Abstract Previous research shows that knowledge integration mecha- nisms (KIMs) mediate the cross-functional collaboration- product innovation performance relationship; however, this mediating effect seems to be rather weak. This study, in contrast, develops a moderated mediation (MOME) model to argue that such a mediating effect is moderated by product innovativeness. A sample comprised of 106 manufacturing firms is utilized in the analyses. A moderated-mediation approach shows that the mediating effect of KIMs in the linkage between cross-functional collaboration and product innovation performance varies by different perspectives of product innovativeness. From an industry (macro-level) per- spective, product innovativeness positively moderates the mediating effect of KIMs on product innovation perfor- mance; in contrast, such a moderating effect is not significant under a firm (micro-level) perspective.

La présente étude par contre élabore un modèle de médiation modérée (MOME) pour montrer qu’un tel effet médiateur est modéré par l’aspect novateur du produit. Un échantillon composé de 106 industries manufacturières est utilisé dans les analyses. Une approche de médiation mod- érée indique que l’effet médiateur des KIMs dans la relation collaboration interfonctionnelle- performance dans la créa- tion de nouveaux produits varie en fonction des différentes perspectives liées à l’aspect novateur des produits. Du point de vue du secteur d’activité (au niveau macro), l’aspect novateur des produits modère positivement l’effet médiateur des KIMs sur la performance dans la création des nouveaux produits; à l’opposé, un tel effet modérateur est insignifiant dans la perspective d’un établissement (niveau micro).

Although many academic studies on new product development (NPD) have been conducted over the past decades (Gupta, Raj, & Wilemon, 1985; Song, Mon- toya-Weiss, & Schmidt, 1997), there are still some unan- swered questions regarding the effect of cross-functional 29: – (2012) 25 39 9 February 2011 29(1), 25–39 (2012) 25
