The article's purpose was to econometric substantiate the peculiarities of achieving a synergistic effect and sources of economies of scale for participants in entrepreneurial networks, for example, industrial enterprises in Ukraine. The regression analysis method has been used to identify sources of economies of scale of production, which change affects the efficiency of enterprises. With the elasticity coefficient, the features of the manifestation of the effect of economies of scale for 106 network and non-network enterprises were determined, taking into account the organizational life cycle of the development. It was revealed that, despite the ephemeral nature of the economies of scale, network enterprises are characterized by longer nature as a component of the synergistic effect of production activities and a decrease in costs, regardless of the development cycle of the organization. The results obtained can be useful as a basis for strategic planning in business integration.

The article aims to substantiate the relationship between the components of corporate social responsibility in business (CSR) during the economic integration of the GUAM member countries on the principles of sustainable development. We used the questioning to determine the structural elements of CSR of the GUAM member countries and econometrically analyzed the level of development of CSR for each country. The GUAM countries' hierarchical structure of CSR business was established using the Granger causality test and the graph method. This study proves that in times of crisis, along with economic responsibility, a fundamental role is played by national responsibility in ensuring justice, equality, and peace (for Georgia, Azerbaijan, and Moldova). And in the conditions of a full-scale war (in the example of Ukraine), national responsibility, responsibility in ensuring justice and equality, and peace are more significant than economic responsibility. The conclusions obtained are practical and may help develop strategies for effective economic cooperation between countries within the framework of GUAM.

The urgency of the research forms the complex of agricultural sector productivity problems, employment level reduction problems, low wages level, and land productivity reduction. The article is devoted to searching for agrarian sector development directions, which promotes steady economic development based on identified problems. The research aims to develop proposals for solving the main agro-sector problems, which contribute to sustainable economic growth. The article develops the methodology of analysis and uses statistical analysis, probability theory, and generally scientific methods of knowledge. The study brings evidence of the leading hypotheses proposed and the table in the “problem-solution” format. It is proved that the agriculture of Ukraine has a heavy influence on the economy and employment. Agriculture is characterised by instability, low wages, and increased land for growing plant products, while livestock farming is in decline. The following methods are used to solve the problems: market transformation on finished food-product, diversification of production, de-shadowing of the sector, agriculture automation increase, land reform controlling, stimulating farming state programmes. The originality of this study lies in the authors’ sustainable development analysis methodology through the agricultural sector growth. The practical significance of the study lies in the possibility of implementing recommendations at the macro- and microeconomic levels. A further research field forms the automation processes in agriculture available to small and medium-sized farmers

In a post-industrial society, the analysis of human abilities to work, their formation, reproduction and effective functioning is becoming increasingly important for achieving social and economic well-being. In the realities of globalization and total informatization, the figure of a person with his knowledge, creative and intellectual abilities comes to the fore. There is a reorientation of economics from the use of labor resources to the problems of creating a qualitatively new workforce, which takes the form of human capital. The concept of human capital testifies not only to the crucial role of man in the socio-economic system of post-industrial society, but also the need to invest in man, his education, training, health and livelihood, which are now priorities not only for individuals but also various government projects and programs. The state of human capital development is measured using the human capital index, which is calculated for each country separately.  In contrast to other studies, the article focuses on the development and importance of human capital in the realities of post-industrial society. Namely, the concept of human capital in the realities of post-industrial society is considered, the state of human capital development in modern conditions is analyzed, the influence and challenges of post-industrial society on human capital development are studied and the method of comparative analysis is applied.
