The purpose of this study is to investigate the influence of two categories of sources of technology on subsidiary performance. These technology sources can be associated either with the internal Multinational Enterprise (MNE) system; or, the local environment in which the subsidiary is based. A questionnaire-based survey was carried out on 88 subsidiaries located in Greece and results were derived through the use of ordered probit analysis. Internal MNE technology sourcing has a positive impact on subsidiary performance, which is stronger than that of local (Greek) technology sourcing. Contrary to our expectations, technology sourcing linked to the local context primarily has a negative influence on subsidiary performance.
