Abstract： Under the background of digitalization and intelligent manufacturing, the establishment of a data sovereignty exchange platform that protects data sovereignty and meets the needs of Big Data sovereign exchange has become an important driving force for the development of the digital economy. The concepts of data sovereignty and data sovereign exchange are summarized, and the practical experience of international data space and GAIA-X program are introduced to provide reference for the development of data sovereign exchange platform in China. By analyzing the platform mode and technical points of the Smart Factory Web platform and the Internet of Things data sovereign exchange platform, the scheme and development ideas of China′s data sovereign exchange platform are discussed. Relying on the international data space reference framework, a credible and interoperable data sovereign exchange platform reference architecture is proposed.
