چکیده

هدف تحقیق حاضر بررسی کارآیی انارکاران شهرستان خاش با استفاده از دو روش تحلیل پوششی داده­ ها و تحلیل فراکارآیی بود. اطلاعات مورد نیاز از طریق تکمیل پرسشنامه از انارکاران شهرستان خاش جمع‏ آوری شد. نتایج تحقیق نشان داد که میانگین سطح کارآیی فنی در شهرستان خاش در مدل با فرض بازده ثابت نسبت به مقیاس 46/0 و در مدل بازده متغیر نسبت به مقیاس 68/0 است و بین باغ‏های مورد بررسی، تفاوت آشکار در سطح کارآیی فنی وجود دارد، که مهم‌ترین علت آن ناکارآمدی در نحوه مدیریت استفاده از نهاده‌هاست. دامنه سطوح کارآیی در رهیافت فراکارآیی نیز بین 08/0 تا 86/6 درصد به‏دست آمد، که نشان‏دهندة تفاوت بسیار زیاد بین باغ‏ های انار در نمونه مورد بررسی به ‏لحاظ میزان مصرف نهاده‏ هاست. همچنین، نتایج رتبه‌بندی باغ‏ های انار با استفاده از رهیافت فراکارآیی با فرض نهاده‌گرا نشان داد که رتبه باغ‏های ناکارآ مشابه تحلیل پوششی داده­ هاست. از این ‏رو، توصیه می ­شود که با مدیریت صحیح و تخصیص بهینه نهاده‌های مورد استفاده در فرآیند تولید انار و حمایت ارگان ‏های مربوط، امکان افزایش و بهبودکارآیی تولیدکنندگان انار فراهم آید.

چکیده [English]

This study aimed at investigating the efficiency of pomegranate growers in Khash County of Iran using two methods of data envelopment analysis (DEA) and super-efficiency analysis. The required information was collected by completing a questionnaire from pomegranate growers in the county. The study results showed that the average level of technical efficiency in the model assuming constant return to the scale (CRS) was 0.46 and in the model assuming variable return to the scale (VRS) was 0.68; and there was a clear difference in the level of technical efficiency between the studied gardens. The most important reason is the inefficiency in how to manage the use of inputs. The range of efficiency levels in the super-efficiency model was estimated 0.08 to 6.86 percent, indicating a great difference between pomegranate gardens in terms of input consumption. The results of ranking pomegranate gardens using the super-efficiency approach with input-oriented assumption showed that the ranking of inefficient gardens was similar to that of the data envelopment analysis. Therefore, proper management and optimal allocation of inputs used in the pomegranate production process as well as the support of relevant agencies are recommended to increase and improve the efficiency of pomegranate producers.
