A research framework is formed by the semantics of the “green” macrosystem, supported by a methodological approach, data analysis, and forecasting, with a focus on the dynamics of transition to a qualitatively new state. The purpose of the work is to develop conceptual provisions and methodological tools for assessing the implementation of the concept of a “green” macrosystem. Applying methods of system analysis, content analysis, formalization, statistical analysis (technologies of knowledge discovery in databases and time series analysis), and discriminant analysis contributed to achieving the goal. As a result of the research, the categorical apparatus of a “green” economy was clarified by outlining narrow and broad approaches to defining the “green” macrosystem; the author’s method of assessing the implementation of the concept of the “green” macrosystem was modified by expanding the list of factors of greening the economic system, transforming the condition of the “green” corridor to calculate the developed dynamic coefficient of transition to the concept of the “green” macrosystem (DCGM), and adapting the method to the macrosystem level; the regularities of a transition to the concept of a “green” macrosystem were revealed. The novelty of the study lies in the proposal of an integral DCGM indicator, which avoids the problems of normalization, weighting, and loss of relevant data, incorporates the determinants of the “green” economy (natural resources and pollution), and relies on available data. The formulated provisions develop the theoretical basis on which to transform the macrosystem to the “green” concept and can be taken into account in the implementation’s framework of strategic planning documents for the greening of production and economic systems.

Under the conditions of sanctions restrictions, Russia’s modern macroeconomic system is aimed at technological development, digitalization, sustainable development and greening of production and economic systems. The key problem of the functioning of economic systems is the limited resources, which determines the emergence of “bottlenecks” and queues. As a result, this affects the efficiency of the entire system and its competitiveness. One of the key conditions for achieving the goals of sustainable development is the development of nature-like technologies and their introduction into industry. The purpose of the study is to identify the theoretical aspects of nature-like technologies, to identify their potential for implementation to achieve sustainable industrial development. The scientific origins of the concept of developing the topic of nature-like technologies are analyzed, and the categories “nature-like technologies”, “nature-inspired algorithms”, and “nature-inspired systems” are defined. The principles of nature-like technologies that contribute to solving environmental problems, resource independence, economic efficiency, and technological development are summarized. The transformation of traditional production systems into mesosystems by analogy with natural ecosystems is considered. It is proved that this approach, which underlies the closed-loop economy, allows us to go beyond the introduction of individual “green” technologies and achieve a synergistic effect. To systematize the analysis, a classification of nature-like technologies is proposed and the main directions of their use in industry are identified. The following conclusions are drawn: the introduction of nature-like technologies gives a measurable and significant effect in three areas of sustainable development: 1) economics – reducing costs, creating new value; 2) ecology – reducing emissions, optimizing resources; 3) social sphere – creating safe working conditions and a favorable environment for human life and health. The economic effect of the introduction of nature-like technologies is one of the key drivers of their scaling. When making managerial decisions, it is necessary to consider that the introduction of nature–like technologies is a strategic investment in ensuring the competitiveness of the mesosystem and its resource independence. At the level of the country’s top leadership, it is necessary to develop and implement incentive measures for projects that implement the principles of nature-like technologies at the system level.

The relevance of the study is determined by the need to improve standard business models in the context of economic transformation and management systems, where non-traditional new types of managerial activity are becoming more important in connection with ensuring resource efficiency, one of which is the concept of the best available technologies. The aim of the study is to substantiate the role of BAT in ensuring resource conservation in the industrial sector, and the importance of standardization of business processes of BAT im-plementation. The combination of modern scientific approaches used in the study, in particular the use of methods for establishing cause-and-effect relationships, formalization, systematic and comparative analysis, generalization, formed the methodological basis of the study, and allowed to identify problems, patterns and directions for ensuring the implementation of the concept of the best available technologies. To achieve this goal, strategies for increasing the resource efficiency of industrial enterprises aimed at ensuring sustainable economic development are analyzed; theoretical approaches to determining the essence and role of BAT in ensuring resource conservation in the industrial sector. The significance of the development and implementa-tion of models and concepts of sustainable development of enterprises, including support for the creation of modern domestic equipment is substantiated. The stages of standardization of business management pro-cesses within the framework of the BAT concept are defined, providing a resource-saving strategy by reducing costs and the share of fuel and energy resources and raw materials in the cost of production. It is concluded that the creation and introduction of new technologies and innovative materials for the domestic industry is a necessary condition for the transition from traditional production models to resource-saving production sys-tems, which will contribute to the development of scientific and technological progress and increase the effi-ciency of resource-environmental measures.

With the tightening of environmental regulations, the need to identify tools that foster the development of sustainable systems is growing. The shift toward closed-loop, bio-like systems promotes the creation of nature-inspired systems. However, the transformation processes and toolkits vary across meso-level systems with differing economic activity. This research reveals the patterns of formation and develops governance models for the evolution of nature-inspired systems, considering the specifics of digital transformation and innovative activity in ensuring environmental security. Methodology includes the following: correlation and regression analysis, factor and cluster analysis, along with automated neural network simulations. The study resulted in the expansion of conceptual frameworks for “nature-inspired system” formation; revealed dependencies between the formation of a nature-inspired macrosystem and mesosystems, while identifying growth hotspots for nature-inspired systems in Russia; identified the priority determinants of nature-inspired mesosystem formation; proposed a composite index (DNIS—Development of a Nature-Inspired System) to assess the cumulative impact of determinants and evaluate ecological performance responses; and developed a typology of regional mesosystems based on economic/ecological performance and “green” technology adoption, enabling differentiated approaches to guiding nature-inspired system development. The findings presented in this study are recommended for applications in improving regional socio-economic development programs.

Restructuring, redesigning or designing the organizational management structure on a scientific basis at domestic petrochemical enterprises are tools for improving the management system in the context of transition to new management standards, which contributes to the most effective achievement of goals. The article summarizes and analyses methods and approaches for designing organizational management structures and methods for their evaluation. In the development strategy of petrochemical enterprises aimed at resource conservation and the development of new petrochemical products, flexible organizational management structures are recommended, the design of which requires the use of a set of methods with the integration of the advantages of each of them. For proper management decision-making, it is necessary to develop a balanced system of indicators, in connection with which the author proposes the key indicators that characterize the effectiveness of the management system – technological, managerial, economic. The paper develops the functional model of modernization of the organizational management structure according to strategy of development of the enterprise based on the IDEF0 methodology. The study proposes the model of lean strategy for the development of the organizational structure of petrochemical enterprise management, as the integration of business strategic management systems, production organization and personnel training, based on the project management approach.
