Exploring the Relationship between Corporate Governance, Corporate Social Responsibility and Financial and Non-Financial Reporting: A Study of Large Companies in Greece

Academics and professionals alike are highly interested in Corporate Social Responsibility (CSR), Corporate Governance (CG), environmental, social, and governance (ESG) and corporate non-financial reporting (CNFR) and how they can improve a brand’s reputation, financial efficiency, and sustainability within businesses and organisations. The main objective of our study was to examine whether the financial data of large companies can be correlated with the data in their non-financial reports and provide information on the level of corporate governance and corporate responsibility and to examine the correlation between them. For this purpose, we conducted research by examining the 100 largest companies in Greece, over a period of 3 years, collecting both financial and non-financial data from their official reports. Using appropriate quantitative tools such as similarity, classification and econometric methods (stepwise method and panel least-squares method), the correlations between the data for CSR, CG and non-financial actions and key financial performance ratios are evaluated. Our research has revealed a strong link between financial performance and ESG actions of large companies and, in particular, we demonstrated the positive correlation of CSR performance with their total assets and whether they are listed on the stock exchange, and of CG with CSR and EBITDA. This study adds to the existing academic discourse on the relationship between financial and non-financial information of corporations in the areas of Corporate Responsibility and Governance and provides a valuable way to assess the decisions of businesses.
