数据中心供配电设备行业跟踪：AI与数据中心景气延续，电力设备需求持续高企

Investment Rating - The report rates the industry as "Outperforming the Market" [3] Core Insights - The data center industry has become a core incremental application scenario for the power equipment sector, directly driving demand growth and technological iteration in power equipment [3][6] - The report emphasizes the need to incorporate multi-dimensional indicators from the AI industry to accurately assess the demand for power distribution equipment in data centers, given the capital expenditure scale and long investment return cycles in the data center sector [3][6] - The report outlines a three-part indicator system: 1. Demand side: Capital expenditure from leading cloud providers serves as a direct "weather vane" for short-term demand potential for power distribution equipment [3][6] 2. Supply chain: The investment rhythm in data centers is constrained by GPU supply, necessitating tracking of key supply chain data to validate demand progress [3][6] 3. AI application side: The development of AI applications directly impacts the strength and sustainability of capital expenditure cycles in data centers [3][6] Summary by Sections Demand Side: Sustained High Growth in Capital Expenditure - In Q3 2025, overseas cloud providers' capital expenditure reached $99.617 billion, a year-on-year increase of 80.39% and a quarter-on-quarter increase of 9.54% [8] - Alibaba's capital expenditure in Q3 2025 was 31,501 million yuan, a year-on-year increase of 80.10% but a quarter-on-quarter decrease of 18.55% [13] - Tencent's capital expenditure in Q3 2025 was 12,983 million yuan, a year-on-year decrease of 24.05% and a quarter-on-quarter decrease of 32.05% [13] Supply Chain: Revenue Growth for Key Players - NVIDIA's revenue in Q3 2025 reached 362.571 billion yuan, a historical peak with a quarter-on-quarter growth of 24.63% and a year-on-year growth of 62.49% [18] - TSMC's revenue in November 2025 was 343.614 billion New Taiwan dollars, a year-on-year increase of 24.5% [24] - The CPU price index in October 2025 was 98.20, showing a slight recovery from 96.15 in September, while DRAM spot prices surged over 200% from $12.85 to $38.76 [27] Application Side: Steady Growth in AI Models and Applications - The report notes a steady increase in the number of AI models and application deployments, which directly influence the capital expenditure cycles in data centers [29] - The token call volume on the OpenRouter platform reached 5.85 trillion from December 9 to December 15, reflecting a quarter-on-quarter growth of 1.21% [34] - The price of tokens for models scoring over 40 on the Artificial Analysis Intelligence Index dropped by over 50% in Q3 2025 [45]
