英文摘要:
      In the field of science communication,social media have played an increasingly important role in communicating controversies. A three-layer analysis framework including the subject,contents and strategies was set up to explore the media framing of Genetically Modified (GM) food,one of the most controversial issues so far,in the world’s largest video-sharing site YouTube. The most viewed 20 videos are selected as research samples. Based on an analysis of these sample videos,this study tries to describe the performances of the four players government, science community, business sector and nongovernmental organizations in the process of media framing. The study explored seven categories/seventeen sub-fields,and summarized three main framing strategies. Advices based on conclusions drew from this study are provided for the future related research.
