Abstract

This study aims to provide empirical evidence on the mediating role of Good Corporate Governance (GCG) in the relationship between capital structure, investment opportunity set (IOS), corporate social responsibility (CSR), and firm value in state-owned enterprises listed on the Indonesia Stock Exchange during the 2019–2024 period. The population comprised all 24 listed state-owned enterprises, from which 14 firms were selected using purposive sampling based on predetermined criteria. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS 3.0, applying both outer and inner model evaluations. The findings indicate that CSR and capital structure do not have a direct significant effect on firm value, whereas the investment opportunity set positively influences firm value. Furthermore, Good Corporate Governance strengthens the relationship between CSR and firm value as well as between capital structure and firm value. However, GCG does not moderate the relationship between the investment opportunity set and firm value. These findings highlight the strategic importance of governance mechanisms in enhancing the value relevance of corporate financial and social policies within state-owned enterprises.

Abstract

This study aims to examine the relationships among credit dynamics, foreign direct investment, energy, economic growth, and environmental degradation in Indonesia from 1990 to 2024. Using a quantitative path analysis, this study examines the direct and indirect effects of working capital credit, consumer credit, foreign direct investment (FDI), and electricity consumption on environmental degradation via economic growth. The results reveal that all variables have a positive and significant effect on economic growth, with electricity consumption (β = 0.361; p < 0.007) being the primary contributor. Economic growth and electricity consumption also significantly increase environmental degradation, supporting the Environmental Kuznets Curve (EKC) hypothesis in Indonesia. Moreover, the analysis of indirect effects shows that economic growth mediates the relationships among credit distribution, FDI, and environmental degradation. This research is important because it examines sustainable development in Indonesia, where economic growth driven by the financial sector, FDI, and electricity consumption could increase carbon emissions and environmental degradation. These findings are relevant because they provide empirical evidence on the impact of financial and energy activities on environmental quality, both directly and through economic growth, in line with Indonesia's commitment to the SDGs and the green economy transition.
