人们普遍认为，人工智能可以帮助员工完成日常工作任务，从而节省他们的时间。但它究竟能让员工的工作效率提升多少呢？
根据美国人口普查局的最新数据，约55%的员工表示他们在工作中使用人工智能，其中约三分之一的人表示，人工智能将完成某项任务所需的时间缩短了1至2小时。
员工如何在工作中使用人工智能？
员工表示，他们会借助人工智能完成写作、产生新创意、开展研究以及处理行政事务等各类任务。
以下是他们表示最常在工作中使用人工智能的场景：
- 37%的人用它搜索信息或寻求技术帮助
- 32%的人用它撰写或草拟文本
- 32%的人用它生成创意
- 31%的人用它解读、翻译或总结信息
- 27%的人用它处理行政事务
- 21%的人用它进行数据分析或可视化呈现
- 16%的人用它开展辅导或培训
- 12%的人用它提供客户支持
根据人口普查局的数据，还有一小部分员工使用人工智能编写代码、提供医疗护理以及管理物流或供应链。
此次调查结果基于人口普查局每周开展的全国家庭和个人调查，调查内容涵盖就业、食品与营养以及交通等话题。
人工智能能为员工节省多少时间？
根据人口普查局的数据，在报告工作中使用人工智能的员工中，有四分之一的人表示，人工智能将原本完成一项任务所需的时间缩短了不到一小时。
另有15%的员工获得了更显著的效率提升，表示人工智能将每项任务的工作量减少了3小时。还有15%的员工表示，人工智能为他们节省了4小时的时间。
需要明确的是，员工学习使用人工智能这类新技术需要花费时间，最初反而可能会增加完成任务所需的时长。麻省理工学院的研究显示，制造业采用人工智能初期会导致生产率下降，但最终会帮助员工实现长期的效率提升。
经济学家用“J曲线模型”来解释这一现象。呈字母J形的生产率轨迹，反映了企业投入大量资源学习和投资新技术的阶段：生产率最初会出现下滑，随后呈指数级增长。

Artificial intelligence is believed to save workers time by helping them complete their daily tasks. But just how much more efficient can it make employees?
About 55% of workers say they use AI on the job, with about one-third of those reporting it cuts the time they need to complete a given assignment by one to two hours, according to new data from the U.S. Census Bureau.
How are workers using AI on the job?
Workers reported turning to AI for help with tasks including writing, generating new ideas, conducting research and completing administrative tasks.
Here’s how they say they most frequently use AI on the job:
- 37% use it to search for information or technical help
- 32% to write or draft text
- 32% to generate ideas
- 31% to interpret, translate or summarize information
- 27% for administrative tasks
- 21% for data analysis or visualization
- 16% for tutoring or training
- 12% for customer support
A smaller share of workers use it to write code, for medical care and to manage logistics or supply chains, according to the Census data.
The findings are based on a weekly national Census Bureau survey of individuals and households on topics including employment, food and nutrition, and transportation.
How much time does AI save workers?
One-quarter of employees who reported using AI at work say the tools shaved less than an hour off the time it would otherwise have taken them to complete a task, according to the Census data.
A smaller share, at 15%, of workers saw even greater efficiency gains, saying that AI cut their workloads by three hours per task. An additional 15% said it saved them four hours.
To be sure, it can take time for employees to learn to use new technology like AI, which can initially add hours to the time required to complete a task. Research from the Massachusetts Institute of Technology shows that AI adoption in manufacturing initially decreases productivity before ultimately helping workers achieve long-term gains.
Economists use the “J-curve” model to explain the phenomenon. The productivity trajectory, in the shape of the letter J, reflects the period when considerable resources are committed to learning and investing in new technologies, with productivity initially dipping before rising exponentially.
