Assessment of the structural complexity of regional economies and its impact on GRP

The purpose of this work is to build an integral index of structural complexity based on four basic indices of complexity of regional economies: the index of complexity of GRP structures according to data on production volumes by type of economic activity (TEA); the index of complexity of employment structures of regions by professional groups; the index of complexity of employment structures of regions according to TEA; the index of complexity of structures of distribution of enterprises in regions. Four integral indices of the structural complexity of regional economies have been constructed. It is shown that the structural complexity of the regional economy has an impact on GRP. Estimates of the elasticity of GRP according to the integral index of structural complexity are obtained. The integral index of the structural complexity of regional economies makes it possible to comprehensively assess the economic potential of territories, identify the most promising industries and industries, as well as identify areas of diversification that contribute to strengthening the economic security of regions under sanctions pressure. This creates the basis for the formation of sound spatial development strategies aimed at increasing the economic complexity and sustainability of regional economies.
