This article investigates the taken-for-granted notion of scientific mobility as fundamentally “global.” We use self- reported biographical profile data of over a hundred thousand scientists from ORCID (Open Researcher and Contributor ID) who received a Ph.D. between the 1980s and 2010s. These data are advantageous over data commonly used to trace scientific mobility like surveys and disambiguated bibliometric data, as ORCID data offer both publication histories and a curriculum vitae itemization of scientists’ education and employment. We find that scientists who do move internationally in their careers increasingly move within the same transnational region. Furthermore, while we find that mobility between countries has remained stagnant since the 1980s as compared to mobility within countries, scientists who move internationally do so more frequently but for shorter distances. European and Asian Ph.D. holders comprise the majority of scientists who are driving these trends.

本文研究了被认为是基本“全球”的科学流动性的概念。我们使用来自ORCID（开放研究人员和贡献者ID）的十万多位获得博士学位的科学家的自我报告的传记资料。在1980年代和2010年代之间。这些数据优于通常用于追踪科学流动性的数据（例如调查和歧义的文献计量数据），因为ORCID数据既提供了出版历史，又提供了科学家教育和就业的履历表。我们发现，在自己的职业生涯中真正走向国际的科学家越来越多地在同一跨国区域内迁移。此外，虽然我们发现自1980年代以来，与国家内部的流动相比，国家之间的流动一直处于停滞状态，进行国际移动的科学家这样做的频率更高，但距离更短。欧洲和亚洲博士学位 持有者是推动这些趋势的大多数科学家。
