Abstract：The regional transformation in industrial structure and radical urbanization have led to indeterminant spaces of
multifarious dimensions in Chinese cities, which lack specific definitions and efficient utilization. These spaces,
referred to as “urban leftover space” in urban morphology studies, afforded considerable stock resources in response to
climate responsiveness and social sustainability. This study focuses on the formation factors and conceptual definition
of urban leftover spaces, taking Zibo as an empirical case. It introduces beneficial attempts made by the city to explore
the organic revitalization of these spaces. It comprehensively analyzes their characteristics through the adaptation of
existing resources, the introduction of new industrial formats, and the integration of public resources into sustainable
urban development. The research provides empirical references for unlocking hidden resources in fringe spaces and
achieving sustainable development in Chinese urban development.
