| چکیده | ||
| چغندرقند یکی از مهمترین محصولات زراعی در استان خراسان رضوی است، که نقش بسزایی در اقتصاد این منطقه دارد. لذا بررسی کارایی این محصول مهم به نظر میرسد. برای تحلیل اطلاعات از دو روش تحلیل پوششی دادهها و تحلیل مرزی تصادفی استفاده شد. دادههای مورد نیاز از طریق تکمیل پرسشنامه در سه شهرستان چناران، نیشابور و قوچان از 190 بهرهبردار چغندرقند در سال زراعی 91-1390 جمع آوری شد. نتایج مدل تحلیل مرزی تصادفی نشان داد که، کارایی فنی در شهرستانهای چناران، نیشابور و قوچان به ترتیب 65، 68 و 60 درصد میباشد. اما نتایج مدل تحلیل پوششی دادهها نشان داد، چناران بیشترین کارایی مقیاس را با مقدار 76 درصد به خود اختصاص داده است و نتایج مشابه برای نیشابور و قوچان به ترتیب 61 و 58 درصد بدست آمد، لذا نتایج هر دو مدل حاکی از آن است که پتانسیل زیادی در جهت افزایش و بهبود کارایی در منطقه مورد مطالعه وجود دارد. همچنین 73 تا 79 درصد از مزارع چغندرقند مورد بررسی در حالت بازده صعودی نسبت به مقیاس عمل کردهاند. لذا مصرف بیشتر نهادهها جهت افزایش تولید و درآمد زارعین تصمیم مناسبی میباشد، تا از این راه افزایش تولید و در نتیجه بهبود و افزایش کارآیی حاصل شود. | ||

| چکیده [English] | ||
| Sugar beet is one of the most important crops in Khorasan Razavi, Iran, which plays an important role in the economy of this province. So, it seems to be important to study the efficiency of the crop. To analyze the sugar beet efficiency information, two methods including data envelopment analysis (DEA) and stochastic frontier analysis (SFA) methods were used. Required data were collected from 190 sugar beet growers in Chenaran, Neyshabour and Ghochan cities by filling questionnaire in 2011-12 growing season. The results of SFA method showed that the technical efficiencies in Chenaran, Neyshabour and Ghochan were 65, 68, and 60%, respectively. However, the results of DEA method showed that the highest technical efficiency (76%) was found in Chenaran followed by Neyshabour (61%) and Ghochan (58%). Therefore, results obtained from the both models indicate that there is a great potential for efficiency improvement in the province. Also, 73-79% of sugar beet fields were performing in ascending state. In conclusion, an increase in input consumption is a proper decision to improve both production and farmers’ income which also improves the efficiency. | ||
