Both the black sheep effect and the ingroup favoritism had been explained in terms of social identity theory, and had been associated with the scale of group identification. On the other side, the influence of studying abroad on identity had also been pointed out. This study is examined that (1) the relation between studying abroad and the scale of group identification; (2) effects of the studying abroad and the scale of group identification on opinion toward a person and a nation, to verify whether black sheep effect and ingroup favoritism occur to Chinese international students in Japan. Thirty-eight Chinese international students participated in this research. The research mainly revealed the followings: (1) the result of a Chi-Square Calculator showed that there is not a relationship between living abroad and the scale of group identification; however, (2) the result of ANOVA suggested that, for the people who study abroad longer, the black sheep effect and the ingroup favoritism probably did not appear, while the black sheep effect and the ingroup favoritism would occur on the people with higher group identification. So it can be concluded that the longer time for living abroad, the lower group identification probably.
