The article examines how corporate strategy is formed in conditions of heightened environmental uncertainty and the rapid digital transformation of business, against the backdrop of an emerging socio-economic and ecological reality. It reviews the most relevant contemporary concepts and approaches to corporate management in an increasingly digital and socially oriented economy. In this new context, the structure and content of strategic components are substantiated by conceptualising the corporation as an ecosystem with both an external environment and an internal configuration that transforms various types of resources through interconnected processes. The study argues for the necessity of shifting from classical long-term planning toward adaptive strategizing that combines the principles of socio-ethical marketing with the flexibility afforded by digital technologies. The close interrelation between corporate strategy and the business model is emphasized. It is proposed that the corporate business model be examined and shaped through G. Kleiner’s tetrad framework, which comprises the object, environment, process, and project subsystems. From this perspective, strategic planning is interpreted as the identification and coordination of areas of activity in accordance with socio-ecological and economic conditions. Strategy implementation, in turn, presupposes a project-based foundation and the spatial-temporal aggregation of smaller interrelated initiatives. The article also proposes that the effectiveness of corporate strategy be assessed through the evaluation of how efficiently capital, working, labor, ecological, and marketing resources are utilized, thereby providing an integrated basis for diagnosing strategic performance in a transforming external environment.
