Abstract:
This study investigates the impact of bank system size, capital adequacy, and credit on CO2 emissions in 66 selected countries. To this end, a novel method of Quantile Regression by Powell (2020) is applied to panel data from 2000 to 2017. Our findings reveal that Banking system size has a positive impact, while renewable energy consumption and population show a negative and significant impact on CO2 emissions in all quantiles. Credit and economic growth have a positive and significant impact on lower-emissions countries, and vice versa for high-emissions countries. In contrast, Capital adequacy significantly reduces CO2 emissions in the lower CO2 emissions countries (25th to 75th quantiles) and vice versa for the high emissions countries. Furthermore, renewable energy consumption and population exhibit a negative and significant impact across all quantities (25th to 95th percentile). Policymakers can use insights into how banking system-specific characteristics impact CO2 emissions to see their capacity to reduce such emissions.
المستخلص:
تدرس هذه الدراسة تأثير حجم النظام المصرفي، وكفاية رأس المال، والائتمان على انبعاثات ثاني أكسيد الكربون في 66 دولة مختارة. ولتحقيق هذه الغاية، طُبقت طريقة جديدة للانحدار الكمي (Quantile Regression) من قِبل Powell (2020) على بيانات السلاسل الزمنية المقطعية للفترة من 2000 إلى2017. تكشف نتائجنا أن لحجم النظام المصرفي تأثيرًا إيجابيًا، بينما يُظهر استهلاك الطاقة المتجددة والنمو السكاني تأثيرًا سلبيًا وهامًا على انبعاثات ثاني أكسيد الكربون في جميع الأرباع. كما يُظهر الائتمان والنمو الاقتصادي تأثيرًا إيجابيًا وهامًا على الدول ذات الانبعاثات المنخفضة، والعكس صحيح بالنسبة للدول ذات الانبعاثات المرتفعة. في المقابل، تُقلل كفاية رأس المال بشكل ملحوظ من انبعاثات ثاني أكسيد الكربون في الدول ذات الانبعاثات المنخفضة (من الربع الأول " 25" إلى الربع الثالث "75")، والعكس صحيح بالنسبة للدول ذات الانبعاثات المرتفعة. علاوة على ذلك، يُظهر استهلاك الطاقة المتجددة والنمو السكاني تأثيرًا سلبيًا وهامًا على جميع الارباع (من الربع الأول "25" إلى الرابع "95"). يمكن لواضعي السياسات الاستفادة من هذه المعلومات حول كيفية تأثير خصائص النظام المصرفي على انبعاثات ثاني أكسيد الكربون لتقييم قدرتهم على خفض هذه الانبعاثات.
