As one of the mother industries, the petrochemical industry is one of the most important 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 industries, 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 the development of petroleum refineries, to prevent the vulnerability of oil and gas revenues by developing the value chain and increasing the export of these products. The current thesis 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 aforementioned chains in the country with the descriptive research method and the library method using policy research. The results of the research 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 approach.
