6. Discussion
6.1. Contributions In the context of China, our findings confirm the widely held belief that emigration enhances exports, especially for more differentiated goods (Rauch & Trindade, 2002). Our departure from and thereby main contribution to the literature concerns a key aspect of network heterogeneity, that is, the skill structure of migrants. Viewing immigrants as trade-creating entrepreneurs enables us to conceptually re-consolidate the two mechanisms underpinning the migration-trade nexus. Our entrepreneurship perspective is focused on aspirations, that is, what motivates immigrants to become international entrepreneurs who help create demand and subsequently deliver on such demand. Our novel hypothesis and empirical support, including illustrations from our fieldwork, serve as a context-bound test of such entrepreneurial aspiration logic, and will have implications for research in two primary ways.
