چکیده: (3136 مشاهده)
در دهه های اخیر در دشت همدان - بهار به دلیل کاهش سطح سفره آب زیرزمینی، اتخاذ راهکار مدیریتی مناسب جهت
بهره برداری بهینه از این منبع اهمیت فراوانی یافته است. در این رابطه مسئله اصلی ایجاد تعادل بین عرضه و تقاضای آب است. در ایجاد این تعادل، ارزش اقتصادی آب مانند قیمت هر نهادهی دیگر نقش تعیین کنندهی بر عهده دارد. به همین دلیل قیمت گذاری آب به عنوان یک روش غیر مستقیم برای استفاده کارا و پایدار از آب در بخش کشاورزی توصیه شده است. در این راستا هدف این پژوهش برآورد ارزش اقتصادی آب با استفاده از رهیافت اقتصاد سنجی فضایی است. این تحقیق با در نظر گرفتن این موضوع که چاههای کشاورزی با سایر چاههای مجاور از نظر منابع آب زیرزمینی ارتباط دارد، تلاش دارد به این سؤال پاسخ دهد که عامل مجاورت تا چه حد تابع تقاضای آب را تحت تأثیر قرار می دهد. ضریب همبستگی حاصل از تخمین توابع نشان داد، که کاربرد رگرسیون فضایی نسبت به روش رگرسیون کلاسیک برتری دارد. اطلاعات مورد نیاز در این تحقیق به صورت میدانی و با تکمیل پرسشنامه از کشاورزان در سال 1395 جمع آوری شده است. نتایج این تحقیق نشان داد که قیمت واقعی آب در تولید سیب زمینی برای هر متر مکعب 2040 ریال است. بنابراین برای ایجاد تعادل بین عرضه و تقاضای آب می توان از شکاف قیمت واقعی آب و قیمتی پرداختی توسط کشاورزان جهت اعمال سیاست قیمت گذاری آب در منطقه استفاده کرد.
