Digital cultural tourism has become the core driving force for promoting the high-quality development of rural food tourism in the new era, profoundly changing the supply side, demand side, and resource allocation pattern of rural food tourism. In the development practice of rural food tourism in Guizhou Province, in the face of the current situation and challenges, efforts should be made from three dimensions: big data cultural tourism, cloud computing cultural tourism, and Internet of Things cultural tourism. A new model for the development of rural food tourism with “big data, cloud computing, and Internet of Things” (referred to as “big cloud and Things”) as the core should be innovatively constructed. This will accelerate the digital transformation and upgrading process of rural food tourism.
