Research On Decision Model Of New Energy Vehicle Closed-loop Supply Chain Under Consumers’ Green Preference

As the country attaches importance to the environment and consumers’ awareness of environmental protection has increased,new energy vehicles(EV)have gradually become favored by consumers compared to traditional fuel vehicles(FV).The manufacturer has also taken consumers’ green preference behavior as a key factor in their production and decision-making.At the same time,the popularization of EV also makes the recycling of power batteries gradually attract the attention of the society.How to maximize the reasonable recovery and cascade utilization of power batteries has become the focus of many scholars and enterprises.From this perspective,this paper uses nonlinear consumer utility functions and dynamic game theory to study the decision-making research model of the closed-loop supply chain of new energy vehicles(EVCLSC)under the green preference of consumers.First,it studies the impact of different recycling modes and recycling quality on the equilibrium solution,the manufacturer and the collector’s profits and the utility of consumers under consumers’ green preferences.Then,when the recycling mode is determined,the subsidy and the green innovation behavior of the manufacturer under the consumer’s green preference will affect the equilibrium solution,profits of the manufacturer and the collector,and the utility of consumers.Finally,data simulation is used to prove the validity and correctness of the proposition.The conclusions drawn in this article include:(a)consumers’ green preference behavior has an adverse effect on the manufacturer,but it is beneficial to the collector and consumers.Cost sharing behavior is conducive to the profit of the manufacturer and consumer utility.When the sharing coefficient meets certain conditions,the profit of the collector will rise and then fall.In the such three situations,what is most conducive to the development of the EV market and consumer utility is that centralized decision,and cooperative recycling under decentralized decision is more conducive to the development of EV and the improvement of consumer utility.(b)the increase in the level of recycling quality is conducive to improving the profit of the manufacturer and the utility of consumers,but the profit of the collector needs to consider the thresholds of the recycling quality coefficient and the green preference coefficient.In the three cases,the recovery rate under centralized decision,the sales of EV,and the utility of consumers to EV have all reached the maximum.When the cost-sharing coefficient meets certain conditions,the recovery rate of cooperative recovery under decentralized decision is greater than the recovery rate under the sole recovery mode of the collector.(c)among the different government subsidy policies,to maximize the profit of the manufacturer and maximizing the utility of consumers,subsidizes to consumers is the best model.For the collector to maximize profits,the government can subsidize consumers or the manufacturer.Subsidies to the collector are not good for the development of the EV market.The sales of EV,the recycling rate,the collector and the manufacturer’ profits and the utility of consumers under the three scenarios all increase with the increase of government subsidies.However,excessive subsidies to collector will damage the profit of the manufacturer.(d)in the three cases,the recovery rate,sales of EV,profits of the collector and the manufacturer,and consumer utility all increase with the increase in the unit green innovation cost.Compared with the government subsidy level,the unit green innovation cost will have a greater impact on members of the EVCLSC.After the manufacturer’s technological innovations,to maximize consumer utility,subsidizes to the manufacturer is best.To maximize the manufacturer profits,subsidizing consumers or the manufacturer will be right,while subsidizing the collector is detrimental to the manufacturer’ profits and consumer utility.The paper has 36 pictures,1 table,and 100 references.
