Optimizing Operation Of New Energy Vehicles Under Dual Credit Policy

With the rapid development of national economy in recent years,the scale of automobile industry has changed greatly,followed by environmental pollution and the shortage of non-renewable resources.New energy vehicle(NEV),as an alternative,can effectively alleviate environmental pollution and energy crisis,which has been recognized as the future direction of development in automobile industry.However,NEVs are in the initial stage of growth,compared to conventional vehicle(CV),the overall cost of NEVs still remains higher,and its market demand shows volatile and fluctuant.Hence,the government issued the dual credit policy in 2018 to promote the development of NEVs.There is no doubt that the implementation of dual credit policy has changed the external environment for automakers' decisions.However,previous papers on the NEVs' production mainly considers the impact of subsidy policy,while few scholars study the impact of the newly dual credit policy on automobile firms and consumers' choices.Based on subsidy and dual credit policy,this paper considers stable and unstable need for automobiles respectively to analyzes the influence of the above two policies on the structure of automobile industry and consumer purchasing,as well as the optimal productions of NEVs and CVs firms,and finds out the preconditions of the two policies that can promote NEVs' development.This dissertation discusses the influence of dual credit policy on the optimal production pricing strategy of NEVs and CVs firms,and analyzes the circumstances in which dual credit policy is more effective or subsidy policy is more promotive.Find that subsidy policy is valid to promote NEV's penetration only when the unit cost of NEV is high as well as the cost gap between NEV and FV is large.Additionally,the battery recycling rate is the most crucial element influencing the NEV firm's competitive status.Furthermore,dual credit policy can improve the technology of NEV and CV simultaneously,which compensate for the disadvantages of the current subsidy policy.In addition,the demand spillover effect appears only by increasing the rate of battery recycling under dual credit policy.Then,this dissertation analyzes the optimal NEV credit strategy of NEV firm and CV-NEV firm,and the impact of NEV credit trading price,the consumers'environmental awareness on the optimal production decision-making in the early stage of NEVs.Firstly,due to the low technology level of NEVs and CVs,as well as the NEV market and dual credit policy are not mature and perfect,so it is more appropriate to adopt the purchasing strategy.Secondly,when consumers have higher environmental awareness or seem to be more willing to buy NEVs from NEV firm,the self-producing strategy is more beneficial to NEV firm than the purchasing strategy.In addition,owning to the imperfection of dual credit policy and the immaturity of the NEV credit trading price,the government should actively guide and establish a platform mechanism.Finally,the dissertation further studies the production scheduling decision of the NEV firm based on across-chain under dual credit policy.We find that under the multiple production period,implementing dual credit policy increases the profit of the NEV supply chain,but profits of the CV supply chain and whole supply chain system decline simultaneously.Secondly,dual credit policy promotes the development of NEVs,forcing CV makers to develop their own NEV business in the long run.In addition,government should intensify subsidies for charging station construction in the future and design a mechanism under which CV makers should annually take out a part of profits to construct charging station during the transitional period.Researches made by scholars at home and abroad on NEVs are mainly empirical now.This paper takes the NEV firm,the CV firm,consumers and the government as the research subjects,and uses Operations Research and Game Theory to explore the influences of subsidies and dual credit policy on the production of NEVs and CVs firms,so as to provide the automobile supply chain with richer evidence and new perspective under dual credit policy.In addition,this paper finds out the preconditions that subsidy and dual credit policy promote the development of NEVs,and relevant conclusions can provide decision-making reference for policy-making departments.
