Data property rights are of great significance in the data foundational institution system.Data property rights are structurally separated into three rights, namely, the right of data resource possessing, the right of data processing and the right of data product managing.Existing theories are not practice-oriented, and the responsive way of right-granting can hardly fix the market failures as well.Based on the data factor circulation practice, two typical logics of data factor circulation were proposed, namely, architecture logic and market logic.Based on market logic, the data factor circulation value chain model was constructed.The generated way of right-granting could provide an explanation of the structural separation of data property rights.

At present, the theory and practice of authorized data operation are still chaotic and controversial.Based on the clarification of what open data means in the Chinese context, the current theory that authorized data operation is either complementary to open data or part of open data was challenged, and authorized data operation that implemented open data through a market-oriented delegation mechanism was repositioned.The need was presented to unpack the definitions of two key elements of authorized data operation: data product and data operation, and a novel interpretation of authorized data operation was proposed as it was a social-technical system serving the purpose of open data and mainly producing primary data products for reuse rather than just using with support from a rich tiered data operation service ecosystem.

Based on the conceptual and historical analysis of data and production factors, it was proposed that the data factor was the computer data and its derivative that was gathered, sorted and processed according to specific production needs and participated in social production and operation activities.It should focus on the value of data factor as a new driving force for economic growth and production development.It was summarized the three value release ways of data factor, namely, business operation by data, intelligent analysis by data and external effects by data exchange, and it should be given full attention in the process of promoting the development of data factor.

Data products are the implementation path of "data resources for external transactions" in the accounting classification.Research on the development and circulation of data products can lay the foundation for accounting treatment related to enterprise data resources.Through case analysis, the development and circulation process of data products of bank A were investigated and summarized, and the process from development to external provision of data products was extracted.It was found that as data product development was often based on the data and data capabilities accumulated in the past, the cost calculation of a single data product often faced significant difficulties.In addition, the unit of development and circulation of data products was often based on the application scenarios of data resources, and the value of data products dependedon their application in the scenarios.Therefore, the collection, processing, and sharing of data for data product transactions could play a significant role in the accounting treatment of data resources.

Data trust is regarded as a new and credible data transaction model.Data trust is not only an organizational structure to guarantee information security, but also an innovative institutional design to enhance the trustworthiness of data factor market.A data trust operation mechanism was designed, and the organizational structure, characteristics, functions, and regulatory scheme of the data trust under this mechanism were discussed.That data trust contained two independent legal relationships were pointed out.Its most important feature was the risk segregation among participants, which was the basis of data trust as a credible data transaction model.Data trusts could play an important function in the data value chain, specifically in terms of data value addition, data escrow, and data commons.Finally, the unique advantages of data trust based on the institutional guidelines of “20 measures to build basic systems for data” were demonstrated, and that personal data trust and public data trust were feasible practical paths was pointd out.
