In order to improve the efficiency of emergency knowledge in interpersonal communication, questionnaire and social network analysis were used on rural residents, and UCINET6.645 software was used to analyze the node's degree centrality, eigenvector centrality, betweenness centrality and the density of the emergency knowledge network transmission among residents from the perspective of interpersonal communication. Based on this, the emergency knowledge dissemination efficiency and its network structure were studied. The results show that: the emergency knowledge dissemination network of rural residents is sparse, and the awareness of interpersonal emergency knowledge communication needs to be improved. Residents with great influence on others in the network play an important role in the emergency knowledge dissemination network. Key residents can be used to promote the dissemination of emergency knowledge and culture.

Key words: social network, rural residents, emergency knowledge, transmission efficiency, interpersonal communication, degree centrality
