Quantifying the impact of climate policy uncertainty on integrated energy resilience in Chinese cities

With the gradual increasing concern about climate risks, few have paid attention to its potential role in integrated energy resilience. This study, thus, empirically examines the impact of the uncertainty of climate policy (UCP) on the energy resilience using panel data from 286 Chinese cities (2010–2019). The findings reveal that: (i) a 1 % increase in UCP is associated with a 0.897 % growth in urban IER; this implies that the uncertainty of climate policy substantially enhances urban energy resilience by improving the robustness and adaptability of energy systems (ii) three key mechanisms (i.e., energy technology innovation, energy supply diversification, and industrial transition acceleration); are identified. And (iii) the uncertainty of climate policy's positive effect on energy resilience is particularly evident in non-first-tier cities, mature and non-resource-based cities, Yangtze River Delta, Pearl River Delta, middle reaches of the Yangtze River Delta, and non-capital cities, while being insignificant in other city types. Based on these findings, targeted policy recommendations are proposed to enhance energy resilience.
