Effect of different types of knowledge intensive business services on innovation and performance Mendoza, Marlene Molina Fernández, Luis Miguel Ortega Egea, María Teresa In recent years, firms have increasingly used knowledge services provided by knowledge-intensive business services (KIBS), but evidence on their impact on customer outcomes is mixed. To explain these mixed findings, this research proposes two explanations: The mediating role of knowledge integration capability (KIC) and the differential impact of different types of KIBS. KIBS can be of different types: professional (P-KIBS), research and development (R&D-KIBS) and information and communication technology (ICT-KIBS). To test the hypotheses of the research model, data from 368 firms in a developing country (Ecuador) were collected using PLS-SEM software. The results show that the effect of KIBS use on customer performance is a more complex relationship than might be expected a priori, as it depends on several factors. First, the effect of P-KIBS on customer performance is mediated by the knowledge integration capability of the customer firm. Second, the effect of R&D-KIBS on innovation performance is direct but does not affect overall performance. Third, the results indicate that ICT-KIBS do not have a significant effect on customer performance. The analysis of these results indicates the need for further studies to understand the complexity underlying this relationship. 2025-11-07T11:45:42Z 2025-11-07T11:45:42Z 2025-01-01 journal article Mendoza, M., Molina, L.
