日本民主的穩定可能部分源於公民對權威的支持，而非對民主原則的認同。本文運用亞洲民主動態調查的資料，檢驗了威權價值對民主正當性與體制支持產生的影響，並分析其與政黨認同之間的關聯。結果顯示威權價值愈高的日本民眾，愈不傾向認同民主為最佳政體，卻愈支持現行政治體制。此外，威權價值亦與非執政陣營支持者轉向認同執政陣營具有穩定關聯，本文將此現象概念化為「權威追求式政黨認同」。當體制支持主要建立於對權威與執政者的支持，而非對民主程序與權力制衡的信念時，可能高估了民主體制的實際韌性。

Japan’s democratic stability may rest partly on citizens who support authority rather than democratic constraint. Using the Japanese Asian Barometer Survey, this article asks whether authoritarian values separate democratic legitimacy from regime support and whether they are associated with partisan alignment toward incumbent power. The results show a consistent split: citizens with stronger authoritarian values are less likely to endorse democracy as always preferable but more likely to support the existing political regime. Per-wave authority-seeking models further associate authoritarian values with alignment toward the governing side among non-winner voters. I conceptualize this pattern as authority-seeking partisanship. Aggregate regime support may therefore overstate democratic resilience when it is grounded in authority and incumbency rather than in principled commitment to democratic procedures and constraints.
