本文摘要 本研究主要目的是以內容分析法分析台視在報導1996至2008年的四屆總統大選時，選舉新聞的政黨偏差現象，並進一步剖析台視民營化前後，所有權轉變對選舉新聞政黨偏差的影響。研究結果顯示，台視在民營化前的三屆（1996年、2000年、2004年）總統大選中，皆出現明顯政黨偏差，且偏差方向均對執政黨較為有利。但台視民營化後，選舉新聞的政黨偏差情形變得較不明顯，在2008 年的總統大選中，台視的選舉新聞已遠比以往公正。為瞭解所有權轉變對台視選舉新聞公正性的影響，本研究以深度訪談法專訪十名台視記者，分析四屆總統選舉時的採訪歷程。受訪者皆認為，台視在民營化前，政府及執政黨明顯影響選舉新聞報導；但民營化後，政府及執政黨的影響力降低，台視選舉新聞已較為公正。

Abstract This study examines how Taiwan Television Enterprise reported the campaign and candidates during the 1996, 2000, 2004, and 2008 presidential elections in Taiwan. A content analysis of evening election news of the television company indicated that there were significant quantity bias, source bias, and presentation bias in its coverage of the first three presidential election campaigns. However, the television company was more balanced in its coverage of the 2008 presidential campaign. An in-depth interview of 10 reporters of the television company indicated that ownership structure has direct or indirect influence on election coverage of the television company. The change of ownership of the television company in 2007 has contributed to the achievement of more balanced media coverage in the 2008 presidential election.
