Abstract: The authorized operation system of public data has become an important part of leading the circulation of public data and unleashing the vitality of the digital economy. The pricing of public data products under the authorized operation system has attracted widespread attention from society. Taking practical needs as the starting point, this paper establishes a two-level pricing model for public data products from the perspective of the entire lifecycle of public data operation for the first time, based on the two-level development model of public data. According to the cost-premium method of value evaluation, public data product prices are divided into two parts: the premium for authorized usage fee for primary development and the premium for technical service fee for secondary development. At the same time, the value evaluation of public data resources is included in the price formation mechanism, and a public data resource value evaluation system is constructed based on the Analytic Hierarchy Process and Fuzzy Comprehensive Evaluation Method (AHP-FCEM). The practical process of the two-level pricing model is demonstrated through a specific example. Finally, corresponding policy recommendations are proposed following the two-level pricing model and value evaluation system.
