Abstracts

PL
Celem artykułu jest zbadanie sieci finansowych powiązań kapitałowych i krzyżowych pomiędzy firmami notowanymi na giełdzie w Polsce (WIG20 i mWIG40) oraz analiza zmian, które zaszły w strukturze własnościowej banków w wyniku pandemii COVID-19. Przegląd literatury pozwala na wyszczególnienie czterech głównych typów sieci finansowych: powiązań krzyżowych, korelacji, długu oraz przyczynowości Grangera. Skonstruowane zostały cztery kierunkowe sieci finansowe powiązań kapitałowych. Dwa kluczowe mierniki zastosowane w niniejszym badaniu to PageRank (ekspozycja na ryzyko i znaczenie sieciowe) oraz modularność (wykrywanie społeczności).

This article aimed to examine the financial networks of equity linkages and cross-shareholdings between publicly listed companies in Poland (WIG20 and mWIG40) and to explore the changes that occurred in bank ownership because of the COVID-19 pandemic. The literature review revealed four main types of financial networks: cross-shareholding, correlation, debt, and Granger-causality. Four equity-based directed financial networks were constructed. The two key network measures used in this research are PageRank (risk exposure and network importance) and modularity class (community detection).
