“卡脖子” 技术概念辨析-内生性矛盾、国家主体与外部限制的共同建构

The issue of neck - jamming technology is crucial to the development of science and technology, however, there are many conceptual ambiguities in the understanding of neck - jamming technology. This paper clarifies the concept of neck - jamming technology, which is conducive to clearing the root cause and promoting the solution. First, the endogenous contradiction between the old model and the new stage is the root cause, and the political behavior of the technology supply side to launch technology restriction on the technology demand side is the external fuse. Second, under the premise that the neck - jamming technology is state - based, this paper analyzes the definition and characteristics of neck - jamming technology. In order to avoid the waste of resources caused by the generalization of the concept, the scope of neck - jamming technology is further clarified. Finally, disruptive technology and countermeasures are discussed, and the role of neck - jamming technology in supporting high - level scientific and technological self - reliance and self - improvement is proposed.
