The Construction Path of National Identity of Ethnic Minority in Border Areas from the Perspective of Political System Theory: Based on the Derung Ethnic Group’s Two Millennium-Leap Development

Since the establishment of the People's Republic of China, the question of whether the heterogeneous border areas, adjacent to different countries, can achieve national integration and build a stable national identity in the border society is not only a challenge in national governance but also crucial for overall national security. The two “millennium leaps”of the Derung ethnic group provide a observable case for examining the construction path of national identity in minority nationality countries in border areas. From the perspective of political system theory, in terms of environment-input, the sources of national power, the recognition of national identity, and the original mission of the Communist Party of China collectively constitute the input of the political system. In terms of output: a series of policy measures related to order and development based on the “sense of gain”. In terms of feedback: the two-way interaction between the Derung ethnic group and the leaders of the Party and the state. In the process of development, the development of the Derung ethnic group and the development of the country are constantly adjusted and coupled, resonating at the same frequency, thus forming a strong national identity and political loyalty characterized by listening to the Party, feeling grateful to the Party, and following the Party.
