The main contribution is to provide deeper insight into the causal relationships between subcontractors’ relational capabilities and their degree of internationalization, mediated by the level of subcontractors’ involvement with local firms and the networks linked to international markets. While confirming the existence of a strong connection between subcontractors’ relational capabilities and the level of subcontractors’ involvement with local hubs of international networks, it was found that subcontractors’ dependence on multinational enterprises could hamper their expansion into foreign markets. More specifically, the study offers only partial support for the so-called ‘springboard’ effect, i.e. the role exerted by local hubs of internationalized supply networks in projecting small subcontractors abroad.
