چکیده مقاله :

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.

چکیده انگلیسی:

The purpose of this study was to investigate the role of efficiency in the transmission of climate and price shocks on farmers' behavior. The hypothesis of this study is that efficient farmers in the agricultural sector are more resilient and less vulnerable to climate and price shocks. In order to test this hypothesis, data envelopment analysis approach and positive math planning model were used. Data needed for this purpose were collected from the Agricultural Jihad questionnaires in Razan township, north of Hamedan province. The findings indicate that, due to the effects of climate change, farmers' groups are less effective than inefficient farmers and have more resistance. Also, farmers are less effective than price changes, which reflect the stable situation of this group of farmers in relation to these shocks. Therefore, it can be inferred that moving towards a productive boundary can be a means to reduce the impact of climatic hazards, markets and fluctuations in agricultural production in the studied area.
