专业邮件中的趣味人工智能：关于语气和收件人参与度的实地实验

中文摘要 AI 辅助

大语言模型正在迅速重塑职场沟通，但人工智能辅助写作是否以及如何改变收件人的实际行为尚不清楚。在一项随机交叉实地实验中，六家公司的121名员工在三周内分三种情况发送工作邮件：无辅助写作、GPT-5以趣味语气改写、GPT-5以专业语气改写。结果表明，趣味编辑增加了情感积极性，专业编辑降低了情感积极性，但两种情况都未直接改变打开率、回复率或响应时间。发件人自身的积极性强烈预测了打开邮件和回复邮件的可能性，这是人工智能编辑塑造行为的重要间接途径。这些发现表明，人工智能辅助沟通通过其产生的语言情感基调而非使用方式来塑造职场参与度。

英文摘要

Large language models (LLMs) are rapidly reshaping workplace communication, yet whether AI-assisted writing changes how recipients actually behave, and through what channel, remains unknown. Here, in a randomized crossover field experiment, 121 employees across six companies sent work emails under three conditions over three weeks: unaided writing, GPT-5 rewriting in a playful tone, and GPT-5 rewriting in a professional tone. Across 16,880 emails, playful editing increased emotional positivity (B=+0.068, p<0.001), and professional editing decreased it (B=-0.041, p<0.001), yet neither condition directly altered open rates, reply rates, or response times. Instead, within-sender positivity strongly predicted both opening (OR=2.05) and replying (OR=3.32, p<0.001), a significant indirect pathway through which AI editing shaped behavior, in the absence of any direct effect. These findings suggest that AI-assisted communication shapes workplace engagement not through its use, but through the emotional tone of the language it produces.
