چکیده

تغییرات آب و هوایی در حال تبدیل شدن به یک بحران جهانی است. بحرانی که تمام جنبه‌های زندگی انسان روی زمین، از جمله اقتصاد را تحت تاثیر قرار می‌دهد. به همین دلیل، حفظ محیط زیست و دستیابی به اهداف توسعه پایدار اکنون در دستور کار بسیاری از دولت‌ها قرار دارد.
این مقاله از مدل رگرسیون انتقال ملایم تابلویی برای آزمون نقش فناوری اطلاعات و ارتباطات به عنوان متغیر انتقال استفاده می‌کند. به‌طور خاص در این پژوهش بررسی می‌شود که آیا ICT می‌تواند با تغییر اثر بهره‌وری بر انتشارآلاینده‌ها موجب جداسازی رشد اقتصادی از افزایش آلودگی شود. هدف این است که نشان دهیم آیا سیاست‌گذاران می‌توانند از توسعه اقتصاد دیجیتال در سراسر جهان برای دستیابی به نتایج زیست‌محیطی و اقتصادی بهتر استفاده کنند یا خیر؟ این مطالعه در مقیاس جهانی انجام شده و از داده‌های 108 کشور جهان در دوره زمانی 2019-2003 استفاده شده است. نتایج نشان می‌دهد الگوی انتشار CO2 از یک مدل غیرخطی با ICT به عنوان یک متغیر انتقالی پیروی می‌کند که اثر بهره‌وری کل عوامل بر انتشار CO2 را تحت تأثیر قرار می‌دهد. استفاده بیشتر از ICT کارایی کربن را بهبود می‌بخشد و تغییرات آب و هوایی را کاهش دهد.

چکیده [English]

Climate change is becoming a global crisis that can affect all aspects of human life on Earth, including the economy. So, protecting the environment and achieving sustainable development goals are now on the agenda of many governments.
This article uses the Panel Smooth Transition Regression Model to test the role of information communication technology as a transition variable. In this research, it is investigated whether ICT can decouple the economic growth from the increase in pollution by changing the effect of productivity on CO2 emission. The goal is to show whether policymakers can use the development of the digital economy around the world to achieve better environmental and economic outcomes. This study was conducted on a global scale and data from 108 countries was used from 2003 to 2019. The results show that the co2 emission follows a PSTR model with ICT as a transition variable that changes the effect of total factor productivity on co2 emission in favor of the environment. ICT development will improve carbon efficiency and reduce climate change.
