This exploratory study seeks to promote investigation about knowledge sharing between enterprises of the same enterprise group and is motivated by the growing importance of knowledge management (KM) to businesses. The data was collected from Community Innovation Survey (CIS) 2012 and three linear regressions were performed (one to all enterprises, one to SME and one to large enterprises). The results show that cooperation for product or process innovation and service innovation influence knowledge sharing between enterprises of the same enterprise group, contributing to learning organizations. The present paper clarifies the importance of innovation and cooperation for innovation in KM practices between enterprises of the same enterprise group. The results are only valid to SME, since large enterprises have different practices of KM. © Copyright 2017, IGI Global.
