ملخص المقالة :
هدف این پژوهش محاسبه بهره وری نهاده ها و کشش تولید در گاوداریهای صنعتی استان چهارمحال و بختیاری است. روش نمونه گیری تصادفی ساده است و حجم نمونه بر اساس فرمول کوکران معادل86 گاوداری تعیین شده است. داده ها به روش اسنادی و با استفاده از پرسشنامه جمع آوری شده است. برای تجزیه و تحلیل داد ها از مدل رگرسیون ترکیبی MIDAS بهره گرفته شده است. برای سنجش کشش و بهره وری نهادهای تولید، از تابع تولید ترانسندنتال و همچنین برای آزمون برازش مدل و معنی دار بودن متغیرها، به ترتیب از آماره های F و t استفاده شده است. نتایج پژوهش حاکی از آن است که بهره وری نهایی آخرین رأس گاوشیری، نیروی کار، دارو و خدمات بهداشتی و مصرف کنسانتره در گاوداری های مورد بررسی مثبت است ولی بهره وری نهایی مصرف سوخت و علوفه و مواد خشبی منفی است، همچنین برای 4/26 درصد گاوداریها بهره وری کل عوامل تولید کمتر از یک است و این گاوداری ها با زیان مواجه بوده اند.
