| Outline of Annual Research Achievements |
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.

2: Research has progressed on the whole more than it was originally planned.
Reason
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.

| Strategy for Future Research Activity |
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.
