Abstract:In order to explore the construction process of digital innovation ecosystem with traditional manufacturing enterprises as the core, Weichai was selected as the research object, and the longitudinal single case study method was used to explore the internal mechanism of meaning construction, resource arrangement and digital innovation ecosystem construction of core enterprises based on the perspective of cognitive-behavior combination. The findings are as follows: (1) Meaning construction and its cross-level transmission are the prerequisites for promoting the construction of digital innovation ecosystem, and the formation and transformation of meaning construction is the result of core enterprises adapting to changes in technology and needs in the environment. (2) The cross-level meaning construction starting from the leadership level of the core enterprise and the resource arrangement behavior triggered by it, as well as the interaction and collaborative evolution of the two are the core mechanisms to promote the construction of the digital innovation ecosystem. (3) Meaning construction iterates its own cognition by receiving feedback from resource arrangement, and finally realizes the development from ecological foundation construction to ecological sharing and then to innovative ecological sustainable development.
