Ensuring the complementarity of enterprise potential development as an innovative basis for the circular economy model

The article substantiates that the complementarity of the development of the enterprise’s potential is a key innovative factor in forming a circular economy model. It has been proven that complementarity is a system-forming principle of strategic management, allowing synergy between different types of resources, functions, institutions, and partners. Modern forms of complementarity are analyzed: inter-resource, functional, institutional, and inter-organizational. Based on the enterprise’s system approach and resource theory, a structural-functional model of complementary potential development is proposed, including integrating resource-material, human, organizational-informational, innovative-technological, and partner blocks. The mechanisms for ensuring complementarity are revealed: strategic coordination, eco-design and digital compatibility, internal interaction of potential, inter-partner coordination, and management of complementary risks. It has been established that their implementation contributes to increasing the efficiency of management decisions, strengthening the environmental responsibility of business, and forming competitive advantages. The use of integrated indicators is proposed to assess the level of complementarity, particularly the digital integration index, structural interaction coefficients, and compliance with strategic priorities. The importance of digital infrastructure and management education as factors of the circular transformation of enterprises is emphasized. The results can be used to develop sustainable development policies, create circular clusters, and increase enterprises’ adaptability to external challenges. The practical significance of the complementarity principle is manifested in the ability to ensure the effective functioning of the management system, optimize internal processes, reduce dependence on external resources, and form new market offers with high added value. The proposed mechanisms for ensuring complementarity – in particular, strategic alignment, digital compatibility, inter-partner coordination, and complementary risk management – create the basis for forming an adaptive, flexible, and innovative organizational structure.
