This study aimed to investigate the relationships among the online political participation of Facebook users from the perspective of social capital. We use the example of the controversial issue of the merger and acquisition of the Want Want China Times Group to determine whether social media use could have a positive function in enhancing the political participation of individuals. The results of an online survey conducted across Taiwan (N = 613) showed significantly positive relationships among Facebook use, life satisfaction, and political participation. Moreover, political interest, political knowledge, and friendship over Facebook all positively predicted political participation, suggesting that online social networks may be a solution for the disengagement of youth from civic duty and democracy.
