Tóm tắt	Multiple case-based biographical research combines the cross-case replication logic of multiple case study design with the in-depth life-history orientation of biographical research. Each individual biography is treated as a bounded case, examined first on its own terms, and then analysed comparatively across cases to identify patterns, contrasts, and transferable insights about how lives are shaped by social, historical, and structural forces.	Multiple-case study design investigates two or more bounded real-world cases using the same research protocol, then compares findings across cases to identify patterns, contrasts, and explanatory insights that a single case could not produce. Developed primarily through Robert Yin's replication logic and Robert Stake's collective case tradition, the approach is particularly powerful when a researcher needs to determine whether a phenomenon occurs under varied conditions or to test an emerging theoretical explanation against rival contexts.
