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.	Netnography is a qualitative research method that adapts the principles of cultural ethnography to the study of online communities and social media environments. Coined by Robert Kozinets in 1997 and systematised in his 2010 handbook, netnography treats digital spaces — forums, social networks, blogs, review sites — as naturally occurring field sites where communities gather, share meanings, and construct identities. The method combines unobtrusive observation of digital traces with active participation and, where appropriate, direct member interaction.
