概要	Multiple case-based netnography combines Kozinets's netnographic method — an ethnographic adaptation for online communities — with Yin's multiple case study logic. The researcher systematically collects and interprets naturalistic digital data from two or more distinct online communities or platforms, then conducts within-case analyses and a structured cross-case comparison to identify both shared patterns and context-specific differences. The design is especially powerful for understanding how cultural meanings, consumer practices, or social dynamics vary across different digital contexts.	Case study research is a qualitative research design that investigates a specific phenomenon, individual, group, organisation, or event in depth within its real-world context. Systematised by Robert K. Yin in 1984, it supports single-case and multiple-case designs and draws on multiple data sources — interviews, observation, documents, and artefacts — to build a rich, contextualised account of a bounded unit.
