Abstract: The article explores the development of entrepreneurial entities under conditions of socio-economic instability, which is of particular importance since instability is increasingly becoming a permanent feature of the modern economy. Global processes that combine cyclical economic crises, technological breakthroughs, political transformations, and cultural changes create new challenges for entrepreneurial activity. Under such conditions, classical approaches to the study of entrepreneurship, formed mainly on the basis of stable economic systems, demonstrate a limited ability to explain the real dynamics of development. This has highlighted the need to update the theoretical and methodological foundations and to search for new conceptual solutions capable of reflecting the complexity and multi-factor nature of the contemporary entrepreneurial environment. The article emphasizes that despite the availability of substantial scholarly contributions, a review of the literature reveals the fragmentary nature of existing research. Many studies focus on individual aspects—innovation, institutional transformations, or the resource potential of entrepreneurial structures. However, comprehensive investigations that integrate different approaches and enable the explanation of development in the integrity of its manifestations remain insufficiently represented. The absence of such integrated models reduces the explanatory value of the academic discourse and limits opportunities for the practical application of results in the strategic management of entrepreneurial entities. The research objective is defined as the systematization of conceptual approaches to entrepreneurial development, the identification of their key characteristics, and the determination of integration prospects, which will ensure the formation of a more comprehensive vision in the context of socio-economic instability. The main material is presented as an analysis of three leading conceptual orientations. The innovation approach views entrepreneurship as a process of continuous renewal, based on the implementation of technological innovations, the creation of new business models, and products that provide competitive advantages. The institutional approach emphasizes the influence of formal rules and informal norms that establish the «rules of the game» for entrepreneurs, setting boundaries while simultaneously opening opportunities for adaptation. The resource-organizational approach highlights the importance of the internal potential of entrepreneurial structures, their competencies, managerial decisions, and ability to design organizational models that ensure flexibility and resilience in a turbulent environment. It is concluded that the isolated application of each approach does not allow for capturing the full range of modern entrepreneurial development. Their combination creates the prerequisites for forming a holistic scientific vision that integrates innovative, institutional, and organizational aspects. The debate lies in defining the optimal forms of integrating these approaches and outlining the boundaries of their applicability. In the long term, integrated conceptual models can provide better predictive capacity regarding entrepreneurial development trajectories and enhance the practical value of research results for designing strategies of resilience, adaptation, and competitiveness of businesses under uncertainty.
