以两次国共合作为例 ,阐明党派合作需要具备一定的恒定条件 :第一 ,两党为实现自己的总目标都面临着一个消除民族危机 ,实现民族复兴的共同的任务 ;第二 ,这个共同的任务单靠任何一党的力量都是难于单独完成的。第一次国共合作国共都难于单独完成的共同任务是反帝反封建 ,第二次国共合作国共都难于单独完成的共同任务是驱逐日本帝国主义出中国。历史事实证明 ,在这一恒定条件下完成的国共合作 ,对国共两党自身的发展壮大 ,对中国民族走向复兴和强盛 ,都取得了丰硕的成果。 Taking the cooperation between the KMT and the CPC as an example, this article states that certain conditions need to be met for the cooperation between parties. First, both parties must face a common task of eliminating ethnic crises and realizing national rejuvenation in order to achieve their overall goal. Second, The task of any party alone is difficult to accomplish alone. The common task that the first Kuomintang and the Kuomintang-Communist cooperation were both difficult to accomplish alone was anti-imperialism and anti-feudalism. The common task that the Kuomintang and the Kuomintang-Kuomintang-Communist cooperation were both able to accomplish alone was to expel the Japanese imperialists out of China. Historical facts show that the KMT-CPC cooperation completed under this constant condition has achieved fruitful results in the growth and development of both the Kuomintang and the Communist Party and in the rejuvenation and prosperity of the Chinese nation.
