[Purpose/significance] In the era of intelligence, the decision-making function of intelligence services is becoming more and more important in national security, and the research on national security intelligence services is of great significance at the national strategic level and in the field of information science research. [Method/process]This study proposes a national security scenario-based intelligence service model centered on scenarios. This study aims to utilize security data to perceive the demand-side scenarios for intelligence services, which in turn guide the construction of supply-side resources for intelligence services. Based on the matching of supply and demand, service solutions are generated to achieve scenario-based intelligence service responses. [Result/conclusion] By establishing a theoretical framework for a data fusion-driven national security scenario-based intelligence service model, we aim to
respond to the objective requirements of the national security strategy at the macro level, while providing innovative in⁃tegration paths for national security scenario-based intelligence services at the micro level.
