Abstract: As a new manufacturing paradigm,the characteristics of complex manufacturing system and key core technologies of intelligent manufacturing,such as long period,high barriers,originality and frontier,put forward higher requirements for the “synergy” of the domestic substitution of key core technologies in intelligent manufacturing.In view of this,this paper puts forward the concept of “synergistic substitution” which is different from the traditional “competitive substitution”.The “synergistic substitution” is based on the system theory,which emphasizes that through creative integration of different technical elements or systems,the system coupling effect and super-added value effect of complex technical systems can be brought into play,and the overall technological leap of industrial chain can be promoted by synergistic innovation of complex technical systems to break the foreign single-point technology blockade.The “synergistic substitution” does not exclude the “competitive substitution” which is the norm in the local technical field of free competition.However,in the complex technical system such as intelligent manufacturing under the background of international competition with numerous technological barriers,the domestic substitution of key core technologies must rely on the synergistic substitution of the mutual coupling of sub-technical systems,and the key for synergistic substitution to achieve technological catch-up is the high-order coupling between subsystems rather than the inefficient cycle and backwards compatibility within the system.To effectively promote collaborative substitution,it is necessary to reshape the innovation incentive system and industrial chain governance mechanism with collaborative innovation thinking,to consolidate the underlying work of synergistic innovation within the technological systems of intelligent manufacturing,to build a specialization and cooperation system based on the integration of the industrial chain,to seek high-level coupling opportunities for key core technology innovation through high-level opening up,and to innovate talent motivation mechanisms effectively ensuring the implementation of national technology strategies.
