Abstract: In the complex and changeable digital environment, capability reconfiguration has become an effective mechanism for digital enterprises to make full use of emerging digital technologies to achieve digital integration product innovation. However, how to perform capability reconfiguration to accelerate digital integration product innovation has not been fully revealed by existing research. DigiBird is selected as the case study object, to analyze the process and mechanism of enterprise capability reconstruction under different stages of digital integration product innovation. The results show that: In the initiating digital innovation stage, digital sensing capabilities reconfiguration is realized, which plays accelerated insight for potential digital innovation opportunities. In the developing digital innovation stage, digital learning capabilities reconfiguration is realized, which plays orchestrating enhancement for digital technology integration performance. In the implementing digital innovation stage, digital agility capabilities reconfiguration is realized, which plays remodeling support for value creation process transforming. The research results extend the literature on capacity reconfiguration and digital integration product innovation, and provide guidance for digital enterprises to accelerate the process of digital integration product innovation through capacity reconfiguration.
