This paper aims to encourage the discussion as well as to promote a better understanding of the relationships between the key dimensions in the Portuguese knowledge-intensive business services (KIBS) (namely, innovation, knowledge, networks, location, and internationalisation). The motivation for this research is based on the objective to reach a deeper understanding of the relationships between KIBS and other firms, especially with their clients, analysing the effects on innovation and internationalisation processes, taking into account knowledge, networks and location. The current study follows a qualitative methodology approach, applying semi-structured interviews to chief executive officers (CEOs) of the Portuguese KIBS firms and specialised academics on KIBS and innovation. The results suggest that KIBS play an important role in transferring knowledge, thus contributing, in different forms, to the processes of firms' innovation and internationalisation. The obtained results are important for firms involved in networks regarding technology as well as the creation of new products/services or new markets.
