In order to further promote the development of electric vehicles

a method for estimating the ownership of electric vehicles is pro posed considering the master-slave game of carbon trading among the government

suppliers

and consumers. Firstly

based on the interests of the three parties

a master-slave game model led by the government is established. Secondly

considering the innovation

imitation effect

and price factors of the population

the Bass model is improved to predict the regional electric vehicle ownership. Furthermore

the utility functions of the three parties in the game are optimized as the objective function

in order to obtain the basic data under the Nash equilibrium solution for the parameters of the Bass model. And then

establishes a regional electric vehicle ownership prediction method is established by alternating between ownership prediction and vehicle market game simulation. Finally

with actual vehicle data from Shanghai

the impact of introducing carbon trading into the vehicle market on the number of electric vehicles is analyzed in the coming years.Through scenario comparison

the feasibility and economy of the proposed method are verified.
