Directorship interlocks in Singapore: A social network analysis

Abstract

This paper uses social network analysis to examine the extent of interlocking directorships across companies listed on the Singapore Stock Exchange Limited (SGX) Mainboard in 2004. Detailed analyses on different industry sectors within SGX as well as an overall analysis of all the companies on the SGX Mainboard were performed. The findings show that there were varying degrees of interlocking directorships within the different sectors, and on average, each director from a SGX Mainboard-listed company sits on more than 2 directorship positions.
