This paper analyzes the possibility and necessity of establishing Global Chinese Linguistics as an academic discipline. The possibility of this endeavor derives from two aspects. On the one hand, the scientifi c study of language phenomena in a specific field is conventionally named as linguistics preceded by a modifi er, e.g. Chinese linguistics as the study of Chinese language. Therefore, the study of global Chinese named as Global Chinese Linguistics would be a natural naming practice. On the other hand, the research in Global Chinese so far has built up a solid foundation for the framing of a new discipline. The necessity of establishing Global Chinese Linguistics mainly lies in the top layer planning of global Chinese language research. It is argued that the formulation of Global Chinese Linguistics will help to expand the research scope, strengthen the research capacity, and conduct in-depth relevant studies, which will in turn be conducive to the theoretical construction in this field.
