Abstract
The issues of the petrochemical industry development of the Republic of Kazakhstan by creating a petrochemical cluster in the western oil and gas region of the country are studied. The issues of creating a petrochemical cluster in Kazakhstan and creating an integrated petrochemical complex in the Atyrau region are considered. The essence of the cluster approach as the main factor in increasing the regional competitiveness of the Atyrau region is revealed, and the expediency and efficiency of creating a petrochemical cluster and an integrated petrochemical complex are substantiated. The stages of construction of an integrated petrochemical complex are described depending on the sources of supply of raw materials used. A schematic diagram of the formation of a petrochemical cluster in Kazakhstan is created. The main groups of factors substantiating the possibilities and economic expediency of creating a petrochemical cluster, which ensures the high profitability of this industry, are determined. It is shown that the innovative petrochemical cluster makes it possible to accelerate the diversification of the economy and the activation of non-primary, high-tech industries.
