The purpose of this research is to investigate relationship between corporate diversity and bankruptcy risk, with emphasis on differentiation strategies and cost leadership. related data with 97 companies were investigated from 5 industries during the years 1385 to 1396. To measure corporate variation of entropy criteria was used and bankruptcy risk was calculated according to data envelopment analysis technique and Bcc model with the VRS approach. Analytic hierarchy process and expert opinion were used to determine the importance coefficients of the ratios in differentiation strategies and Porter's leadership. To test the research hypotheses were used the logit regression models and resistant panel method. the results show that unlike theoretical issues, corporate diversity does not have a significant effect on corporate bankruptcy risk. Also, there was no significant difference in the cost differentiation strategy and the relationship between corporate diversity and bankruptcy risk. Accordingly, it can be argued that moving toward diversification in the long run does not affect the risk of corporate bankruptcy and the use of Porter's competitive strategies will not be effective.
