Abstract:

This study examines the factors that influence the publication of sustainability reports (SR), using a sample of 297 Portuguese companies, mainly unlisted. To identify the determinants of SR, a binary logistic regression was conducted with SR disclosure as the dependent variable. Explanatory variables included sector, size, profitability (ROA), sales growth rate, and liquidity. The results indicate a positive and significant relationship between company size and SR disclosure: larger companies are 1.5 times more likely to disclose SR, supporting the legitimacy theory that larger companies use SR to legitimise their activities and respond to stakeholder pressure. This effect is especially strong for companies in the industry and raw materials sectors. The other explanatory variables did not show a statistically significant effect on SR disclosure.
