Environmental problems are one of the most challenging issues for the entire world and each country. In economic studies, environmental issues are analyzed as negative externalities. In this article, the negative externalities of electricity production on the output growth of different sectors and household’s welfare in Iran’s economy have been studied through price system using Computable General Equilibrium (CGE) model empirically. In this regard, Iran’s Social Accounting Matrix of 2011 and GAMS software by introducing five scenarios related to environmental effects of electricity production have been used. The results show that firstly, the internalization of electricity production externalities reduces the output of agriculture and industry sectors in all scenarios, while the output of services will increase. Secondly, internalization of electricity production externalities increases total economy’s output and declines the household’s welfare.

Abstract [Persian]

یکی از مهمترین مشکلات در دنیای امروز، مشکلات زیست محیطی است. در مطالعات اقتصادی، مسائل زیست محیطی غالباً تحت عنوان اثرات خارجی منفی مورد بررسی قرار می گیرند. در این پژوهش، اثرات زیست محیطی تولید برق بر رشد ستانده در بخش های مختلف اقتصاد ایران و رفاه خانوار با استفاده از مدل تعادل عمومی قابل محاسبه،در قالب مکانیزم قیمت ها، مورد بررسی و تحلیل قرار گرفته است. به این منظور، با استفاده از ماتریس حسابداری اجتماعی سال 1390، تهیه شده توسط مرکز پژوهش های مجلس شورای اسلامی، و نرم افزار GAMS، بر پایه پنج سناریو تعریف شده این مطالعه صورت گرفته است. نتایج حاصل از مدل نشان می دهد که اولاً درونی سازی اثرات خارجی تولید برق، ستانده بخش های کشاورزی و صنعت را کاهش داده در حالی که ستانده بخش خدمات را افزایش داده است. ثانیاً درونی سازی اثرات خارجی تولید برق ستانده کل و رفاه خانواررا در اقتصاد ایران افزایش می دهد.
