بررسي ميزان تاثير مصرف انرژي هاي تجديدپذير و تجديدناپذير بر رشد اقتصادي كشورهاي منتخب در حال توسعه (شامل ايران)، دوره ي زماني 2009-1980

An Investigation of the Contribution of Renewable and Non-Renewable Energies to Economic Growth of Selected Developing Countries (Including Iran) over the Period of 1980-2009

انرژي هاي تجديدپذير، با طبيعت و محيط زيست سازگاريِ بيش‎تري دارند، توليد و تهيه ي آن‎ها آلايندگي زيست محيطي ناچيزي دارد و چون تجديدپذيرند، براي آن‎ها پايانِ نزديكي متصور نيست. از اين رو، انرژي هاي تجديدپذير، روزبه روز سهمِ بيش‎تري در سامانه ي تامينِ انرژي جهان به عهده مي گيرند. دسترسي كشورهاي درحال توسعه به انواع منابع جديد انرژي، براي توسعه ي اقتصادي آن‎ها اهميت دارد. پژوهش هاي جديد حاكي از آن است كه بين سطح رشد و ميزانِ مصرف انرژي يك كشور، رابطه‎ي مستقيمي برقرار است. در اين مطالعه به منظور بررسي رابطه ي بين مصرف انرژي هاي تجديدپذير و تجديدناپذير با رشد اقتصادي در ميان كشورهاي منتخب در حال توسعه، شامل ايران، در دوره ي زماني 2009- 1980، از آزمون هاي ريشه‎ي واحد پانلي، هم انباشتگي پانلي و حداقل مربعات ادغام شده استفاده شده است. نتايج پژوهش نشان مي دهد كه در بين كشورهاي منتخب در حال توسعه، بين متغيرها در بلندمدت، رابطه ي هم انباشتگي وجود دارد. هم‎چنين، طي دوره ي مورد بررسي، ضريبِ ميزان اثرگذاريِ بلندمدتِ مصرفِ انرژيِ تجديدناپذير (مصرف انرژي با منابع متعارف) بيش‎تر از ضريبِ ميزان اثرگذاريِ بلندمدتِ مصرف انرژي تجديدپذير بر رشد اقتصادي در كشورهاي منتخب در حال توسعه مي باشد.

An Investigation of the Contribution of Renewable and Non-Renewable Energies to Economic Growth of Selected Developing Countries (Including Iran) over the Period of 1980-2009 Mohammad Hassan Fotros* Associate Professor, Faculty of Economics and Social Sciences, Bu-Ali Sina University, fotros@basu.ac.ir Akbar Aghazadeh Faculty Member, Islamic Azad University of Mako, ak_aghazadeh2007@yahoo.com Sevda Jabraili MA in Economics, sevdajabraili@yahoo.com Received: 2011/6/13 Accepted: 2011/12/18 Abstract Renewable energies are more compatible with sustainable development as they are renewable and have minimal negative environmental impacts in their production process. As a result renewable energies are increasing their share in the global system of energy provision. Given the observed positive correlation between economic growth and energy consumption, it is clear that the achievement of developmental goals of developing countries is dependent on their access to new sources of energy. This study investigates the relationships between renewable and nonrenewable energy consumptions and economic growth of selected developing countries (including Iran) during the period of 1980-2009. It does so by using panel unit root, panel Cointegration, and pooled least square econometric procedures and tests to analysis the eventual relations between the variables within the selected countries. The study confirms the existence of a Cointegration relationship between energy consumption and economic growth in the selected developing countries. The results further reveal that the impact of consumptiomn of nonrenewable energies on growth has been greater than that of renewable energies in the period of study.
