媒介無所不在已改變了現今人們生活與致知的本質，國際新興傳播理論「媒介化」（mediatization）正從歐陸向外湧動，以嶄新的視野探看媒介化世界。本文爬梳近年陸續提出之媒介化理論概念，首先述明媒介化概念如何朝向側重社會建構過程；其次說明傳播形定、深媒介化與閱聽人化的概念流變；繼而以「#MeToo」為案例帶入跨媒介敘事之閱聽人參與交互討論，最後試以詮釋媒介化如何引借敘事觀點互相證成於新舊交融之深媒介化環境下的意義建構過程。

The omnipresence of new media has changed the nature of people’s lives and their means of acquiring knowledge. Mediatization theory has emerged from the European continent as a means of exploring the social world. The researcher constructed a dialogue with the aforementioned conceptual framework of mediatization theory published internationally in recent years and borrowed certain perspectives from the narrative communication research. First, this study examined the concept of mediatization and its role in social construction. Second, it explained the conceptualization of communicative figurations, deep mediatization, and audiencization. Finally, the study analyzed the #MeToo movement in a Taiwanese context to interpret the transformation of audiences during narrative participation in transmedia storytelling through “narrative worldmaking” in the age of deep mediatization.
