Characteristics of the Finnish education system: impact on social life

In this article, the authors highlight the achievements of the Finnish education system, the most successful at the moment, in all countries of the world. The practical significance of the research for the institutions responsible for education in the Republic of Moldova and Israel, about the activity the authors are informed, is significant. In both states we have fundamental problems with reforming the education system, developing and implementing new curricula. The authors emerge from the thesis about applying the principle of learning continuity, complete assimilation of information about the researched fields. Initially, this principle was realized in Finland. In conclusion, the authors mention: the country with a high level of economic development, with an economy open to inclusion, is distinguished by a level of education, a higher technological level. In such a country, the population benefits from advanced infrastructures, a diversity of quality services, long life, and a low birth rate.

Study on the Impact of Energy Poverty on Energy Efficiency of Construction Industry: Mediating Role of Energy Consumption Structure

In the process of continuously advancing urbanization, the energy efficiency of the construction industry, as a pillar industry of the national economy, has attracted much attention. The imbalance of regional economic development, the difference of regional resource endowment, and the incomplete energy infrastructure in some areas lead to the prominent problem of energy poverty in China. Based on the panel data of 30 provinces and cities from 2008 to 2017, this paper calculates the energy poverty index and the energy efficiency of the construction industry. Using OLS, Tobit, Probit, and other estimation methods, this paper analyzes the internal relationship between energy poverty and the energy efficiency of the construction industry, the mediating role of energy consumption structure, and the moderating effect of technological level and marketization degree. The results show the following: There is a negative correlation between energy poverty and the energy efficiency of the construction industry (Husnain, ENERG POLICY, 2021, 157). The energy consumption structure plays a partial mediating role in the impact of energy poverty on the energy efficiency of the construction industry (Li, CHEM ENG J, 2021, 408). It means that energy poverty inhibits the optimization of the energy consumption structure, and through this process, it also inhibits the improvement of the energy efficiency of the construction industry. The technological level and the degree of marketization play a moderating role in the main effect, which can weaken and strengthen the negative impact of energy poverty on the energy efficiency of the construction industry (Gajdzik, ENERGIES, 2021, 14).

DIRECTIONS OF IMPROVING THE LEVEL OF ENTERPRISES COMPETITIVENESS IN THE MACHINE-BUILDING INDUSTRY OF UKRAINE

The article determines and systematizes the existing obstacles to the development of competitiveness of enterprises in the machine-building industry of Ukraine. One of the most important problems facing the domestic economy is to ensure stable economic growth not only in the raw materials industries, but above all, in the leading industries of the industrial complex, whose center of gravity is the machine-building industry. Machine-building complex – one of the leading in the industry of Ukraine, which integrates a system of research, design and technological organizations; It is engineering determines the socio-economic and technological and technological level of state development, the competitiveness of its productions. Effective functioning and maintenance of a high level of competitiveness, is important for modern Ukrainian machine-building enterprises. The article investigates the main constraints of competitiveness of enterprises of the machine-building industry of Ukraine, which related to change, connections and competition.The development of mechanical engineering under the influence of various factors is not predictable, not by plans and programs, which are formed by governments taking into, account the needs of industrial products and the requirements of globalization of the world economy. It is accompanied by accumulation of problems that adversely affect the development and general condition of machine-building corporations. The situation is worsening with a decrease in the time span between global crises, which adversely affect the state of the national economy of Ukraine and the types of economic activity. Despite the negative trends that are observed in industry and in machine building, there is a possible directions of solving the existing obstacles and restrictions.

Technological Heterogeneity in Pig Farming: A Metafrontier Approach—Perspectives from Hungary and Poland

Despite remaining the most important type of animal production, pig production in Poland and Hungary declined after their accession to the European Union (EU) in 2004. This paper investigated the evolution of the technical efficiency of the pork industry in both countries. We applied stochastic frontier analysis, which takes into account heterogeneity in the production environment and production functions in both countries—true random effects, and a metafrontier model. We employed farm-level data from the Farm Accountancy Data Network sample during the period 2004–2015. Results illustrate the differences in production function in both countries and technological decline throughout the period of analysis. Furthermore, farms in Hungary were more technologically developed as well as less efficient in relation to the country frontier; however, the higher technological level resulted in generally greater efficiency in relation to the metafrontier. Our results suggest that different policy measures would be effective in the countries under analysis.

Institutional Principles of Building the Fiscal Mechanism for Regulating the Investment Development of the National Economy

The state, influencing the processes of organization of fiscal relations by forming institutions, directs the established fiscal relations, manages the channels and directions of fiscal flows, clarifies the proportions of financial resources distribution and thus regulates the investment development of the economy. Therefore, the aim of the study is to determine the institutional principles for building a fiscal mechanism, from which depends not only its effective functioning, but also the impact on investment processes in the national economy. In order to substantiate the institutional principles of building a fiscal mechanism for regulating the investment development of the national economy, general and special research methods were used (analysis and synthesis, induction and deduction, abstraction, analogy, theoretical generalization, etc.). The historical development of institutional theory is considered in the course of the research. Approaches to the interpretation of the meaning of “institution” concept are defined, their functions and characteristics are outlined. The essence and components of the institutional structure of the fiscal mechanism for regulating the investment development of the national economy are substantiated. As a result of the research it is proved that the institutional structure of the fiscal mechanism is four-level and includes the cognitive level, regulatory level, organizational level, resource-technological level. It is determined that at the present stage of development of Ukraine the institutional structure of the fiscal mechanism is formed, but its characteristics do not sufficiently correspond to the features, resources and tasks of regulating the investment development of the national economy.
