The management of sudden public crisis in super large residential communities has always been a difficulty in the field of emergency management. Through sorting out the emergency management mode and governance logic of China’s super large residential communities, combined with the analysis of typical public events, the paper sums up the four types of emergency barriers that currently exist in China’s super large residential communities, namely, “management black box”, “structure embedded”, “load overload” and “ownership decline”, and analyzes the reasons for their occurrence. On this basis, the paper puts forward the principles that should be followed by agile governance, such as principle traceability, subject coordination, structural advantages, etc., and explores the practical path to build the agile governance of public crisis in super large residential communities from the perspectives of system, technology, organization, culture, etc.
