Abstract

This research examines the relationship between Environmental, Social, and Governance (ESG) disclosure and firm value while investigating the moderating role of board size. The sample includes 20 companies listed on the Singapore Exchange for the period 2019 to 2024, utilizing secondary data from Bloomberg. Data analysis was performed using panel data multiple linear regression via Stata 17 software. Following model selection tests, the Fixed Effect Model was implemented with robust standard errors to mitigate heteroscedasticity. ESG disclosure was evaluated both aggregately and through its individual pillars, with moderation analysis conducted by generating interaction terms between ESG metrics and board size. The empirical results demonstrate that total ESG disclosure and its constituent pillars do not significantly influence firm value. However, moderation testing reveals that board size negatively moderates the impact of total ESG, environmental, and governance disclosures on firm value, whereas no moderating effect was detected concerning the relationship between social disclosure and firm value. These findings highlight the critical importance of board size optimization in ensuring that ESG transparency effectively contributes to the enhancement of firm value.
