概要	Comparative grounded theory applies the systematic inductive logic of grounded theory across two or more distinct groups, settings, or time points. Rather than generating a theory grounded in a single context, it builds theory that explains variation and similarity across contexts, producing conceptually richer and more transferable explanatory frameworks than single-site grounded theory studies.	Comparative ethnography is a qualitative research design that conducts in-depth ethnographic fieldwork across two or more sites, groups, communities, or cultural settings in order to generate systematic comparisons. Rather than describing a single community in isolation, it traces similarities, differences, and interconnections across cases, producing theoretically grounded insights that no single site could yield alone.
