本研究以遷移至臺灣、中國、日本、南韓之929位商管領域學者為研究對象，針對國際遷移及國內遷移等兩種遷移類型學者，分別比較兩者在發表文章特性、合著特性與遷移情形上的差異。研究結果顯示，四國之國際與國內遷移者的論文生產力相近，論文影響力則以臺灣學者發表文章的平均被引次數最多，可知臺灣無論國際或國內遷移者，發表文章皆有一定水準。國際合作部分，研究發現臺灣、日本及南韓以美國為首要合作對象，中國則與香港合作較為緊密。遷移情形分析結果顯示，四國之國際遷移者的平均遷移率高於國內遷移者，平均每人遷移2次。綜合而言，本研究是少數以大量書目資料同時分析國際遷移與國內遷移，研究結果可用來觀察東亞國家整體的科學遷移表現。

This study examines differences in research performance, international collaboration, and migration moves between two types of migrant researchers: international and domestic migrant researchers. The investigation focuses on 929 researchers in the field of business and management in four East Asian countries-China, Japan, South Korea, and Taiwan- and explores their scientific output and movements across types of institutions. The study uses bibliographic data from the Web of Science and Scopus author ID to disambiguate information across databases. The findings reveal that both international and domestic migrants demonstrate comparable productivity. Concerning publication quality, international migrants exhibit a higher citation impact, and researchers from Taiwan demonstrate the highest average number of citations per paper among the four countries. For international collaboration, international migrants report a higher rate of international collaboration than domestic migrants. The United States serves as the primary collaborative partner for migrant researchers from Taiwan, Japan, and South Korea, whereas China has a closer partnership with Hong Kong. Finally, international migrants demonstrate a higher frequency of migration, with an average of two moves per capita. This study provides empirical evidence for the value of scientific migration from the perspectives of international and domestic migrants in East Asian countries.
