| Abstract: | Calculating the external benefits of sharing electric vehicles (EVs) is the base of setting the relevant incentive policies for EVs adoption. To make clear how much the externality is, this paper measures the substitution rate of sharing EVs to urban internal combustion vehicles (ICVs), in which the substitution rates of the two typical sharing modes: self-service electric vehicles and ride-sourcing electric vehicles are measured separately. Based upon the results of the substitution rate, both the environmental benefits and the public infrastructure benefits of sharing EVs, are calculated, including the effect of curtailing pollution gas emission and mitigating traffic noise as well as the benefits of relaxing the demand pressure of public infrastructures such as road and parking spaces. The research results indicate that self-service EVs are currently more popular in the market than ride-sourcing EVs; from the perspective of the overall external benefit, the significant part is reflected in the aspect of reducing urban road demand. |
