Model of assessment of financial imbalances in regions of Ukraine

The paper deals with the assessment of the socio-economic development of Ukrainian regions using Data Science methods and multidimensional analysis, including taxonomy, n-dimensional classification, and ensemble decision trees methods. The methodological bases of economic regions devel¬opment by the economic and mathematical modeling methods were investigated. The necessity of improving and further developing estimation models of the regional economic development using business analytics tools and multidimensional scaling methods was investigated.
The ensemble decision trees methods was applied for the classification model of economic development of the Ukrainian regions according to the conceptual base of the research on regional econom¬ic development. It will increase the quality level of administrative decisions making on regional de¬velopment asymmetry equalization. It is determined that in Ukraine, there is a significant imbalance of regions clusters with high and low economic level. Here was investigated the relationship between the two groups of economic development indicators – the indicators of the economic development regional performance and the group of economic potential. The results of the classification model allow identifying the set of indicators that have significant impact on the overall economic development. The developed ensemble model allows carrying out qualitative recognition and prediction of the state probability of economic development. It will improve the quality of decision making pro¬cesses on equalization of regional development asymmetry.
The further research gives the possibility to develop the system of levers directions of regional development imbalance equalization, to determine priority vectors of sustainable development of both the regions and the country.

The influence of information is the main productive force and the subject of production for the economic systems development. Information services contribute to the competitive economy, to the provision of optimal conditions for human development, and the implementation of effective democratic procedures. The results of the socio-economic development of Ukraine testify to the growing lag of the parameters of its competitiveness from many countries of the world and to the strengthening of differentiation in the regional development. Since the regional environment today largely determines the competitiveness of the entire national economy, it becomes important to discuss the appropriate methodological tools for assessing the development level of information and communication infrastructure (ICI) in the regions of Ukraine.
Given the necessity of solving a specific problem, a methodological approach to assessing the development level of ICI is proposed, which is based on the calculations of integral indicators by the entropy method and aimed at the implementation of a group of economic regions in accordance with its defined parameters. The improved methodical toolkit takes into account consistent stages of the system for estimating indicators, which allows to analyze and evaluate the levels of ICI regions development and to obtain the value of specific digital divisions between individual regions.
The implementation of the proposed scientific and methodological approach allowed to obtain the results of the assessment of the ICI development level, to allocate regional clusters depending on the ICI development levels, to identify factors that restrain the ICI development in the regions and to propose recommendations for their elimination.

Nowadays in Ukrainian realities decentralization, as a process of expanding and strengthening the rights and powers of administrative-territorial units, contributes to the development of financial innovations, the accessibility of public goods, and improvements in the quality of life of the population.
The aim of the article goal is developing the recommendations for improving the financial support of the regions by introducing new tools of influence of communities and local self-governments on the economic growth of territories.
Using the methods of factor analysis, regression analysis, and significant components, the article determines the impact of regional economic development on the revenues of local budgets. The empirical findings show the close correlation between budgetary decentralization and industrial capabilities of the regions. A cluster analysis was carried out to identify the asymmetries of regional development in terms of financial capacity. It enabled to distinguish homogeneous groups of areas according to the indicators of their economic development. On this basis the authors substantiated the necessity of entrepreneurial activity stimulating, increasing the number of companies, and promoting a continuous flow of goods (works, services) from the producer to the consumer in different regions of Ukraine.
