Ideological party building and system governance are the core of the party governance of the Chinese Communist Party. Most of the existing literature focuses on the integrated analysis of the two forces at the same time and in the same direction at the level of "what should be". This article takes the standardized construction of a party branch promoted by a state-owned enterprise as a case, and focuses on the "real" level of ideological party building and system governance at the same time and force in the same direction. This paper develops a measuring scale for the effect of ideological party building and system governance, and proposes the combination of ideological party building and system governance based on the interaction model of individual cognition-emotion-behavior of party members. Studies have shown that party members have a high degree of recognition for ideological party building and system governance based on the standardization of basic-level party organizations in state-owned enterprises. Different gender, age, party age, and whether or not they hold an internal party position have a helpful influence on the effect evaluation. Holding an administrative position does not affect the evaluation of party members. The study uses correlation analysis methods to verify that ideological party building and system governance are synchronized and exerted in the same direction.
