The activity of these activists can be effective in the quality of governance and its effectiveness. Therefore, in this study, the relationship between corruption control and the shadow economy of Iran during the years 1374 to 1398 has been examined by using one of the governance indicators, which is corruption control, and using the NARDL method.
