2025年上半年，美国整体GDP增长1.6%，但细观其结构，增长动力近乎完全倾斜于数据中心和信息处 理技术领域的巨额投资，其他经济领域的贡献微乎其微，增长率仅为0.1%。据预测，2025年美国人工 智能数据中心支出规模将高达5200亿美元。然而，这种增长主要由微软、谷歌、亚马逊、Meta等科技 巨头驱动，而非由AI技术广泛应用带来的消费侧扩张或生产效率的实质性提升。这些企业动辄投入数 百亿乃至近千亿美元用于"军备竞赛"式的算力堆砌，却普遍面临投资回报率难以预期的风险。美国AI产 业在受到资本追捧的同时，未来是否可持续，更值得关注。 高资本刺激的AI增长模式是否具有可持续性，以及跟随性需要慎思。 另一方面，随着模型规模扩大，训练成本呈指数级增长，但模型性能的提升曲线可能逐渐平缓，单纯堆 砌算力无法实现真正的通用智能，然而，为了在技术上保持领先，企业只能持续投入，这是一种被迫 的"军备竞赛"，可能导致算力成为当前AI产业发展中最大的泡沫。 多个维度实现均衡发展 风险值得高度关注 当前，美国AI经济发展高度依赖资本投入，而非依靠全要素生产率提升或消费市场繁荣。AI产业的突 破性进展，首先需要数据中心、电网和硬件的建 ...
