Abstract: Due to their high-density, mixed and disordered spatial morphology and complex social structure, urban villages have become vulnerable links in the public safety systems of megacities. This study takes four typical urban villages in Fengtai, Changping and Chaoyang Districts of Beijing as empirical cases and constructs a ‘perception-space-management' collaborative analytical framework. Through questionnaire surveys and exploratory factor analysis, four factors influencing residents' fire safety satisfaction are identified: built environment morphology, fire safety perception, fire safety management and physical comfort. Meanwhile, space syntax is adopted to conduct topological modeling of village road networks, quantitatively analyzing morphological indicators such as integration, intelligibility, control value and depth value. The study finds that there is a significant correlation and discrepancy between spatial morphology and residents' safety perception: areas with high integration may show low satisfaction due to ineffective daily management (e.g., road occupation); areas with low integration and high depth value (e.g., Feijia Village) achieve high satisfaction through advanced technical and human-based prevention systems. Based on this, differentiated renovation strategies are formulated according to village types, aiming to realize the organic integration of spatial layout optimization, organizational process reengineering and management mechanism innovation, and provide decision-making support and implementation paths for refined and differentiated fire safety governance of urban villages in megacities.
