This paper investigates the impact of social media on political participation in the United States. Using survey data from a nationally representative sample, we examine the relationship between social media use and three forms of political participation: offline political participation, online political participation, and political discussion. We find that social media use is positively associated with political participation, both online and offline. Moreover, we find that social media users are more likely to engage in political discussion with their friends and family than non-users. These results suggest that social media can be an important tool for fostering political engagement and discussion.

摘要：

本论文调查了社交媒体对美国政治参与的影响。利用来自全国代表性样本的调查数据，我们研究了社交媒体使用与三种形式的政治参与之间的关系：离线政治参与、在线政治参与和政治讨论。我们发现，社交媒体使用与政治参与，无论是在线还是离线，都呈正相关。此外，我们还发现，社交媒体用户比非用户更有可能与朋友和家人进行政治讨论。这些结果表明，社交媒体可以成为促进政治参与和讨论的重要工具。
