The Competition And Cooperation Between Enterprises Under The Supply Chain Carbon Finance

With population growth and economic development,the mode of production is from slash-and-burn become the large-scale industrialization and personalized customization.Accompanied by large energy consumption,the emissions of carbon dioxide and other greenhouse gas emissions are increasing greatly.Large amounts of greenhouse gas emissions caused lots of climate issues.Such climate problems are threating the sustainable development of national economy and the human ecological environment.Therefore,low carbon economy and sustainable development are being widely discussed and researched.Along with the determination of the Kyoto protocol and other international agreements which are aimed at reduce emissions,lots of countries have passed their own carbon reduction policies.Cap and trade system has been widely used.Under this policy,enterprises are being charged by emitting CO2.That causes stress on enterprise's cash flow.We research how enterprise choose suitable financing way and cooperation level in order to optimize supply chain profit under carbon capand-trade policy.This research has important theoretical and practical value.At the beginning,this paper summarized the current development of carbon finance,and then compared the different among common bank loans,carbon finance and trade credit by Mathematical model.Compared to traditional finance,carbon finance is easier to realize and can help company to expand market.But it maybe not the best choice of every enterprise.So this paper put forward such a new carbon finance model,which is combined the advantages of supply chain finance and carbon finance.This paper research how this supply chain carbon finance model effect the supply chain profit and reduction rate.In the final,this paper used game theory to establish a supply chain model,used the Mathematica software to do simulation.By comparing supply chain carbon finance model,traditional finance and internal supply chain finance,this paper try to solve the problem about how to the enterprise choose the suitable financing way and cooperation level when facing the cap and trade policy.This research put forward a new carbon finance model.Using this supply chain carbon finance model,supply chain can allocate the carbon reduction fund with the goal of maximizing the supply chain profits.Through Mathematical modeling and numerical example,this paper proved that supply chain finance model can help firms to resolve their finance problem,generate their enthusiasm for carbon reduction.
