چکیده

بهترین راه جهت افزایش تولید محصولات کشاورزی، بهبود کارایی و بهره­وری است. در این مطالعه کارایی فنی و رشد بهره­وری عوامل تولید چغندرقند در استان­های عمده تولیدکننده بر مبنای روش تحلیل پوششی داده­ها طی دوره زراعی 84-1383 تا 94-1393 بررسی شد. نتایج نشان داد که استان­های سمنان، فارس، قزوین، مرکزی و چهارمحال بختیاری فاقد کارایی فنی بوده و بیشترین مصرف غیربهینه در نهاده­ها مربوط به نهاده سم با 166 درصد ناکارایی در استان چهارمحال و بختیاری می­باشد. به عبارت دیگر مصرف سم می­تواند تا بیش از یک دوم در این استان کاهش یابد. تحلیل رشد بهره­وری نشان­دهنده رشد کاهشی هفت درصد در استان­های مورد مطالعه بود و فقط استان­های خراسان جنوبی و خراسان شمالی در طول دوره مطالعه دارای رشد بهره­وری به ترتیب چهار و شش درصد بوده­اند. بررسی ضریب همبستگی بین رشد بهره­وری و اجزای آن بیان‌گر ارتباط مثبت و معنی­دار (در سطح 5 درصد) بین رشد بهره­وری و تغییرات فناوری بود. با توجه به نتایج به‌دست آمده، دو استان خراسان جنوبی و خراسان شمالی هم از لحاظ کارایی و هم رشد بهره­وری در وضعیت بهتری قرار دارند. لذا مطالعه شیوه­های مدیریتی و استفاده از دانش بومی موجود در این دو استان، می­تواند منجر به معرفی الگویی جهت بهبود کارایی تولید چغندرقند در کشور گردد.

چکیده [English]

The best way to increase crop production is to improve efficiency and productivity. In this study, the technical efficiency and productivity growth of sugar beet production factors in major produced provinces were estimated using data envelopment analysis (DEA) method for the period of 2004-05 to 2014-15. Results showed that Semnan, Fras, Qazvin, Markazi, Chaharmahal and Bakhtiari had no technical efficiency and the most non-optimal input usage was related to pesticide with 166% inefficiency in Chaharmahal and Bakhtiari province. In the other words, pesticide usage can be reduced to more than half in this province. Productivity growth analysis showed a 7% decrease in growth in studied provinces and only Southern Khorasan and North Khorasan provinces had productivity growth of 4 and 6%, respectively. The correlation coefficient between productivity growth and its components showed a positive and significant (P<0.05) relationship between productivity growth and technological changes. According to the results, Southern Khorasan and North Khorasan provinces were in better position in terms of efficiency and productivity growth. Therefore, the study of management practices and the use of indigenous knowledge in these provinces can lead to the introduction of a model to improve the sugar beet production efficiency in the country.
