Research On Two-level Low Carbon Supply Chain Decision Based On Mixed Carbon Policy

With the rapid development of low-carbon policies in the world,the Chinese government actively fulfills the responsibility of major countries and actively implements the implementation of the carbon trading market and environmental taxes.In this context,the implementation of the low-carbon policy has brought about major changes in the operational decision-making and management of enterprises,and supply chain enterprises should incorporate carbon emission reduction into production and operation decisions.In addition,the opacity of carbon information may trigger corporate misrepresentation and affect the entire supply chain.Therefore,the decision-making and false analysis of supply chain under the constraints of low-carbon policy is an important issue in supply chain management.This paper constructs a two-tier supply chain decision-making model led by a single manufacturer under the low-carbon policy,focuses on carbon information symmetry and retailers' carbon information misreporting,and discusses the optimal decision-making and coordination problems of supply chain enterprises under low-carbon policies.Firstly,this paper constructs two supply chain decision models under the constraints of carbon tax policy and mixed carbon policy,and uses the Stackelberg game to solve the model,and obtains the optimal order quantity and optimal emission reduction of manufacturers and retailers,then designs a reasonable revenue sharing coordination contract,and draws the optimal decision quantity of the supply chain enterprise and the coordination coefficient of the revenue sharing contract,which promotes the win-win situation of both enterprises in the supply chain and realizes the overall coordination of the supply chain.Secondly,this paper focuses on the behavior of carbon information false reporting by retailers,introduces the initial carbon emission falsehood coefficient,constructs a game decision model,and solves the optimal decision of the supply chain,analyzes the impact of retailers' carbon information misrepresentation on supply chain enterprises,and then uses the revenue sharing contract to circumvent the risk of false reporting.Finally,this paper carries out numerical simulation through relevant software to verify and analyze the model results.The research shows that under the condition of information symmetry,the optimal emission reduction of manufacturers,the optimal emission reduction of retailers and the optimal order quantity in the centralized decision-making of supply chain under the constraints of low-carbon policy are better than decentralized decision-making.And the revenue sharing contract can realize the coordination of the supply chain,eliminate the marginal revenue effect,and achieve the Pareto optimality.At the same time,the revenue sharing contract can also make the supply chain avoid the risk of false reporting.
