摘要： Climate change mitigation policies must be developed to reduce the adverse effects of escalating climate risks. However, climate policies are fraught with uncertainty, which leads to unavoidable negative consequences. It is crucial to understand the impact of climate policy uncertainty on urban climate risk. This study uses the entropy weighting method to measure the urban climate risk of 274 prefectural-level cities in China from 2011 to 2021 based on the Hazard-Exposure-Vulnerability (H-E-V) adaptation decision-making framework, and employs the two-way fixed effects model to investigate the impact of climate policy uncertainty on urban climate risk through multidimensional empirical tests. The results indicate that: (1) Climate policy uncertainty significantly increases the level of urban climate risk. (2) Climate policy uncertainty affects the level of urban climate risk through the industrial structure of the production sector. (3) Deposit balances and insurance cost of the household sector exacerbate the positive relationship between climate policy uncertainty and urban climate risk. (4) Climate policy uncertainty has a greater impact on climate risk in capital cities than in non-capital cities and it has the most significant impact in cities with medium level of climate risk. The findings offer new perspectives on reducing urban climate change risk and achieving sustainable development.
