Abstract: Based on the data-driven theoretical perspective，this paper selects Haier as the case study object，adopts the dynamic logic framework of "data-driven-dynamic capability improvement-digital business model innovation"，and systematically explains the process mechanism of digital business model innovation by using grounded theory. It is found that the realization of digital business model innovation depends on the full utilization of organizational data resources，and data-driven is an important motivation for the realization of digital business model innovation，which includes three key links: "demand source establishment-scene chain linkage-network sharing interaction"; Data-driven plays an important role in the exertion and promotion of organizational dynamic capabilities，and dynamic capabilities supplement the intermediate mechanism of enterprise data-driven as the antecedent to realize the optimization of enterprise digital business model components; From the perspective of overall generation，the innovation of digital business model is realized based on the three-dimensional dynamic process of "value proposition calibration-scene experience optimization-value network expansion". The research provides theoretical and practical guidance for the innovation of business model in the digital economy era.
