Research On Remanufacturing Decision-Making And Channel Structure Selection Of Competitive Closed-Loop Supply Chain Considering Environmental Taxes

This article combines the background of environmental taxes and the development of closed-loop supply chain remanufacturing,based on the competitive market environment,studies the impact of environmental tax policies on competitive companies and supply chain operational decisions and production pricing.This article discusses the remanufacturing closed-loop supply chain channel strategies under environmental taxes,and analyzes the social welfare under different environmental taxes and the optimal environmental tax to maximize social welfare.The main research contents of this paper are as follows: First,under the environmental tax policy,we study two competing companies decide whether to have recycling channels and remanufacture.By constructing a two-period decision-making model for the production of competing companies,we compare the production decisions and profits of companies participating in remanufacturing and not participating in remanufacturing,and analyze the critical conditions for companies to participate in recycling and remanufacturing decisions,and discuss the government’s optimal environmental tax policy from the perspective of social welfare.Second,under the environmental tax policy,we study the channel structure selection strategy of the manufacturer that is dominant in the two competitive closed-loop supply chains.We analyze the production decisions of supply chain members when the channels are vertically integrated under the environmental tax,as well as the equilibrium strategy from the perspective of the manufacturer and the supply chain profit,and discuss the social welfare under different equilibriums.Third,under the environmental tax policy,we study the retailer as the leader of the two supply chains,and analyze the channel structure selection strategy based on the closed-loop supply chain and the closed-loop supply chain.We study the impact of environmental taxes on closed-loop supply chain channel structure strategies,and discuss consumer surplus,environmental impact,social welfare and the optimal environmental tax to maximize social welfare under different equilibrium decisions.This research has certain theoretical and practical significance.From the corporate perspective,we consider the impact of environmental tax policies on corporate remanufacturing decisions and closed-loop supply chain channel decisions in a competitive market,provide guidance for supply chain companies’ operational decisions,and expand research on environmental policies and closed-loop supply chains;From the perspective of the government,it enriches the research on social welfare and environmental tax decision-making from the perspective of closedloop supply chain,provides a theoretical basis for environmental tax decision-making from a micro perspective,and has certain reference value for the government to apply environmental tax policies to improve social welfare.
