This paper analyzes the determining factors of South to Center-North migration flows in Italy for five different educational groups. We find strong support for the paramount role of total and education-specific migration networks. Furthermore, we unveil an inverse relationship between the magnitude of the response of migration flows by educational level and the regional endowment of human capital. More generally, it emerges that once migrants educational attainment is explicitly considered, the reaction of migration flows is highly heterogeneous with respect to the push and pull factors that usually determine them. In the economics of migration literature, these results have not yet been documented.

受教育程度的移民流动：解开推拉因素的异质作用

本文分析了意大利五个不同教育群体的南向中北移民流动的决定因素。我们发现总体和特定于教育的移民网络的重要作用得到了强有力的支持。此外，我们揭示了不同教育水平的移民流动响应幅度与区域人力资本禀赋之间的反比关系。更普遍的是，一旦明确考虑移民的教育程度，移民流动的反应就通常决定它们的推拉因素而言是高度异质的。在移民经济学文献中，这些结果尚未记录。
