The main purpose of this study is to investigate the relationship between some firm attributes and earnings persistence as one of the criteria of earnings quality, in order to identify which firm attributes have a significant relationship with earnings quality. For this purpose, data from 125 firms listed in Tehran Stock Exchange during 2010 to 2014 and linear regression are used. The results of the study show that there is not a relationship between firm's differentiation strategy and its earnings persistence; there is a direct relationship between firm's audit quality; and a direct relationship between firm's ownership structure (ownership concentration) and earnings persistence.
