Econometric analysis of the structure and sustainability of Ukraine socio-economic system in the context of the economic systems theory

Nowadays, studying the categories of “economic sustainability”, “economic sustainability management” and the peculiarities of these concepts is especially relevant. Their use would provide an opportunity to ensure the sustainable and most effective functioning of the subject of economic relations in the current period of time, as well as to create a high potential for its development and ensuring the conditions for investing capital in the Ukrainian economy. All this determined the purpose of this study, which consists in the analysis of the theory and essence of the economic sustainability concept, the interpretation of the concept of “economic sustainability of the system” and the concept of “management of economic sustainability of the system”, distinguishing factors affecting the sustainability of the Ukrainian economic system, determining the relationship of economic sustainability with economic security, investing as well as forecasting the level of the Ukrainian economy sustainability based on the innovative modeling methods. The object of the research is to develop the theory of the “economic sustainability” concept and to determine the level of economic sustainability of the economy aimed at raising the investment climate in Ukraine. To ensure the development, security and investment attractiveness of the Ukrainian economy, an organizational structure of the management model for the sustainability of the Ukrainian economic system was developed using the developed economic and mathematical model.

The firm’s effective alignment of Information Communication Technology (ICT) capabilities with the SME’s business process to achieve agile communication strategies will distinguish profitable and failing firms in this global market milieu. The paper examined SMEs’ communication strategies in South Africa and Nigeria by evaluating their ability to align business and IT to promote innovation and competitive edge in their operations. Quantitative data from 230 SMEs in Nigeria and South Africa were presented. The findings indicated that the business manager’s knowledge of IT understanding is limited (= .29), the effectiveness of IT and business liaison and cooperation (= .30), and the dynamic of IT-based decision-making (= .33), and the SME’s knowledge sharing experiences through organization learning (= –.07). These findings showed a lack of communication effectiveness due to the inability to align ICT capabilities with the SME’s communications strategies. Similarly, an inverse correlation between communication and ICT infrastructure (–.26); between communication and skill (–.32); between communication and business and IT governance (–.71); between communication and ICT value that the SMEs derived from their use of information communication technology (–.78) due to lack of business and IT alignment. The paper recommends that SMEs must not rely on the acquisition of ICT infrastructure but must ensure its integration with their business processes.

Machine-building complex is a system-forming element of Ukrainian economy. Functioning of other industries in many respects depends on the results of its activity. Harsh conditions of globalized economic environment and geopolitical changes taking place in the country have negatively affected the state of machine-building enterprises and determined the need for increasing the level of their economic sustainability. As a result of using the systemic-structural approach, which is being developed in the context of the provisions of systemic economic theory, systemic-structural analysis of economic sustainability of several machine-building enterprises was performed. The study was conducted based on a sample of 16 machine-building enterprises and covered the 2015−2016 period. Economic sustainability was analyzed by way of defining in the structure of enterprises, econometric modeling and assessing the state of four subsystems with different space and time localization and further defining the level of mutual balance. The set of individual parameters for modeling every subsystem was determined mainly by way of regrouping of baseline statistical indicators, as well as expert assessments. Using such an approach enabled to determine structural peculiarities of machine-building enterprises development during the analyzed period and their effect on formation of volatility and stability properties, which ensure their sustainability in space and time. During the analyzed period, the determined disproportions of the subsystems in the structure of enterprises had systemic nature. The identification of economic manifestations of the determined disproportions enabled to formally define non-trivial dependencies between the economic phenomena, which took place in machine building, and to define the nature of their influence on the mechanism of economic sustainability formation. The risks affecting every subsystem under study had volatile nature, that’s why the issue of systemic risk management remains relevant.
