Abstract:     It is imperative to expedite the cultivation and advancement of an innovation ecosystem for marine ranches, underpinned by digital intelligence, to facilitate promotion of the high-quality development of the marine economy. The Hengxing Group was used as a case study in this paper, which employed the rooted theory approach to explore how digital intelligence technology reconfigures the elemental structure of the marine ranching innovation ecosystem. The study then went on to explore the process and characteristics of value co-creation in the marine ranching innovation ecosystem driven by digital intelligence technology. The study found that during the exploration period, enterprises concentrate on establishing digital intelligence innovation advantages and reinforcing value perception in digital intelligence through technology leapfrogging and strategic layout. During the linkage period, enterprises prioritize digital intelligence value reconstruction, thus expediting the development of digital intelligence infrastructure to achieve value chain optimization, and fostering the establishment of innovation consortiums. In the transformation period, enterprises attain ecological synergy and value co-generation through comprehensive refinement of operations and management and open innovation cooperation. The study has revealed the value of digital intelligence technology for the cultivation of innovation ecosystems in marine ranching, and it will provide some theoretical references and practical guidance for the high-quality development of the marine economy.

Key words: marine ranching, innovation ecosystem, digital intelligence drive, value co-creation
