Research in economic geography has recently been challenged to adopt more institutional and multiscalar perspectives on industrial path development. This article contributes to this debate by integrating insights from (evolutionary) economic geography as well as transition and innovation studies into a conceptual framework of how path creation in emerging industries depends on the availability of both knowledge and legitimacy. Unlike the extant literature, we argue here that not only the former but also the latter may substantially depend on nonlocal sources. Conceptually, we distinguish between multiscalar export, attraction, and absorption of legitimacy. Coupled with conventional knowledge indicators, this approach enables us to reconstruct how not only external knowledge sourcing but also multiscalar institutional dynamics contribute to a region or country’s ability to leverage its potential for path creation in an emerging industry. Methodologically, we develop legitimation indicators from a global media database, which was built around the case of modular water technologies. Cross-comparing the evidence from six key countries (India, Israel, Singapore, South Africa, the UK, the US) with differing path creation constellations for this emerging industry, allows us to hypothesize how multiscalar legitimation influences a country’s prospects for creating a radically new industrial path.
