台灣的政論性「叩應」節目雖飽受批評，但仍有固定收視群。本研究運用政大選研中心2004年立委選舉調查資料，以區別分析的統計方法探究在選舉期間，看或不看政論性「叩應」節目的民眾，在社會背景、心理特質及傳播行爲等方面的差異，以了解接觸政論性「叩應」節目的行爲意涵。區別分析結果顯示，會看政論性「叩應」節目的民眾，具有教育程度與政治知識較高、政治興趣較強、以及較常接觸報紙、電視、雜誌、廣播及網路中選舉訊息等特徵。此一發現顯示，接觸政論性「叩應」節目可以說是政治參與的一項重要指標。
This study aims at analyzing the characteristics of the audience of Taiwan's political TV call-in programs. A discriminant analysis found that those who attended to political TV call-in programs in election seasons tended to be better educated with higher levels of political knowledge and political interest. In addition, compared to the non-viewers of political TV call-in programs, the viewers of the programs spent more time to acquire electoral information from newspapers, television news, magazines, radio, and internet web sites. This finding indicated that watching political TV call-in programs could be an important indicator of political participation in election seasons.
