80% 高管未見 AI 生產力提升

🔑 增強重點摘要

• •A National Bureau of Economic Research (NBER) survey of nearly 6,000 executives across the US, UK, Germany, and Australia found over 80% report no AI impact on productivity or employment in the past three years[1][2][3].
• •While 69-70% of firms use AI, executive usage averages only 1.5 hours per week, with 25% not using it at all; common applications include text generation, visual content, and data processing[1][2][3].
• •Executives expect AI to boost productivity by 1.4%, output by 0.8%, and reduce employment by 0.7% over the next three years, though employees anticipate job growth[1][2][3].
• •Contrasting views exist: Morgan Stanley survey of 935 executives in AI-exposed sectors reports 11.5% productivity gains and 4% headcount reduction after one year of use[4].
• •PwC surveys indicate over half of leaders see no revenue or cost benefits yet, but 30% report revenue uplift; early adopters at enterprise scale are gaining traction amid a 'J-curve' effect[5].
