Abstract:
 The theoretical framework for the circulation of publishing data assets consists of the foundation layer, support layer, key layer, institutional layer, and value layer. Among these, the definition of the ownership of publishing data elements is a prerequisite for the circulation of publishing data assets, while the classification and grading of publishing data serve as the basic condition for such circulation. The methods for evaluating publishing data assets include the cost approach, income approach, market approach, and emerging digital intelligence technology-based evaluation methods. The traditional transaction methods of publishing data assets comprise purchase, exchange, auction, and intermediary transaction models, which mostly rely on pricing mechanisms such as market pricing, negotiated pricing, or cost-plus pricing. In contrast, the financial model of publishing data assets is an innovative model. Models such as publishing data asset pledge financing, publishing data asset securitization, and publishing data asset insurance provide new perspectives and ideas for the circulation and value realization of publishing data assets.
