基于中国家庭追踪调查（CFPS）2014—2020年四期面板数据，从理论和实证两个层面考察了互联网使用对农民工工作满意度的影响及其机制。研究发现：互联网使用并未改善农民工工作满意度，平均而言，互联网使用导致农民工工作满意度降低约9.4个百分点，这一负面影响在低技能（高中或以下学历）、新一代、男性和非正规就业农民工群体中表现得更为明显；使用互联网进行工作、学习、社交等方式对农民工工作满意度的影响存在异质性；就其作用机制而言，互联网使用可能通过加剧过度劳动和降低相对收入而降低农民工的工作满意度。

Based on the panel data of China Family Panel Studies (CFPS) from 2014-2020, the paper examines the impact of Internet use on migrant workers’ job satisfaction from both theoretical and empirical perspectives. The study found that Internet use did not improve migrant workers’ job satisfaction. On average, Internet use reduces migrant workers’ job satisfaction by about 9.4 percent. This was more pronounced among the low-skilled (high school education or below), male, new generation migrant, and informal employment groups. Heterogeneity exists in the impact of using the Internet for work, learning, and socializing on migrant workers’ job satisfaction. In terms of its mechanism, Internet use may reduce migrant workers’ job satisfaction by aggravating overwork and reducing relative income.
