Abstract: Taking the data of 13 prefecture-level cities in the "Beijing-Tianjin-Hebei" region from 2007 to 2021 as the object of research, the coupling and coordination relationship between digital technology and the high-quality development of the tourism industry was analyzed quantitatively, and the spatial effect of digital technology on the high-quality development of the tourism industry and its mechanism with the help of the spatial Durbin model was explored.The study found that: there is a significant spatial and temporal correlation between digital technology and the high-quality development of tourism in the "Beijing-Tianjin-Hebei" region, in which Beijing plays a leading role in the development of tourism in the neighbouring cities, and the tourism industry shows the phenomenon of geospatial agglomeration; Digital technology has an "inverted U-shaped" impact on the high-quality development of local tourism, and a "U-shaped" impact on the high-quality development of tourism in neighbouring regions.These findings remain robust after the robustness test and provide new theoretical perspectives and empirical support for how digital technology can effectively empower tourism.
