چکیده مقاله :
هدف این پژوهش، بررسی رابطه بین ابعاد حاکمیت شرکتی و مدیریت سود در شرکتهای پذیرفته شده در بورس اوراق بهادار تهران طی سالهای 1386-1381 می باشد. با روش نمونه گیری حذفی و با اعمال شرایط انتخاب نمونه، تعداد 40 شرکت بعنوان نمونه آماری انتخاب گردید. نتایج آزمون تفاوت میانگین نشان داد که : 1- شرکتهایی که دارای حاکمیت شرکتی کافی بوده اند ( خواه اینکه دارای حاکمیت شرکتی قوی یا ضعیف باشند) اقلام تعهدی اختیاری کمتری دارند یعنی در اینگونه شرکتها، مدیریت سود کمتر اتفاق می افتد. 2- شرکتهایی که دارای حاکمیت شرکتی کافی می باشند، در سطوح یکسان توانایی حاکمیت شرکتی نیز دارای اقلام تعهدی اختیاری کمتری هستند. 3- شرکتهای با حاکمیت شرکتی ضعیف نسبت به شرکتهای با حاکمیت شرکتی قوی، لزوما اقلام تعهدی اختیاری بیشتری ندارند. بطور کلی، نتایج بیانگر آنست که کفایت حاکمیت شرکتی، نسبت به توانایی حاکمیت شرکتی با مدیریت سود ارتباط معناداری دارد. بدین ترتیب نتایج گویای این مطلب است که کفایت حاکمیت شرکتی یکی از عوامل تعیین کننده موثر بر مدیریت سود است.
This study aims to investigate the relationship between corporate governance dimensions and earnings management in Tehran Stock Eechange over 2002-2007. We have selected 40 companies as the research sample after applying samplying techniques and deleting some companies. The results of the mean difference test showed that discretionary accruals are lower for the firms that had good performance in the past regardless of whether the corporate governance levels were strong or weak .We also found that discretionary accruals are lower for such firms after controlling the strength of corporate governance. Furthermore, we found that firms with weak governance may not necessarily have low discretionary accruals compared to the firms with strong governance. On the whole, the results support the conclusion that it is the adequacy rather than the strength of corporate governance that is associated with discretionary accruals. Thus, the results show that the adequacy of corporcete governance has a significant correlation with earnings management.
