I analyze how high-skilled immigration affects native, immigrant and collaborative innovation, using an IV approach that exploits exogenous variation in push factors of migration across origin regions and over time. The overall impact of high-skilled immigration on innovation is positive and substantial. High-skilled immigrants from developed regions of the world and with a PhD contribute by innovating themselves, enhancing native-immigrant and international collaborations, and spurring native innovation. I show that the latter effect is likely driven by the access to immigrants’ origin specific knowledge. In contrast, while there is no evidence for a significant direct contribution of high-skilled immigrants from less developed regions and without a PhD to innovation, they contribute indirectly, by stimulating native innovation.

谁和谁？解开高技能移民对创新的影响

我分析了高技能移民如何影响本土、移民和协作创新，使用一种 IV 方法，该方法利用跨起源地区和随着时间的迁移推动因素的外生变化。高技能移民对创新的总体影响是积极而巨大的。来自世界发达地区并拥有博士学位的高技能移民通过自我创新、加强本土移民和国际合作以及刺激本土创新做出贡献。我表明，后一种效应可能是由获得移民的起源特定知识所驱动的。相比之下，虽然没有证据表明来自欠发达地区且没有博士学位的高技能移民对创新做出了重大直接贡献，但他们通过刺激本土创新间接做出了贡献。
