Abstract

This research analyzes the board network of the companies in Iran’s capital market from 2019 to 2022. The research results indicate that despite the difference in the level of communication, most units are related to each other. However, some units are in a better position to establish this relationship. Even in the communication network, there is a gap between the positions of the units and the difference between them becomes considerable, creating a class structure. The better position of some units has caused them to encounter fewer mediators in gaining access to other units, to have faster access, and to have a higher ability to gain access to information through the cluster of network members. In addition, some units are on the communication path of other units, so they have a power of influence. Since these units are in the flow path of information, they have more accessible and faster access to information. These units can play the role of key actors in the governing structure.
