Abstract:  To improve the poor performance of electric vehicle market, a trilateral game model involving government, enterprises and consumers is established based on dynamic game with perfect information. Analyses on the equilibrium solution indicate that better performance in electric vehicle marketing can be achieved by robust stratagem, which aims at reducing the hidden cost in electric vehicle producing and consuming phases. To enhance the market performance effectively, it is suggested to introduce a policy mix, which guarantees an incremental government support with higher quota of investment on infrastructures, and to establish the penalty mechanism against petrol vehicle pollution as soon as possible.
