چکیده

هدف اصلی این مقاله بررسی تأثیر فناوری اطلاعات و ارتباطات (ICT) بر مصرف انرژی در کشورهای منتخب منطقه منا طی دوره‌ی زمانی 2011-1995 است. به این منظور از مدل ارائه‌شده توسط سادرسکی (2012) و سه شاخص: تعداد کاربران اینترنت، تعداد خطوط تلفن همراه و تعداد خطوط تلفن ثابت به‌عنوان متغیرهای اندازه‌گیری ICT استفاده شده است. هم‌چنین، با استفاده از روش گشتاورهای تعمیم‌یافته سیستمی (GMM-SYS) کشش‌های کوتاه‌مدت و بلندمدت بین متغیرهای مدل برآورد شده و مورد تجزیه‌و‌تحلیل قرار گرفته است. نتایج نشان می‌دهد که گسترش ICT با هر سه شاخص انداز‌ه‌گیری‌شده، مصرف انرژی سرانه را در کشورهای منتخب منطقه منا در کوتاه‌مدت و بلندمدت افزایش می‌دهد. به‌گونه‌ای که با افزایش یک‌درصدی در این شاخص‌ها، به‌طور متوسط مصرف انرژی سرانه در کوتاه‌مدت و بلندمدت به‌ترتیب 007/0 و 089/0 درصد افزایش می‌یابد.

چکیده [English]

The main objective of this paper is to analysis the impact of information and communication technology (ICT) on energy consumption in the MENA region selected countries during the period 1995-2011. For this purpose, used the model presented by Sadorsky (2012) and three indicators that measured ICT: the number of Internet users, the number of mobile lines and the number of telephone lines. Also, estimated and analyzed the short run and long run elasticities between the variables of the model using a system generalized method of moments (GMM-SYS). The results show that the development of ICT with each three measured indices, increased energy consumption per capita in MENA region selected countries in the short run and long run. So that a one percent increases in this indicator, average of energy consumption increases in the short run and long run respectively 0.007 and 0.089 percent.
