Global PC Shipments Plunge 20.1% in Third Quarter of 2026 as Inventory Pull-In and High Prices Dent Demand

国际数据公司（IDC）于2026年10月8日发布的初步数据显示，2026年第三季度全球个人电脑（PC）出货量同比下降20.1%至6270万台；环比亦下滑9.1%，打破了以往的季节性增长规律。造成此次下滑的主要原因在于供应受限、宏观经济环境恶化，以及今年早些时候渠道端出现的提前备货——此前受AI数据中心建设带动存储价格上涨影响，渠道商纷纷提前囤货，从而透支了后续需求。各大主要厂商出货量均大幅下滑：惠普大跌30.9%，戴尔科技下滑25.0%，联想萎缩22.6%，苹果下降11.3%。IDC警告称，尽管短期内可能出现促销打折，但居高不下的价格和更大范围的经济逆风可能会使需求低迷态势延续至2027年。

Worldwide PC shipments fell 20.1% year over year in the third quarter of 2026 to 62.7 million units, according to preliminary data released by IDC on October 8, 2026. Shipments also declined 9.1% quarter over quarter, disrupting normal seasonal growth. The downturn was driven by supply constraints, worsening macroeconomic conditions, and an inventory pull-in earlier in the year as channels stocked up ahead of memory-driven price hikes linked to AI data center build-outs. Major vendors absorbed heavy declines: HP Inc dropped 30.9%, Dell Technologies fell 25.0%, Lenovo contracted 22.6%, and Apple decreased 11.3%. IDC warned that while near-term promotional discounting may occur, elevated prices and broader economic headwinds could depress demand into 2027.
