Consumer Co-creation’s Influence on New Product Adoption and the Diffusion of Innovation

Abstract - Consumer co-creation has become a defining paradigm in contemporary marketing and innovation management. By actively involving consumers in ideation, design, and value creation processes, firms can enhance product relevance, foster stronger customer engagement, and accelerate the diffusion of innovation. Despite growing attention, the mechanisms linking co-creation to new product adoption and diffusion remain underexplored. This conceptual paper synthesizes literature on co-creation, adoption, and diffusion theories to propose an integrated framework. The paper argues that consumer co-creation enhances adoption through mechanisms such as perceived value, trust, and network externalities, while also reshaping diffusion patterns by leveraging social contagion and digital communities. The proposed model highlights key propositions and provides directions for future research.
