In this master thesis, the knowledge exploitation factors in multinational enterprises are studied. Hereby, the researchers analyse the perspective of subsidiary middle managers to understand their influence on knowledge exploitation and to understand the factors that influence middle managers in subsidiaries to share their knowledge. The aim is to provide practical implications for multinational enterprises on how to enhance knowledge exploitation from the subsidiaries and to contribute to the existing theory on knowledge exploitation factors in the light of middle managers. Thereby, the chosen qualitative research approach is abductive grounded theory, including interviews with middle managers from mostly European subsidiaries of multinational enterprises. The findings present which factors impact middle managers to share knowledge with the headquarters. Additionally, influencing factors of middle managers on knowledge exploitation are described. Hereby, the master thesis shows the interdependency between multiple factors of knowledge exploitation, resulting in a model to provide an overview. Furthermore, implications to the theory and practical implications are given on how multinational enterprises can enhance knowledge exploitation within the organisation.
