用生成式AI处理邮件，白领每周少花两小时，还能减少加班。
Shifting Work Patterns with Generative AI
- 随机分配员工使用嵌入办公软件的AI工具，观察工作模式变化。
- 80%使用者每周邮件时间减少2小时，非工作时间工作也下降。
- 虽个人效率提升，但任务量和类型未明显改变，适合关注职场效率者。
我们基于66家企业的实地实验，对7,137名知识型员工进行了研究。员工被随机分配使用集成于现有工作应用中的生成式AI工具，用于处理邮件、会议和写作。在为期六个月实验的后半段，使用该工具的80%员工每周邮件时间减少两小时，并减少了非正常工作时间的工作时长。除个体层面的时间节省外，我们未发现个人层级的AI使用导致工作任务数量或构成的显著变化。
原文摘要 · Abstract (English)
We present evidence from a field experiment across 66 firms and 7,137 knowledge workers. Workers were randomly selected to access a generative AI tool integrated into applications they already used at work for email, meetings, and writing. In the second half of the 6-month experiment, the 80% of treated workers who used this tool spent two fewer hours on email each week and reduced their time working outside of regular hours. Apart from these individual time savings, we do not detect shifts in the quantity or composition of workers' tasks resulting from individual-level AI provision.
