Abstract: To delve into the library fire evacuation behavior under the intrinsic mechanism, this paper considers the inadaptability, adaptability and significant impact on evacuation decision-making six psychological latent variables, using structural equation model analysis the intrinsic relationship between psychological latent variables influencing evacuation decision-making behaviors in the process of evacuation, and explores the influence of personal attributes on different psychological latent variables. The results show that inadaptive panic has significant positive effects on herd, inertia and altruistic adaptive evacuation psychology. The inadaptive inertia psychology has a significant positive effect on the inadaptive herd evacuation psychology while has a significant negative effect on the altruistic adaptive evacuation psychology. Risk perception has a significant impact on the inadaptive inertia psychology. Environmental familiarity has a significant positive impact on the herd, inertia inadaptive evacuation psychology, and altruistic adaptive evacuation psychology. The personal attributes of evacuees have different degrees of influence on some psychological latent variables. Women have higher risk perception, panic and altruism. The results can provide a theoretical basis for fire emergency evacuation planning.
