In the era of big data,data rights confirmation has become an important strength to promote data circulation and market development,ensure data revenue,and achieve data security.Based on complex information environment and from the perspective of data value chain,this paper explores the mechanism of data rights confirmation.Based on the previous research results of value chain and data value chain,this study constructs a value chain model involving the development of the whole life cycle of data,such as data acquisition,data processing,data analysis,and data application.Then,with reference to the"Effect-Mechanism-Analyzing-Mechanism"(EMAM)management research methodology,the data right confirmation mechanism was constructed,and a variety of subjects,objects and rights bundles involved in data right confirmation were sorted out,so as to provide a reference for the establishment of the basic system of data rights confirmation.Finally,relevant recommendations were put forward,including the establishment of a classification and grading standard system,safeguarding the security of data rights trading,improving the data rights system,optimising the ecology of the data factor market,innovating data rights management tools,and deepening the application of blockchain and other technologies.
