| 研究開始時の研究の概要 |
With the rapid adoption of electric vehicles (EVs) in cities, its impact on people's daily life and urban space has been a heated debate among scholars and policy makers. This research aims to contribute to our understanding of the long-run impact of EV adoption on urban-space economy. We build an urban economic model with land market, agglomeration economies and traffic pollution, and disclose the economic mechanisms through which EV adoption affects urban spatial structures. Moreover, we provide quantitative results and aim to analyze the urban policies that help achieve sustainable cities.

| 研究実績の概要 |
In the first year, I have investigated how the location patterns of electric vehicle (EV) users affect the total traffic pollution externalities and land rent revenues in monocentric cities. My research result shows that the urban spatial structure with EV users residing in the suburban districts (instead of the center) is associated with higher economic efficiency. From a perspective of policy establishment, my findings suggest that the increased land rent revenues may be taxed by local governments to subsidize suburban residents in buying EVs or to invest in building charging stations, achieving higher efficiency. The research findings have been summarized and published by highly regarded journal.

理由
In the first year, I have investigated how the location patterns of electric vehicle users affect the outcomes of an urban-space economy by building a monocentric urban model. By applying a linear urban economic model, and with high analytical solvability, the theoretical analysis goes smoothly. The initial results show that the location patterns of EV users exert significant impact on traffic pollution and urban land revenues. In particular, the urban spatial structure with EV users residing in the suburban districts (instead of the center) is associated with a better urban environment and higher land rent revenues.

| 今後の研究の推進方策 |
In the next year I plan to further investigate how the location of public charging stations affects EV adoption, land rent revenues and welfare levels in monocentric cities. Currently, I have obtained some initial results which show that the location places of public charging stations exert impact on not only EV adoption, but also the total welfare levels in equilibrium of the monocentric cities. I attempt to further calibrate the model with data to quantitatively investigate the optimal location of the public charging stations in different parameter configurations.
