China vigorously promotes taxi electrification in some cities due to increasingly severe energy and environmental problems. However, there is still a lack of research comparing fuel taxi electrification paths. Our study compared the comprehensive benefits of Beijing's taxi electrification paths from the perspective of the taxi and taxi energy-supply stations. In addition, a sensitivity analysis of the economic benefits of the two electrification paths was conducted. The results show that the economic and environmental benefits of electric taxis are significantly better than those of fuel taxis. The economic and social benefits of battery-swapping stations are also better than those of battery-charging stations. This study verifies that the electrification of the fuel taxi is a more environmentally friendly and economically feasible initiative and that the battery swapping path is better than the battery charging path.
