铸牢中华民族共同体意识已成为新时代民族工作的主线。民族旅游因流动性、文化性与经济性兼具，为各民族交往交流交融提供了持续的内生动力。本文从旅游本质、时空特征、多维影响、主客互动与文化基因五方面系统梳理民族旅游强化共同体意识的动力要素。研究发现，这些要素并非彼此孤立，而是通过“空间流动—经济共融—文化互鉴—社会共建—情感共鸣”的链式反应，层层递进、相互强化。据此，文章提出“动力输入—过程融合—认同输出”框架，并给出深化文旅融合、优化主客互动、细化利益共享与政策保障等提升路径，以放大民族旅游的凝聚效应，为中华民族共同体建设提供学理支撑与实践指引。

Consolidating the sense of community for the Chinese nation has become the central task of ethnic work in the new era. Ethnic tourism, characterized by mobility, cultural richness, and economic benefits, provides continuous endogenous impetus for interactions, exchanges, and integration among different ethnic groups. This paper systematically examines the driving factors of ethnic tourism in strengthening the sense of community from five aspects: the essence of tourism, spatiotemporal features, multidimensional impacts, host–guest interaction, and cultural genes. The study finds that these factors are not isolated but mutually reinforcing through a chain reaction of “spatial mobility — economic integration — cultural mutual learning — social co-construction — emotional resonance”, progressing step by step. Based on this, the paper proposes a framework of “dynamic input — process integration — identity output” and suggests enhancement pathways such as deepening cultural–tourism integration, optimizing host–guest interaction, refining benefit-sharing mechanisms, and improving policy support, so as to amplify the cohesive effect of ethnic tourism and provide theoretical support and practical guidance for the construction of the Chinese national community.
