Abstract：Based on the review of existing literature,the concept of key core technology is redefined according to the principle of “specific concept plus differential”,clearly pointing out its special attributes that include being designed and constructed by a specific subject,playing a key role in the industrial technology system on which it is based and occupying the central position,and aiming to obtain the dominance of industrial value allocation by scarcity and exclusivity.The four characteristics of key core technologies are reconsidered from the perspective of technology origin,with emphasis on the complexity of the system structure and the originality of research and development activities with it as the “root technology”.The key core technologies are derived from the information age in which the global industrial specialization division of labor.In this context,data platform or “data-driven”technology become a constraint to the development and breakthrough of key core technologies in important industries.A “two-stage”breakthrough strategy in the form of national major science and technology special projects is proposed.The breakthrough of key core technologies is divided into four levels and their respective constraints and reasonable paths are demonstrated.
