This paper studies the international expansion of local subsidiaries of multinational enterprises (MNEs). The main questions asked are why and how MNEs' local subsidiaries in developing economies undertake international expansion. Drawing from the global value chain (GVC) perspective, I argue that local subsidiaries that were initially established to undertake production activities for export-oriented industries do not want to remain at the lowest-value-added position forever. They therefore undertake initiatives to get out of that position. The literature on initiative-taking subsidiary has predominantly focused on them becoming centers of excellence via R&D and innovation in the host country. I propose a different route of local subsidiary upgrading via foreign direct investment in more advanced countries. This strategy helps not only to gain internal prominence within the MNE network, but also to improve its external position within the GVC vis-à-vis the lead firms. The paper uses an in-depth case study of a Thai subsidiary of a Taiwanese electronic MNE to explore the transformation of the subsidiary from simply manufacturing for exports to becoming a strategic international expansion arm for the parent MNE. © 2013 Elsevier Inc.
