In the dual context of the deepening development of globalization and the high-quality promotion of ethnic work in China's new era, the coexistence and prosperity of diverse cultures has become a distinctive feature of the development of ethnic regions. Ethnic exchanges, communication, and integration are the core path to strengthen the sense of community of the Chinese nation, and their high-quality development has important theoretical and practical significance. This article is based on the basic national conditions of a unified multi-ethnic country in China, and adopts a combination of literature research and case analysis to systematically sort out the current development status of ethnic communication, exchange, and integration, and analyze the practical difficulties faced by cultural homogenization, regional development imbalance, and inadequate long-term mechanisms; Sort out and refine three typical practice models: cultural leadership, industrial linkage, and public service empowerment, construct a collaborative operation mechanism of "organizational collaboration, cultural mutual learning, guarantee incentives, and feedback optimization", and verify the feasibility of the models and mechanisms through case studies of multi-ethnic settlements in Southwest China; Finally, targeted optimization paths are proposed from four dimensions: practical mode, mechanism system, core challenges, and guarantee support. Research has shown that a practical model that accurately adapts to regional characteristics and a sound collaborative mechanism are key to promoting the deepening development of ethnic communication, exchange, and integration. The research results can provide theoretical support and practical reference for the practice of ethnic communication, exchange, and integration in the new era, and to strengthen the sense of community of the Chinese nation.
