The paper reveals interrelations between the concepts “economic security”, “economic sustainability”, “development” and “competitiveness” of an enterprise. Based on their consideration, the paper enhances theoretical and methodological principles of establishing competitive innovation development and economic security of an enterprise. Unlike the existing ones, these principles provide for not only alternativeness but also equal significance when choosing between achievement of high levels of competitiveness, development and economic security. Application of the elaborated suggestions enables more objective formation of the policy of management of an enterprise’s innovation development under unstable conditions considering the industrial field and the market position of the enterprise. It is proven that essential elements of enterprises’ sustainable development include innovative activity, production provision, export of science-intensive products and development of high technology services, this providing for efficient levels of enterprises’ economic security and competitiveness. Under conditions of uncertainty, there are some basic functions of an enterprise aimed at enhancing its competitiveness and economic security including the following: achieving the optimal level of an enterprise’s resulting indicators and efficient “income-risk” ratio, innovative activity, ensuring the quality of an enterprise’s intellectual capital, environmental safety and meeting required social standards.

The article substantiates that achievement of certain economic security level set by management for the current time point is a necessary but insufficient condition of further development of the enterprise. When the mentioned condition is fulfilled, the degree of its personnel's innovation activity should also be considered. The article presents further development of the methods of assessing the level of the dependent part of economic security of the enterprise's stakeholders, including the personnel, which, unlike others available, is based on estimation of outstanding expenditures. Innovation activity of the personnel is determined to depend on their attitudes to innovations. The article presents a developed economic and statistic toolkit of assessing the personnel's probable attitudes to implementation of innovations considering the degree of recognizing the necessity of innovations and awareness of the enterprise's activities in terms of innovations. The level of probable (expected) attitudes to innovations is taken as a basis for a combined classification of particular personnel categories. The article suggests a matrix approach to determining the type of enterprise development based on comparison of the level of economic security for the current time point and the personnel's innovation activity.

The article presents the authors’ views on the essence of analysis of personnel innovative potential of an enterprise. Using a system approach, the analysis of personnel innovative potential is considered as one of the functions of the management system. The authors’ method of analysis of enterprise personnel’s innovative potential is suggested, within which the goals, tasks, an object and subjects of analysis, as well as stages of analysis of personnel innovative potential are determined. The sequence and essence of these stages reflect the authors’ view of the analytical procedures concerning the object of analysis and allow selecting relevant analytical tools considering the time domain, the structure of personnel innovative potential and other components. The choice of methods of analysis of personnel innovative potential is substantiated, their characteristic is given within the limits of this research.

The subject of the research is the processes of ensuring the competitiveness of the potential of mining enterprises based on certain key aspects of methodology and practice of rational management of investment distribution, which are inherent in the investment and innovation activities of subsidiaries within the parent company. The purpose and objectives of the study is to improve theoretical and methodological approaches to increase the competitiveness of the potential of mining enterprises on the basis of rational management of the allocation of investment resources in the process of their innovative development. Method (methodology). Solving issues of rational allocation of investment resources from the standpoint of proper competitiveness of mining enterprises is proposed to be carried out according to the method of optimizing multi-stage processes - the problem of dynamic programming of resource allocation between enterprises based on the principle of optimality R. Bellman. Results. As a result of research it is established that the most important criterion for optimizing the program of innovative development on the basis of rational distribution of investment resources is to choose the cost of sales, due to the dependence of financial performance of mining companies on total costs. The implementation of the proposed method of optimizing the allocation of investment resources is considered on the example of jointly operating in one company mining companies. Conclusions. Based on the generalization of research on theoretical and practical aspects related to improving the efficiency of managing the competitiveness of resource and production potential of mining enterprises, a methodological approach to prioritizing the allocation of investment resources in the context of innovation development working together in one company. The application of the developed methodological approach in practice allows the top management of large vertically integrated companies to rationally direct the allocation of investment resources to the stable innovative development of subsidiaries.

The article aims to determine the influence of the innovation potential of personnel on strengthening economic security of Ukrainian enterprises in the post-war period. The object of the article is the process of strengthening economic security of Ukrainian enterprises considering the use of innovation potential of their personnel. The study uses general scientific theoretical methods: generalization, explanation, grouping - to analyze economists’ views of the study object and draw conclusions of the content analysis of primary sources, analysis and synthesis - to clarify the main scientific categories of the study, substantiate new conceptual provisions. Four obstacles have been identified to the positive influence of the innovation potential of personnel on strengthening economic security which consist in the absence of an innovative component in the advanced training program for personnel of most Ukrainian companies and government institutions; an indicator related to the innovation potential of personnel in the regulatory legal acts of Ukraine on innovative development; joint projects of the state and private partners to increase the innovation potential of personnel; a relevant state body that would deal with strategic issues of cooperation with business structures and other private enterprises. The article proposes directions of solving the identified problems. The proposed directions are of scientific novelty and practical value and can be used in development of joint projects to strengthen economic security in the energy sector, construction, import substitution and other fields. Consideration of innovative competences, technical and professional potential will allow solving the issues of combating terrorism, cybercrime, protecting critical infrastructure, eliminating consequences of emergencies and environmental disasters, restoring activities of enterprises in various sectors of the economy.
