Abstract:In recent years, with the basic and strategic role of new infrastructure in the economic and social development is increasingly prominent, its connotation from the initial 5G, the Internet of Things, and others gradually expanded to three types of infrastructure including information, integration, and innovation. Innovation infrastructure is the supporting platform for the development of information technology and technological progress, and it is also the driving force for the continuous evolution of new infrastructure forms and the continuous expansion of functions, and the inclusion of innovation infrastructure in the scope of new infrastructure construction reflects the full trust and eager expectation of China for scientific and technological innovation. It is of great significance to clarify the connotation and relationship of the three types of new infrastructure, to recognize the challenges faced by the current development of innovation infrastructure, and to lay out innovation infrastructure efficiently during the 14th Five-Year Plan to improve the quality and efficiency of supply of new infrastructure.
