Research On Subsidy Of New Energy Vehicles Based On Government Budget Constraints

With the energy shortage,automobile exhaust and other environmental problems more and more serious,governments began to develop new energy industry.New energy vehicles have being supported by our government as a pillar industry in China.In the early stage of the new energy automotive industry,government offer subsidies to stimulate the development of new energy automotive industry.However,subsidies to consumers,retailers or manufacturers,can achieve the maximum sales under the government budget constraints.This is the issue we discussed in this thesis.Firstly,we consider the fixed subsidies and ad valorem subsidies to establish a classic newsboy model.To compare the optimal sales of the new energy vehicles and the optimal level of subsidies under the government budget constraints and consumer subsidies,dealer subsidies and manufacturers subsidies respectively.Then we find that,the Government will choose a fixed price subsidy in order to improve the market of new energy vehicles production.Secondly,we study the stochastic demand,the optimal decision analysis process under the budget constraint and the consumer subsidy,dealer subsidy or manufacturer subsidy respectively.Through the model,compare the optimal yield and profit of different subsidy objects.Then,it was verified by numerical study.The results show that the effect of manufacturer subsidies and dealer subsidies is the same,the government will subsidies to consumers to improve the market of new energy vehicles supply.Finally,in the case of consumer subsidies,consider the manufacturer is the risk aversion,the optimal subsidy and the relationship between production and risk aversion coefficient under the government budget constraints;then we also take into account the shortage cost,the impact on the decisions of the manufacturer and the government.Finally,conforming the influence of the relevant parameters by numerical analysis.
