Along with the arrival of the digital era, promoting the high-quality development of rural tourism with a digital economy has become a new driving force and goal. This study examines the mechanism of digital technology to promote the high-quality development of rural tourism based on the perspective of stakeholders in rural tourism development. After selecting the evaluation indexes of digital technology to promote the high-quality development of rural tourism, the weights of the indexes are determined, and the level of digital technology to promote the high-quality development of rural tourism is measured by using the fuzzy comprehensive evaluation method in a rural tourism site as an example. The driving force factors of digital technology to promote the high-quality development of rural tourism are selected from both internal and external dimensions, and the driving force of digital technology to promote the high-quality development of rural tourism is analyzed by using geographic detectors for divergence and factor detection and interaction detection. The results can be obtained that the overall development of the sample rural tourism sites is located between average and better, with a comprehensive score of 6.842, especially in its cultural digitization and environmental monitoring digitization, with scores greater than 6. Digital technology to promote the high-quality development of rural tourism is subject to the joint effect of a variety of factors. The number of Internet broadband access ports is the core factor, and the factor contribution rates are all above 0.8. The research on effects and driving forces in this paper is of great significance in achieving high-quality development of rural tourism.
