舆论引导依然是媒介评论的重要功能。社交媒体影响与日俱增,带来了传统媒体评论舆论引导孤掌难鸣,娱乐化、消遣化倾向瓦解媒介评论严肃性,情绪化、非理性倾向促使消极舆论增多,社交媒体舆论倒逼主流舆论等一系列挑战。本文认为社交媒体环境下的媒介评论舆论引导,应从坚持用事实说话、善用新媒体、坚守专业主义立场、整合民意四个方面进行变革与创新。 Media guidance is still an important function of media commentary. The increasing influence of social media brings about a series of challenges, such as the traditional media commentary leading the solitude, entertaining and recreational tendencies to dismantle the seriousness of media commentary, the tendency of emotionality and irrationality, the increase of negative public opinion, and the media consensus of social media. This paper argues that the guidance of media commentary in social media environment should be changed and persisted from four aspects: adherence to facts, making good use of new media, sticking to professionalism and integrating public opinion.
