A Comparative Study on Social Media Use and Public Participation in Korea and the United States: Does Social Media Matter?

This study examines how the use of different types of social media, such as Facebook and Twitter, affects public participation, drawing on the theory of motivation, which addresses the effect of internal and external political efficacy as well as the perceived political importance of social media. The study also investigates the interaction effect between social media use and perceived the political importance of social media on public participation. Employing a comparative perspective on an issue that has not been well studied, the study further seeks to discover potential variations in the impacts of different social media on public participation in the United States and Korea, both of which held presidential elections at the end of 2012. This study conducted hierarchical multiple regression analyses using data collected from college students in the United States and Korea. It shows the positive impact of social media use and its interaction effect with the perceived political importance of social media on the offline and online public participation of youth. The political motivational factor is found to be critical to driving public participation. This study also shows that the impact of Facebook use is more influential than Twitter use on public participation in the United States, whereas the opposite pattern is observed in Korea.
