Yeşil finansman, yeşil getiri olmadan mı? Karbon uyumu, üretim ölçeği ve Avrupa çelik sektörünün ihracat rekabet gücü

Öz

Amaç – Bu çalışma, yeşil tahvil ihraçlarıyla ölçülen ülke düzeyindeki yeşil finansmanın, AB'nin gelişen iklim düzenleyici mimarisi kapsamında en karbon yoğun ve ticarete açık sektörlerden biri olan Avrupa çelik sektörünün ihracat performansında ölçülebilir iyileşmelere dönüşüp dönüşmediğini incelemektedir. Tasarım/Veri/Yöntem – Analiz, 2015–2024 döneminde 17 Avrupa ekonomisini kapsamaktadır (N = 170, dengeli panel). Panel Kantil Regresyonu (PQR), en zayıf ihracatçılardan en rekabetçi olanlara kadar ihracat performansının tüm dağılımındaki heterojenliği yakalamak amacıyla kullanılmaktadır. Bulgular – Yeşil tahvil ihraçlarının hiçbir kantil düzeyinde çelik ihracatı üzerinde istatistiksel olarak anlamlı bir etkisi bulunmamakta olup bu sonuç yapısal bir zamansal uyumsuzluk hipotezi çerçevesinde yorumlanmaktadır. Üretim kapasitesi, Q10'da 2,33'ten Q90'da 0,75'e monoton biçimde azalan bir esneklikle baskın ihracat belirleyicisi olarak öne çıkmaktadır. Karbon yoğunluğu ihracatı sürekli olarak baskılamakta olup Q90'da keskin biçimde güçlenen bir etki gözlemlenmektedir. Ortalamaya dayalı EKK tahmin edicileri üretim-ihracat ilişkisinin işaretini tersine çevirmekte ve kantil regresyonunun yapısal olarak heterojen panellerde metodolojik bir zorunluluk olduğunu doğrulamaktadır. Özgünlük/Değer – Bu çalışma, sürdürülebilir finans, ticaret ekonomisi ve sanayi politikasının kesişimindeki bir boşluğu ele alarak büyük bir enerji yoğun sektörde yeşil finansman ile ihracat rekabet gücü arasındaki ilişkiye yönelik özgün kantil panel kanıtları sunmaktadır. Zamansal uyumsuzluk mekanizmasının teorileştirilmesi, belgelenen EKK işaret terselmesi ve farklılaştırılmış kantile dayalı politika önerileri, hem yeşil finansman literatürüne hem de AB karbon piyasası mimarisinin ekonomisine katkı sağlamaktadır.

Green finance without green returns? Carbon compliance, production scale and European steel export competitiveness

Öz

Purpose – This study examines whether country-level green finance, measured by green bond issuances, translates into measurable improvements in the export performance of the European steel sector, one of the most carbon-intensive and trade-exposed industries under the EU's evolving climate regulatory architecture. Design/data/methodology – The analysis covers 17 European economies over 2015–2024 (N = 170, balanced panel). Panel Quantile Regression (PQR) is employed to capture distributional heterogeneity across the full range of export performance, from the weakest to the most competitive exporters. Findings – Green bond issuances exert no statistically significant effect on steel exports at any quantile, interpreted through a structural temporal mismatch hypothesis. Production capacity is the dominant export driver, with a monotonically declining elasticity from 2.33 at Q10 to 0.75 at Q90. Carbon intensity consistently depresses exports, with a sharply amplified effect at Q90. Mean-based OLS estimators reverse the sign of the production-export relationship, confirming that quantile regression is a methodological necessity in structurally heterogeneous panels. Originality/value – This study provides original quantile panel evidence on the green finance, export competitiveness nexus for a major energy intensive sector, addressing a gap at the intersection of sustainable finance, trade economics, and industrial policy. The theorization of the temporal mismatch mechanism, the documented OLS sign reversal, and the differentiated quantile-based policy recommendations constitute contributions to both the green finance literature and the economics of EU carbon market architecture
