The modern economy is undergoing processes of structural transformation. The economies of developed countries go through these transformations somewhat earlier, and the economies of developing countries - with a time shift. At the same time, one of the general fundamental trends is a decrease in the share of traditional sectors, in particular industry, in the output structure. As a result, there is a transition to a post-industrial economy. The transformation processes do not end there. The quantitatively developing tertiary (service) sector of the economy is also changing its structure. It highlights the creative economy sector, which is based on creative industries. This is a specific sector of the modern service industry. The article analyzes the role of creative industries as a specific sector of the service sector in the context of the transition from an industrial type of production to a post-industrial one. The author emphasizes the influence of creative industries on economic development and innovation, based on an analysis of changes in the structure of employment and the specifics of consumption in developed countries. Particular attention is paid to how the expansion and deepening of creative industries contributes to economic progress, greater innovation and changes in the nature and structure of employment, transforming society as a whole. The article also examines trends in the development of creative industries and their ability to adapt to the rapidly changing conditions of the global market, emphasizing their role in the formation of a model of sustainable economic and social development. The need to strengthen government support for creative industries is pointed out, because they can become one of the key factors in ensuring Russia's competitiveness in a post-normal world.
