This paper examines a largely unexplored channel of the effects of offshore production on onshore (domestic) innovation performance. We combine a comprehensive dataset mapping the global operations of Japanese multinational firms with patent statistics to measure innovation. The study finds that increased offshore production have little effects on onshore innovation performance once properly correcting a simultaneity bias. Furthermore, we find some weak evidence of increased offshore production downgrades the quality of innovation, measured by citations. Consistent with other studies, we find that an increase in overseas R&D is the main driver of innovation creation for multinational firms.
