The study of intellectual capital has gained interest in today’s highly competitive landscape. Using intellectual capital as a mediator, this paper developed an integrated model to examine whether organization learning affects and increases the capacity for new service development (NSD). The results from the study of 598 hotel managers support this model across multi-dimensions of intellectual capital and show that intellectual capital plays a mediating role between organizational learning and NSD. This paper also finds exploitative organization learning enhances the positive effect of organization capital because it fosters a positive link between relational capital and human capital. The study also discusses how this intriguing pattern of mediation could be explained by using theory and research with a regulatory focus.
