The main purpose of this research is the non-linear effect of the stock index on the development of the industrial sector in Islamic countries. This study is of a causal nature in terms of practical purpose and in terms of data collection and descriptive information. The methodology is post-event. In this research, an attempt was made; By explaining the theory and designing a model to investigate the non-linear effect of the stock index on the development of the industrial sector in Islamic countries, with an emphasis on various indicators of financial development: the soft panel transfer regression (PSTR) approach was investigated. The geographical area of ​​research of Islamic Conference member countries (Albania, Algeria, Azerbaijan, Afghanistan, Iran, Indonesia, Bangladesh, Pakistan, Tajikistan, Turkey, Tunisia, Chad, Senegal, Sierra Leone, Sudan, South African Sahara, Iraq, Oman, Gambia, Qatar, Malaysia) , Mali, Morocco, Egypt and Nigeria) and the time domain of the research is between 2005 and 2019. Using MATLAB software, the data was analyzed through the soft panel transition regression (PSTR) approach, and the results of the analyzes show that There is a non-linear relationship between the stock index and the development of the industrial sector in Islamic countries.
