Abstract: 【Purpose/significance】In the process of promoting the construction of a cultural power and public cultural service system in the new era, it is necessary to study the application of relevant metaverse technologies in digital libraries.【Method/process】In re⁃ sponse to the main challenges faced by the construction and service of digital libraries in China, as well as the new demands brought about by technological upgrades, an in-depth analysis was conducted from three aspects: resource construction, user service mode in⁃ novation, and management and operation mechanism innovation. Based on the metaverse technology system, a digital library operation framework was constructed.【Result/conclusion】It can effectively solve the main problems faced by current digital libraries, such as inconsistent standards, multiple copyright disputes, and insufficient technical application capabilities. At the same time, it can im⁃ prove resource development capabilities, collection efficiency, and user service levels.【Innovation/limitation】Gradually clarify the technical route and business system of digital library construction, and steadily promote the transformation and upgrading of digital li⁃ braries in China.
