The disciplinary attribute constitutes the foundation development and the fundamental basis for its continuity and evolution. The historical trajectory of special pedagogy, the innovative progression of its theoretical framework, and the deepening of its practical domains collectively delineate its intrinsic process of disciplinary intersection. By assimilating, synthesizing, and integrating theories, methodologies, and advancements from multiple disciplines, it has established its academic legitimacy and secured sustainable developmental momentum. Disciplinary intersection serves not only as the primary impetus for its genesis and growth, but also pioneers new directions for fulfilling the fundamental mission of fostering virtue and cultivating talent, advancing equitable and high-quality educational development, achieving national objectives of addressing disparities and empowering the vulnerable, and promoting holistic educational goals. To further deepen disciplinary intersection and propel the high-quality development of special pedagogy in China, this study proposes pathways focusing on spectrum-based problem domains, convergent research paradigms, innovative autonomous knowledge systems, heterogeneous professional team construction, and open disciplinary platform development.
