Abstract: ［Purpose/Significance］Scientific researchers have become an important talent element in the era of knowledge-driven economy, and their international mobility is crucial to talent strategies for all countries. Analysis on gender differences in their mobility could help better understand the mobility model and improve the talent introduction mechanism. ［Design/Methodology］This study proposed three hypotheses based on the analysis on moving frequency, returning tendency and moving time. Then, we obtained resumes from the ORCID website and analyzed the working experiences of 26,315 scientific researchers who had international mobility until 2017.［Findings/Conclusion］Firstly, there is a significant gender difference in the frequency of mobility as female scientific researchers have less mobility frequency than their male counterparts; the corresponding personnel ratio decreases while the mobility frequency increases; there is no significant gender difference between male and female in the rate of returning to the home countries. Secondly, British males and Spanish females are most inclined to return to their home countries. Thirdly, both male and female scientific researchers have more mobility in their early career stages whereas no significant gender difference has been found in the choice of mobility time.［Originality/Value］This study reveals the difference in mobility tendencies of male and female researchers, which lays a good foundation for further study of the differences and their essence in various contexts, as well as seeking solutions for the disparities.
