The contemporary world socialist movement has changed significantly and new transformation has come true. The mode of world socialist movement has been changed from one world centered leader，one sole revolutionary way，and constructing one unified socialism mode，to different communist parties’ independent leading，following the revolutionary development paths suitable to their national conditions and constructing the socialism with their countries’ distinctive features. The transformation of the contemporary world socialist movement is chiefly characterized by the following aspects：it has transformed from the movement outside the capitalist system，to the one inside the capitalist system；it has changed from the way of proletarian revolution to overthrowing capitalism，to the way of peacefully and democratically revolutionary transformation of capitalism；it has changed from the participants in the movement composed of the advanced sectors of society for the most people’s benefits，to the majority of the participants for most people’s benefits.
