چکیده

هدف از مطالعه حاضر، ارزیابی عملکرد تعاونی ها و واحدهای غیرتعاونی فعال پرورش میگو در منطقه گواتر شهرستان چابهار استان سیستان و بلوچستان می باشد. عملکرد این واحدها با استفاده از دو شاخص سودآوری و کارایی فنی بررسی شده است. سودآوری با استفاده از معیار درآمد ناخالص و کارایی فنی واحدها با استفاده از مدل های غیرپارامتریک BCC و سوپرکارایی به‌دست آمد. همچنین نوع بازده به مقیاس هر یک از بنگاه‌ها برآورد شد. داده‌ها از کل جامعه مورد بررسی (25واحد در سال88) جمع آوری گردید. نتایج مدل های کارایی نشان داد میانگین کارایی فنی با استفاده از مدلBCC 85% است، در حالی که تنها 25% از بنگاه های مورد بررسی کاملا کارا بودند. رتبه بندی حاصل از مدل سوپرکارایی نشان داد که تفاوت معنی داری بین کارایی واحدها وجود دارد. نتایج بررسی نشان داد که ناکارایی بنگاه ها ناشی از پایین بودن سطح مهارت های مدیریتی می باشد. به منظور افزایش کارایی انجام آموزش های ترویجی پیشنهاد گردیده است.

چکیده [English]

The purpose of this study is to assess the performance of shrimp cooperatives and non-cooperatives in Guatr district in Chabahar city of Sistan and Baluchistan province. To achieve the objective of study, profitability and efficiency indices were used. Data were collected from 25 shrimp farms. Technical efficiency was estimated by BCC and super efficiency models. The results of study revealed that all farms made profit. Moreover, the ranking of super efficiency models showed significant differences among efficiency levels of farms. Low level of efficiency was mainly related to poor management and rate of inputs utilization. Therefore, providing intensive extension services was recommended.
