موضوع مقاله حاضر«مطالعه تاثير نوع صنعت بر روي روابط حاكميت شركتي و بهره وري شركت ها» مي باشد. در اين پژوهش به بررسي رابطه بين نوع فعاليت صنعت و حاكميت شركتي و بهره وري كل با حضور و بدون حضور متغيرهاي كنترل پرداخته شده است. قلمرو مكاني تحقيق شامل شركت هاي پذيرفته شده دربورس اوراق بهادار تهران مي باشد. قلمرو زماني نيز فاصله بين سال هاي 1382تا1390 را در برمي گيرد. تحقيق شامل يك متغير مستقل (نوع صنعت)، و دو متغير وابسته (حاكميت شركتي و بهره وري كل) و متغيرهاي كنترل مي باشد. در فرضيه اول رابطه بين تمركز مالكيت و بهره وري كل و در فرضيه دوم رابطه بين اندازه هيات مديره و بهره وري كل و در فرضيه سوم رابطه بين نوع فعاليت صنعت و بهره وري كل در مدل تحقيق وارد شده و معناداري آنها بررسي-گرديد. نتيجه حاصل از آزمون نشان داد كه بين تمركز مالكيت و بهره وري كل رابطه معنادار منفي و بين اندازه هيات مديره و بهره وري كل رابطه معنادار مثبت و بين نوع فعاليت صنعت و بهره وري كل رابطه معنادار منفي وجود دارد
