過去研究已指出選舉輸家和贏家在民主滿意度和政治支持上具有顯著的差異，然而卻鮮少有研究檢視選舉輸家和贏家在情感極化的程度上是否有顯著的不同。本研究認為在選舉競爭激烈的情況下，選舉輸家對於勝選者缺乏信心，不信任勝選者會回應其需求，加深其與勝選陣營之間的鴻溝，進而具有較高的情感極化程度。另一方面，選舉贏家則因為處於勝選、掌握政治權力的一方，對於敵對陣營可能較具有包容力，因此會具有較低的情感極化程度。此外，本研究進一步提出選舉輸家/贏家與情感極化之間的關係會受到治效能感的調節作用而產生異質性的影..

Previous research has pointed out significant differences between electoral losers and winners in terms of democratic satisfaction and political support.

Party alternation is an important condition for the development of modern democracy. Although the Japanese democracy after World War II proceeded from the enforcement of the new constitution, LDP dominated the Japanese politics since 1955. The party alternation thinking in Japan was limited by the situations of domestic and international environment such as politics, economics, society and parties. The end of the Cold War liberated the party alternation thinking in Japan, and led to the formation and development of DPJ. This ..
