This study investigates the impact of women directors (WOB), independent directors (BIND), board size (BSIZE), and Sustainability Committee (SC) on Firm Financial Performance (FFP) with a unique mediation of Corporate Sustainability Practices (CSP) in a stratified random sample of 255 non-financial Pakistani listed companies from 2012 to 2016. By using the Ordinary Least Squares (OLS) and OLS with Panel Corrected Standard Errors (PCSE), it is revealed that BIND and large BSIZE are the significant positive predictors of CSP. Besides a positive association between CSP and FFP (Tobin's Q and ROE), it is also noted that CSP positively mediates the nexus of BIND and BSIZE with FFP. However, WOB and SC have no significant or positive effect on CSP and FFP. Moreover, the significant positive effect of BIND slightly decreases with its increase beyond a certain limit in relation to CSP and FFP. The study provides several contributions to the literature and practice.

本研究通过对企业可持续发展实践 (CSP) 的独特调解，调查了女性董事 (WOB)、独立董事 (BIND)、董事会规模 (BSIZE) 和可持续发展委员会 (SC) 对公司财务绩效 (FFP) 的影响。对 2012 年至 2016 年 255 家非金融类巴基斯坦上市公司的分层随机样本。通过使用普通最小二乘法 (OLS) 和具有面板校正标准误差 (PCSE) 的 OLS，发现 BIND 和大 BSIZE 是显着的正预测因子太阳能电池板。除了 CSP 和 FFP 之间的正相关（托宾 Q 和 ROE）外，还注意到 CSP 正向介导 BIND 和 BSIZE 与 FFP 的关系。然而，WOB 和 SC 对 CSP 和 FFP 没有显着或积极的影响。而且，BIND 的显着正效应相对于 CSP 和 FFP，随着其增加超过一定限度而略有下降。该研究为文献和实践提供了一些贡献。
