International scientific mobility is the most important feature of the globalization of modern science. In the last few decades, the changes in technological conditions and contemporary culture have profoundly reshaped disciplinary development in various countries as well as the pattern of international mobility. With the help of large-scale datasets to capture longitudinal, country-level patterns of migrations in science, this paper outlines the evolution of scientific mobility over the past 100 years. There has been a dramatic growth in scientific mobility both at the global and regional levels. As one of the manifestations of multi-polarization in science, the disparity in the attractiveness of countries for scientists is decreasing, and this is partly attributable to stronger relations among higher- and lower-income countries in mobility networks. Another interesting finding was that scientists from high-income countries now have a lower probability of returning to their original countries than those from lower-income countries, unlike the trend that was observed in the 1990s. Additionally, we examined the factors that might affect the number of scientific immigrants, and highlighted the importance of social capital connections between countries and “pull” factors like economic and scientific strength of countries. This paper reviewed the dynamics of scientific mobility from different aspects and shed light on the studies of evolution of science.
