随着新兴媒体迅速崛起，大众传媒的主导性被瓦解。传统电视媒体的话语权被旁落。如何在危机中寻找契机以扩大舆论话语空间成为了近几年来电视媒体的探索方向。扩大主流舆论空间是主流电视媒体与新兴媒体融合的重要目的。参与式文化所构建的全新的媒介文化图景要求传统媒体利用新的姿态与用户产生情感连结。作为优质内容的提供方，与成熟网络平台进行合作，具有互联网思维对主流话语进行传播是成本较小，见效较快的方法。而对于部分基础较好，资源较丰富的电视媒体，还需着力自建融媒体聚合平台，建构台网深度融合的生态矩阵，重塑舆论影响力。 With the rapid rise of new media, the dominance of mass media was dismantled. The voice of traditional TV media has been sidelined. How to find an opportunity to expand public opinion space in the crisis has become the direction of exploration for TV media in recent years. Expanding the mainstream public opinion space is an important objective of the integration of mainstream TV media and emerging media. The brand-new media cultural landscape built by participatory culture requires traditional media to adopt a new posture to create an emotional connection with users. As a provider of quality content, it is less costly and more effective to cooperate with mature online platforms and spread mainstream discourse with an Internet mindset. For some TV media with a good foundation and rich resources, they need to build their own integrated media aggregation platform, construct an ecological matrix for the deep integration of Taiwan and the Internet, and remodel their influence on public opinion.
