Abstract: The new communication technology has changed the flow structure of social information, while the polarization of public opinion is closely related to new media. Therefore, the public opinion response and information governance research under social media is important. This paper uses social network analysis to select the public opinion of "Shuanghuanglian Incident", which is representative during the epidemic. We analyze the network structure from three aspects of network density, centrality, and cohesive subgroups, then explore the behavior characteristics and performance of different node actors. According to the rights status of public opinion networks, this paper divides several types of media platforms, and the study finds that different types of media presents a differential order pattern in public opinion events . The influence of traditional media is enormous. First, the central media represented by CCTV in government media has played a leading role in public opinion. Then the overall performance of emerging media is poorly except "Toutiao".At last the role of "opinion leaders" is insignificant. Therefore, this article believes that under the guidance of the government, it should be gradually form a collaborative governance involving traditional media, government media, emerging media, and netizens.
