Abstract: A data product is an electronified non-material product that can be replicated and transferred with almost zero cost,this feature poses a challenge to the design of the production system of data product.At present,data products reach consumers mainly through supporting platforms.At the same time,critical issues such as the final shape,authorization mechanism and corres-ponding pricing methods of data products have not been effectively addressed.In this paper,based on the shareability and easy to copy of data product,it is concluded that the nature of data product circulation is a series of authorization process.Therefore,data product pricing is a form of authorization pricing.This article proposes principles of data product authorization and its pricing mechanism,a two-step authorization pattern of data product circulation,as well as corresponding structure of data product operation platform.

Key words: Big data, Data product, Digital economy, Two-step authorization
