When Social Responsibility Meets Profitability: Determinants of Firm Value in Indonesian Mining Companies Listed on the Indonesia Stock Exchange

This study examines the effect of Corporate Social Responsibility (CSR) disclosure and profitability ratios on firm value among mining sector companies listed on the Indonesia Stock Exchange (IDX). CSR disclosure was measured using an index based on the Global Reporting Initiative (GRI) Standards 2016, while profitability was proxied by four indicators: Return on Equity (ROE), Return on Asset (ROA), Gross Profit Margin (GPM), and Net Profit Margin (NPM). Firm value was measured using Price Book Value (PBV). The sample was selected through purposive sampling from a population of 46 mining companies listed on the IDX during 2020–2024, resulting in five companies that met all the criteria and a total of 25 observations. Data were analyzed using multiple linear regression with SPSS following classical assumption testing. The results show that CSR disclosure has a positive and significant effect on firm value. Among the four profitability indicators, only ROE has a significant positive effect on firm value, while ROA, GPM, and NPM have no significant effect. Simultaneously, CSR and profitability ratios significantly affect firm value, with a coefficient of determination of 80.2%. These findings are relevant amid the recent slowdown in Indonesia’s mining sector and the ongoing transition of sustainability reporting regulation toward standards aligned with the International Sustainability Standards Board (ISSB).
