为高效联通数据资源，畅通数据资源大循环，推动数据经济发展，需要统筹数据流通与安全。其中，数据标准化是数据流通的前提，数据安全是数据经济的基石，保障体系是数据市场的核心。面向数据流通中的数据安全问题，论述数据流通与数据安全的关系，梳理基于安全的数据流通指导性规范建设。围绕数据标准体系建设，数据流通中元数据标准的统一、数据分类分级制度的健全、数据流通与保护标准的确立，以及可流通数据安全标准的构建是关键议题。从数据流通与安全的保障体系来看，数字安全基础设施智能升级、数据要素供给质量强化与数据流通服务优化是重要着力点。

To efficiently connect data resources, smooth the general circulation of data resources, and promote the digital economy, it is necessary to harmonize data circulation and security. Among them, data standardization is the premise of data circulation, data security is the cornerstone of data economy, and security system is the core of data market. Based on the issues of data security in data circulation, we have discussed the relationship between data circulation and data security, and explored the construction of security-based guiding norms for data circulation. Focusing on the construction of data standard system, the unification of metadata standards in data circulation, the soundness of data classification and grading system, the establishment of data circulation and protection standards, and the construction of security standards for circulating data are key issues. From the perspective of data protection system construction, the intelligent upgrading of digital security infrastructure, the strengthening of data element supply quality, and the optimization of data circulation services are the important points.
