Bank’s Personnel Networks Through Interlocking Directorates of Members of the Supervisory Board on Such Top Management Organs of Other Enterprises After World War II: Analysis of Period After the Enactment of the 1965 Corporations Law

Based on results in Chap. 8 , this chapter considers the personnel networks of the three largest banks, including the second- and third-party companies, after World War II using social network analysis. This chapter also compares the network of each bank. Then, this chapter examines the conditions in the late 1960s, the period after the enactment of the 1965 Corporations Law, which regulated the limitation of the number of mandates one person may have on the supervisory board. The late 1960s were chosen because the basic system of interlocking directorates in postwar Germany was established during this time. This chapter analyzes the “cohesiveness” of the network of each bank and enterprise at a core position in the information flow and media of the network and industrial sector to which such an enterprise belonged. Through these discussions, the characteristics of each bank’s network are clarified.
