چکیده | ||
موفقیت در افزایش تولید بخش کشاورزی نیازمند اجرای سیاستهای درست و مدون جهت حمایت از تولیدکنندهگان است. اجرای علمی سیاستهای حمایتی نظیر تعیین خرید تضمینی برای محصول استراتژیک گندم میتواند اثرات مطلوبی بر تولید این محصول داشته باشد. با توجه به اهمیت این موضوع، هدف از پژوهش حاضر بررسی اثر سیاست خرید تضمینی بر بهرهوری تولید گندم در استان یزد برای دوره زمانی 95-1368 بود. برای محاسبه بهرهوری از شاخص مالمکوئیست و برای تحلیل سری زمانی از الگوی خودرگرسیونبرداری استفاده شد. نتایج تحقیق نشان داد که میزان بهرهوری برای گندم نزدیک به یک است. همچنین میزان بهرهوری بههمراه عملکرد گندم در کوتاهمدت رابطه مثبت و معنیداری با خرید تضمینی دارد، اما در بلندمدت تأثیر این سیاست کاهش مییابد. در نتیجه با توجه به آثار متفاوت خرید تضمینی بر بهرهوری گندم، پیشنهاد میشود کیفیت اجرای این سیاست مورد بازبینی قرار گیرد و همچنان ادامه یابد. | ||
