从“芯”到“电”，美银：中国AI基础设施非IT投资规模将达8000亿元

Core Insights - The essence of AI competition has shifted to an "electricity competition," with investment trends moving from traditional IT infrastructure to non-IT infrastructure such as power, cooling, and materials [1][6][12] - By 2030, China's non-IT infrastructure investment related to AI is expected to reach 800 billion RMB, with power systems dominating at 38%, followed by metals for data center construction at 12% and advanced cooling systems at 10% [2][9] Investment Trends - The investment wave in AI infrastructure is expanding beyond traditional chips and servers to include essential non-IT infrastructure [2] - Total capital expenditure for AI in China is projected to grow to 2-2.5 trillion RMB by 2030, with non-IT infrastructure accounting for one-third of this total [2] Power Consumption and Data Centers - The energy consumption of data centers in China is expected to grow at a compound annual growth rate (CAGR) of 18%, increasing from 102 TWh in 2024 to 277 TWh by 2030, representing 29% of global data center electricity consumption [3][9] - The rapid increase in power consumption is driven by the accelerated adoption of AI data centers (AIDC), which have significantly higher power requirements than traditional data centers [4] Key Drivers of Investment - The report identifies three main drivers for the surge in investment: the proliferation of AIDC, the deployment of high-performance chips, and the increasing power density of server cabinets [4][5][9] Opportunities in Power Supply - China has significant advantages in AI power infrastructure, including ample generation capacity, lower industrial electricity prices (30-60% lower than developed markets), a leading position in renewable energy supply chains, and a relatively young and robust power grid [12] - Five major investment opportunities are highlighted: nuclear power, electrical equipment, battery energy storage systems (BESS), diesel generators, and advanced power supply technologies [13][17][20][22][24] Cooling and Materials - Efficient cooling and essential raw materials are critical for AI infrastructure, with significant investment potential [25] - Liquid cooling technology is expected to grow rapidly, with a projected market size of 79 billion RMB by 2030, driven by the need for efficient heat management in high-density AI environments [26] - The demand for key metals such as copper and aluminum is also expected to rise, with copper consumption in AI data centers projected to reach approximately 1 million tons by 2030, accounting for 5-6% of national demand [27]
