Key objective of this study was to measure the role of CSR on corporate financial performance in Bangladesh. It has measured the performance of all (30 in 2015) listed private commercial banks (PCBs) of Bangladesh. Those organizations were studied for a ten-year period ranging 2011-2020. The statistical techniques of analyzing panel data especially OLS, random effect, fixed effect, GMM and dynamic GMM methods have been used. The econometric model has been developed where CSR expenditure is a dependent variable and financial performance indicators of the firm (e.g. ROA, ROE, TobinQ, EPS and market price of share) are considered as independent variables. Data analyses show that CSR has a positive effect on the corporate financial performance in Bangladesh.
