The article is devoted to the issues of shaping and improving the conceptual approach to building a hybrid sharing platform for the ecosystem of youth social integration as well as facilitating environmental stress reducing actions on the territory. The sharing platform operation relies on the principles of sustainable development, long-term economic growth, social cohesion and reintegration, and environmental protection. These principles are embodied in the growth and development of regions exhibiting social strain, finding a balance between economic and social progress, in support for the social integration of youth and the empowerment of vulnerable population groups, especially young people, ensuring equal access to education, and environmental protection of territories. Application of a combination of such approaches to arranging a platform will ensure the implementation of innovative strategies for socioeconomic, educational, entrepreneurial and environmentally conscious activities; help to mitigate social tension by creating additional jobs, reducing unemployment, overcoming poverty and shaping modern, innovative active youth generation capable of creating their own business to improve the quality and standard of living. The key idea of this study is that integration into the university ecosystem of a new structure – the hybrid sharing platform for the ecosystem of youth social integration – will promote integrated interaction of interactive tools of the innovation chain of human capital development within a new paradigm. A new understanding of educational and innovation policy priorities and creating an appropriate institutional environment for effective ecosystem performance based on the hybrid sharing platform will contribute to further human potential development, enhancing professional, legal and environmental consciousness and awareness of youth subject to national priorities and global trends in research and technology, foster social and psychological reintegration of vulnerable groups of young people to active socioeconomic and labor activities.
