| After more than 20 years of rapid development of China’s automobile industry,the scale of the automobile market continues to expand,and now the recycling and recycling of waste tires has gradually become an urgent problem to be solved in the development of the industry.The recycling of waste tires is not only the need for efficient use of resources,but also the need for environmental protection.To this end,from the perspective of retreading and reusing old tires,this thesis considers the participation of Internet platforms in recycling and government subsidies,and studies the pricing decisions of relevant entities in the supply chain of old tire recycling.First of all,the paper elaborates the connotation and method of waste tire recycling,discusses the recycling mode and reuse mode of waste tire,and analyzes the development status of waste tire recycling industry and government policies and laws and regulations of waste tire industry.Secondly,for the situation of no government subsidies,considering the two recycling channels of retailers and Internet platforms,respectively,model A and Model B models are constructed for whether retailers and Internet platforms cooperate in reverse channels,compare and analyze the optimal decisionmaking of sales channels and recycling channels under the two models,and discuss the cooperation and non-cooperation on the reverse channels of retailers and Internet platforms on sales prices,wholesale prices,recycling prices,recycling transfer prices,sales volumes,recycling quantities,The impact of manufacturer profits and the profits of retailers and Internet platforms is discussed,and the impact of the number of old tires voluntarily returned by consumers on the pricing decisions and profits of manufacturers,retailers and Internet platforms is discussed.Then,for the case of government subsidies,four models of Model 1,Model 2,Model 3 and Model 4 are constructed for different objects of government subsidies,and the optimal decision-making of forward channels and reverse channels under the four models is compared and analyzed,and the influence of the selection of government subsidy objects and the influence coefficient of government subsidies on retail prices,wholesale prices,recycling prices,recycling transfer prices,sales volumes,and recycling amount equilibrium solutions,manufacturers,retailers,Internet platforms optimal profits and social welfare are discussed.The main conclusions of the model analysis are: whether retailers and Internet platforms cooperate in reverse channels has no impact on positive channel pricing and sales;cooperation between retailers and Internet platforms on reverse channels has a negative impact on manufacturers’ profits;if retailers and Internet platforms do not cooperate,if the two recycling prices are adjusted by the same range,the recycling volume of Internet platforms is more affected;the recycling transfer price of manufacturers is higher when retailers and Internet platforms cooperate on recycling channels;the government has a higher recovery transfer price for manufacturers,retailers,Internet platforms and consumer subsidies will have a positive role in promoting the improvement of social welfare;when the government subsidy impact coefficient is a certain time,the government chooses to subsidize manufacturers to be most beneficial to consumers;Government subsidies to manufacturers,retailers,Internet platforms and consumers have a positive effect on the growth of manufacturers’ profits,retailers’ profits,and Internet platform profits;when the government subsidy impact coefficient is fixed,the government subsidies to retailers when the Internet platform recovers the lowest amount,and the government subsidies to the Internet platform when the retailer recovers the lowest amount. |
