The present study designs an earnings management improvement model appropriate for Iranian knowledge-based firms (KBFs). This study is interpretive in the model exploration phase and positivist in the model testing phase, and in general, this is applied research. The research sample in the qualitative phase comprises the experts in the field of earnings management, including accounting faculty members (۸), senior managers of KBFs (۷), and members of the Iranian National Tax Administration (INTA) (۵); thus, a total number of ۲۰ experts were interviewed to collect the qualitative data. The research questionnaire for collecting the quantitative data was designed according to the exploratory factor analysis (EFA). In the quantitative phase, using the sample size calculator (the G*Power software) at the alpha level of ۰.۱ and test power of ۰.۸۵, the final research sample comprises ۱۵۳ participants. The research approach uses mixed methods, and the employed strategy is grounded theory. The constant comparative method in the three stages of open, axial, and selective coding based on the Strauss et al. (۱۹۹۶) method and the MAXQDA software was employed to analyse the data. The path analysis of the explored model was carried out based on the variance-based structural equation modeling (SEM) using SPSS version ۲۴ and Smart PLS ۳.۰. The study results indicate ۵۳ indicators, including more than ۱۸ components and ۷ latent variables.
