Can social media increase government responsiveness? A case study of Seoul, Korea

Despite the expectation that social media use in the public sector contributes to enhancing government responsiveness to citizens, few empirical studies exist on whether social media use actually leads to more responsive public administration in practice and how social media are used by governments to build citizen-centric governance. The purpose of this study is to examine what roles are played by mayors and public officials in social media networks to increase government responsiveness. Thus, we adopt social network analysis (SNA) to the Twitter network of public services as well as carry out a case study on interactions among the mayor, local government, and citizens via Twitter in Seoul, Korea. The research findings show that the mayor of Seoul plays the most important role as a bridging hub in the Twitter network. Specifically, the mayor serves as a bridge between different clusters of citizens and public officials as well as a hub for the most connected users in the network. The mayor's role as a bridging hub in the Twitter network contributes to enhancing government responsiveness by making possible to overcome the disconnection between citizens and the local government, and information asymmetry among the mayor, public officials, and citizens.
