Currently, key strategic materials of China are partly subject to control by other countries, facing the dilemma of "choking". Domestic substitution of key strategic materials is in urgent need of further breakthrough. This paper systematically analyzes the present situation and existing problems of domestic substitution in the field of key strategic materials. Further, the breakthrough points of key strategic materials domestic substitution are discussed by analyzing the process and industrial characteristics. On this basis, the bottleneck problems faced by key strategic materials domestic substitution at the present stage and the key capabilities that need to be built urgently are analyzed. Finally, based on the common innovation experience of material powers such as the United States, the European Union and Japan, strategic measures and policy suggestions are put forward from the perspective of technological innovation systems to promote domestic substitution of key strategic materials.
