| چکیده | ||
| در این پژوهش با استفاده از تکنیکهای ورودی تحلیل پوششی دادهها، شاخصهای کارایی و بهرهوری مصرف آب تهران برای دورۀ زمانی 1384ـ 1392 ارزیابی شد. همچنین همبستگی بین مصرف آب و فعالیتهای اقتصادی منطقه با استفاده از شاخص تولید ناخالص داخلی منطقهای بررسی شد. نتایج نشان میدهد که بهرهوری کل از نظر تغییر کارایی فنی و تغییر کارایی مقیاس، به‌ترتیب 80/1 و 68/1 درصد بهبود یافته است. علاوه بر آن، به‌علت اجرای طرحهای کلان، جمع‌آوری و تصفیۀ فاضلاب و همچنین به‌کار بردن راهکارهای مدیریت مصرف آب برای افزایش ذخیرۀ سالانۀ آب به‌ویژه از سال 1390 به بعد، بهرهوری کل از نظر تغییر فناوری، 32/12 درصد بهبود یافته است. این شاخصها تأیید میکند که بدون کاهش در میزان تولیدات و خدمات عمدۀ مربوط به تهران، امکان کاهش مصرف آب تا 22 میلیون متر مکعب در این شهر میسر است. | ||

| چکیده [English] | ||
| The input-oriented Data Envelopment Analysis was used to measure the water use efficiency and productivity indices of Tehran over the period 2005-13. Meanwhile, the correlation between water uses and regional economic activities was examined using the gross regional domestic product index. The results indicated that the total productivity was improved 1.8% and 1.68% aspect of technical efficiency change and scale efficiency change respectively. Furthermore, it was improved 12.32% aspect of technology change due to accumulation and treatment of waste water and applying water use management to increase annual water storage since 2011. The mentioned indices confirmed that a 22 million cubic meters decrease is possible in water uses without decreasing in the level of gross products related to Tehran. | ||
