This paper sets out from Taiwan and China’s overseas students’ numbers, countries and majors, and is aimed at the return situation and the contribution of overseas return students for further study and comparison. The research is of the opinion that because the rise of China and the reformed opening-up, the Chinese Government even places more importance on studying abroad students. Similarly, those students are even more patriotic feeling and sense of missions for their motherland. So they hope in the future they are able to return home after graduation to contribute what they had studied. Because of this, the China studying abroad students and overseas return students are increasing every year. In recent years, because Taiwan Institutes for enrollments have a substantial increase; thus, the number of Taiwan studying abroad students is far less than the number of China studying abroad students. Taking the international advanced technology, culture and management knowledge and experience back to their countries is the largest contribution to the study of education. Therefore, in the face of Taiwan students to choose to stay at home study, in fact, it will have a negative impact on Taiwan’s international competitiveness in the future. The research shows that if the number of Taiwanese studying abroad remains in the doldrums, then, the cultivation of international talents of Taiwan might occurred the fault.
