Abstract
The development of social capital in an online community was investigated by creating survey data of online game players. The results showed that the frequency of collective communication, the homogeneity of members, and the openness of the online community had positive effects on trust, while the size of community and community hierarchy had negative effects. This shows that participation in online communities can create social capital. Furthermore, the results showed that online social capital influences real-life behavior. For example, reciprocity online facilitated offline social participation, even after controlling for offline social capital and other real-life determinants. These results demonstrate the positive contribution of collective online communication to a democratic social system.
