概要	Participatory multiple case study research integrates the structured logic of multiple case study design — examining two or more bounded cases to build analytic generalisations — with the collaborative ethics of participatory research, where community members or practitioners co-design the inquiry, co-collect data, and co-interpret findings. The approach combines Yin's replication logic across cases with the emancipatory and co-ownership principles that define participatory action research traditions.	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.
