Knowledge is a key resource in any organization, and during a reshoring process, transferring knowledge to the home market is crucial. This study offers an in-depth comprehension of the factors influencing the knowledge transfer process in companies conducting in-house reshoring. We applied a qualitative multiple case study approach of Swedish organizations that fulfilled the criteria for in-house reshoring. Similar to other knowledge transfer processes, knowledge transfer during in-house reshoring is influenced by cultural, linguistic, and physical distances. Furthermore, reshoring motivation has an impact on the actors’ knowledge transfer motivation. This investigation clarifies knowledge transfer in the context of reshoring, and exposes the challenges of knowledge transfer during reshoring. The study signifies the importance of understanding reshoring motivation for the success of reshoring. It moreover contributes to the research on knowledge transfer by providing evidence of the influence of the role of knowledge on the choice of knowledge transfer methods. In addition, the study extends the research on the reverse direction of knowledge transfer, in terms of in-house reshoring scenarios.
