EVALUATION AND EARLY WARNING OF GOVERNMENT NEW MEDIA INFORMATION DISSEMINATION EFFECTIVENESS IN PUBLIC EMERGENCIES
Keywords:
Government communication, Digital governance, Public opinion, Early warningAbstract
This study focuses on evaluating and early warning the effectiveness of information dissemination by government new media during public emergencies. Based on a literature review, it defines the concept of dissemination effectiveness and constructs a four-dimensional analytical framework, including timeliness, content quality, interactive responsiveness, and communication guidance. An evaluation index system is developed to measure performance across different stages using normalized data, and a composite index is further constructed for dynamic early warning analysis. The results show significant stage-based differences and fluctuations in dissemination effectiveness. In the initial stage, timeliness is the main strength, while interaction and guidance are relatively weak. As events evolve, content quality, responsiveness, and guidance improve, and the composite index exhibits a pattern of initial decline followed by recovery. Early warning analysis indicates that major risks stem from insufficient follow-up updates, limited explanatory capacity, delayed responses, and low sensitivity to public opinion changes. This study provides theoretical and practical insights for optimizing government information release and improving emergency communication systems.References
