For this purpose, fsQCA software was used for qualitative comparative analysis and smartPLS3 was used for Reliability, Validity, and also to examine the models. The results led to the identification of three models, which were tested through structural equation modeling. Finally, the results showed that in the first path, entrepreneurial intention with the absence of political stability, the absence of supervisory quality, and the absence of the rule of law; In the second causal configuration, the presence of political stability, the absence of government efficiency, the presence of supervisory quality, and the presence of the rule of law, and in the third causal path in the direction of entrepreneurial intention, with the four conditions of the absence of political stability, the presence of government efficiency, the presence of supervisory quality, and the presence of the rule of law.
