Abstract

We propose institutional mobility indicators based on researchers’ mobility flows in 22 major fields of science across 1,130 Leiden Ranking institutions from 64 countries. We base our indicators on data from the Dimensions database and Global Research Identifier Database. We use researchers’ first and last affiliations to estimate the extent authors have moved across institutions as well as countries. For each institution, we quantify the shares of researchers with the same affiliation (insiders), those who came from another institution within the country (domestic outsiders), and those coming from a different country (foreign outsiders). Institutions in Central, Eastern, and Southern Europe have the highest share of insiders, whereas institutions in Northern America and Western and Northern Europe have a higher share of foreign outsiders. Foreign outsiders are most common in small and wealthy countries. No disciplinary differences are observed, as captured by the field classification scheme of Dimensions.

研究人员的机构流动性：学术近亲繁殖和国际化的文献计量证据

摘要

我们根据来自 64 个国家的 1,130 个莱顿排名机构的研究人员在 22 个主要科学领域的流动性提出机构流动性指标。我们的指标基于维度数据库和全球研究标识符数据库的数据。我们使用研究人员的第一个和最后一个隶属关系来估计作者跨机构和国家移动的程度。对于每个机构，我们量化了具有相同隶属关系的研究人员（内部人员）、来自国内其他机构的研究人员（国内外部人员）和来自不同国家的研究人员（外国外部人员）的份额）。中欧、东欧和南欧的机构内部人员比例最高，而北美、西欧和北欧的机构外部人员比例更高。外国外来者在富裕的小国最为常见。正如Dimensions 的字段分类方案所捕获的那样，没有观察到学科差异。
