The Influence of Human Capital on Innovation Capabilities of Small and Medium Enterprises: The Mediating Roles of Structural Capital and Relational Capital
Main Article Content
Abstract
Human capital plays an important role in enhancing firms’ innovation capabilities. However, relatively few studies have examined the underlying explanation for this virtuous effect. This research aims to study the influence of human capital on small and medium enterprises’ innovation capabilities and to examine the mediating roles of structural capital and relational capital in the relationship between human capital and innovation capabilities. Survey data were collected by mail from 109 business owners or top executives from 109 SMEs in the manufacturing sector in the southern region of Thailand. Structural equation modeling (SEM) was used for the analysis of the proposed mediation model, this comprises two specific procedures: testing a measurement model and testing a structural model. Confirmatory Factor Analysis (CFA) was used in testing the measurement model. The results confirmed that human capital had a direct positive influence on structural capital and relational capital (β=0.736, β=0.604, p<0.001). Furthermore, human capital had an indirect positive influence on SMEs’ innovation capabilities via the mediating roles of structural capital and relational capital (β=0.241, β=0.175, p<0.05). The results from this research indicate that the human capital of SMEs plays an important role in fostering their firms’ structural and relational capital. Therefore, SME leaders should promote and develop human capital, structural capital, and relational capital, leading to the development of the organization's innovation capabilities.
