It is of practical significance to explore the intelligent transformation of public digital cultural services based on 5G and other high-tech for promoting high-quality service development. Therefore, this paper firstly combs the process of intelligent transformation in relevant fields, supplements the definition of intelligent transformation of public digital cultural services, and believes that transformation needs to be carried out from four core elements: resources, services, space, and management; Secondly, combined with the functions of high-tech technologies such as 5G, it is expounded that the driving role of 5G in the transformation is embodied in resource integration, service personalization, intelligent space, intelligent management; Finally, it is proposed that the intelligent transformation practice of public digital cultural services driven by 5G should be carried out through such paths as strengthening key technologies research, promoting the integration of industry and service chains, establishing a standard specification system, cultivating composite talents, and strengthening the joint cooperation of multiple forces.
