Research on the evolution mechanism of the electric vehicle market driven by big data

This paper focuses on analyzing the effect of Government incentive policy on car producers under big data background. Driven by big data, the producers can effectively predict the consumers demand on EV. We research on the mechanism of government subsidies and carbon tax influence on producers' decision-making by establishing an evolutionary game model between governments and producers, and integrating with prospect theory, we get a Perceived Benefit Matrix which is different from the traditional payoff matrix to research the behavior of the government and the producer decision-making. Theoretical study and simulation show that, under static subsidies and carbon tax, there does not exist real Nash equilibrium in evolution system, and the initial state affects the track of evolution system; only when the government intervention cost and subsidies are less than carbon tax and the different profit between producing electric vehicle and fuel vehicle is greater than actual input, the evolution system will have a stable state, which the producers would produce electric vehicle under government intervention; the system is more sensitive on the degree of perceived value and degree of loss aversion, so it is more important to strength the producers confidence in producing electric vehicles; raising the subsidy and carbon tax policies can induce producers to choose producing electric vehicles, and in these measures, producers are more sensitive in carbon tax.
