چکیده

پژوهش پیش رو به بررسی این موضوع می‎پردازد که تفاوت بین سطح افشای اختیاری قبل و بعد از واگذاری شرکتها، تنها از واگذارشدن آنها به بخش خصوصی ناشی می‎شود یا تغییراتی که بعد از واگذاری در ساختار مالکیت، نظام راهبری شرکتها و قوانین سازمان بورس به‎وجود میآید، این تفاوت را ایجاد میکند. برای این منظور از میان شرکتهای واگذار‌شده بین سال‌های 1381 تا 1388، 30 شرکت انتخاب شد و به‎کمک 96 گزارش سالانة هیئت‎مدیره به مجمع این شرکتها، نمره‎های افشای اختیاری آنها در سال‌های قبل و بعد از واگذاری محاسبه و بررسی شد. نتایج گویای آن بود که چهار متغیر نسبت مالکیت شخصی، نسبت مالکیت دولتی، نسبت اعضای غیرموظف هیئت‎مدیره و ساختار هدایتی یگانه، تأثیر معناداری بر سطح افشای اختیاری می‎گذارد، اما واگذاری شرکتها به بخش خصوصی، اثر چهار متغیر نام‎برده بر سطح افشای اختیاری را تشدید نمی‎کند.

چکیده [English]

This study examines the level of voluntary disclosure in Iranian companies. It is examined if the volume of voluntary disclosure is influenced by transferring a governmental company to private sector. To reveal the impact of privatization on the volume of the voluntary disclosure, a sample of 30 companies transferred from public to private sector since 2003 to 2010, is selected. This sample includes 96 Boards of Directors Reports. The results indicate that the four variables of private ownership, the proportion of state ownership, the proportion of outside board members and leadership structure have significant effects on the level of voluntary disclosure, but  transferring the governmental companies to private sector has not increased the positive effect of the above variables.
