چکیده

هدف این مطالعه بررسی مزیت نسبی تولید چغندرقند در ایران بود. چغندرقند ازجمله محصولات اساسی است که یکی از منابع مهم تأمین انرژی به شمار می‏آید. در این مطالعه اهمیت محصول چغندرقند (منبع تولید شکر) در الگوی غذایی خانوارهای ایرانی و نوسانات قیمت این محصول و تقاضای زیاد مصرف کننده، سودآوری اجتماعی محصول چغندرقند و اثرات سیاست‏های دولت و تأثیر تنگناهای بازار داخلی روی تولیدکننده با استفاده از روش ماتریس تحلیل سیاستی در ایران برای سال زراعی 86-1385 مورد بررسی قرار گرفت. آمار و اطلاعات مورد نیاز این مطالعه از مطالعات اسنادی به‏دست آمده است. نتایج ماتریس تحلیل سیاستی نشان دهنده وجود مزیت نسبی در تولید محصول چغندرقند در ایران است(55/0=DRC). از سوی دیگر ضریب حمایت اسمی بر محصول نشان‏دهنده وجود مالیات غیرمستقیم بر تولید محصول چغندرقند (77/0=NPC) است، ضریب حمایت اسمی بر نهاده نشان‏دهنده وجود مالیات غیرمستقیم برای نهاده‏های قابل تجارت (55/2=NPI) می‎باشد و ضریب حمایت مؤثر نشان از آن دارد که مالیاتی که دولت به‏صورت غیرمستقیم بر محصول چغندرقند در نظرگرفته است بیش از یارانه‏ای است که جهت نهاده‏ها پرداخت کرده است. لذا دولت باید در جهت اصلاح و بهبود سیستم پرداخت یارانه به نهاده‏ها به‏نحوی که موجب افزایش کارایی سیستم شود برنامه‏ریزی نماید.

چکیده [English]

The main objective of this study is to investigate the comparative advantage for Sugar beet production in Iran. Sugar beet is one of the main crops which is considered as an important resource for energy supply. The importance of sugar beet (as a sugar source) in Iranian household food basket, price fluctuation and consumers' demand for sugar beet, social profitability and the impact of government polices and national market limitations on sugar beet growers was investigated using Policy Analysis Matrix (PAM) method in Iran for 2006-2007 growing season. The data of the study was obtained from documentary studies. The results of the Policy Analysis Matrix showed comparative advantage in sugar beet production in Iran (DRC=0.55). The nominal protection coefficient of  the product also showed an indirect tax on sugar beet production (NPC=0.77), while Nominal protection coefficient of input indicates an indirect tax for inputs (NPI=2.55). However, effective protection coefficient proves that the indirect tax for sugar beet crop exceeds the corresponding subsidies paid by government to inputs. Therefore, government should plan to reform and to improve the inputs subsidy system to raise the efficiency.
