چکیده مقاله :
Khuzestan Province, especially Karun County, is one of the main pillars of date production in Iran. According to the limitations of date palm production in this county, optimal production management, and the efficient use of production inputs are required. The main goal of this study was to calculate the technical efficiency of date palm cultivators’ management in the whole Karun, as well as the cities in this County including four cities, using a non-parametric approach such as the Data Envelopment Analysis (DEA) method. 200 date palm cultivators were selected as samples across the region, 50 date palm cultivators from each city in April 2017 till February 2018. The results showed that Rabie and Shirin-Shahr cities have the most efficient and non-efficient date palm cultivators’ management, respectively. The average efficiency under constant returns to scale assumption was 100 percent, the variable returns to scale input-oriented and output-oriented in Rabie city were 100 and 100 percent, and in Shirin-Shahr city, the average efficiency under constant returns to scale was 97.56 percent, the variable returns to scale input-oriented and output-oriented were 98.69 and 98.04 percent, respectively. In Karun County, the average efficiency under constant returns to scale was 96.62 percent, the variable returns to scale input-oriented and output-oriented efficiencies were 98.66 and 97.57 percent, respectively. In this region, cultivators’ management efficiency can be increased by increasing the awareness and skills of date palm cultivators and educating them in terms of optimal use of inputs.
استان خوزستان و بویژه شهرستان کارون در این استان، یکی از قطبهای اصلی تولید خرما درکشور ایران میباشد. نظر به محدودیت عوامل تولید خرما در این شهرستان، لازم است مدیریت بهینهای بر تولید این محصول و بهکارگیری نهادههای تولید صورت گیرد. هدف اصلی تحقیق حاضر، محاسبه کارایی فنی مدیریت نخلکاران همه شهرستان کارون و همچنین به تفکیک شهرهای این شهرستان، مشتمل بر چهار شهر، با استفاده از روش ناپارامتری تحلیل پوششی دادهها میباشد. 200 نخلکار از کل منطقه، از هر شهر50 نخلکار، با بازه مطالعه بین فروردین 1396 تا زمستان 1396 تعیین گردید. نتایج تحقیق نشان داد که شهر ربیع و شیرین شهر به ترتیب کاراترین و ناکارآمدترین مدیریت نخلکاران را دارا هستند. برای شهر ربیع، میانگین کارایی با مقیاس ثابت 100 درصد، کارایی با مقیاس متغیر با رویکرد حداقل کردن نهاده و حداکثر کردن ستاده، 100 و100 درصد و برای شیرین شهر، میانگین کارایی با مقیاس ثابت 56/97 درصد ، کارایی با مقیاس متغیر با رویکرد حداقل کردن نهاده و حداکثر کردن ستاده به ترتیب برابر 69/98 و 04/98 درصد به دست آمده است. در شهرستان کارون، میانگین کارایی با مقیاس ثابت 62/96 درصد، کارایی با مقیاس متغیر با رویکرد حداقل کردن نهاده و حداکثر کردن ستاده به ترتیب برابر 66/98 و 57/97 درصد به دست آمد. در این منطقه، با افزایش آگاهی و مهارت نخلکاران و آموزش آنها در زمینه استفاده بهینه از نهادهها، میتوان کارایی نخلکاران را افزایش داد.
