Abstract: Information transmission is of great significance for the government to effectively respond to public health emergencies. While screening information to form policy judgment resources, the government's ability to filter, screen, communicate and analyze information also needs to be strengthened. This paper takes the information transmission in the corona virus disease 2019 (COVID-19) in 2020 as the research object. The five types of media — central government media, vertical professional media, national market-oriented media, local government media, and local urban media are chosen to be studied. The micro-blog information released during the period was used for the descriptive analysis of word frequency radar. This paper uses the information space communication model to analyze the characteristics of information transmission from three perspectives: professional and non-professional media, power and non-power media, and different administrative levels. The analysis shows that when the government responds to information transmission in public health emergencies, the timeliness of the professional field of information transmission to the decision-making level, the content filtering of different levels of information transmission, and the loss of authority information transmission need to be strengthened. Therefore, it is necessary to increase the transmission of professional information, reduce the filtering of hierarchical information, enhance the release of authoritative information, and strengthen the construction of information management.
