Differences among Social Network Structures in the Private Sector, Politics and NGOs in Croatia

The paper describes and interprets differences among social network structures in the private sector, politics (local administration) and non-governmental organisations (NGO) in Croatia. Social network analysis (SNA) methodology was used to examine networks in three sectors, which were found to differ in terms of centrality measures and substructures. In the private sector network, centrality values of network members were related to their respective positions in the organisational hierarchy. In the politics network, centrality measures values of members were influenced both by hierarchy and by the number of same-party members. In the NGO network, all members had high centrality values. Substructure sizes were low in the private sector and high in the NGO sector; in the politics network, they were dependent on the number of same-party members.
