Data ownership is the fundamental prerequisite for data circulation and utilization. According to the basic principles of data characteristics and data processing activities, a series of behaviors and activities of information and data can be divided into the production behavior of data entities, the processing behavior of information value entities, and data governance. According to the Hohfeld rights analysis theory and the subject's power theory of object utilization, rights boundaries can be created for the holding, utilization, and sharing of data. On the basis of distinguishing behaviors such as data production, data processing, and data governance, data can be accurately confirmed between different entities such as providers, collectors, storage providers, and information processors, distributors, and users. The implementation of the relevant system requires improving the rules of data governance, as well as formulating and improving corresponding standards and procedures. At the same time, enterprises should also carry out management innovation in multiple dimensions to adapt to the multifaceted requirements of the digital age and anticipate structural challenges in the development of the digital society.
