Impact of the dual-credit policy on electric vehicle diffusion considering information transmission.

China has enacted the dual credit policy to enhance electric vehicle (EV) diffusion, and the impact of information transmission on manufacturers' decisions has not been well considered under the policy compliance pressure. We developed a complex network-based evolutionary game model to study the proliferation of EVs under the dual credit policy and explore the impact of different information transmission mechanisms. Our results suggest that stricter enforcement of corporate average fuel consumption credit requirements can promote the effective diffusion of EVs. Surprisingly, increasing the EV credit ratio requirement does not significantly promote the EV proliferation. Credit prices play a crucial role in policy effectiveness. Furthermore, our study highlights the heterogeneous effect of information transmission on policy effectiveness, which indicates a dual effect of industry information. Mixed information transmission can combine the advantages of both modes, avoiding crowding-out effects while reducing volatility and maximizing the benefits of information transmission.
