As one of the mother industries, the petrochemical industry is one of the essential pillars of development and the driving engine of various sectors of the country’s economy. This industry will achieve several important goals, such as increasing export income, expanding downstream sectors, creating jobs, and increasing GDP. This importance has been emphasized in the country’s upstream documents, such as the general policies of the resistance economy, focusing on developing petroleum refineries to prevent the vulnerability of oil and gas revenues by extending the value chain and increasing the export of these products. The current work aims to investigate the value chain of the petrochemical industry with the new approach of petrochemical refineries, as well as the pathology and evaluation of the current state of the chains mentioned above in the country with the descriptive research method and the library method using policy research. The research results show that the chain of petrochemical products with the approach of creating petrochemical refineries has relatively high advantages compared to focusing on chains with the traditional method.
