Research on signal perception system of key technology regulation in the United States

The purpose of the study is to analyze the operation mechanism of the key technology control signal perception system, and reveal the deep logic and basic procedures of the United States’ external technical containment. Through literature review and information mining, this study analyzes the structural features of the U.S. key technology control signal perception system, such as “front-end technical perception and technology locking”, “mid-end technical evaluation and risk identification”, and “back-end technical control response and dynamic sanctions”. It further explores the participating subjects and role positioning of the United States in key technology control signal perception, the sources and mechanisms of intelligence perception of weak signals, the models and methods of technical assessment, as well as the means of technical sanctions. The research on the U.S. key technology control signal perception system provides a reference for China to deal with the risks of the technology decoupling led by the United States and build an independent and controllable technology governance system.
