The research project empirically assesses the influence of an under-researched aspect of social capital on the family firm’s entrepreneurial behaviors. Specifically, blending social capital, which consists of bonding social capital and bridging social capital that develops between family firms and external family stakeholders, is considered in examining the family firm’s engagement in innovation efforts. Additionally, familial tie strength and outside business ownership of external family stakeholders are argued to moderate the proposed relationship between blending social capital and family firm innovation. The surveying methods for assessing the hypothesized relationships included conducting a two-wave study with adapted, modified, and validated scales. Also, some variables were collected using the Mississippi Secretary of State, the U.S. Copyright Office, the U.S. Patent and Trademark Office, and the U.S. Census Bureau American Community Survey databases. The theoretical model is analyzed using hierarchical regression and moderated regression using IBM SPSS 28 Process Macro (Hayes, 2021), structural equation modeling with AMOS, and scale development techniques to ensure the validity and reliability of the measurement instruments. The goal is to identify potential antecedents for enhancing the innovation capabilities of family firms.
