Business-to-government(B2G)data sharing represents a critical intersection between digital government development and the cultivation of data factor markets.However, in practice, it is often constrained by firms' reluctance characterized as“unwillingness, inability, and uncertainty”to share data. Drawing on structuration theory of technology, this study develops a dynamic analytical framework of“situated motivations-sharing rules”and conducts a longitudinal single-case study of the“City Brain”initiative in Haidian District, to systematically uncover the implementation mechanism of B2G data sharing.The findings reveal that B2G data sharing evolves through a spiral mechanism of“situated motivations-sharing rules-value creation,”progressing across three stages:point-to-point connection, systematic sharing, and platform-based operation.During this process, governmental motivations shift from peer competition pressure to service empowerment and ecosystem building, while enterprise motivations evolve from risk avoidance to opportunity seeking and value realization.Sharing rules shape these motivations through two key pathways:organizational restructuring and technological enablement. Furthermore, the creation of governance, market, and social value serves as the core driving force that reinforces motivations and drives the iterative evolution of sharing rules.This study extends the analytical boundaries of structuration theory of technology to cross-sector data collaboration and provides both theoretical insights and practical implications for promoting government-enterprise data integration and fostering a sustainable data ecosystem.
