ANALYSIS OF APPROACHES TO ASSESSING THE SUSTAINABILITY OF TECHNOLOGICAL DEVELOPMENT OF INDUSTRIAL INFRASTRUCTURE ENTERPRISES

The article examines and systematizes existing approaches to assessing the sustainability of technological development of industrial infrastructure enterprises in the face of increasing external constraints, technological turbulence and the transformation of global value chains. It is shown that in modern Russian and foreign scientific literature, the sustainability of technological development is interpreted from various conceptual positions — within the framework of theories of economic growth, dynamic abilities, technological security, financial, economic and environmental sustainability. The analysis revealed the fragmentation of the existing methodological framework, the orientation of most approaches to fixing the current state of the system and insufficient consideration of the process nature of technological development at the enterprise level. Special attention is paid to the specifics of production infrastructure enterprises, the technological development of which is of a derivative nature and is determined by the requirements of the basic consumer industries. It is proved that the macro-level indicators of technological development and security used in strategic documents have limited practical significance for assessing the sustainability of technological development of such enterprises. It is shown that financial, economic and innovation indicators mainly reflect the results of functioning, but do not reveal the internal mechanisms of sustainability formation. The article proposes a methodological rethinking of the sustainability of technological development of an enterprise’s production infrastructure as a dynamic system property that characterizes the ability to maintain a reproducible and adaptive trajectory of technological change under external constraints. Sustainability is interpreted as the reliability of the development trajectory, which makes it possible to integrate the provisions of reliability theory, system analysis and process management. The findings form the theoretical basis for the development of integrated indicator and process models for assessing and managing the sustainability of technological development of industrial infrastructure enterprises.
