چکیده

هدف: راهبرد رشدِ تنوع‌بخشی یکی از راهبرد‌های سطح شرکت است. در مدیریت راهبردی، تصمیم‌گیری درباره جهت، نوع و نحوه رشد بنگاه، به تجزیه و تحلیل تأثیرات ایجاد شده بر تغییرات عملکرد مالی نیاز دارد. تأثیر تنوع بر عملکرد مالی بنگاه‎های اقتصادی همچنان موضوع مناقشه‎برانگیزی است. هدف این پژوهش بررسی تأثیر تنوع‎بخشی سبد کسب‎وکار بر عملکرد مالی است.
روش: در پژوهش حاضر به بررسی 37 شرکت مادر پذیرفته شده در بورس طی 5 سال پرداخته‌ایم و با استفاده از رگرسیون داده تابلویی، رابطه غیرخطی بین شاخص هرفیندال به‎عنوان شاخص تنوع و بازده دارایی‎ها به‎عنوان شاخص عملکرد را تحلیل کرده‎ایم. از متغیرهای اندازه، رشد شرکت و بدهی، به‎عنوان متغیرهای کنترل استفاده شده است.
یافته‎ها: آماره F مدل و ضریب تعیین مدل به‎ترتیب مقادیر مناسب 000000/0 و 889855/0 را به‎دست آورده‎اند و بر اساس آماره t بین تنوع و بازده دارایی‎ها رابطه شایان توجهی وجود دارد.
نتیجه‎گیری: شواهد به‎دست‎آمده حاکی از آن است که رابطه بین تنوع‌بخشی و عملکرد غیرخطی است و تنوع باعث می‎شود ارزش و کاهش عملکرد تخریب ‌شود.
