The residents' perceived importance of various types information and satisfaction of local government related information disclosure during the epidemic period are investigated through designed questionnaire. Later, the evolution trend of the overall residents' information demand is identified by CIPA analysis method, and the reasons for the trend changes of key information categories are analyzed. [Findings/Conclusion] Compared with the epidemic information demand on social platforms, the type of information demand of residents in the outbreak areas is more abundant and stronger, and this feature does not change significantly along with the evolution of the epidemic in different regions. The information importance is increasing firstly then decreasing overall with the regional evolution because of information overload and other issues, but the satisfaction on all kinds of epidemic information is on a certain rise. The significantly evolved information is concentrated in "life and material information", the importance and satisfaction of information need both gradually increas, and finally reach the area in the first-quadrant: "continues to maintain".[Originality/Value] Compared with the broad data in social platforms, this paper focuses on the real information needs of local residents in the epidemic area, which reflects the potential trend of residents' information demand,is more valuable for the decision-making of the local government. Furthermore, the introduction of temporal attributes based on the CIPA method extends the applicability of the analysis method.
