The article deals with the development of one of the service sectors, which is considered an element of the economic basis of the post-industrial development stage. The author considers the main indicators of the sector growth in the most competitive OECD countries, as well as compares the main macroeconomic structural and dynamic indicators of business and professional services in the USA and Kazakhstan, which made it possible to identify the main positions of Kazakhstan’s lag. A comprehensive analysis of the dynamics and structure of the development of post-industrial services in Kazakhstan was carried out in all the significant parameters of the development of the types of services of this group that are available in domestic statistics. This made it possible to identify a group of development leaders; activities characterized by stability and a high market share, but weak dynamics; shrinking sectors. The negative trends in the development of the post-industrial services sector, determined as a result of the analysis and assessment, allow us to form a vision for further steps to develop them.
