paid by manufacturers introducing blockchain technology increase,and the profits of retailers and third-party recyclers are not affected by the fixed one-time fees paid by manufacturers introducing blockchain technology.In the traditional recycling model,when the sensitivity coefficient of consumers to information sharing level is greater than or less than a certain threshold,the profits of manufacturers,retailers,and third parties using blockchain technology are greater than those not using blockchain technology;In the intelligent recycling mode,when the sensitivity coefficient of consumers to information sharing level is greater than or less than a certain threshold,the profits of manufacturers,retailers,and third parties using blockchain technology are greater than those not using blockchain technology;In the mixed recycling mode,when the sensitivity coefficient of consumers to the level of information sharing is greater than or less than a certain threshold,the profits of manufacturers and retailers using blockchain technology are greater than those not using blockchain technology,and the profits of third parties are always greater when using blockchain technology than not using blockchain technology.
