ملخص المقالة :
هدف این مطالعه بررسی نقش کارایی در انتقال شوکهای اقلیمی و قیمتی بر رفتار کشاورزان است. فرضیه مطالعه حاضر این است که بهره‌برداران کارای بخش کشاورزی در مقابل شوکهای اقلیمی و قیمتی وارده تابآوری بیشتری دارند و کمتر متضرر میشوند. به منظور تست این فرضیه، از رهیافت تحلیل پوششی داده ها و از الگوی برنامه ریزی ریاضی مثبت استفاده شد. اطلاعات مورد نیاز برای این منظور از پرسشنامههای جهاد کشاورزی شهرستان رزن، واقع در شمال استان همدان استخراج شد. یافتهها حاکی از آن است که بر اثر اعمال شوک اقلیمی، گروه‌های کشاورزان کارا نسبت به کشاورزان ناکارا کمتر تحت تاثیر قرار گرفته و مقاومت بیشتری دارند. همچنین کشاورزان کارا اثر‌پذیری کمتری نسبت به تغییرات قیمت دارند که نشان از وضعیت با ثبات این گروه از کشاورزان نسبت به این شوکها دارد. لذا این گونه استنباط می‌شود که حرکت به سمت مرز کارای تولید میتواند ابزاری برای کاهش اثر مخاطرات اقلیمی، بازار و نوسان تولید محصولات کشاورزی در سطح منطقه مورد مطالعه باشد.
