This paper studies the effect of servitization, i.e., within-establishment changes in the labor force composition towards higher shares of workers with service occupations, on within-establishment wage inequality. We identify servitization as being a main driver of increasing within-establishment wage inequality. Servitization accounts for roughly 7% of the observed increase in the within-establishment wage inequality in manufacturing industries between 1994 and 2017. Higher servitization of an establishment’s labor force is associated with, on average, a lower wage level for otherwise equal workers across the majority of occupations. The wage decrease is particularly pronounced for workers in low-skilled manufacturing occupations and workers at the lower end of the wage distribution. These heterogeneous wage effects explain the increase in within-establishment wage inequality.

本文研究了服务化对机构内工资不平等的影响，即机构内劳动力构成向更高比例的服务业工人转变。我们认为服务化是增加机构内工资不平等的主要驱动因素。在 1994 年至 2017 年间观察到的制造业机构内工资不平等的增加中，服务化约占 7%。机构劳动力的更高服务化与平均而言，大多数平等工人的工资水平较低的职业。低技能制造业的工人和工资分布低端的工人的工资下降尤为明显。
