The Influence of Intellectual Capital on Innovation Performance: The Mediating Role of Knowledge Sharing and Innovation Culture (A Study on Startups Fostered by UNS)

This study examines the effects of intellectual capital on innovation performance mediated by knowledge sharing and innovation culture, focusing on startups fostered by Sebelas Maret University (UNS). The study evaluates the impact of human capital, relational capital, and structural capital on innovation performance, as well as the mediating roles of knowledge sharing and innovation culture. The findings reveal that human capital has a positive but insignificant effect on innovation performance, while relational and structural capital show positive and significant effects. Human capital, relational capital, and structural capital have a positive and significant influence on knowledge sharing. In the context of innovation culture, human capital and structural capital have significant effects, while relational capital has no significant impact. Knowledge sharing serves as an important mediator in the relationship between human capital and innovation performance, although its role is weaker for relational capital and structural capital. Conversely, innovation culture shows limited mediating effects on innovation performance, with structural capital being the main contributor to fostering an ecosystem that supports an innovative culture. This study provides practical implications for startup managers, emphasizing the importance of strategically leveraging intellectual capital. Recommended strategies include developing human capital through training programs, enhancing relational capital through strategic partnerships, and strengthening structural capital by implementing flexible and collaborative systems.
