To address the challenges of insufficient integration between digital technology and tourism cultural industries, slow development of emerging business models, and delayed industrialization in Jiangxi Province, this study employs synergetic theory, establishes a coupling coordination evaluation model, and applies panel data analysis methods to investigate the coupling relationships, influencing factors, and operational mechanisms during the integration process. The research analyzes the coupling status, temporal and spatial distribution characteristics, and key constraints of these two subsystems in Jiangxi Province, while providing actionable recommendations for fostering new business models. These insights aim to accelerate the development of Jiangxi’s “Digital + Cultural Tourism” industry, promote innovative industrial forms, and enhance overall industrialization progress.
