Carbon Emissions And Carbon Trading Decisions In The Supply Chain With Nashbargaining Fairness Preference

With the increasing concern about global warming,reducing greenhouse gas emissions which led by carbon dioxide has become a consensus among the international community.Paris Climate Conference reached a new global climate agreement called "Paris agreement",it showed that human beings has taken a historic step in dealing with climate issues.Domestic and foreign scholars did research into the supply chain contract in the past few years and made a lot of results,but most of the research are assumed that the decision makers are perfectly rational: That is,the decision maker always takes the maximum benefit as the code of his behavior.However,in recent years,some researches on human behavior factors which conducted by domestic and foreign scholars suggested that when considering behavioral factors,decision makers not only pursue maximum profits,but also consider that whether the income distribution is fair or not,whether it has risk or not.All the studies of the traditional supply chain have provided a new research topic.In the first part,we study the one-to-one supply chain structure when the supplier provides the wholesale price contract to the retailer.In the study of the existing low carbon supply chain decision-making,the question of fairness preference is neglected,and the Nash bargaining solution is used as a fair reference Standard.Based on the wholesale price contract to build Stackelberg game model,to obtain carbon emissions and wholesale prices and other supply chain decision-making,and analysing the effect of fairness preferences and carbon trading.The study found that the increase of carbon trading prices and the awareness of fairness preference of supply chain members would reduce the carbon emissions of suppliers,and the carbon trading price and the supply chain members’ awareness of fairness preference would also impact on the wholesale price and sales price.In the second part,on the basis of the first part,the author introduced the revenue sharing contract,and studied the contract of the revenue sharing contract which is less studied at present.Through the model analysis and numerical analysis,this paper discussed the influence of the carbon trading price,the fairness preference and the proportion of revenue sharing on the supply chain decision making under the revenue sharing contract.The study shows that the increase in carbon trading prices,supplier’s fair preference intensity and the reduction in the share of revenue share will reduce the carbon emissions of suppliers.The impact of retailers ’fairness preferences on suppliers’ carbon emissions depends on the specific market conditions.All the factors including the price of carbon trading,the proportion of revenue sharing and the fairness preference of the supply chain members will have an impact on the wholesale price and the selling price.By comparing the optimal decision under the revenue sharing contract and the optimal decision under the wholesale price contract.It is found that regardless of whether the main body of the supply chain is fair or not,under the background of carbon emissions trading,the carbon emissions under the wholesale price contract are lower than the carbon emissions under the revenue sharing contract,and two contracts under the wholesale price and sales price level will depend on the specific market.In the third part,on the basis of the first part,two pricing contracts are introduced to study the supply chain decision problem.The results suggested that the fairness preference of supply chain members does not affect the carbon emissions,wholesale prices and sales price decisions of suppliers and retailers.No matter whether the supplier has a fairness preference,the supplier will set the fixed fee charged to the retailer as far as possible to obtain a larger profit.When the retailer has a fairness preference,the supplier will consider the fairness preference for the retailer when a fixed fee is charged to the retailer.By comparing the optimal decision under the two pricing contracts and the optimal decision under the wholesale price contract.It is found that regardless of whether the main body of the supply chain is fair or not,under the background of carbon emissions trading,the carbon emissions under the wholesale price contract are lower than the carbon emissions under the two pricing contracts Two price contract,and two contracts under the wholesale price and sales price level will depend on the specific market.At the same time,by comparing the optimal decision under the two pricing contracts and revenue sharing contract,it is found that the wholesale and selling prices of the two contracts will depend on the specific market regardless of whether the supply chain subject has a fair preference,When the fair preference is not taken into account and only the supplier’s fair preference is taken into account,the carbon emissions of the revenue sharing contract will be lower than the carbon emissions under the two pricing contracts.When only the retailer’s fair preference is taken into account,The size of the emissions will depend on the specific market situation.This paper,combining with the traditional supply chain contract and fairness preference,enriches the traditional supply chain decision theory and the supply chain contract theory.Besides,this paper,based on the background of carbon emissions carbon trading band the national carbon trading market will establish in 2017,has the guiding significance of practice.
