This study examines the impact of administrative culture, specifically adhocracy, clan, market, and hierarchy cultures, on product innovation in modern businesses. This study utilizes a survey-based method and employs structural equation modeling (SEM) to investigate the proposed hypotheses thoroughly. The research framework includes two essential elements: knowledge administration as a mediator and management support as a moderator to clarify the dynamics involved. Findings reveal a positive impact of organizational culture in terms of adhocracy, clan, and hierarchy culture on product innovation, except for market culture. Besides, knowledge management positively mediates the association between administrative culture as well as product origination. Also, management support positively moderates the relationship between knowledge management and product innovation. This study improves our understanding of the complicated connection between workplace atmosphere and new product development through a comprehensive survey and SEM analysis. Additionally, it offers practical suggestions for organizational leaders who aim to cultivate a culture that promotes ongoing innovation. The findings augment the expanding reservoir of knowledge in the realm of administrative comportment and innovation management, providing valuable discernment for both academic researchers and industry professionals.
