Abstract: Few studies have explored the impact of trans-regional power transmission on urban energy system resilience. In this study, a time-varying difference-in-differences (DID) model was used to evaluate the impacts of trans-regional power transmission on the urban energy system resilience. The results show that the impact of trans-regional transmission on the resilience of urban energy systems is heterogeneous. Specifically, for the northern region, which is dominated by thermal power generation and output, trans-regional power transmission contributes to enhance the urban energy systems resilience. However, for southwestern regions, trans-regional power transmission has damaged the urban energy systems resilience. This conclusion remains valid after a series of robustness tests. This suggests that trans-regional power transmission may bring inequalities in regional energy utilization. Therefore, the economic compensation to power exporting regions should be increased. In the context of rapid industrial development, the active development of renewable energy and the expansion of power input channels in the western region are recommended. In addition, all cities should be encouraged to develop microgrids to improve the ability of urban energy systems to absorb risks.
