Research On The Impact Of Carbon Cap And Trade Mechanism On The Performance Of Automobile Supply Chain

This paper studies the financing decision,carbon emission abatement and production decision optimization of capital constrained automobile supply chain under carbon cap and trade mechanism.Specific research contents and innovative work are as follows : this paper constructs a kind of automobile supply chain decision model :including a supplier with certain initial capital but facing financial constraints and a downstream vehicle enterprise.The vehicle company first determine carbon emission reduction and production decisions.Secondly,the supplier determine their own production and independent carbon emission reduction according to the strategy of the vehicle enterprise,and the initial capital-constrained supplier can obtain bank loans by pledging a certain amount of carbon emission permits to the bank to solve the problem of capital constraints.Based on carbon emission permits trading and initial capital level,this paper gives the optimal solution of production and carbon emission reduction decision of automobile supply chain under decentralized decisions and centralized decisions,and studies the profit change of the capital-constrained supplier when choosing carbon asset pledge financing.Finally,based on the supplier ’s bankruptcy risk,this paper gives the expected profit function of the bank and the solution of the bank pledge ratio,and analyzes the functional relationship between the supplier ’s carbon emission reduction,production decision and bank expected profit.This paper studies the impact of carbon trading price on profits,production and carbon emission reduction decisions of the supplier and the vehicle enterprise,the impact of carbon elasticity of the supplier and the manufacturer on expected profits,production and independent carbon emission reduction investment of the vehicle enterprise and the supplier,and analyzes the impact of supplier production and carbon emission reduction decisions on bank profits.The research results show that the production of the supplier increases with the increase of carbon emission reductions of the supplier and the vehicle enterprise.When the initial capital of suppliers is greater than the sum of production and carbon emission reduction costs,the profit of the supplier decreases with the increase of carbon trading price.The relationship between the profit of the vehicle enterprise and the trading price of carbon emission permits is related to the initial capital of the supplier.This paper provides a theoretical basis for automobile supply chain decision-making under carbon cap and trade mechanism,and has strong practical significance.
