Özet:

The study examined corporate governance and corporate sustainability impact on the performance of South African listed companies. Data retrieved from 30 companies for the period 2010-2020 was analysed using panel fully modified ordinary least squares (FMOLS) and dynamic ordinary least square (DOLS) methods. Dependent variables were grouped into the Accounting-based approach and the Market-based approach. Explanatory variables were also grouped into Corporate Governance and Accounting ratios. Findings revealed a strong relationship between corporate governance and company performance. This was substantiated by the result from Board gender diversity, which revealed both positive and negative relationships that were significant under both approaches. Directors’ remuneration revealed a positive but insignificant relationship under both approaches, while Board size revealed a negative relationship under both approaches. Further findings also revealed a strong relationship between corporate sustainability performance and company performance. This was established by the results from the ESG and ROA and ROE, which revealed negative but significant relationships under the first approach and became positive and significant under the second approach. Lastly, a strong relationship between corporate governance and corporate sustainability performance was revealed as shown between ESP and directors’ remuneration and a negative but significant relationship with board size and gender diversity. A cross-country based investigation to ascertain whether the same results can be achieved should be carried out.
