# 国信证券：伴随模型能力提升 AI 基础设施需求快速增长

> 国信证券发布研报指出，AI 基础设施需求快速增长，云/AI 平台将重新选择。微软在 B 端基础设施方面表现突出，谷歌和亚马逊各有侧重，国内字节跳动和阿里巴巴在市场中占据重要地位。随着模型能力提升，推荐关注微软、谷歌、亚马逊、阿里巴巴、腾讯控股及英伟达等 AI 云平台和芯片厂商。

国信证券发布研报表示，AI 背景下 AI Infra 层面临重构，客户将重新选择云/AI 平台，云厂加大布局 AI/Agent 平台瓜分新市场：微软聚焦 B 端基础设施，是市场上模型支持最全面的平台，工具链和生态整合全面，安全与稳定性强，云收入增速显著领先；谷歌依托 AI Studio 兼顾 B/C 端多场景，多模态强但生态不成熟、市占率较低；亚马逊依托 AWS 服务中小企业为主，侧重算力销售与便捷部署但工具链分散。国内字节扣子覆盖全场景，开发者与智能体数量领先；阿里百炼主攻 B 端全行业、服务 30 余万企业客户，MCP 工具链和开源生态丰富。伴随模型能力提升、AI Infra 需求快速增长，推荐 AI 云平台厂商：微软、谷歌、亚马逊、阿里巴巴、腾讯控股，AI 芯片厂商英伟达与 AI Data Infra 数据服务厂商。
