This study empirically investigates the impact financial inclusion through digital banking channels has on income inequality in Türkiye using quarterly data for the 2011:Q1-2021:Q4 period. The study uses the Gini index to measure the dependent variable of income inequality and employs two variables as proxies for digital banking. The first variable is the share of the investment volume in the total financial transaction volume made by retail customers through Internet banking. The second variable is a factor constructed based on the transaction volume per unitof main items under financial transactions. The study relies on time series approaches to test whether digital banking-driven financial inclusion has a significant impact on income inequality in Türkiye. As for the empirical evidence, the study employs the dynamic ordinary least squares method to obtain long-run coefficients, a vector autoregressive model to obtain short-run dynamics through impulse response functions with biascorrected bootstrap confidence intervals that account for the bias and skewness of the small sample, and a causality analysis. The findings show that digital financial inclusion has a widening impact on income inequality. Regarding the dynamic interactions, the Gini coefficient has been discovered to increase in response to digital banking innovations. The findings also reveal digital banking to have a forecasting ability on income inequality in Türkiye regarding the sample period.

Bu çalışma Türkiye’de dijital bankacılık kanalıyla yaygınlaşan finansal içerilmenin gelir eşitsizliği üzerine etkisini 2011:Ç1 ve 2021:Ç4 dönemine ait çeyreklik veri seti ile ampirik olarak incelemiştir. Gelir eşitsizliğini ölçmek için kullandığımız Gini katsayısı bağımlı değişken olarak belirlenmiştir. Dijital bankacılığı ölçmek için iki tane vekil değişken kullanılmıştır. Birinci vekil değişken Internet bankacılığı kanalıyla bireysel müşteriler tarafından yapılan yatırım işlemlerine ait işlem hacminin toplam finansal işlemler hacmi içindeki payı olarak belirlenmiştir. İkinci vekil değişken ise yine bireysel yatırımcılar tarafından Internet bankacılığı kanalıyla yapılan ve finansal işlemler altındaki kalemlerin birim başına düşen işlem hacimlerinden elde edilen faktör olarak belirlenmiştir. Türkiye’de dijital bankacılık yoluyla artan finansal içerilmenin gelir eşitsizliği üzerinde anlamlı bir etkisinin olup olmadığını test etmek için zaman serileri yaklaşımları kullanılmıştır. Ampirik bulgular için dinamik olağan en küçük kareler yöntemi, küçük örneklemler için yanlılığı ve çarpıklığı dikkate alan güven aralıklarına sahip etki-tepki fonksiyonlarını ede etmek için vektör otoregresif modeli ve nedensellik testi kullanılmıştır. Analiz sonuçlarına göre dijital finansal içerilme zengin ve yoksul hane halkları arasındaki gelir eşitsizliğini arttırıcı etki göstermiştir. Dinamik etkileşimler dikkate alındığında ise dijital bankacılık kullanımının yaygınlaşmasına tepki olarak Gini katsayısının arttığı ortaya çıkmıştır. Ayrıca, Türkiye için söz konusu analiz döneminde dijital bankacılıktan gelireşitsizliğine doğru tek yönlü bir nedensellik ortaya koyulmuştur.
