Abstract: The construction of new infrastructure represented by 5g technology has been accelerated, covering important industries such as communication, finance, energy and transportation, and infiltrating all aspects of social life. In the process of accelerating the construction of 5g network, the security problem of 5g supply chain has become increasingly prominent. It is analyzed carefully that the characteristics of 5g supply chain security and 5g supply chain security risk in this paper, the 5g supply chain security asset identification, threat identification and vulnerability identification is compared with the general ICT supply chain security risk, and the Countermeasures of 5g supply chain security risk in China is put forward, so as to further promote the development of 5g in China and Strengthen 5g suppliers and demanders to provide reference for strengthening their own supply chain security capacity-building.
