Evolutionary Game Among Green Supply Chain Enterprises Under Fair Preference Conditions The Study

With the gradual maturity of the economic globalization trend,my country’s economic strength has been steadily improved,but with it comes increasingly serious ecological and environmental problems.In addition,the awakening of global environmental awareness makes my country’s commodities face severe challenges from international "green trade barriers".Under such pressures,the green transformation of the supply chain and the green transformation of upstream and downstream node enterprises in the supply chain have become a prerequisite for sustainable development of enterprises.However,the operation and management research of traditional green supply chain companies are all done on the basis of the assumption of "rational brokers".However,with the development of behavioral economics theory with the characteristics of bounded rationality,researchers have found that decision makers are in the process of decision-making.Central society is affected by the characteristics of limited rational behavior such as fair preference and strong reciprocity.In view of this,this article takes the green fairness preference of supply chain companies as an important driving force for the implementation of green supply chain as the starting point,considers the role of government control conditions in promoting the implementation of green supply chain by supply chain node companies,and deeply explores the behavior evolution of green supply chain implementers,In order to provide a reference basis for the government and business operation decision-making in practice.The research topic of this article is the influence of two factors,green fairness preference and government control mechanism,on the implementation process of green supply chain.The main research contents are as follows:First of all,this article introduces the fairness preference factors of enterprises into the decision-making process of a two-tier supply chain including manufacturers and sellers(distributors and retailers),and specifies the direction of their preference,that is,the degree of green investment of enterprises.And the fair preference of the green contribution of the supply chain,and then take the profit optimization of the supply chain members as the optimal decision-making goal,and construct the main enterprise of both parties under the condition of fair preference for the green input of manufacturers and sellers and the green contribution of the supply chain The evolutionary game model between the two,and finally the evolutionary equilibrium analysis.Secondly,on the basis that the decision-making of supply chain enterprises is driven by the enterprise’s green fairness preference,the government control conditions are introduced,the evolutionary game model between enterprises under the government control mechanism is established and the evolutionary equilibrium point is analyzed,so that the original evolutionary game model is more in line with Realistically,discuss the impact of government rewards and punishments on corporate decision-making.Third,use MatLab software to perform numerical simulation analysis on the model to verify relevant research conclusions.Finally,suggestions are made from two aspects: promoting supply chain node enterprises to actively carry out green transformation,improving government-related policies and regulations,and clear incentives and penalties.The results show that the existence of fairness preference promotes the implementation of the green supply chain.The larger the coefficient,the greater the probability that the company will actively implement the green supply chain;at the same time,when the government fines are higher than the company’s use of "free rider" When the difference between the amount of income obtained by the method and the increase in income after the green transformation,manufacturers and sellers will tend to carry out green transformation;in addition,when government subsidies can make up for the green transformation of manufacturers and sellers Costs,and the amount of subsidies can encourage manufacturers and sellers to take "free-riding" means that the increase in revenue is less than the increase in revenue after green transformation,such an incentive mechanism can effectively promote manufacturers and sellers to take the initiative in green Transformation.
