Abstract:

Cross-border ethnic groups,living across borders within the national territory yet outside the administrative center,are a special subject in national border administration.In the national construction of citizenship for these cross-border ethnic groups by means of political measures,cultural psychology and civic culture,the backward society,weak link between culture and psychology,and lack of modern political civilization in the border areas often lead to the mismatch between the political and legal citizenship of these cross-border ethnic groups and their legitimate rights,causing problems in their identity choice and national identity.Therefore,the national administration in the border areas should be based on the correct match between the political and legal citizenship of the cross-border ethnic groups and their factual citizenship.

Key words: citizenship, cross-border ethnic groups, administration in the border area, national identity, Yunnan Province
