The maritime sector’s digital transformation requires not only technology adoption but also workforce capability development. While the Technology–Organization–Environment (TOE) framework explains organizational technology adoption and TAM/UTAUT explain individual technology use, neither adequately explains how contextual conditions translate into workforce capabilities. Addressing this gap, this study develops and tests a Maritime Human-Capital Transformation Model for Society 5.0, emphasizing human capability and resilience. An exploratory sequential mixed-methods design was employed, comprising in-depth interviews with 15 maritime stakeholders from four stakeholder groups, followed by a survey of 250 maritime professionals analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results demonstrated satisfactory reliability and validity across all constructs. Qualitative findings identified three competency dimensions: hard digital skills, socio-technical skills, and psychological readiness. Quantitative results showed that Technological Readiness, Organizational Support, and Environmental Pressure significantly influenced Digital Competency Adoption and Human Capital Transformation Effectiveness. Technological Readiness had the strongest effect on Digital Competency Adoption (β = 0.586, p < 0.001), while Digital Competency Adoption positively influenced transformation effectiveness (β = 0.364, p < 0.001) and partially mediated all three TOE relationships. The model explained 51.5% of the variance in Digital Competency Adoption and 50.9% in Human Capital Transformation Effectiveness. These findings extend the TOE framework by positioning digital competency adoption as a key mechanism linking contextual conditions to human-capital transformation in the maritime sector, advancing a human-centered approach to digitalization aligned with Society 5.0.
