Additive Manufacturing and Production Internationalization: An Internalization Perspective

Additive manufacturing (AM) has been touted as a transformative technology that alters the way production is organized across geographical and organizational boundaries, yet little is known what this means for firms' internationalization of production. In this paper, we take an internalization theory perspective to hypothesize how the adoption of AM technology influences a firm's propensity to have an international production subsidiary, the number of foreign production subsidiaries that it operates, and the number of countries in which it has foreign production subsidiaries. To test our hypotheses, we rely on European Patent Office data to identify firms with AM-related patents and match this information to firm-level data of international production subsidiary networks from Bureau Van Dijk. Using both propensity score matching and zero-inflated negative binomial regressions, we find that AM firms are more likely to have a foreign production subsidiary than non-AM firms and operate them in more countries. We find partial evidence that AM firms have more foreign production subsidiaries than non-AM firms, in particular as compared to comparable innovative firms.
