User Engagement in Public Discourse on Genetically Modified Organisms: The Role of Opinion Leaders on Social Media

This study adopted a quantitative content analysis to examine how source attributes of opinion leaders and their message framing influenced user engagement in the public discourse of genetically modified organism (GMO) on Chinese social media.
