Abstract: Starting from the fundamental principles of materialism,Marx's system analysis method is to grasp the nature of system by illustrating the dialectical relations between system and man,and system and society.Marxism has always stressed on starting from reality on the issue of man,which calls for concern on human existence in reality,while system is the realization of human existence and development.In analyzing and disclosing the evil of capitalism,Marx showed a great humanistic concern on human existence,development,future,and fate.The starting point of Marx's system analysis was the solution to reality and necessity,and the goal was to find a way for man to realize all-round development.

Key words: Marx, system analysis method, human all-round development, way of realization
