Research On Supply Chain Decision-making Of New Energy Vehicles Based On Tripartite Evolutionary Game

At present,the national financial subsidies for new energy vehicles have completed the decline,and in this context,the new energy vehicle industry has gradually shifted from policy-driven to market-driven.Affected by the decline of subsidies,the main behavior strategies of the national government,new energy vehicle enterprises and consumers have changed.In this regard,based on the tripartite evolutionary game model,this thesis hopes to clarify the problems existing in the current industrial development by comparing the changes in the behavior and decisionmaking of each participant in the new energy vehicle market before and after the decline of national financial subsidies,and use the knowledge of supply chain management to make suggestions on the supply chain decision-making of new energy vehicles to ensure the stable development of the industry.This thesis first summarizes the current development of the national new energy vehicle industry,clarifies the objects and methods of national financial subsidies,and analyzes the shortcomings of the current development of the new energy vehicle industry in combination with the current market situation after the decline of financial subsidies.At the same time,combined with the research content,this thesis also studies the supply chain management mode of new energy vehicles,and finds that there are two types of oriented supply chain decision-making methods in the current industry,namely government-oriented and consumer-oriented.By summarizing the results of previous domestic and foreign research theses,this thesis determines the theoretical basis and clarifies the research methods and steps.Then,this thesis takes the research scenarios before and after the decline of national financial subsidies as the research scenarios,and constructs an evolutionary game model based on the government,new energy vehicle enterprises and consumers.By analyzing the return matrix and evolutionary game conditions of each subject,this thesis summarizes the evolution path of the three-way game subject,and simulates the specific process of evolutionary game by numerical substitution simulation.By comparing the different behavioral decision-making methods of the three parties before and after the decline of financial subsidies,this thesis concludes that first,the development of China’s new energy vehicle industry will go through four stages,and the order of evolution is from the government to consumers to manufacturers;Second,the decline of national financial subsidies has the greatest impact on consumers’ purchasing decisions,and after the subsidy declines,the market demand for new energy vehicles will decline significantly;Third,after the subsidy decline,manufacturers will adopt a conservative product pricing strategy to stimulate market demand,but this behavior will lead to vicious price competition between car companies on the one hand,and is not conducive to the healthy development of the industry on the other hand.Finally,aiming at the development status of the new energy vehicle industry mentioned above,combined with the method of sensitivity analysis,this thesis clarifies the main factors restricting the development of the industry,and believes that the new energy vehicle supply chain must be optimized in upstream product design and research and development,midstream green production and smart logistics,downstream product marketing and brand building,and puts forward specific optimization measures.In order to ensure the effectiveness of the optimization measures,this thesis uses the simulation method to make a test and analysis,and the results show that the supply chain decision-making method proposed in this thesis can effectively solve the dilemma of industry development and maintain the healthy development of the industry.
