چکیده

فناوری اطلاعات و ارتباطات(ICT)  می‌تواند تاثیری شایان بر مصرف انرژی داشته باشد. بنابراین، شناخت مقدار این تاثیر برای برنامه‌ریزی در حوزه ICT و انرژی ضرورت دارد. بنابراین، هدف این مطالعه بررسی تاثیر گسترش فناوری اطلاعات و ارتباطات (ICT) بر مصرف انرژی‌های تجدیدپذیر در بخش‌های اقتصادی ایران است. بدین منظور از داده‌های تابلویی شامل داده‌های سه بخش کشاورزی، صنعت و خدمات در طول سالهای 1395-1379 استفاده شده است و با استفاده از آزمون ریشه واحد مشخص شد که متغیرها هم مانا و هم نامانا هستند بنابراین، از روش میانگین گروهی (MG) برای تخمین رابطه بلندمدت استفاده شد. نتایج نشان دادند که در بلند مدت افزایش تعداد کاربران اینترنت و مشترکین تلفن همراه موجب کاهش مصرف انرژی تجدیدپذیر می‌شود. به این علت که گسترش زیرساخت های فناوری اطلاعات و ارتباطات موجب توسعه دولت الکترونیک، افزایش دور کاری،کاهش ترافیک و در نتیجه صرفه جویی در مصرف انرژی می‌شود، ولی در کوتاه مدت با افزایش مشترکین تلفن همراه و مشترکین تلفن ثابت مصرف انرژی افزایش می‌یابد. هم‌چنین، افزایش GDP در کوتاه مدت نیز باعث افزایش مصرف انرژی می‌شود. در نتیجه در بلندمدت گسترش ICT می‌تواند موجب صرفه‌جویی در مصرف انرژی شود و بنابراین، دولت‌ها برای مدیریت بهتر مصرف انرژی باید از ظرفیت‌های ICT استفاده بهینه نمایند.

چکیده [English]

This paper aimed to examine the effects of ICT developments on the renewable energy consumption in the economic sectors of Iran. The panel data for study were obtained from three sectors of agriculture, industry, and services within the 2000-2016 timeframe; the unit-root test showed that the variables were both stationary and nonstationary. As a result, the mean group was used to estimate the long-run effects, and it revealed that, in the long run, the increase in the number of the Internet and cellphone users decreases the renewable energy consumption. In addition, the GDP and investment growth increases the energy consumption, because the growth of information and communication technology infrastructures develops the e-government and teleworking and reduces the traffic, and, in turn, conserves the energy. However, the increase in the number of landline and cellphone users in the short run increases the energy consumption. The GDP increase will also raise the energy consumption in the short run.
