数据已成为当今社会发展的重要因素，但目前全球尚未形成统一的数据跨境流动规则。在此背景下，美国与欧盟相继构建起“外向干涉型”和“内向保护型”数据法域外适用体系，以加强对网络空间的规制力。此举存在滥用数据法域外效力的隐忧，增加了各国数据的被动开放风险，也抬高了企业全球经营的合规门槛。作为数字产业大国，我国亦应加强数据立法，构建“能动回应型”数据法域外适用体系，既要顺应国内数字市场发展的内向性要求，也应兼顾互联网企业走出去的外向性需要，推动我国数据法域外效力的合理适度延伸，并完善外国数据法不当域外适用的阻断机制，以此探索全球数据治理的中国范式。

Data has become a crucial element in contemporary social development, yet there is currently no unified global rule for cross-border data flow. Against this backdrop, the United States and the European Union have successively established “outward interference” and “inward protection” extraterritorial application systems for data laws to strengthen their regulatory power over cyberspace. This move raises concerns about the potential abuse of the extraterritorial effect of data laws, increasing the risk of passive data openness for various countries and raising the compliance threshold for global business operations. As a major digital industry nation，China should also strengthen its data legislation and construct a “proactive response” extraterritorial application system for data laws. This system should align with the inward requirements of the domestic digital market development while also considering the outward needs of internet enterprises going global. It should promote the reasonable and moderate extension of the extraterritorial effect of China's data laws and improve the blocking mechanisms against the improper extraterritorial application of foreign data laws, aiming to explore a Chinese paradigm for global data governance.
