Cross-Cutting Discussion on Social Media and Online Political Participation: A Cross-National Examination of Information Seeking and Social Accountability Explanations

摘要

The question of whether cross-cutting discussion engenders or depresses political participation has offered mixed findings in the literature. Following recommendations from a meta-analysis, this study tests two competing arguments: the information seeking explanation for engendering participation and the social accountability explanation for attenuating participation. Probability surveys were conducted among young adults in Taiwan, Hong Kong, and China, and analyses examined the relationship between cross-cutting discussion on social media and online political participation. For the Taiwan and Hong Kong samples, political information seeking positively mediated the relationship, but desire to avoid social conflict also attenuated the relationship. Neither mechanism was significant for the China sample. The findings suggest that the competing explanations are not mutually exclusive, and they highlight the importance of examining the variety of contingent conditions that influence the relationship between cross-cutting discussion and political participation in different national contexts.
