A Study of Social Network of Fund Managers Based on Centrality-Cohesive Subgroup Analysis
Using graph theory,centrality analysis,and cohesive subgroup analysis,de-constructing the social networks of fund managers into alumni relationship networks and colleague relationship networks,measures and analyzes the individual,partial,and whole network of Chinese securities investment fund managers from three different perspectives of gender,education,and region.The results show that:1)The overall size of male fund managers'social network is significantly larger than that of female ones,and the network breadth and structural complexity of the former far exceed those of the latter,while the latter has more isolated individuals than the former;2)The core subgroups of Shanghai and Beijing fund managers'social network revolve around core individuals with high degree centrality,but the core individuals in Shenzhen fund managers'social network are mostly"intermediaries"among subgroups;3)The overall structure of the social network of China's securities investment fund managers is complex,with a high degree of network complexity between groups and tightness of ties between individuals,and a spindle-shaped distribution of fund managers'centrality with a low number of extreme individuals.
