本研究運用台灣社會變遷調查資料針對社交媒體的政治性使用行為與公民參與作觀察。研究發現社交媒體的政治性使用行為對於社區參與的關連並不大，卻和政治參與行為具有顯著正向關連。進一步的分析則發現不同的社交媒體政治性使用行為能預測不同型態的公民參與。社交媒體搜尋政治相關訊息行為對於個體政治參與行為有顯著預測力。政治性發文的行為則能顯著預測意見表達。加入社交媒體的政治社群可以正向預測如造勢或遊行等集體參與行為。研究也發現使用者越常透過社交媒體訊息參與政治活動，則越會參與所有的政治參與行為。

The present study employed the “Taiwan Social Change Survey ( TSCS)” data collected in 2014 to examine the relationship between political use of social media and civic engagement. The results show that there was a weak relationship between political use of social media and community civic engagement. However, the political use of social media was positively related to three dimensions of political civic engagement. Informational use of social media could significantly predict individual form of political civic engagement. Joining political group or fan club on social media could significantly predict collective form of political civic engagement. Commenting on information related to politics on social media could significantly predict offline political expression. Implications and recommendations for future research are also discussed.
