Data capitalization method and system based on data element value chain deconstruction

The invention belongs to the technical field of data capitalization and data circulation, and provides a data capitalization method and system based on data element value chain deconstruction, and the technical scheme is as follows: a data element value chain is deconstructed into an RPI closed-loop iteration model containing data resources, data products and data information; data resources are obtained, and a data product and data information are obtained in combination with an RPI closed loop iteration model; performing right confirmation and empowerment on the data resources, the data products, the data information and related transaction subjects; on the basis of right confirmation and right assignment, aiming at different data elements, adopting corresponding value assessment methods to carry out value assessment to obtain corresponding value assessment results; and in combination with a value evaluation result, forming three types of data assets of resources, products and information, generating a data
