The primary aim of this research is to explore and analyze the profound and extensive impacts of sharing economy platforms on new entrepreneurial models within smart cities. This study seeks to provide a comprehensive understanding of how these platforms facilitate innovation and urban economic development. This study employs a qualitative approach through semi-structured interviews with 28 entrepreneurs, city managers, and ICT experts. Participants were selected using purposive sampling, and data were analyzed using qualitative content analysis. The results indicate that sharing economy platforms serve as powerful facilitators for promoting innovation, creating new job opportunities, and improving access to services in smart cities. These platforms effectively reduce entry barriers for new entrepreneurs and strengthen dynamic and creative entrepreneurial ecosystems. This study underscores that sharing economy platforms play a crucial role in the sustainable development of smart cities. They not only aid in stimulating economic growth and innovation but can also act as catalysts for change in traditional business models and promote a culture of collaborative entrepreneurship.
