牛津大学：2025AI计算主权的全球争夺战研究报告

Core Viewpoint - The global competition in artificial intelligence (AI) is increasingly focused on the physical foundation of computing power, leading to a silent war over "Compute Sovereignty" [2][3][4]. Group 1: Understanding Compute Sovereignty - Compute sovereignty is a complex issue that must be deconstructed into three levels: the location of AI computing resources, the nationality of the companies owning these data centers, and the origin of the AI accelerators (chips) powering them [2][3]. - A survey of nine leading public cloud service providers reveals a highly uneven global distribution of computing power, with only 33 countries hosting critical AI infrastructure, indicating a significant gap between "compute-rich" and "compute-poor" nations [3][4]. Group 2: Territorial Illusions and Economic Considerations - The concept of territorial sovereignty in computing power is primarily about having physical AI data centers within a country's borders, which is seen as essential for ensuring supply security and regulatory oversight [4][5]. - The report highlights that while attracting foreign tech giants to build data centers can bring economic benefits, the environmental and resource costs may outweigh these advantages, especially for countries lacking competitive energy and climate conditions [5]. Group 3: Supplier Loyalty and Geopolitical Strategies - Merely having data centers does not equate to true sovereignty; the nationality of AI cloud service providers introduces a layer of complexity due to overlapping legal jurisdictions [6][7]. - Countries face strategic choices between two approaches: "Aligning" with a single foreign superpower's digital infrastructure or "Hedging" by diversifying suppliers to mitigate risks [8][9]. Group 4: The Chip Dependency - The report identifies a critical dependency on AI accelerators, with U.S. companies like NVIDIA dominating 80% to 95% of the global market, leading to a situation where most countries rely on U.S. technology for their AI capabilities [10][11]. - Countries like the EU and China are striving for "strategic autonomy" in chip production, but achieving this is a long-term and costly endeavor [12][13]. Group 5: Conclusion on Sovereignty - The report concludes that compute sovereignty is not a straightforward goal but a complex framework filled with trade-offs, where a nation may achieve sovereignty in one area while remaining dependent in another [13].
