Idea creation and concept development in family business sustainability: The mediating role of couples relationships

This study examines the ideals of idea creation and concept development in couples’ relationships and family business sustainability. Guided by dynamic capability theory and commitment–trust theory, this study explores how couple relationships mediate idea creation, concept development, and family business sustainability. Using a survey, this study adopted a quantitative approach and collected data from 259 couples who owned family businesses in Greater Accra. SmartPLS 4 was used to formulate the model. The results revealed that couples’ relationships significantly affected concept development, idea generation, and family business sustainability. This study recommends that couples or family businesses invest in idea creation and concept development together, as this helps build trust and sustain their family businesses. This study’s conceptualization of the Couprenuership Model raises our understanding of idea creation, concept development, family businesses, and couples’ relationships.
