摘要
This study examines why nuclear power in Taiwan remains persistently contested yet only partially stigmatised. Combining topic modelling with qualitative analysis of over 10,000 newspaper articles published between 2005 and 2021, we show that technological stigmatisation is continually reproduced through recurring framing contests rather than gradually resolved. Political turnovers, referendums, and catastrophic events such as the Fukushima nuclear accident generate event stigmas that interact with pre-existing core stigmas associated with nuclear technology. The repeated mobilisation of these event stigmas can crystallise into enduring symbolic imprints that shape collective memory and subsequent debates. Pro- and anti-nuclear actors draw on shared frames-particularly governance, well-being, and politics-but deploy them in incompatible and politicised ways, while distinct frames such as risk and democracy further intensify contestation. We contribute by theorising how the interaction of core and event stigmas sustains long-term framing contests and embeds energy debates within broader struggles over political legitimacy.
