The dissertation is devoted to the development of theoretical, methodological and practical provisions on the formation of the mechanism of sustainable development of machine building enterprises. Improved categorical and conceptual apparatus of economic research, in particular the concept of the mechanism of sustainable development of enterprises is treated as a dynamic system of interrelated and interdependent elements, which, receiving resources and information from the external and internal environment, influences them using certain principles, "skills" and " experience, and aims to ensure balance and balance in obtaining economic, social, environmental and energy performance, depending on the strategic hey enterprise and sustainable development. The above definition, in contrast to the existing ones, implies the application of a bioonomic approach, which allows us to view the enterprise as a system capable of learning, self-improvement and self-development, which is fundamentally important in today's changing conditions of enterprise functioning. The substantive characteristics of the sustainable development mechanism have been generalized and expanded, namely the components of the system of sustainable development of machine-building enterprises from the standpoint of bionomy have been expanded, in particular, such tools of the sustainable development mechanism as "skills" and "experience" have been added that allow to take into account the formation of the sustainable development mechanism. the ability of the enterprise to learn and accumulate information, which ensures the effectiveness and efficiency of management decisions and business processes, as well as the exchange in information with the environment. Existing approaches to the classification of mechanisms of sustainable development are analyzed and summarized and criteria for classification by developmental direction (evolutionary and individual) and approach to functioning (bionomical or physical) are added. The system of principles of the Sustainable Development Mechanism is researched and generalized and the principles of the ability to learn (the ability of an enterprise to acquire, accumulate, transfer and retain knowledge about sustainable development, environment, external and internal factors, forming the experience that should facilitate the more efficient use of information in the process of activity are highlighted ) and automaticity (bringing certain mandatory measures to receive and transmit information, resource and energy savings, etc. to the off-the-shelf machine be brought further attention and effort to optimize the use of time). It is determined that each enterprise has its own special mechanism of sustainable development, which differs from the others in terms of goals, tools and systems of provision. The mechanism of sustainable development influences the results of activity of enterprises, respectively, the more effective the mechanism is, the more sustainable the development of the enterprise will be. The system of factors influencing the formation of the sustainable development mechanism has been generalized and expanded, the factors of the ability to counteract the disturbance of the external environment, the behavioral factors, the size of the enterprises, the provision of the functioning of the mechanism, which take into account the peculiarities of the functioning of the sustainable development mechanism in its relationship with the external environment. The algorithm of realization of the mechanism of sustainable development is developed which gives the opportunity to change stages depending on the conditions of functioning of the enterprise, influence of external and internal factors, in particular setting of tactical goals or diagnostics of available resources and problems, which allows to adapt the proposed algorithm to any enterprise. It is proposed to introduce the tools of forming a mechanism of sustainable development in machine-building enterprises using a balanced scorecard, which allows to identify important areas of sustainable development and to monitor the achievement of goals for sustainable development subsystems. The methodological approach to the estimation of the level of sustainable development of enterprises is improved, which allows to determine the degree of achievement of goals by calculating the integral indicators on subsystems of sustainable development and the overall integral indicator of sustainable development of the enterprise. On the basis of integral indicators of sustainable development by subsystems a four-dimensional indicator of the level of sustainable development has been developed, which allows to form enterprise development scenarios in order to determine the most expedient allocation of resources between subsystems of sustainable development of the enterprise.
