چکیده

این پژوهش اثر فناوری اطلاعات و ارتباطات بر انتشار دی‌اکسیدکربن را در کشورهای با درآمد بالاتر از متوسط طی دوره ۱۹۹۵ تا ۲۰۲۲ بررسی می‌کند. به‌منظور سنجش فاوا، شاخص ترکیبی با استفاده از روش تحلیل مؤلفه‌های اصلی تدوین شد تا هم‌خطی میان متغیرهای فناورانه کاهش‌یافته و برآوردهایی پایدارتر و دقیق‌تر حاصل شود. برآورد مدل با روش گشتاورهای تعمیم‌یافته انجام گرفت، نتایج نشان می‌دهد فاوا و مصرف انرژی‌های تجدیدپذیر اثر منفی و معناداری بر انتشار کربن دارند، درحالی‌که رشد درآمد و توسعه صنعتی به طور معناداری موجب افزایش آن می‌شوند. همچنین، صادرات کالاهای با فناوری بالا اثری کاهنده اما از نظر آماری غیرمعنادار بر انتشار کربن دارد. اعتبار ابزارهای مدل نیز با استفاده از آزمون سارگان تأیید شد. انتخاب کشورهای با درآمد بالاتر از متوسط به دلیل شرایط گذار توسعه‌ای آن‌ها صورت گرفت؛ کشورهایی که هم‌زمان از زیرساخت‌های فناورانه نسبتاً پیشرفته و رشد سریع صنعتی برخوردارند. یافته‌های پژوهش نشان می‌دهد توسعه فاوا و گسترش انرژی‌های پاک می‌تواند به‌عنوان راهبردی مؤثر در کاهش آلودگی زیست‌محیطی و پشتیبانی از مسیر توسعه پایدار در این کشورها عمل کند.
