The Effects of Generative AI on High-Skilled Work: Evidence from Three Field Experiments with Software Developers
通过微软、埃森哲和一家匿名财富100强公司的随机对照试验，发现使用AI编码助手使软件开发者完成任务数量增加26.08%，且经验较少的开发者受益更大。
This study evaluates the effect of generative artificial intelligence (AI) on software developer productivity via randomized controlled trials at Microsoft, Accenture, and an anonymous Fortune 100 company. These field experiments, run by the companies as part of their ordinary course of business, provided a random subset of developers with access to an AI-based coding assistant suggesting intelligent code completions. Although each experiment is noisy and results vary across experiments, when data are combined across three experiments and 4,867 developers, our analysis reveals a 26.08% increase (standard error: 10.3%) in completed tasks among developers using the AI tool. Notably, less experienced developers had higher adoption rates and greater productivity gains. This paper was accepted by Jean-Pierre Dube, marketing. Funding: M. Demirer and T.
