Innovation, Green Management, and Value Creation in Indonesian Healthcare: The Mediating Role of Business Sustainability

This study examines how innovation and green management influence business sustainability and firm value in Indonesian healthcare companies. Innovation is measured using Value-Added Intellectual Capital (VAIC) efficiency, green management through Environmental, Social, and Governance (ESG) scores, business sustainability as carbon emission disclosure (CEDI), and firm value as Market Value Added (MVA). The sample consists of 123 firm-year observations from healthcare firms listed on the Indonesia Stock Exchange (2019–2023). Based on the capital-based theory of sustainability and stakeholder theory, hypotheses are tested using fixed-effect panel regression, Baron and Kenny mediation analysis, and Structural Equation Modelling (SEM). The results show that VAIC is the only significant predictor of MVA, with a consistent positive effect across all model specifications. Neither ESG Score nor CEDI shows a significant effect on market value, indicating that sustainability disclosure has not yet translated into measurable financial returns in this context. Within the structural model, ESG governance is the strongest predictor of carbon disclosure, while firms with higher VAIC tend to prioritise value creation over environmental reporting. All mediation hypotheses are rejected. These findings suggest that intellectual capital and sustainability practices currently function as separate strategic priorities in Indonesian healthcare. Intellectual capital produces tangible market value in the short term, while the financial benefits of sustainability disclosure are likely to emerge only as Indonesia’s ESG reporting standards and investor awareness continue to develop.
