Abstract
This article aims to estimate the contribution of KIBS to the innovation system. Data on innovation gathered from national and European databases are analyzed using a methodology based on an input-output framework to estimate the drive for innovation in the Spanish economy and the contribution of KIBS. KIBS are found to be crucial to both the creation and diffusion of innovation. From among the four classifications of sectors analyzed herein, KIBS is found to be the only significant net generator of innovation. © 2011 Springer-Verlag.
