The three stages, basic logic, and future prospects of the research on national economic security since 1990

National economic security is essential for a nation's survival and development. The accelerating evolution of deglobalization imposes new demands on research in this area. This paper systematically reviews the evolution of research hotspots, research trajectories, and research frameworks in the field of national economic security, both domestically and internationally, using a combination of qualitative and quantitative methods based on the CNKI and WOS databases, and puts forward future prospects. Research since 1990 can be divided into three stages. The research hotspots at different stages and in different countries show national and stage differences, but are closely linked to economic globalization, national games, and emergencies. Based on the "pressure-state-response" framework, this paper summarizes the main lines, basic logic, and evolutionary paths of national economic security research under the interaction of threats and security. The collaborative evolution of threat and security sub-fields achieves horizontal expansion and presents national and stage differences. In security assessment, differing perceptions and perspectives on national economic security lead scholars to vary in their selection of assessment methodologies, indicators, and the construction of indicator systems. Synthesizing existing literature, this paper summarizes the "3+5" security guarantee system framework of security guarantee measures, points out the national and stage differences in guarantee measures, and generates "spillover" effects. Finally, based on the linkage of multiple risks, the game of multiple subjects, the interdisciplinary research framework, and the construction of national economic security theory, future prospects are put forward.
