Abstract: As the fundamental unit of the cultural digitization strategy, exploring the interactive evolution and driving factors between the digital economy and all-for-one tourism development at the county level is of great significance in enhancing the effectiveness of cultural dissemination and realizing new forms of tourism in county areas. This article constructs an evaluation index system for all-for-one tourism and the digital economy and uses the network centrality model to measure the spatial characteristics of the digital economy. Through the coupling coordination degree model and cold spot-hot spot analysis, an empirical study is conducted on the spatiotemporal evolution characteristics of the coupling and coordinated development between the levels of all-for-one tourism development and the digital economy in Fujian Province from 2015 to 2022. Additionally, the geographic detector model is employed to diagnose the key influencing factors of the coupling level. The research indicates that: 1) The overall levels of rural all-for-one tourism and the digital economy network in Fujian Province show a fluctuating upward trend, with the coupling coordination degree between rural all-for-one tourism and the digital economy demonstrating a spatiotemporal evolution pattern where a central growth pole radiates towards peripheral regions. 2) The global Moran's I increased from 0.421 to 0.453, with an increase in the number of both cold spot and hot spot areas, indicating an overall trend of 'spatial polarization'. 3) Economic factors and cultural education are the primary driving factors for spatial differentiation, and the results of factor interaction detection show both dual-factor enhancement and nonlinear enhancement.
