The modernization process and multicultural exchanges have impacted traditional multi-ethnic villages，making it worthwhile to systematically explore the construction of home community in the new era from both theoretical and practical perspectives.Under the theoretical context of community in sociology and anthropology，this paper analyzes the limitations of village community in multi-ethnic traditional villages.Taking Village X in Yunnan as an empirical case study，this paper examines its evolution characteristics across three periods：before market reform，during market reform and during the period of ecological civilization construction.Before market reform，a stable community was formed in Village X. During market reform，tourism intervention brought rapid development but also led to issues such as uneven distribution of benefits and a weakening of cultural characteristics emerged，rusulting in community degradation.During the period of ecological civilization construction，a mutually beneficial community has gradually emerged，focusing on fair distribution of benefits and cultural inheritance.Based on empirical analysis，the concept of home community is defined from three dimensions：community interests，cultural integration and emotional value.The study comprehensively considers aspects such as multi-dimensional dynamic changes，sustainable development and adaptability principles，prominent policies and community participation to elucidate its connotation.It innovatively constructs a framework for the home community，enriches the theoretical system of the Chinese national community and proposes strategies for optimizing the ethnic home environment，revitalizing ethnic cultural development，and enhancing awareness of home protection.
