Abstract:

In the literature, there are studies investigating whether the internal control system and corporate governance principles have an effect on financial performance. However, there is no study investigating the moderator effect of the internal control system on the financial success of corporate governance. For this purpose, it was examined in this study whether there was a moderator effect of the internal control system on the financial success of corporate governance. The study was conducted on companies in the Borsa Istanbul (BIST) corporate governance index (XKURY). The effectiveness of the internal control system was determined by the survey method, and then corporate governance effectiveness ranking was obtained with corporate governance rating scores. The moderator effect was investigated by regression analysis using the data obtained. As a result of the analysis, it has been determined that the internal control system has a moderator effect on the financial success of corporate governance. On the other hand, it is concluded that although corporate governance is thought to have a moderator effect on the financial performance of the internal control system, it does not. This result indicates that the efficiency of the internal control system should be increased for the financial success of corporate governance in enterprises. The reasons for this theoretically unexpected result were investigated in the study.
