Urban Affairs Review, Ahead of Print.
An increasing volume of literature has sought to identify factors that motivate cities to pursue sustainability and adopt climate policies. However, most empirical studies were done in Western countries, where relatively high local autonomy and low pressure on industrial growth create conditions for spontaneous policy innovations in sustainability. This paper uses China’s Low-Carbon City Pilot Program as a case to investigate motivations for local sustainability actions in an authoritarian context. Our event history analyses confirm the effects of multi-level governance on local sustainability initiatives in China, particularly horizontal competition across jurisdictions, priorities and preferences of upper-level authorities, as well as local determinants including leadership, capacity, politics, and environmental stress. The findings contribute to the comparative urban governance scholarship by highlighting the unique feature of “experimentation under hierarchy” in shaping urban sustainability policymaking in China.
