Taiwan Hakka discipline and Indigenous discipline are the higher education institutions and academic outputs constructed by the state through the promotion of multicultural policies. However, the issue of the politics of recognition on disciplinary establishment is still a developmental dilemma for them today . This paper compares the development process of the two disciplines, and puts forward the theory of "ethnicity and epistemic justice". The establishment of the Hakka discipline and Indigenous discipline is to provide the space for the collective interpretation of the epistemologies of ethnic minorities. That is to say, the knowledge will be radically transformed into the knowledge of empowerment and resistance of the weak . As a result, epistemic justice is to turn epistemological stratification into epistemological diversity. Only by constructing subjectivity of their own epistemologies can ethnic minorities construct subjectivity.
