The Nexus between ESG and Corporate Performance: Evidence from Pakistan

Abstract

This study examines the environmental, social, and governance (ESG) and Corporate Performance nexus for companies listed on the Pakistan Stock Exchange (PSX). This study utilises a balanced panel dataset of 740 firm-year observations across 27 sectors, making this analysis one of Pakistan's most comprehensive ESG performance studies. ESG is delineated into its constituent dimensions of the environment, social, and governance, and their relationships with the internal performance indicators (ROA, ROE, FP, EBIT, and Tobin's Q) and external performance indicators (Sales Growth, Coverage Ratio, DFL) are analysed. The method incorporates Fixed Effects (FE) panel regression models in STATA while controlling for firm size to mitigate performance heterogeneity due to scale. The correlation matrices and descriptive statistics consistently demonstrate positive relationships between the ESG components and financial performance. The VIF tests demonstrate confidence that multicollinearity does not impact coefficient estimates. The FE regression results indicate that ESG and its components exerted statistically significant and positive effects on internal and external performance measures. In particular, a firm's internal profitability, operational efficiencies, and market valuation are ESG-enhanced, while external sales growth, coverage ratios, and financial leverage are improved. These findings reinforce the critical role of sustainable business practices in emerging markets, such as Pakistan, where firms are increasingly exposed to global sustainability pressures and investor scrutiny. The results suggest that ESG integration can strategically drive financial resilience and enhance long-term competitiveness. This study contributes to the growing body of literature by providing empirical evidence from a developing market context and highlighting the importance of ESG adoption for stakeholders, including managers, regulators, and investors.
