Abstract: With the in-depth promotion of China's rural revitalization strategy in ethnic areas, lodging industry, as an emerging industry integrating ethnic culture, tourism and rural revitalization, has shown strong economic growth potential and cultural heritage value. However, in the current development of B&B industry in ethnic areas, there are problems such as a single participant, insufficient integration with other related industries, and imperfect industrial chain, constraining the space for the development of B&B industry. These dilemmas can be broken through from expanding social participation and strengthening cross-border cooperation, attracting more social forces to participate in the B&B industry, establishing the benefit linkage mechanism among the government, enterprises, communities and other social organizations, strengthening the B&B branding and marketing, and making full use of cross-border synergy between the B&B industry and the fields of rural tourism, cultural and creative industries, and the preservation of national culture, so as to unleash the huge influence of the B&B industry on economic growth and cultural inheritance of the ethnic areas. Then, the huge potential of B&B industry to the economic growth and cultural inheritance of ethnic areas released is to provide a theoretical basis and practical path for the implementation of the strategy of rural revitalization in ethnic areas in China.

Key words: folk lodging industry, rural revitalization, social participation, cross-border cooperation
