چکیده

با توجه به ماهیت توأم با ریسک و عدم قطعیت بخش کشاورزی، مطالعه حاضر به منظور بررسی ضریب ریسک‌گریزی کشاورزان شهرستان اسفراین انجام شده است. در این راستا از جدیدترین روش ناپارامتریک محاسبه ضریب ریسک‌گریزی و با بهره‌گیری از مدل برنامه‌ریزی درجه دو (QP) استفاده شده است. بدین منظور داده‌های پانلی 100 کشاورز، طی 4 سال (1388- 1391) و برای 14 محصول جمع‌آوری شده است. نتایج مطالعه نشان داد اکثر کشاورزان منطقه مورد مطالعه دارای درجه ریسک‌گریزی بسیار زیاد و شدیداً ریسک گریز می‌باشند. حق بیمه اجتناب از ریسک کشاورزان نمونه مورد بررسی 303113 ریال به دست آمده است. همچنین متغیر سن تأثیر مثبت و سطح ثروت و تنوع کشت تأثیر منفی بر ضریب ریسک‌گریزی کشاورزان داشته است. با توجه به نتایج به دست آمده توسعه بیمه و سرمایه‌گذاری در زمینه بورس کالاهای کشاورزی به منظور کاهش ضریب ریسک‌گریزی پیشنهاد می‌شود.
