چکیده

به‌دلیل اهمیت آب و نقش آن در زندگی موجودات زنده، تعیین ارزش واقعی آن حائز اهمیت است. در این تحقیق، به برآورد ارزش آب مازاد کشاورزی شهر اصفهان از نظر مردم اصفهان در سال 1393 پرداخته شد و عوامل مؤثر بر ترجیحات عمومی افراد مورد تحلیل قرار گرفت. با استفاده از روش ارزش‌گذاری مشروط و مدل رگرسیونی لاجیت، تمایل افراد به پرداخت برای استفاده از آب مازاد کشاورزی تعیین و عوامل مؤثر بر آن بررسی شد. نتایج این پژوهش نشان داد که تمایل به پرداخت افراد برای استفاده از هر متر مکعب آب مازاد با متغیرهای سرانه قبض آب و تعداد افراد خانواده و متغیر مبالغ پیشنهادی رابطه منفی و با تحصیلات رابطه مثبت و معنی‌دار دارد. متغیر تعداد افراد خانواده و افراد اخلاق‌گرا بیشترین کشش را به خود اختصاص داده و بیشترین تأثیر را در تمایل به پذیرش افزایش مبلغ قبض آب داشته‌اند. پس از برآورد تابع لاجیت، نتایج نشان داد که متوسط مصرف آب مردم اصفهان برای هر خانواده (با میانگین بعد 4 نفر) برابر با 57/27 متر مکعب در ماه و تمایل به پرداخت هر خانواده اصفهانی برای یک متر مکعب آب مازاد کشاورزی برابر  8/5201 ریال در ماه است.

چکیده [English]

The vital role and significance of water for all lif forms, and for human beings in particular, make it essential to determine its real value. This study was carried out in 2014 with the objective of making an estimation of the value of agricultural surplus water and the parameters determining the general preferences of Isfahani citizens to use this water for drinking purposes. To realize these objectives, the contingent valuation method and the Logit Regression model were used. Results showed that the individuals’ willingness to pay a surcharge for the surplus water had a significantly negative relationship with such variables as per capita water bill, family size, and the proposed price while it had a significantly positive relationship with the individual’s education. Family size and ethical appreciation of environment were found to promote the highest acceptance and the greatest effect on one’s willingness to accept the surcharge on their water bills. Estimation of the Logit function revealed that the average monthly water consumption of each Isfahani family (with an average size of 4) was equal to 27.57 cubic meters and that they would pay a monthly surcharge of 5201.8 Rials for one cubic meter of agriculturtal surplus water.
