Abstract
The aim of the article is to determine the scientific and theoretical foundations and quantitatively assess the impact of creative industries on economic growth in post-industrial countries. The research used an interdisciplinary approach that combines the methods of structural-analytical, comparative and correlation analysis, systemic generalization and elements of economic and mathematical modeling. The information base was provided by statistical data from UNCTAD, UNESCO, World Bank, DCMS and national statistical offices for the period 2015–2023. Based on the results of an analytical study It is proven that the creative economy is a system-forming component of the post-industrial development model, in which creativity, digitalization and intellectual resources are the main factors of production. The Creative Contribution Index (CCI) was proposed and tested, which allows quantitatively measuring the share of creative industries in GDP creation. Using the example of Great Britain, a high level of correlation was found between indicators of the development of the cultural sector, digitalization and growth of national income. Analysis of global trends showed a stable increase in the export of creative services and the strengthening of the role of Europe and North America as global leaders in the field of creative production. The results of the study confirm that the creative economy is becoming not only an economic phenomenon, but also a socio-cultural mechanism for innovative development and increasing the competitiveness of post-industrial countries.
