บทคัดย่อ งานวิจัยนี้มีวัตถุประสงค์
เพื่อศึกษาอิทธิพล คุณลักษณะของผู้บริหาร คณะกรรมการบริษัท คณะกรรมการตรวจสอบ และคุณภาพงานสอบบัญชี
ต่อการทุจริตทางบัญชีของบริษัทที่จดทะเบียนในตลาดหลักทรัพย์แห่งประเทศไทย
โดยมีกลุ่มตัวอย่างเป็นบริษัทที่มีข่าวการกล่าวโทษการทุจริตทางบัญชีบนเว็บไซด์ของคณะกรรมการกำกับหลักทรัพย์และตลาดหลักทรัพย์
ระหว่างปี พ.ศ. 2552-2567 โดยมีกลุ่มตัวอย่างรวมทั้งสิ้นเป็นจำนวน 122 ชุดข้อมูล
(Firm-Year) ซึ่งจำแนกเป็นบริษัทที่มีข่าวการทุจริตจำนวน 61 ชุดข้อมูล
และกลุ่มตัวอย่างที่ไม่มีการทุจริตทางบัญชี จำนวน 61 ชุดข้อมูล ผลการศึกษาพบว่า
คุณลักษณะของผู้บริหาร เรื่องอายุและระดับการศึกษาของผู้บริหารมีอิทธิพลเชิงลบต่อโอกาสในการทุจริตทางบัญชี
ในขณะปัจจัยค่าตอบแทนของผู้บริหารยังคงเป็นแรงจูงใจให้ผู้บริหารทำการทุจริตเพิ่มขึ้นได้
สำหรับบทบาทของคณะกรรมการบริษัทพบว่า สัดส่วนของคณะกรรมการอิสระนั้น
มีอิทธิพลเชิงลบต่อโอกาสในการเกิดการทุจริตทางบัญชีอย่างมีนัยสำคัญ
ในขณะที่ความถี่ในการประชุมของคณะกรรมการกลับสะท้อนถึงการเพิ่มขึ้นของการทุจริตทางบัญชี
นอกจากนั้นแล้วการมีคณะกรรมการตรวจสอบยังส่งเสริมประสิทธิภาพการกำกับดูแลกิจการและลดทอนการทุจริตทางบัญชีเช่นกัน
โดยการมีคณะกรรมการตรวจสอบจำนวนมากและวาระดำรงตำแหน่งยาวนานจะทำให้มีโอกาสในการเกิดการทุจริตทางบัญชีลดลงได้อย่างมีนัยสำคัญ
อย่างไรก็ตามเป็นที่ประหลาดใจ
การมีคณะกรรมการตรวจสอบที่มีความรู้ทางด้านบัญชีและการเงินในสัดส่วนที่สูงขึ้นกลับมีอิทธิพลต่อการเกิดการทุจริตเพิ่มขึ้นได้
นอกจากกลไกจากภายในแล้วนั้น
การตรวจสอบโดยผู้สอบบัญชีภายนอกยังมีส่วนสำคัญต่อการทุจริตทางบัญชีเช่นกัน
โดยสำนักงานสอบบัญชีขนาดใหญ่ (BIG
4) ส่งผลให้มีโอกาสเกิดการทุจริตลดลงอย่างมีนัยสำคัญ
อย่างไรก็ตามปัจจัยค่าธรรมเนียมการสอบกลับสะท้อนถึงโอกาสของการทุจริตทางบัญชีที่เพิ่มขึ้น |

ABSTRACT This study aims to
examine the influence of executive characteristics, board of directors, audit
committee, and audit quality on accounting fraud among firms listed on the
Stock Exchange of Thailand. The sample comprises firms that were publicly
accused of accounting fraud on the Securities and Exchange Commissions
website between 2009 and 2024, totaling 122 firm-year observations, of which
61 represent fraud cases and 61 represent non-fraud cases. The findings
reveal that executive age and educational level are negatively associated
with the likelihood of accounting fraud, while executive compensation remains
a motivating factor that increases the probability of fraudulent behavior.
With respect to board characteristics, a higher proportion of independent
directors significantly reduces the likelihood of accounting fraud, whereas
board meeting frequency is positively associated with fraudulent activity.
Moreover, the establishment of an audit committee enhances governance
effectiveness, as a greater number of committee members and longer tenure are
both significantly linked to reduced fraud risk. However, it is surprising
that higher levels of financial and accounting expertise within the audit
committee are associated with an increased risk of fraud. Apart from internal
mechanisms, the role of the external audit is equally critical. Evidence
suggests that the appointment of Big 4 audit firms substantially lowers the
probability of accounting fraud, while audit fees tend to signal a higher
risk of fraudulent practices. |
