Purpose. Justification of the methodological approach to the strategic management of reserves for the growth of economic security of enterprises and the provision of appropriate recommendations for this purpose (by the example of METINVEST HOLDING LLC, mining enterprises of the Kryvyi Rih iron-ore basin). Methodology. A system of the following general scientific and special methods was used to achieve the research goal: mathematical and statistical methods to assess the economic security of selected enterprises; methods of correlation and regression analysis to form a system of indicators of the greatest impact on the economic security of the enterprise; econometric modeling methods to predict the value of the integrated indicator of economic security of the enterprises; structured system method to determine the reserves of economic security growth for each business structure; matrix methods to form a strategic field and determine the place of each of the enterprises under study within this field. Findings. The authors have analyzed the dynamics of the economic security of mining enterprises in the Kryvyi Rih iron-ore basin from 2014 to 2018. Multivariate correlation and regression models have been built that allow determining the calculated (maximum possible) value of the integral indicator of the economic security of the enterprises under consideration. After comparing a defined (actual) and calculated value of economic security of the studied elements of the economic security system, its growth reserves for each business structure have been determined. The economic security trend of each mining enterprise in the Kryvyi Rih iron-ore basin until 2021 has been determined, which is characterized by an upward or downward slope of the economic safety values of the enterprises under consideration, predicted by the models and the prospect of achieving the maximum value of it. The resulting characteristics of the economic security value of enterprises predicted based on the trending models make it possible to build a strategic field of basic strategies according to Michael H.Mescon and determine the position of each enterprise within it. Originality. The authors offer a methodological approach to the strategic management of the growth reserves of the economic security of the enterprise, which is defined as a result of the study that is based on the improvement of the instrumental apparatus, which, in contrast to the existing ones, allows synchronizing both temporal and spatial parameters, significantly increasing the efficiency of managerial decision-making. Practical value. The methodological approach to the strategic management of the use of reserves for the growth of the economic security of the enterprise allows synchronizing the strategic management of the enterprise with the modeling of the economic security level. This ensures the economic security of the enterprise to a fuller extent.

The article deepens the theoretical and methodological foundations of strategic management of determining and achieving competitive advantages of the enterprise. To objectify the evaluation parameters of competitive advantages, a technique of competitive advantage analysis is proposed, which includes the following sequence of stages: determination of the basic strategy of enterprise development by the Thompson-Strickland model, determination of the competitive strategy of enterprise development by the Porter model, analysis of the competitive forces of the enterprise by the Porter model, systematization of components strategic potential of the enterprise according to the Borden-McCarry model; and determination of sustainable competitive advantage of the enterprise. According to the proposed method of analysis of competitive advantages of the enterprise, the following components of strategic potential are attributed to the directions of its strategic focus: product, price, promotion, place, people, process, physical environment. Most focus is on sustainable competitive advantage. According to the results of strategic analysis of a subsidiary's enterprise, its stable competitive advantage is formed. The method of analysis of competitive advantages of the enterprise is described. The essence of forming a focus strategy as a way of achieving competitive advantages of the enterprise is revealed. The disclosure of formation of competitive advantages of the investigated enterprise is improved. The technique of the analysis of competitive advantages of the enterprise through the mechanism of focusing on them is offered. The strategy of focusing the enterprise as a way to achieve its competitive advantages has been formed. The strategy of focusing of the conditional enterprise as a way of achieving its competitive advantages is formed. It is determined that the conditional enterprise has a strong competitive position and slow market growth. A competitive product focus strategy means leading the niche in the services provided, focusing all of the conditional enterprise's efforts on the quality of the services provided.

Article proposes methodology for assessing state of energy interests’ security of enterprises, which allows determining periods of achievement of indicators of their liminal values, taking into account the rate of change. Application of methodology allows concluding need for managerial intervention, decision-making and taking appropriate measures to improve the security of energy interests in general and its components: security of energy efficiency and security of energy supply. As a result of calculations, it was found that energy security indicator for all mining enterprises of Ukraine in 2018-2019yy was 1, which corresponds to very high state of this security. A similar state of energy efficiency security in this period took place only at JSC Southern GZK, as the indicator of this security is also equal to 1. At all other surveyed enterprises, energy efficiency security indicators deteriorated. The worst state of this security was in 2019 at PrJSC InGZK. Four groups of measures to ensure security of energy interests of mining and metallurgical enterprises are highlighted. The first group includes improving state regulation of the energy market. The second direction includes reorientation of production apparatus and introduction of resource-saving technologies that will dramatically reduce energy and fuel consumption. The third direction is more active participation in bidding on energy exchange. The fourth area includes attracting and training employees in new competencies and professions necessary for development, implementation and implementation of innovative energy-saving technologies in enterprises and transition to energy business model.
