AI中文摘要:
本文研究了在地缘经济碎片化背景下,人工智能(AI)依赖专业化、可流动投资的经济体中,地缘经济碎片化如何影响国际资本配置。我们构建了一个包含AI专用资本和跨境资产持有中地缘政治摩擦的异质性主体开放经济模型。这些摩擦降低了资本流动性,提高了AI采用成本,并在国家和家庭之间产生了分配效应。定量结果表明,碎片化造成的福利损失随地缘政治距离呈非线性上升。这些损失对AI落后经济体和低财富家庭更大,主要通过投资减少、劳动收入减弱和金融条件收紧等渠道产生。本文还定义了一个所谓的“碎片化-AI三难困境”:经济体无法同时保持货币政策自主性、维持高效的AI资本配置以及免受地缘政治冲击的影响。
英文摘要:
This paper studies how geo-economic fragmentation affects the international allocation of capital in an economy where artificial intelligence (AI) relies on specialized, mobile investment. We develop a heterogeneous-agent open-economy model with AI-specific capital and geopolitical frictions in cross-border asset holdings. These frictions reduce capital mobility, raise the cost of AI adoption, and generate distributional effects across countries and households. The quantitative results show that fragmentation produces welfare losses that rise nonlinearly with geopolitical distance. These losses are larger for AI-lagging economies and for low-wealth households, mainly through reduced investment, weaker labor income, and tighter financial conditions. The paper also defines a so-called Fragmented-AI Trilemma: economies cannot simultaneously preserve monetary autonomy, maintain efficient AI-capital allocation, and insulate themselves from geopolitical shocks.
