41 國研究：採用 AI 的企業整體增聘，但集中在資深職位、初級職位減少
AI Use at Companies is Adding Jobs, But Mostly in Senior Roles
摘要分析
彭博報導史丹佛 Bharat Chandar 與倫敦國王學院 Bouke Klein Teeselink 於 2026 年 9 月 21 日發表、涵蓋 41 國企業的研究：採用 AI 的公司整體增聘幅度高於未採用者，但成長明顯偏向資深員工——五年間資深職位人數增加 6.7%，初級職位減少 3%；儘管整體招募增加，初級員工占比下降 1.9 個百分點。此趨勢出現在巴西、沙烏地阿拉伯、英國等多國，顯示是結構性現象。研究呼應 2026 年其他證據：即使總就業成長，AI 仍在掏空初級職位、擴大對有經驗人才的需求。
- 41 國研究：採用 AI 的企業整體增聘
- 資深職位五年增 6.7%，初級職位減 3%
- 初級員工占比下降 1.9 個百分點
- 趨勢橫跨巴西、沙烏地、英國等多國
- AI 改變的是勞動力結構而非總量
Bloomberg reports on a new study by Bharat Chandar of Stanford University and Bouke Klein Teeselink of King's College London, released September 21, 2026, spanning companies in 41 countries. Firms adopting AI added more jobs overall than non-adopters, but the gains sharply favored senior employees: senior headcount rose 6.7% over five years at AI-adopting companies while junior employment declined 3% in the same period. Although overall hiring increased, the share of junior workers at those companies fell by 1.9 percentage points. The shift away from lower-level workers appeared across numerous countries including Brazil, Saudi Arabia and the UK, suggesting a structural pattern rather than a local anomaly. The findings reinforce other 2026 evidence that AI is reshaping the composition of the workforce—hollowing out junior roles while expanding demand for experienced staff—even where total employment grows.
