AI 提效 3% 但零变现：丹麦万人实证

为什么值得看
Humlum 和 Vestergaard 将 2.5 万丹麦员工的 AI 使用数据与真实 payroll 记录关联，发现 AI 仅节省约 2.8% 工时且未转化为收入提升。这是首个链接微观采用行为与宏观薪酬结果的实证研究，直接挑战当前企业 AI ROI 叙事。
编辑判断
这项研究的致命价值在于方法论：之前 90% 的 AI 生产力研究依赖自我报告问卷，而丹麦的行政数据链接打破了'用户觉得自己变快了'和'公司真省钱了'之间的幻觉链条。2.8% 的节省集中在写作和客服，但企业并未因此调整薪酬结构或缩减 headcount——这意味着 AI 红利目前被员工以'摸鱼时间'的形式私吞，或被新的协作摩擦抵消。
对 AI 创业者和内部效率团队的 actionable 判断：如果你卖的是'降本'，客户 CFO 很快会要求看到 payroll 层面的证据，而不是 DAU 或 token 消耗；如果你做的是 AI coding 或 agent 工具，需要主动设计'节省工时→可量化产出→薪酬/绩效挂钩'的闭环，否则 3% 就是天花板。

核心争论：AI 提效能否转化为经济回报，以及研究数据时效性是否足以支撑结论
Saving time does not automatically translate into higher productivity, or even lower costs. That should be obvious? In fact, I would argue the that with AI, companies should expect to spend more on average, without necessarily seeing any meaningful cost savings nor increase in profits. That does not
In what sense is AI like paying for ads? In one case you legitimately lose to the competition if you stop (prisoner's dilemma). In other case, whether and how much you lose depends almost entirely on how much it actually impacts your productivity in practice (or not). If you're referring to the publ
If we assume everyone has access to the same AI tools and those tools do help improve output a lot then you get the same prisoner's dilemma as ads. The people using the AI tools to improve their output will set higher consumer expectations for their product or service. If you do not also use AI, you
