The studies on FS innovation performance in transition economies, that cover the issue of FS innovation cooperation, are being undertaken only recently. There is still a cognitive gap in the knowledge on the relations between factors affecting FS performance and subsequent position within the MNE network from the perspective of FS established in transition economies. Therefore, this study intends to fill this gap. The formulation of the study concept has been based i.a. on resource-based view of a firm and its further extensions and on the network model of the MNE, and re-lated concept of firm’s embeddedness. Extended literature studies enabled the identification of significant factors that determine the position of FS within the MNE network (with focus on FS’s inno-vation performance on its position). Afterwards, an original conceptual model and research hypotheses have been developed for the analysis of the relations between factors that determine FS in-novation performance and affect its position. The conceptual model will be tested based on FS-level data collected with application of a survey based on questionnaire prepared for this study. The results of the quantitative analysis will be supplemented by the qualitative research with the use of case study method.
