The relevance of this study is due to the lack of a scientifically developed concept of the formation of sustainability indicators for small enterprises operating in the environmental field. The purpose of the study is to develop a mechanism for the economic sustainability of environmental organizations, which is based on competition, centralization of management, and business activities. In addition, the paper analyzed the modern theory and practice of managing production structures, studied the main factors affecting the system of indicators of the organization’s sustainability. A methodology that allows for diagnostics and assessment of the sustainability of an enterprise is proposed. The financial mechanisms that ensure the process of financing environmental activities are studied.

The purpose of this paper is to improve methodological provisions for the organization and practical implementation of the interaction of public and private enterprises in order to increase the efficiency of their activities, taking into account mutual interests. A model has been formed for assessing the efficiency of overcoming administrative barriers by entrepreneurial entities, which is based on taking into account the price and time for entrepreneurs to overcome problems in running their business. The system of indicators for the development of interaction between public and private enterprises is structured, which allows analyzing trends in the development of interaction processes in a wide range of areas: resource availability, administrative barriers, development of competition, ensuring the security of business, information openness, innovative development.

The aim of this study is to develop methods to reduce the risk load on investment and construction enterprises based on the principles of self-organization. A model of formalizing the vector control function in the process of identifying a company in the investment and construction sector as a complex self-organizing system is proposed. A model of vector optimization of risk reduction for investment and construction companies has been formed, taking into account the difference in their interests and capabilities depending on the degree of integration. The optimality criteria of the model make it possible to reduce the risk coefficient by reducing the potential loss, increasing profits, and optimizing the ratio of own and borrowed funds. As a result of the study, a method was developed for the formation of a risk reduction mechanism in investment and construction companies, which is a set of step-by-step managerial actions for identifying risks and conducting anti-risk measures.

The purpose of this paper is to develop practical recommendations for managing the innovation activities of small and large enterprises in the face of increasing competition. As a result of the study, the peculiarities of managing the innovation activity of a small manufacturing enterprise based on the application of the diffusion of innovation method for such management functions as management, production, marketing, and human resources have been identified and generalized. A mechanism has been developed to implement the scientific and technical policy of small manufacturing enterprises, the key feature of which is the possibility of introducing innovations. An algorithm for the formation of the most optimal program for the innovative development of a small manufacturing enterprise is proposed, within the framework of which the innovation process is proposed to be considered in the form of logically indivisible organizational, managerial and technological operations, taking into account the assessment of the size and form of the required resource support for each operation, as well as its economic efficiency. As a result of the study, a technique was obtained that allows determining the most optimal program of innovative development based on the analysis and comparison of their necessary resource support and economic effect from implementation.

As a part of the study, the problems of forming the investment strategy of energy companies were considered. Possible ways of choosing the most rational forms of investment in the assets and a comprehensive assessment of the strategy’s effectiveness were proposed. A methodology for the qualitative and quantitative assessment of the investment strategy for the development of an enterprise has been developed by analyzing the Cobb-Douglas production function. In the paper, when solving specific problems, general economic methods of analysis, probabilistic and statistical methods, the method of expert assessments, and methods of system and comparative analysis were used. The practical application of the proposed assessment methodology is considered on the example of comparing two options for the investment strategy of an enterprise operating in the field of energy processing.
