New Models of Economic Growth: Endogenous Core, Institutional Shell, and Quality Filters

The article examines the transformation of theoretical and applied approaches to the study of economic growth in the context of digitalization and sustainable development. The relevance of the study is determined by the need for the Russian economy to transition to a new growth model focused on quality, innovation, and human capital. The current challenges of global competition, technological restructuring, and institutional uncertainty require a rethinking of traditional sources of economic growth and the development of a comprehensive methodological framework.To develop a theoretical and methodological foundation for a new model of economic growth that corresponds to the contemporary challenges of digital transformation and sustainable development.The research employs methods of analysis and synthesis, systemic and structural-functional approaches, as well as comparative and statistical analysis. The empirical part is based on official statistical data. The application of a systemic approach made it possible to construct a conceptual framework — the “core — shell — quality filters†model — reflecting the interrelation between endogenous, institutional, and digital, and environmental factors of growth.The study systematizes modern models of economic growth and identifies the key directions of their evolution — from exogenous to endogenous and institutional concepts. It is established that the core of modern models consists of knowledge, innovation, and human capital; the institutional shell determines the conditions for realizing their potential; and the quality filters represent ecological sustainability, social inclusiveness, and digital transformation. The empirical analysis of the Russian economy confirms the relevance of shifting from an extensive to an innovation-driven and digital type of growth focused on productivity enhancement, technological renewal, and human potential development.The formation of a new model of economic growth in Russia requires the integration of digital, institutional, and human factors into a unified development strategy. Priority should be given to improving human capital quality, stimulating innovation, strengthening institutions, and creating conditions for sustainable technological advancement. The transition to such a model will ensure the long-term competitiveness and stability of the Russian economy and promote the concept of qualitative growth based on productivity, social well-being, and ecological balance.
