| چکیده | ||
| آب یکی از ارزشمندترین منابع طبیعی است که به عنوان یکی از نهاده های اصلی تولید محصولات کشاورزی، جایگاه خاصی در تأمین امنیت غذایی و توسعه پایدار بخش کشاورزی دارد. تعیین قیمت واقعی مبتنی بر ارزش اقتصادی آب، به عنوان یکی از مهمترین ابزارهای اقتصادی مدیریت تقاضای آب، نقش مهمی در تخصیص بهینه منابع آب بین مناطق و محصولات مختلف خصوصاً در شرایط بحران کم آبی دارد. بر این اساس در این مطالعه ارزش اقتصادی نهاده آب با استفاده از تخمین تابع تولید محصول چغندرقند در استان گلستان برآورد گردید. به این منظور، ابتدا فرم تابعی مناسب و منطبق بر فناوری تولید این محصول براساس معیارهای اقتصادسنجی با استفاده از اطلاعات مربوط به 166 چغندرکار استان گلستان در سال زراعی 1400-1399 با روش نمونهگیری طبقهبندی شده تصادفی انتخاب شد، نتایج این مطالعه نشان داد که تابع تولید ترانسلوگ بهترین فرم تابعی میباشد. پس از تخمین تابع تولید، ارزش اقتصادی نهاده آب، معادل 20690 ریال به ازای هر مترمکعب برآورد شد. نتایج همچنین نشان داد که مبلغ پرداختی کشاورزان به عنوان آببها (3490 ریال) تقریبا حدود 17 درصد ارزش اقتصادی آب است که با قیمت واقعی آب اختلاف زیادی دارد. بنابراین پیشنهاد میگردد با حذف تدریجی اختلاف آببهای پرداختی کشاورزان با ارزش اقتصادی آب، قیمت واقعی آب اخذ گردد. | ||

| چکیده [English] | ||
| Water is one of the most valuable natural resources that, as one of the main inputs for the production of agricultural products, has a special place in providing food security and sustainable development of the agricultural sector. Determining the real price based on the economic value of water, as one of the most important economic tools of water demand management, plays an important role in the optimal allocation of water resources between different regions and products, especially under water shortage crisis. In this regard, in the economic value of water input was estimated using the production function estimation of sugar beet in Golestan province in the present study. For this purpose, at the beginning, a suitable functional form was selected according to the production technology of this product based on econometric criteria using information related to 166 sugar beet growers in Golestan province in the crop season of 2020-21 with a random stratified sampling method. Results of this study showed that the translog production function is the best functional form. After estimating the production function, the economic value of water input was estimated as 20,690 Iranian Rials per m-3. The results also showed that the amount paid by growers as water price (3490 Rials) is approximately 17% of the economic value of water, which is very different from the actual price of water. Therefore, it is suggested to obtain the real price of water by gradually eliminating the difference between the water price paid by growers and the economic value of water. | ||
