复旦大学国际问题研究院姜茗予助理研究员与日本青山学院大学经济学部安井健悟教授，日本神户大学经济学研究科勇上和史教授在国际期刊《Telecommunications Policy》上发表了题为“Working from home, job tasks, and productivity”的论文。该期刊同时被SSCI和SCI收录，根据2024年JCR报告，其SSCI和SCI均为一区。
简介：
关于远程工作与生产率之间的关系，现有研究提供了相互矛盾的证据。然而，鲜有研究探讨远程工作影响生产率的具体机制。鉴于此，本研究通过研究工作内容的变化，探究居家办公影响劳动生产率的机制之一，填补这一空白。本研究利用疫情前和期间的数据，实证研究居家办公对工作任务的影响。
美国麻省理工学院经济学家大卫·奥特尔（David Autor）等学者构建了任务分类，他们根据常规/非常规（routine/non-routine）和认知/操作（cognitive/manual）等两个维度对工作内容进行分类。
姜茗予等（2024）的研究结果表明，居家办公增加非常规分析类（non-routine analytic）任务，减少常规操作类（routine manual），而非常规互动类（non-routine interactive）、常规认知类（routine cognitive）和非常规操作类（non-routine manual）任务则保持不变。通过这种工作任务变化，居家办公带来更高的工资水平。转向居家办公以及增加信息和通信技术资本的使用，提高了劳动力对非常规任务的投入，从而提高了劳动生产率。

【Abstract】：
The COVID-19 pandemic has spurred global change from traditional office-based work to remote work, driven by policy interventions, and resulting in a significant number of employees worldwide transitioning to working from home. Existing research presents conflicting evidence regarding the relationship between remote work and productivity. However, few have examined the specific mechanisms through which remote work affects productivity. Given this, the present study bridges this gap by examining changes in job assignment as one mechanism in which working from home affects labor productivity. We empirically examine the impact of work-from-home (WFH) on job tasks using original data collected before and during the pandemic. Our results demonstrate that WFH increases non-routine analytic tasks and decreases routine manual tasks, while non-routine interactive, routine cognitive, and non-routine manual tasks remain unchanged. Furthermore, the negative impact of WFH on routine manual tasks is more significant for the groups that had more routine manual tasks before the pandemic. Meanwhile, the positive impact on non-routine analytic tasks is more pronounced for employees with fewer non-routine analytic tasks before the pandemic. Finally, through such task changes, WFH leads to higher wage rates. Our findings suggest that the switch to WFH and increased use of information and communication technology capital increases the input for non-routine tasks performed by labor, and, in turn, increases labor productivity.
