Abstract:As an important indicator to measure the high-quality and sustainable development of tourism, tourism efficiency has received extensive attention from academia in recent years. Firstly, the multidimensional connotation of tourism efficiency was explained, and a conceptual analysis framework of tourism efficiency was constructed based on the three-dimensional economic-society-ecological dimension. On this basis, the research progress of tourism efficiency was systematically combed, and the existing tourism efficiency measurement methods and evaluation indicators were summarized and reviewed. The results are as follows. In terms of research topics, it has expanded from focusing on tourism economic efficiency to tourism social efficiency and tourism ecological efficiency. In terms of research content, existing research basically answers the question of "how much tourism efficiency is?" but there is still a lack of in-depth discussion on the formation process and influence mechanism of tourism efficiency. In terms of research methods, tourism efficiency measurement methods are becoming more sophisticated and complex. The revision and improvement of the traditional DEA model has become an innovative point of research in recent years. Finally, the research prospects are put forward from four aspects which are strengthening essential connotation research, in-depth discussion of influence mechanism, promotion of research method innovation, and emphasis on practical application of research results.
