Abstract: Crossborder data flow is a fundamental part of digital trade, and it is also a key issue in the international data governance game. At present, China has preliminarily formed a system of rules and regulations for crossborder data flow, but there are still prominent problems such as difficulties in crossborder risk screening, slightly rough rules and systems, difficulties in the dominance of international rules, and weak crossborder regulatory means. To seriously  solve the problem of crossborder data flow, it is urgent to better coordinate development, security and openness to build a crossborder data governance system. The policy system clarifies basic propositions, improves the legal system, refines institutional rules, consolidates technology platforms and expands practice carriers, in order to align with highstandard international economic and trade rules, and gradually form a plan for crossborder data flow with Chinese characteristics.

Key words: crossborder data flow, data localization, digital trade, data elements, data governance

摘要： 数据跨境流动是开展数字贸易的重要基础，也是国际数据治理博弈的关键议题.当前我国已初步形成了数据跨境流动的制度规则体系，但仍存在跨境风险甄别困难、规则制度条款略粗、国际规则主导困难、跨境监管手段薄弱等突出问题.认真解决数据跨境流动问题，亟需更好统筹发展、安全、开放，构建数据跨境治理体系，明晰基本主张，健全法律体系，细化制度规则，夯实技术平台，拓展实践载体，更好对标国际高标准经贸规则，逐步形成数据跨境流动“中国方案”.
