Small business in structural shifts in Ukrainian economy during 2012-2022 in the context of solving the problems of economic development

The article is devoted to testing the author’s methodology for assessing the contribution of structural changes (distribution of the employees’ total number between large, medium and small enterprises) to the processes of socio-economic development in Ukraine. For this purpose, the general trends in the dynamics of the scale and efficiency of the sector of Ukrainian non-financial enterprises and the specifics of such trends for enterprises with different scales of economic activity are studied for the retrospective period 2012-2022. Due to the fundamental differences in the factors of economic dynamics, the years of relatively stable political and epidemiological situation are studied separately from the years of significant political, military-political and epidemiological disturbances. Using the additive-multiplicative model of the value added, created by Ukrainian enterprises dependence on the number of employees, the proportions of their distribution among large, medium and small enterprises and labor productivity (value added per capita) and the method of sequential substitutions, the author conducts a factor analysis of the dynamics of value added created by Ukrainian enterprises in the retrospective period. Evidence of significant convergence of the economic efficiency level of small and large enterprises during the retrospective period and the leading role of small enterprises in improving the efficiency of economic activity in Ukraine and ensuring the resilience of the economy to negative external and internal disturbances is obtained.
