چکیده
آب یکی از سه منبع طبیعی مهم در کنار خاک و هوا است. این منبع ارزشمند در معرض تهدید شدید تغییرات آب و هوایی و تقاضای افزایش جمعیت در دهه‌های اخیر قرار دارد. از آنجایی که یک منبع غیرقابل جایگزین است، کمبود آن به دلیل هزینه بالای دسترسی به منابع آب جدید تشدید شده است. آب به عنوان یک کالای عمومی در نظر گرفته می‌شود که باید توسط دولت ها برای بخش های مختلف مصرف کننده تامین و توزیع شود. در واقع این موضوع باعث کمبود بیشتر منابع آب می شود. در این پژوهش به منظور بررسی و تحلیل مدل‌های قیمت‌گذاری آب، داده‌های مربوط به مصارف آب برای دوره زمانی 1392 تا 1402 استخراج و از مدل رگرسیونی داده‌های ترکیبی و مقایسه ضرایب تعیین با رویکرد آزمون وونگ استفاده شده است. نتایج پژوهش حاکی از آن است که قیمت‌گذاری آب تابعی از مولفه‌های مختلف خرد و کلان است. تغییر در هریک از این مولفه‌ها از جمله نیروی کار، انرژی، سرمایه و حجم آب مصرفی منجر به تغییر هزینه‌های مرتبط می‌گردد. با توجه به ضرایب تعیین تعدیل شده، تابع کاپ داگلاس بالاترین قدرت توضیح‌دهندگی را نسبت به دیگر مدل‌ها دارد. در نهایت، مطابق با آزمون وونگ، اختلاف ضریب تعیین تعدیل شده مدل کاپ داگلاس در برآورد قیمت‌گذاری آب نسبت به دیگر مدل‌ها معنادار است.

چکیده English

Water is one of the three important natural resources along with soil and air. This valuable resource is under severe threat from climate change and population growth in recent decades. Since it is an irreplaceable resource, its scarcity has been exacerbated by the high cost of accessing new water resources. Water is considered a public good that must be provided and distributed by governments to different consumer sectors. In fact, this issue causes further scarcity of water resources. In this study, in order to examine and analyze water pricing models, data related to water consumption for the period 1392 to 1402 were extracted and a mixed data regression model and coefficients of determination were compared using the Wong test approach. The results of the study indicate that water pricing is a function of various micro and macro components. Changes in each of these components, including labor, energy, capital, and water consumption volume, lead to changes in related costs. According to the adjusted coefficients of determination, the Cop-Douglas function has the highest explanatory power compared to other models. Finally, according to the Wong test, the difference in the adjusted coefficient of determination of the Cop-Douglas model in estimating water pricing compared to other models is significant.
