Spatiotemporal mobility network of global scientists, 1970–2020. Liu, T., Pei, T., Fang, Z., Wu, M., Liu, X., Yan, X., Song, C., Jiang, J., Jiang, L., & Chen, J.

Paper doi abstract bibtex The mobility of scientists, manifested by movements to new academic institutions, grows with globalization and plays a crucial role in individual careers, institutional productivity, and knowledge dissemination. Current research on scientists’ mobility focuses on aggregated levels such as inter-country mobility, with little attention paid to fine-grained institutional level, leading to a simplified spatial portrayal of the mobility. To fill the gap, we take scientists in geography as examples, and reconstructed their dynamic mobility network among institutions from 1970 to 2020 based on massive literature metadata. Our findings reveal the spatial mobility pattern that is now dominated by North America, Western and Northern Europe, East Asia, and Oceania, with the trend of intensification, multipolarity, and inequality over time. Specifically, the mobility network exhibits clear community structure largely constrained by spatial proximity and national borders. We also uncovered a universal downward mobility pattern embedded in the hierarchical structure. Our quantitative analysis further suggest that mobility is facilitated by multiple realities, including spatial, cultural, and scientific proximity, institutional rankings and national economic levels, cooperation, and visa-free policies, with varying dynamics. These results contribute to spatiotemporal insights into the mechanisms of scientific development in theory, and the basis for talent policymaking in practice. • The mobility of scientists has long been dominated by institutions in developed countries, with China emerging in recent decades. • Spatial proximity and national borders largely constrain the mobility of scientists. • The hierarchy in mobility network determines the decrease trend in institutional prestige from original to new academic positions. • The mobility of scientists between institutions is positively associated with stronger cooperation, same language, and visa-free policies.
