Cultural tourism of ethnic minorities is not only an important driving force for economic development in ethnic areas，but also plays an important role in the development of China’s cultural and tourism industries. The study explores the status quo of cultural tourism of ethnic minorities，and analyzes the problems existing in cultural tourism of ethnic minorities by the niche theory. The ethnic cultural tourism of Yunnan Hani Terrace and Guizhou Thousand Households Miao Village were selected as case studies and discussions. Finally，based on building a super IP by the “intelligence and travel integration” background，the research puts forward the strategy of niche expansion of minority cultural tourism industry.
