Thus, this study initially examines empirical evidence regarding financial statement fraud in line with the Fraud Diamond Theory in Thailand. It proposes to reflect factors of financial statement fraud that exist. The objectives of this study were 1) to analyze the factors of the Fraud Diamond Theory that influence financial statement frauds of listed companies in Thailand 2) to examine the effects of the Fraud Diamond Theory factors on the financial statements of listed companies in Thailand, and 3) to study the relationship between moderator variables, namely the size of the company and the risks of the industry, and the factors of the Fraud Diamond Theory influencing the financial statement fraud of listed companies on the Stock Exchange of Thailand.

Secondary data were collected from 371 listed companies on the Stock Exchange of Thailand during the 2015–2020 period. There were 1,855 observations in total. The research used descriptive statistics and logistic regression analysis to prove the research hypotheses. The results revealed that 11.48 percent of the samples had a high probability of financial statement fraud.
