本研究從政治、科技與兩岸關係的面向，分析《中國時報》、《聯合報》與《自由時報》，揭露它們報導與評論傳播「政策」（2016-2022）的異同，探索其原因，特別提示它們未能再現的部分。納入分析的「政策」議題有七：文策院與國際影音平台的創設、OTT與愛奇藝（不）納管、公視董事改選、新聞議價法，以及數位中介服務法。三報都支持創設文策院與新聞議價法，在另五項政策議題中，三報對「兩岸關係」從而對朝野政黨的「政治立場」，影響其呈現最稱明顯，然而媒體個別企業本身的利益會在必要之時發揮重要性。媒體呈現七項傳播「政策」議題時，「政治」面主要談及政府的作為與不作為，「科技」面多討論立法方向與草案條文，「兩岸關係」面隨三報的立場差異而生。最常消失在報端的議題，是相關政策必然涉及的經費高低及其來源的討論或建言，報界或影視界的困境也因黨政立場的差異而遭淹沒或淡化。

Focusing on the China Times, the United Daily News and the Liberty Times, this thesis analyses their reports and commentaries on communication 'policies', discusses the 'policies' from politics, technology, and cross-strait relations aspect, between 2016 and 2022. Differences of their coverage are explored, reasons giving rise to their divergences are investigated, and significant policy issues not represented in the media are emphasised. Seven 'policies' as presented in the media are carefully scrutinised. They are 'setting up Taiwan Creative Content Agency and TaiwanPlus', re-electing PTS's board of governors, (not) regulating OTT and iQiYi, enacting 'News Bargaining Act' and 'Digital Intermediary Service Act'. All three dailies endorse setting up 'Taiwan Creative Content Agency' and enacting 'News Bargaining Act'. For the other five 'policies', the media's perspectives on 'cross-strait relations' and correspondingly their political affiliations cast significant impacts upon how these policies were covered, though media's respective interest normally has its say in related representation. It's further discovered that 'politics-oriented' items mostly touch upon what government has or has not done, 'technology-oriented' items are mainly on law-makers' ideas and legal texts proper, and 'cross-strait relations' items necessarily reflect the dailies' perspectives. What is missing in all three dailies are resources needed for fulfilling promises of policies concerned, and in the meantime, practical constraints the press and the audio-visual industry have been suffering is as well not attended.
