ABSTRACT: With the development of information technology, data security has become a hot issue of concern for all countries. Data security legislation and data governance have become an important legal guarantee for the steady and sustained development of the digital society. China’s Data Security Law needs to balance the values of security and development, clarify the normativity and uniformity of the core categories of data, examine the legitimacy of state public power’s involvement in data governance, and reasonably set up the review rules for cross-border data transfer. In the future, it is necessary to establish a data security legislative framework, give full play to the multiplier effect of data elements, benchmark international rules, optimise the regulatory measures for cross-border data flow, establish and improve the data security rule system in the field of artificial intelligence, and contribute Chinese wisdom to the establishment of an international data governance and global data rule system.
