In this study, the relationships between the Consumer Confidence Index, which is one of the subcomponents of the Economic Confidence Index, and the confidence indices of the real sector (manufacturing industry), construction, trade, and services sectors were examined. Monthly data covering the period from January 2011 to January 2024 were used. The stationarity of the series was analyzed using the Augmented Dickey-Fuller (ADF) and Phillips-Perron (PP) unit root tests, while structural breaks were identified through the Bai-Perron multiple structural break test. To determine the relationships, the Autoregressive Distributed Lag (ARDL) model was applied for symmetric effects, and the Nonlinear ARDL (NARDL) model was used for asymmetric effects. According to the results, a long-run relationship was found between the Consumer Confidence Index and the sectoral confidence indices. The manufacturing and services sectors exhibited symmetric effects in the short run and asymmetric effects in the long run, whereas the trade sector displayed asymmetric effects in both the short and long run. The construction sector showed symmetric effects in the short run and statistically significant asymmetric effects in the long run. Based on the findings, sectoral changes were observed to have different impacts on consumer confidence.
Tüketici Güven Endeksi Sektör Güven Endeksleri NARDL Asimetrik Etki
Bu çalışmada, Ekonomik Güven Endeksi'nin alt bileşenlerinden tüketici güven endeksi ile reel kesim (imalat sanayi), inşaat, ticaret ve hizmet sektörü güven endeksleri arasındaki ilişkiler incelenmiştir. 2011:01–2024:01 dönemine ait aylık veriler kullanılmıştır. Serilerin durağanlık düzeyleri Genişletilmiş Dickey-Fuller (ADF) ve Phillips-Perron (PP) birim kök testleriyle analiz edilmiş, yapısal kırılmalar Bai-Perron çoklu yapısal kırılma testi ile belirlenmiştir. İlişkilerin belirlenmesinde, simetrik etkiler için Doğrusal gecikmesi dağıtılmış otoregresif (ARDL) modeli, asimetrik etkiler için doğrusal olmayan ARDL (NARDL) modeli uygulanmıştır. Sonuçlara göre, tüketici güven endeksi ile sektörel güven endeksleri arasında uzun dönemli ilişki tespit edilmiştir. İmalat ve hizmet sektörleri kısa vadede simetrik, uzun vadede asimetrik etkiler gösterirken; ticaret sektörü hem kısa hem uzun vadede asimetrik etkilidir. İnşaat sektörü kısa vadede simetrik, uzun vadede ise anlamlı asimetrik etki yaratmaktadır. Bulgulara göre, sektörel değişimlerin tüketici güveni üzerinde farklı etkiler yarattığı görülmektedir.
