چکیده مقاله :
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.
The aim of this study was to calculate inputs' productivity and production elasticity in industrial farms in Chaharmahal and Bakhtaran province. The random sampling method is simple and the sample size is determined based on the Cochran formula of 86 dairy farms. Data were collected using a questionnaire and a census questionnaire. MIDAS regression model is used to analyze the data. To measure the traction and productivity of production institutions, the transcendental production function, as well as the fit of the model and the variables are meaningful, were used, respectively, from the F and t statistics. The results of this study indicate that the final productivity of the last breeder, labor force, drug and health services and consumption of concentrate in the tested dairy farms is positive, but the final consumption of fuel and fodder and crude oil is negative. Also, for 26.4% of dairy farms, the total factor productivity is less than one, and these dairy farms are at a disadvantage.
