Within the framework of the project (carried out within the consortium of the Warsaw School of Economics (SGH) and Poznań University of Economics (UEP)), an original model explaining selected determinants of the innovation-related position of FSs in the MNE network was developed and tested on a sample of 440 FSs established in Poland. The following determinants of FSs’ innovation performance were included in the study: the innovation capacity of the FS host economy, the innovative potential of FSs, FSs’ linkages to the actors within the MNE internal network, as well as the relations of FSs with external partners in the host country. These factors directly or indirectly affect subsidiaries’ positions within the MNE system.
