چکیده

تجارت بین کشورها و تغییرات اقلیمی از عوامل اثرگذار بر نابرابری درآمدی است؛ به طوری‌که پدیده جهانی شدن و ارتباط متقابل تجاری بین کشورها، نابرابری درآمدی در کشورهای طرف تجارت را کاهش داده است. از طرفی تغییرات اقلیمی به عنوان مسأله مهم و حال حاضر جهان، اثراتی را بر رشد اقتصادی و نابرابری درآمدی کشورها داشته که بررسی و تحلیل ارتباط بین تجارت و تغییرات اقلیمی با نابرابری درآمدی، هدف اصلی این پژوهش است. در این پژوهش، از الگوی رگرسیون کوانتایل داده‌های تابلویی برای بررسی اثرات نامتقارن تجارت و تغییرات اقلیمی بر نابرابری درآمدی در 60 کشور عضو شاخص عملکرد تغییرات اقلیمی برای دوره 2020-2010 استفاده شده است. به‌علاوه برای تغییرات اقلیمی از شاخص عملکرد تغییرات اقلیمی و برای تجارت از شاخص درجه باز بودن تجاری استفاده شده است. نتایج نشان می‌دهد تغییرات اقلیمی در طول این سال‌ها، نابرابری درآمدی را در کشورهای منتخب افزایش داده است. همچنین دهک سوم تا دهک هفتم درآمدی بیشترین اثرپذیری را از تغییرات اقلیمی در طول سال‌های مورد بررسی داشته است. از طرفی تجارت بین کشورها نابرابری درآمدی کشورهای منتخب را در دهک‌های مختلف درآمدی کاهش داده است.

چکیده [English]

Trade and climate change are some of the important factors affecting income inequality. With the globalization and trade interrelationships between countries, income inequality has been reduced to some extent. On the other hand, climate change as an important and current issue in the world has had great effects on economic growth and income inequality of countries. The purpose of this study is to analyze the relationship between trade and climate change and income inequality. To examine the asymmetric effects of trade and climate change on income inequality in 60 countries, the quantile panel regression model is used by 2010 to 2020 data. In addition, the Climate Change Performance Index for climate change and the Trade Openness Index for trade has been used. The results show that climate change over the years has increased income inequality in selected countries. Also, the results show that the third to seventh quantiles of income have been most affected by climate change. On the other hand, trade between countries has reduced the inequality of selected countries in different income quantiles.
