抗战时期汪精卫叛国投敌的原因有三 :特定历史条件下与蒋介石的权力争夺和政见分歧是内因 ,日本的“扶汪弃蒋”诱降政策是外因 ,汪精卫特殊个性和其阶级基础是根本原因。三个原因的合力致使汪精卫竟敢冒天下之大不韪而公开逃叛。 There are three reasons for Wang Ching-wei to defeat the country during the war of resistance against Japan: the power struggle with Chiang Kai-shek and the political disagreement under specific historical conditions are the internal causes. Japan’s temptation to abandon Chiang Kai-shek policy is the external cause. Wang Ching-wei’s special personality and his class basis are the fundamental reasons. The combination of the three causes Wang Ching-wei dare to take the world over the big and openly betrayed.
