Does ICT Promote the Private Provision of Local Public Goods?

In this paper, we found three conditions to clarify the social network structure for local people solving local problems with social network analysis. One is that a core group exists in the community; the second is that the inside of the core group is an exclusive network; and the third is that a person who has high value of Betweenness centrality is next to the core group. And we showed that using ICT increases the density of the social network in our case.
