The purpose of this research is to investigate the effects of internal and external rewards on employee performance with the mediation of employee motivation variable of Mapna Group, Development Company One. The hypotheses of this research examine the indirect effect of internal and external rewards on motivation through internal and external attribution. In addition, it also examines the effect of internal and external attribution on motivation and motivation on performance. The current research is based on a comparative approach. In order to check the hypotheses, a quantitative approach has been used. In order to collect data, a standard online questionnaire based on a 5-point Likert scale was used. Considering that the statistical population of the research consisted of 570 employees of the Development Company, 230 people were considered as the sample size. SPSS 27 and Smart PLS 3 software were also used to analyze the data. The results show that among the indirect effects, only internal rewards through external attribution have an effect on employee motivation. Also, among the direct effects, the effect of external attribution on motivation, and the effect of motivation on performance were confirmed. Due to the dispersion of the statistical population in different cities, the questionnaire was distributed online. Also, the current research was conducted cross-sectionally. In addition to this, the examination of other samples and the comparison of the results and the qualitative examination of the reasons for the rejection of some hypotheses are not included in the framework of this research. The managers of Mapna Development Group can use the results of this study to improve the motivation of employees. Considering that motivation has a direct effect on employee performance, the results of this research can be used to improve employee performance. This research is one of the few studies that have investigated the human resources situation in Mapna Development Group. Also, the current research is looking for a way to improve the motivation and consequently the performance of the organization's employees by examining the variables of internal and external rewards, taking into account internal and external attribution. Considering that the previous studies did not examine all the variables used in the present study at once, this issue can be considered as an innovation of the present study.
