The literature on ownership structures has made continual use of notions such as cross-holdings and pyramids which are closely related to the vastly increasing network literature. We propose to transfer successfully applied network methods such as network graphs, the MAN-classification scheme, and centrality concepts to the corporate control and corporate governance branch as well. Given these concepts and a unique data set containing 2784 companies we can identify the most powerful German companies and their characteristics.
