In the era of digital intelligence，building the ecological dominance of leading-chain enterprises is the key driver in the security and high-quality development of a chain industry. Drawing on the resource concerto theory，this paper conducted a longitudinal case study of Sany Group to explore the evolutionary mechanisms involving digital intelligence empowerment，resource orchestration，and ecological dominance of leading-chain enterprises. The findings revealed that digital intelligence exerts a three-dimensional empowering effect on enhancing the ecological dominance of leading-chain enterprises，manifested through organizational breakdown，cross-border integration，and dynamic adjustment. The leading-chain enterprises cultivate their ecological dominance by adopting a heterogeneous approach in different stages. By framing resource concerto as a proactive capability for resource management，leading-chain enterprises achieve a positive feedback loop in the industrial chain ecology through a combination of "whole machine entry and high flexibility"，"strategic cooperation and vertical integration"，and "perfect ecology and three-dimensional co-evolution". Furthermore，the leading-chain enterprises have undergone an evolutionary process evolving from point-based initiatives to network-centric integration to establishment of ecological dominance. Specifically，the leading-chain enterprises form a driving force of technological innovation，product market guidance，and resource integration in the industrial chain ecosystem through three modes，namely，point breakthrough，chain collaboration，and ecological integration. This research has revealed the resource concerto mechanism of the leading-chain enterprises during the process of the evolution of the ecological dominance empowered by digital intelligence，and it will provide theoretical guidance and practical implications for the digital transformation of industrial chains，dynamic resource management，and cultivation of the ecological dominance of leading-chain enterprises.
