Abstract: Having an analysis on the impact of open source intelligence on the national intelligence work system, will simultaneously contribute to the abundance of the overall national security concept. The paper uses the method of systematic literature review, and analyzes the current content from four aspects: the characteristics of open source intelligence, open source intelligence technology，the current application field and the bottleneck restricting open source intelligence research, to construct a theoretical relationship diagram of the four national intelligence work system. Then it summarizes how the national intelligence work system should be improved to adapt to the development of open source intelligence better.Open source intelligence, which is mainly used in the fields of major epidemic prevention and control, think tanks, and national defense technology transfer, has the characteristics of open source and open analysis methods. However, there are still some deficiencies existing in personnel training and technology. The national intelligence work system should attach great importance to the top-level design and formulate rational criteria for the analysis method of dividing open source intelligence sources. To improve the flexibility and validity of the overall system, each department should combine its own characteristics to develop a system suitable for open source intelligence to play its own role, as a necessary supplement to the overall system. A "horizontal" and "vertical" talent training mechanism need to be established, and the connotation of the national intelligence work system need to be expanded. Above all, cross-field and compound talents with both intelligence analysis capabilities and information technology capabilities also need to be cultivated.

Key words: Open source intelligence, Overall national security view, Intelligence work system, Open source intelligence technology
