Abstract: With the advent of the era of big data, the process of globalization is accelerated, the economic and political exchanges between countries become more frequent, the competition for data becomes more and more fierce, and the cross-border flow of data is inevitable. Although the European Union, the United States and other major international economies give priority to the deployment of cross-border data, which provides effective reference for different countries, with the increasingly urgent demand for cross-border data flow, the related issues of national security and personal data protection are gradually highlighted. First, by combing existing research works on cross-border data flow, starting from the concept of data cross-border, we summarize their advantages and disadvantages; then, starting from the core data security technology and regulatory mechanism, we systematically analyze and compare cross-border data current situation of the flow of multiple countries ; finally, based on the collation and summary of existing works, we discuss the shortcomings and challenges of China's existing data cross-border management system, put forward targeted suggestions and solutions, and look forward to the research and development trends in this field.

摘要: 大数据时代的来临加快了全球化的进程,让国家之间的经济和政治上的交流变得更加频繁,关于数据的竞争也越来越激烈,数据的跨境流动也已经无法避免.虽然欧盟、美国等国际主要经济体优先对数据跨境进行了部署,为不同国家提供了有效的参考意见,但随着数据跨境流动的需求日益迫切,与之相关的国家安全、个人数据保护问题也逐渐凸显.首先,通过梳理跨境数据流动的现有研究工作,从数据跨境概念出发,归纳其利弊;接着,从其中核心的数据安全技术和监管机制切入,系统地分析和对比多个国家数据跨境流动现状;最后,依据对现有工作的整理与总结,探讨中国现有数据跨境管理体系的不足和面临的挑战,提出针对性的建议和解决方案,并展望该领域的研究和发展趋势.
