The main idea of the study is to substantiate the dependence of financial and economic indicators on the efficiency of the use of land and resource potential in the structure of land use in European countries. Research is aimed at determining the influence of the land use system on the sectoral components of the economy of European countries. To achieve the goal, land use was grouped taking into account the types of economic activity and institutional sectors of the economy. Typification of land uses was carried out, taking into account the types of economic activity and institutional sectors of the economy of countries, and the corresponding types of land uses were formed, namely, food-forming, ecologically stabilizing, social-infrastructural, production-commercial - economic-forming. The proposed grouping system consolidated the following types of economic activity: forestry, agriculture, construction, industry, transport, trade, IT, scientific and technical, financial and insurance activities, administrative activities, defense, government, management, education, health care and social services, other services (taxes, arts, entertainment and recreation). As part of the study, the relationship between economic indicators of profitability (average GDP per unit area) and the use of land resource potential was identified, taking into account the institutional sectors of the country's economy. The conducted analysis demonstrates to what extent the income of a certain sector of the economy depends on the area of land use, which participates in the formation of economic benefits. Based on the circle-centric model, it was established that the increase in economic efficiency from the use of land-resource potential is proportional to the distance from the centre of the model (mainly food security) to the top (economy-forming industries of production).

This article proposes a balanced approach to the management of forest resources in Ukraine, based on a mathematical model developed using discrete mathematics. The algorithm of our study involved the following stages: 1) delineation of the spectrum of factors that characterize the ecological, economic, social processes of using forestry lands; 2) development of an economic system for the use of forest resources, with the simultaneous scientifically based establishment of interrelationships between the elements of the system; 3) calculation of the matrix of coefficients of pair correlations, which substantiate the relationships between the elements of the economic mechanism of the rational use of forest resources; 4) optimization of the economic graph of the use of forest resources, by distinguishing the key and secondary elements of the system; 5) economic and mathematical modeling of the rational use of forest resources. In order to apply the obtained calculations at the applied level in rational use of forest resources, we proposed appropriate strategic directions for the use of forest resources depending on the degree of impact on the environment. On the basis of the proposed management approaches of rational use of forest resources, we have developed mathematical models that allow to analyse the effectiveness of applying one or another strategy. The adequacy of the developed regression equations is confirmed by the coefficient of determination, Fisher (F) and Durbin-Watson (DW) tests. The developed mathematical models allow tracking the change of modeling indicators depending on the factor criteria and establishing their regularity. The article analyzes the use of forestry land in Ukraine based on two management approaches: an ecocentric approach and a balanced approach. The results show that the ecocentric approach can minimize the ecological situation in the short term but may negatively affect the development of the economy of nature use in Ukraine. The balanced approach, on the other hand, is the most adaptive for sustainable development. To ensure the balanced use of forest resources, the article outlines several conditions, including the regulation of market mechanisms, reduction of the anthropogenic impact, improvement of the ecological situation, and development of state programs. Fulfilling these conditions is mandatory to ensure the maximization of economic benefits from the use of forestry land with the formation of a favourable environment and the promotion of solutions to social problems of the population. The proposed approach can have positive consequences in regions where the level of forest production is low and the use of forest resources is unprofitable. [ABSTRACT FROM AUTHOR]
