Reflecting on the evolving organisation of multinational enterprises (MNEs) and their growing presence in international business, this book focuses on value creation by subsidiaries in transition economies, and uses Poland as an example. Drawing on internalisation and business network theory, the author analyses the role of the subsidiary with the aim of explaining the mechanisms of subsidiary functional specialisation and its operationalisation. The book presents an innovative model illustrating the determinants of the functional responsibilities of subsidiaries, whilst providing an empirical analysis of foreign subsidiaries in Poland. Addressing a vital topic in international business and management studies, this Palgrave Pivot will be useful for researchers, students and practitioners.
