Research On Coordination Of Supply Chain With Capital Constraint Under Carbon Emission Abatement Cost Sharing

Emissions of CO2 and other greenhouse gases are a major challenge for the world,and“carbon reduction” has become a global consensus.Building a sound “green supply chain” is the key for all fields and industries to achieve a comprehensive carbon peak.From the practice of large leading enterprises at home and abroad,such as Wal-Mart,BMW,Shougang Group,“supply chain collaborative emission reduction” is becoming an important measure for the green upgrading of supply chain.At the same time,the above emission reduction activities are often accompanied by the application of new technologies,new processes,new materials,etc.,which brings financial pressure to many small and medium-sized manufacturing enterprises in the supply chain.Therefore,how to coordinate complex operations(production,ordering,pricing),emission reduction and financing decisions among supply chain members,and how to establish a collaborative emission reduction mechanism to promote the green upgrading of lowcarbon supply chain and the simultaneous improvement of economic benefits are urgent problems facing both theory and practice.In this paper,the above problems are abstracted into two types of “low-carbon supply chain finance(LC-SCF)system” for research.Under the premise of considering the low-carbon preference of consumers,a carbon emission dependent manufacturer with financial constraints is taken as the basic decision-making body.First,the scenario of the downstream large retailer providing one-way carbon emission reduction cost-sharing contract for the manufacturer is studied.The supply chain financial system of “a competitive bank-a large retailer-a capital constrained manufacturer” is built to solve the game equilibrium of all parties and the coordination strategy of the system.Then,considering the scenario that upstream large supplier and downstream manufacturer provide two-way carbon emission reduction cost-sharing contracts with each other,a supply chain financial system of “a competitive bank-a large supplier-capital-a constrained manufacturer” is arranged to solve the game equilibrium of all parties and the coordination strategy of the system.This paper also concentrates on the effects of the carbon trading market on the decision-making and coordination of these two types of low-carbon supply chain financial systems.The results show that:(1)In the supply chain finance system of “a competitive bank-a large retailer-a capital constrained manufacturer”,a set of combined contracts consisting of wholesale price,one-way carbon emission reduction cost sharing and production subsidies can achieve system coordination and Pareto optimization of each member’s profit;When the carbon trading market is further considered,additional single carbon trading cost sharing contract can be introduced to achieve system coordination.(2)In the supply chain finance system of “a competitive bank-a large supplier-a capital constrained manufacturer”,a set of combination contracts consisting of wholesale price,two-way carbon emission reduction revenue sharing and cost sharing can realize system coordination and Pareto optimization of each member’s profit;When the carbon trading market is further considered,it is necessary to introduce additional two-way carbon trading cost sharing contract to achieve system coordination.(3)While realizing Pareto optimization of system profit,the above combination contract can improve the carbon emission reduction level of supply chain,reflecting the dual economic and environmental value of combination contract.
