构建数据主权的概念体系和模型，不仅有助于推动我国数据主权的实践应用，还有助于向国际输出我国数据主权的自主话语体系。文章运用文本分析法和内容分析法，解构数据主权的概念内涵并提炼认知维度，在此基础上厘清概念间关系，最终构建概念体系并将其模型化。从认知维度可以推导出数据主权目的、数据主权性质、数据主权内容、数据主权特征、数据主权类型和数据主权场景六个相关概念，每个相关概念内部又存在诸如数据保护、政治主权、控制权、绝对性、硬数据主权和数据价值释放等其他概念。各概念的“实体-关系-属性”构成了数据主权概念体系与模型，数据主权概念体系中的各概念之间存在关联关系、整体-部分关系和属种关系，数据主权概念模型中的相关概念之间存在一对多关系和多对多关系。

Constructing the concept system and model of data sovereignty will not only promote the practical application of Chinese data sovereignty, but also contribute to exporte our independent discourse system of data sovereignty to the world. Text analysis and content analysis are used to deconstruct the conceptual connotation of data sovereignty and refine the cognitive dimension. On this basis, the relationship between concepts is clarified, and the conceptual system is finally constructed and modeled. From the cognitive dimension, six concepts related to the purpose, nature, content, characteristics, types and scenarios of data sovereignty can be deduced. Within each of these concepts lie other concepts such as data protection, political sovereignty, control, absoluteness, hard data sovereignty, and data value release. The "entity-relationship-attribute" of each concept constitutes the conceptual system and model of data sovereignty. Among the concepts in the conceptual system of data sovereignty, there are correlation relations, whole-part relations and species relations; among the related concepts in the conceptual model of data sovereignty, there are one-to-many relationship and many-to-many relationship.
