Absztrakt:

Tanulmányomban a hálózatkutatás eszköztárával tárom fel a Budapesti Értéktőzsdén a 2020-ban kibocsátóként jelen lévő entitások tulajdonviszonyainak hálózatát, statikus módszerek, valamint exponential random graph modeling (ERGM) elemzés alapján. A hálózat pillanatkép-tipológiája és szimuláció alapú megragadása során nem pusztán a tőzsdén jelen levő kibocsátók közötti kapcsolathálózat kerül elemzésre, hanem a hálózathoz kapcsolódó, ám a tőzsdén nem jegyzett cégek tulajdonviszonyai is, így a tanulmány teljes egészében kezeli az értéktőzsdéhez kapcsolódó tulajdonosi hálózatot. A kutatás eredményeként pontos válasszal rendelkezünk a hálózat morfológiai tulajdonságáról, a centralitást meghatározó hálózati faktorokról, a hálózat hierarchiájáról, valamint a szimulációk segítségével a hálózat kialakulásáról. A tanulmány hozzásegíthet ahhoz, hogy tisztább képet kapjunk a tőzsdén jegyzett cégek kapcsolódási pontjairól, klasztereiről, amelyek későbbi longitudinális elemzésekhez adhatnak támpontot.
