The existence of diverse ethnic (Sistani and Baluch) and religious (Shiite and Sunni) compositions in the villages of Sistan and the transfer of village management to councils and village heads in the country's new management system has revealed the impact of clan tendencies in the selection of local managers and ultimately its impact on the quality of rural management. Accordingly, the present study has been done with the aim of investigating the effects of tribalism on the quality of management in Sistan villages and provide appropriate strategies. This research is based on a combination of descriptive-analytical methods and based on library studies, documentary and field studies in which statistical population of the study consisted of 9356 people of voting age in households living in 40 sample villages with councils and villages in the Sistan region, of which 369 people were randomly selected as the sample size based on the Cochran formula. The data collection tool was a questionnaire, the validity of which was confirmed based on the opinions of experts. In order to examine its reliability level, Cronbach's alpha coefficient was also calculated. Data analysis was performed with the help of SPSS, ArcGIS, and Expert Choice software, using the ARAS model and stepwise linear and multivariate regression tests. The results show that the Sistan villages have a significant difference in terms of quality of rural management and tribalism intensity. Also, the study of severity of impacts of tribalism on the quality of management of the studied villages based on the results of regression test at 99% confidence level confirms that 13.5% of the fluctuations in the quality of rural management can be predicted through the severity of tribalism. According to the research results, it is essential to adopt measures to guide rural communities in the right and far-sighted directions for selecting local managers based on meritocracy, knowledge, and experience. In this regard, the interaction between formal management structures and informal social networks should be organized in a synergistic manner.
