In this article, we intend to understand how structural, relational, and cognitive dimensions of social capital influence innovation outcomes on interorganizational and intraorganizational networks. For achieving this aim, we adopt meta-synthesis research design with nine selected qualitative case studies. We identified through our analysis the patterns of causal relationships among the variables presented on the case studies. The antecedents of social capital dimensions, the influence of the dimensions on reducing barrier or impediments for innovation and on the enhancement of enablers or facilitators of innovation outcomes, and the direct effects of social capital dimensions on innovation compose the resulting framework. We found a balanced relation among the dimensions on interorganizational settings, with a prevalence of the relational dimension. Regarding interorganizational networks, we perceived a reduced role of structural dimension and the absence of the influence of social capital dimension of reducing barriers or impediments for innovation.
