The figures below display networks of relations between different fields of business research at public German universities. They visualize how the fields are connected to each other, which fields are stronger embedded and which are peripheral.
Altogether, 1.287 full professors are currently teaching and studying business at 78 institutions. I took their membership in scientific commissions at the German Association for Business Research (VHB) and, in case of no membership, information about their institutes or chairs to specify the fields of research. Each scholar may be affiliated to one or more of the following communities: 1) Banking and Finance, 2) Business Taxation, 3) Academic and Higher Education Management, 4) International Management, 5) Logistics, 6) Marketing, 7) Sustainability Management, 8) Public Business Administration, 9) Operations Research, 10) Organization, 11) Human Resources Management, 12) Production Management, 13) Accounting, 14) Technology, Innovation and Entrepreneurship, 15) Business Information Systems, 16) Philosophy of Science and Business Ethics.
The sixteen fields of business research are shown as nodes. The size of a node depends on the number of members in the respective commission. A tie between two nodes indicates a professor’s membership in both communities. Tie strength indicates the number of professors with co-memberships (the stronger the tie, the more co-memberships). The second network displays only ties with more than 10 co-memberships. It’s an arbitrary threshold to provide better visual interpretation.
The biggest community is Accounting (243 members), followed by Organization (229), and Marketing (200). The smallest fields are Academic and Higher Education Management (50) and Public Business Administration (77). It’s obvious that a functional focus is more common than object-oriented specializations. The strongest links exist between Organization and Human Resource Management (96 co-memberships), Production Management and Logistics (65), and Accounting and Business Taxation (61). The most embedded field of reserach is Organization, followed by Production Management. Surprisingly, the two object-oriented fields of Academic and Higher Education Management and Public Business Administration are at the periphery of the network, despite the fact that their operations likely involve most of the other functional areas.
