The low-carbon transition is a systemic economic and social change that will inevitably have an impact on many areas of the urban system. Among them, has China's ongoing low-carbon transition had an impact on urban resilience (UR) systems while achieving urban energy saving and carbon emission reduction goals? This paper uses the implementation of the carbon emissions trading pilot policy (CETPP) as a "quasi-natural experiment", and evaluates the impact of the policy on UR using a differencein-differences model based on the data of prefecture-level cities from 2011 to 2020. The study shows that pilot carbon trading policies have a favorable impact on UR, and the market mechanism of carbon emissions has a heterogeneous cause in uence on UR. The impact of pilot carbon trading policies on UR varies according to the respective moderating effects of institutional factors, green technology innovation, industrial structure rationalization, and output effects.Canada, the Adaptation to Climate Change Team (ACT) proposes to seek methods for low-carbonresilience in 2016 (He et al., 2020).
