Abstract: Self-confidence of the Socialist System with Chinese Characteristics is a kind of solid faith and firm belief on the practice and theory of Socialism with Chinese Characteristics， and it is also a kind of conscious identity， affirmation and support on the efficacy and advantage of Socialism with Chinese Characteristics. To strengthen system self-confidence， we must strengthen the understanding and grasp of the internal law of self-confidence of the socialist system with Chinese Characteristics. The dialectical unity law that reveals how the system theory and system practice develop is the basic premise to grasp system self-confidence. The important standards that always regard the participation and support of the people as a means of judging the superiority of the system is the value thread to consolidate system self-confidence. Constantly summarizing， testing and deepening the system's scientific truth is the power support to promote system self-confidence. The integration of the perceptual cognition of system goals and rational identification of system concepts is the key link to strengthen system self-confidence. Pursuing the system's optimal effect with most powerful execution is the core guarantee to realize system self-confidence.
