Abstract: Under the background of the new round of industrial transformation to the in-depth evolution, the construction of key core technology breakthrough capabilities is of great significance for improving China′s scientific and technological research system and achieving independent and controllable industrial development. This paper drew inspiration from the CBP concept in the military field to construct a "three-capabilities" model with the core dimensions of collaborative integration and agglomeration capabilities, innovation investment and transformation capabilities, and innovation resource support capabilities. It explored the construction needs of key core technology breakthrough capabilities and the interaction mechanism between the "three-capabilities". On this basis, a capacity building evaluation index system for key core technology breakthroughs was established, and the entropy weight - grey correlation projection matrix model was used to calculate the capacity demand construction status of key core technology breakthroughs in China′s IC industry from 2009 to 2020. The feasibility and effectiveness of the index system were empirically tested and the results indicated that the level of capability demand construction for breakthroughs in key core technologies in China′s IC industry is fluctuating and increasing, and the innovation investment and transformation capacity are showing an upward trend in 2019 and 2020. However, it is still necessary to strengthen the capability to collaborate, integrate, gather, and ensure innovation resources. This paper will provide practical inspiration for the capacity building needs of key core technology breakthroughs.
