جدول داده- ستانده، روشی مناسب برای شناسایی بخش‌های کلیدی اقتصاد منطقه¬ای است. از جدول داده- ستانده ضرایب فزاینده تقاضا و عرضه استخراج می¬گردد که این ضرایب فزاینده قادر به محاسبه بخش‌های پیشرو طرف تقاضا و طرف عرضه و درنهایت محاسبه بخش‌های کلیدی هستند. ضرایب فزاینده¬ها را می‌توان به دو دسته ضرایب فزاینده ناخالص (سنتی) و ضرایب فزاینده خالص (ابتکار Oosterhaven, Stelder) تقسیم کرد. این مقاله ضرایب فزاینده ناخالص و خالص را برای استان مرکزی محاسبه نموده است. نتایج مقاله نشان می¬دهد در بحث منطقه¬ای (استان) ضرایب فزاینده ناخالص عملکرد مناسب‌تری نسبت به ضرایب فزاینده خالص دارند. ضرایب فزاینده خالص تنها فعالیت‌های اقتصادی را به دو گروه عرضه محور و تقاضا محور تقسیم می¬کند و بدین ترتیب ضرایب فزاینده خالص قادر به ساختن بخش‌های کلیدی استانی در ایران نیست؛ درحالی‌که ضرایب فزاینده ناخالص فعالیت‌های اقتصادی منطقه را در چهار گروه قرار داده و قادر به ساختن بخش‌های کلیدی است.
