“…Another stream of literature closely related to our paper is the studies on the nonsubsidized policies for EVs, for example, building EV charging stations (Aghalari et al, 2021; Kumar et al, 2021; Liu et al, 2023; Yu et al, 2022), license plate (Li, Jiao, & Tang, 2019; Xian et al, 2022), free parking and road toll (Zhang & Qin, 2018). A growing number of researchers have focused on the charging infrastructure, such as the optimal distribution of chargers (Kontou et al, 2019; Yang et al, 2017; Yi & Bauer, 2016; Yu et al, 2016) and the investment model (Kumar et al, 2021; Wang & Deng, 2019; Yu et al, 2022).…”
