In the study of institutionalization in authoritarian regimes, non-repressive institutional pillars in non-democratic governance are often neglected. Through the research on the People's Republic of China's two rounds of reinstitutionalization in natural disaster management, a life or death issue for all Chinese dynastic regimes, this article aims to make contributions to new institutionalist studies of authoritarianism that help to explain the Chinese Communist Party's 'authoritarian resilience'.
