In the context of digital transformation and global competition, the formation of business ecosystems is becoming an important factor in increasing the competitiveness of national economies. Modern economic systems need to integrate innovative technologies, digital platforms and scientific developments for sustainable development and adaptation to new challenges. In this regard, the study of business ecosystems and their impact on economic growth is becoming particularly relevant. The research is aimed at analyzing the role of business ecosystems in increasing the competitiveness of the economy, identifying their key characteristics, development factors and mechanisms for integrating digital technologies. The research examines the theoretical aspects of the formation of business ecosystems, their evolution, the impact of digital technologies on their development, as well as international experience in building effective business models. The key features of business ecosystems, their classification, mechanisms of interaction between participants and the role of the state in stimulating their development are analyzed. Special attention is paid to the study of information technology as a driver of ecosystem business growth and factors of economic digitalization. The main conditions for the effective functioning of business ecosystems, the key directions of their development, as well as the challenges and risks associated with the introduction of digital technologies are identified. Examples of successful ecosystem models in world practice are considered. It is assumed that the results of the study will make it possible to form recommendations for the development of business ecosystems in the context of digital transformation, identify the most promising areas of investment in innovative technologies and assess their impact on the competitiveness of the economy. The development of business ecosystems in the digital economy contributes to the growth of countries' competitiveness, stimulates innovation and improves business conditions. Government support, investments in the IT sector and the creation of favorable conditions for private business are key factors for the successful development of business ecosystems and the digital economy as a whole.
