Research on the Generation Mechanism of Audiences’ Oppositional Interpretation of Short Video of Government Affairs in Emergent Public Health Events

: Index theory points out that the government will "power index" the media, and the media will rely on government sources for news reports. The audiences will choose to trust the government's news based on media reports. But in the new media environment, short videos are emerging one after another. Everyone is a shooter, and the role of the media is greatly weakened. In the public health emergencies, the audiences' oppositional interpretation of the short video of government affairs appeared. So, does this mean that the index has failed? On the basis of reviewing the literature, the hypothesis of the influencing factors of the oppositional interpretation of the short video of government affairs audiences is put forward. Through the data collection and analysis, it is obtained that the age is significantly negatively related to the audiences' oppositional interpretation of the short video of government affairs in public health emergencies. Party members of the Communist Party of China are not prone to oppositional interpretation. The rapidity and accuracy of the communicator dimension, perceived usefulness, perceived interest, and perceived intelligibility of the audience dimension are significantly negatively related to the oppositional interpretation of the audiences.The secondary transmission of the media helps to reduce the audiences' oppositional interpretation of the short video of government affairs in public health emergencies. Finally, we discuss the the generation mechanism of audiences' oppositional interpretation of short video of government affairs in emergent public health events and whether the index is failed , and believe that the index theory is still applicable in the new media environment.
