At present, the construction of a scientific and comprehensive theoretical system for the Chinese nation commonality has advanced from the theory of the chinese nation commonality to a new stage of chinese national community studies. As a strategically important emerging interdisciplinary discipline, Chinese national community studies aligns with China’s strategic need to continuously shape national certainty through the great unity of the Chinese nation. Its foundational concepts encompass three core categories: the substantive Chinese nation, the holistic Chinese nation commonality and the identificatory awareness of the Chinese nation commonality. These concepts integrate China’s strength through pluralistic unity, its values through the five shared elements and its spirit through the four coexistences. The formation and development of Chinese national community studies rest on rich theoretical foundations: the Sinicization and modernization of Marxist community thought and ethnic theories; the synthesis and unification of the Chinese civilization perspective and historical view of the Chinese nation; the summarization and sublimation of the CPC’s ethnic work theories and practices; the resource provision and interdisciplinary innovation from Chinese philosophy and social sciences. The disciplinary construction goal for Chinese national community studies is positioned as evolving from an interdisciplinary pilot to a primary discipline within interdisciplinary studies. Its development should adhere to the principle of integrating political orientation, academic rigor and practical relevance. Following the intrinsic logic of foundation-history-practice-comparison, its secondary disciplines or research directions could encompass four dimensions: theory of the Chinese nation commonality, history of the Chinese nation commonality, practical construction of the Chinese nation commonality and the Chinese nation commonality in the contemporary world. Advancing the disciplinary system of Chinese national community studies further requires complementary academic, discursive and talent cultivation systems.
