This paper employs a CGI Index formulated from KING III and IV report to examine the link between corporate performance and quality of corporate governance (CG) and corporate social responsibility (CSR) of SA-REITs listed on the Johannesburg Stock Exchange (JSE). The CGI index is created from King III and IV. The empirical investigation using multiple correspondence analysis (MCA) reveals that corporate governance (CG) practices have a positive influence on firm performances measured by (such as total share return and return on assets). The results imply CG influences the firm performance of SA-REITs. The CSR index is created from the King reports, also the MCA was used, and CSR will likely improve SA-REITs performance by 13%.
