Abstract: 【Purpose/significance】Based on the data sharing perspective, the hierarchical relationship among the components of the emergency logistics system is judged, the generation logic and countermeasures of the coordinated development of the system informa⁃ tization are analyzed, and the theoretical basis is provided for the management department to promote the coordinated development of the system informatization.【Method/process】Based on the data sharing perspective and the Delphi method, the binary relationship analysis of the system components is carried out and the adjacency matrix is calculated. Then the function relationship analysis is car⁃ ried out and the reachable matrix is calculated. The hierarchical relationship is determined by the interpretive structure model method. 【Result/conclusion】From the perspective of data sharing, the auxiliary surface layer includes "emergency plan data", "innovation and development data" and "information sharing data". The connection transition layer contains "disposal of post-recovery data". The im⁃ portant guidance layer includes "policy regulatory data". The core depth layer contains "command layout data" and "integration and coordination data".【Innovation/limitation】From the perspective of data sharing, the paper innovatively analyzes the generation logic and countermeasures for the coordinated development of emergency logistics system informatization, and builds an interpretive struc⁃ ture model to make the informatization research process more theoretical and objective. However, with the update of future cases, the determination of components and the division of levels will be updated accordingly. The future innovation of data sharing concept will also challenge the generation logic and countermeasure analysis of the coordinated development of system informatization.
