In this paper, the super efficiency SBM model based on non-expected output is combined with Malmquist index to measure the tourism ecological efficiency of ethnic areas for more than 2004-2016 years, and it is found that the tourism ecological efficiency of the ethnic areas in the 2004-2015 ① with the change of scale efficiency, In 2016, the influence of pure technical efficiency was obvious, and the tourism ecological efficiency of ② ethnic areas showed the opposite sex, and the total factor productivity and production technology progress increased with each other, except Xinjiang and Tibet, other regions were on the rise, and the innovation and progress of ③ technology was crucial to the improvement of total factor productivity. Scale efficiency will restrain total factor productivity, and the improvement of comprehensive technical efficiency and pure technology efficiency depends on technological improvements. The level of economic development, the degree of opening up, the level of informatization, the regional industrial structure and the ecological efficiency of tourism in ④ region are positively correlated, while the traffic conditions, the development level of service industry and There is a negative correlation between environmental protection measures and tourism ecological efficiency.
