Research On Decision-Making Model Of Mobile Phone Closed-Loop Supply Chain Under Government Intervention

With the progress of science and technology and the development of economy,mobile phone has gradually become an indispensable convenience tool and social media in People’s Daily life.Consumers’ increasing demand for mobile phone functions has accelerated the speed of mobile phone replacement and stimulated the vigorous development of mobile phone recycling industry.However,there are many problems in the rapidly developing mobile phone recycling industry.Mobile phone recycling industry lacks formal recycling channels and professional disposal means,informal recycling channels have the risk of personal information disclosure,and unprofessional disposal means lead to serious environmental pollution and resource waste.In order to solve the problem of mobile phone recycling industry development,the state carried out government intervention.However,the progress of intervention mechanism is slow,the form is simple,and the effect is not good.Therefore,how to stimulate the mobile phone recycling industry,to get rid of the industry development dilemma,has become an urgent problem to be solved.In recent years,the research on mobile phone recycling has been concerned.However,the comprehensive study on the waste mobile phones as waste electronic products lacks the characteristics of mobile phone recycling industry.And research tends to recycle channels of competition and cooperation.Compared with other electronic products,mobile phones have a larger amount of scrap and high remanufacturing value.The research should focus more on the value utilization after recycling.This paper combines the characteristics of mobile phone recycling industry,considers remanufacturing and return,builds a decision-making model of mobile phone closed-loop supply chain,and puts forward two government mechanisms,namely reward and punishment mechanism and environmental tax + recycling subsidy mechanism,to encourage the development of mobile phone closed-loop supply chain,to encourage the development of mobile phone closed-loop supply chain,the research of this paper has enriched the research of closed-loop supply chain and has practical significance for enterprise management adjustment and government optimization.The specific content of this paper is as follows:Firstly,considering remanufacturing,it constructs the decision-making benchmark model of mobile phone closed-loop supply chain.The value of recovered products includes remanufacturing value and disassembly value.According to the degree of cooperation between manufacturers and retailers,they can be divided into decentralized decision making and centralized decision making.In decentralized decision making,manufacturers and retailers cooperate to maximize their own interests.In centralized decision-making,manufacturers and retailers cooperate with the goal of maximizing the overall profit of the supply chain.The optimal decision parameters and profit function under two kinds of decisions are solved,and the three models are compared and their profit overlap points are solved.Then,on the basis of the benchmark model,it establishes the mobile phone closed-loop supply chain decision-making model under the mechanism of reward and punishment and environmental tax + recycling subsidy.In the reward and punishment mechanism,the government implements the reward and punishment mechanism for the manufacturer.The actual recovery rate is compared with the target recovery rate.The excess part is rewarded according to the recovered quantity,and the insufficient part is punished according to the recovered quantity.In the mechanism of environmental tax + recycling subsidy,the government implements environmental tax on the manufacturer according to the amount of recycling,and grants recycling subsidy to the consumer according to the amount of recycling.The optimal decision parameters and profit function under decentralized decision and centralized decision are solved,the influence of government intervention mechanism on the decision parameters is studied,the three models are compared and their profit overlap points are solved.Finally,the paper summarizes the research results and puts forward suggestions for enterprise management and government management based on the results.From the perspective of enterprises,enterprises should participate in recycling actively,improve remanufacturing technology,and strengthen industry cooperation;From the government’s point of view,government should implement diversified intervention,make rationalization measures,and stimulate the development of the industry comprehensively.The results of this paper show that:(1)Remanufacturing ratio is positively correlated with profit function.(2)Both the reward and punishment mechanism and the environmental tax + recycling subsidy mechanism are conducive to improving the recovery rate and obtaining higher recycling profits.However,both intervention mechanisms lead to lower sales.Manufacturers and retailers raise wholesale and selling prices to make up for the loss of sales profit from lower volumes.Different from the reward and punishment mechanism,the environmental tax + recovery subsidy mechanism can affect the transfer payment price and recovery payment price.(3)When the value of government intervention mechanism is within a reasonable range,the profit of government intervention mechanism is greater than that of the benchmark model.There are overlapping points in model profits.
