摘要

全球流动发明家(GMIs)是指在职业生涯中跨国流动的发明家,在过去二十年里,他们的人数增加了十倍以上,流动的通道也转向了新兴市场,新兴市场的存在日益增多。我们发现,在流动前已在某一技术领域获得专利的全球发明家,在到达目的地后成为该技术领域的先驱发明家的可能性要高出 70%,我们将此解释为知识跨界扩散的证据。回国者通常是指在美国和其他发达经济体待过一段时间后回国的新兴市场发明者,他们回国后申请开创性专利的可能性是移民到国外时的两倍。最后,我们发现,在目的地技术生命周期的早期阶段,全球创新中心在发明人网络中的地位越重要,当地发明人吸收特定技术知识的速度就越快。

Global Mobile Inventors

The number of Global Mobile Inventors (GMIs), inventors moving across borders during their career, has increased more than tenfold over the past two decades, and the corridors of mobility have shifted towards a growing presence of emerging markets. We document that GMIs that have patented in a given technology before moving are 70% more likely to be among the pioneering inventors in that technology once they arrive at destination, which we interpret as evidence of knowledge diffusion across borders. Returnees, which are typically inventors from emerging markets that go back after having spent some time in the US and other advanced economies, are twice as likely to file pioneering patents once returned than migrants when arriving abroad. Finally, we find that the more central the GMIs in the network of inventors during the early stages of the technology life-cycle at destination, the faster the technology-specific knowledge is absorbed by local inventors.
