Factors Affecting the Voluntary Implementation of Internal Audit

Öz

The decision to establish an internal audit function within a business can be prompted either by legal regulators, who are external stakeholders of the company, or by internal needs that arise within the company. This study investigates the factors influencing the decision to voluntarily establish an internal audit function in businesses. Within this scope, hypotheses derived from agency theory and transaction cost theory are analyzed using logistic regression on non-financial firms listed on the BIST (Borsa Istanbul) stock exchange, specifically focusing on a subset of manufacturing companies. According to the results obtained, the size of business assets in the non-financial sector is the only variable that affects the establishment of internal audit. In addition to this, the number of meetings of the audit committee and the fact that the independent auditor is one of the four big variables in manufacturing enterprises were also determined as variables with a significant effect. The effect direction of the variables is positive for the first two and negative for the last. In addition, the results of the study were compared with similar studies in the literature and the similarities and differences between the obtained results were revealed.

İç Denetimin Gönüllü Olarak Uygulanmasına Etki Eden Faktörler

Öz

İşletme bünyesinde bir iç denetim fonksiyonu kurulması kararı işletmenin dış paydaşlarından olan yasal düzenleyicilerin emretmesi sonucu olabileceği gibi işletme içerisinde ortaya çıkan ihtiyaçlarla da oluşabilir. Bu çalışmada işletmelerde gönüllü olarak iç denetim fonksiyonu kurulması kararına etki eden faktörler araştırılmıştır. Bu kapsamda vekalet teorisi ve işlem maliyeti teorisinden yola çıkarak belirlenen hipotezler BIST’te yer alan finans dışı işletmeler ve bunun bir alt grubu olan imalat sektörü işletmeleri üzerinde lojistik regresyon yöntemi ile analiz edilmiştir. Elde edilen sonuçlara göre finans dışı sektörde işletme varlıklarının büyüklüğü iç denetimin kurulmasına etki eden tek değişken olarak karşımıza çıkmaktadır. İmalat işletmelerinde ise buna ilave olarak denetim komitesinin toplantı sayısı ve bağımsız denetçinin dört büyüklerden biri olması da anlamlı etkiye sahip değişkenler olarak belirlenmiştir. Değişkenlerin etki yönü ilk ikisi için pozitif, sonuncusu için negatiftir. Ayrıca, çalışma sonuçları literatürde yapılan benzer çalışmalarla karşılaştırılmış ve ulaşılan sonuçlar arasındaki benzerlik ve farklılıklar ortaya koyulmuştur.
