Abstract: The CPC’s construction of ideological leadership clearly demonstrates dialectical thinking. From the perspective of dialectical and unified relationship between the system and the elements, the CPC’s ideological leadership is the result of the synergy of five elements: subject ability, content vitality, method effectiveness, carrier synergy, and object cohesion. Focusing on the respective internal systems of the five elements, the CPC adopts the combination of hardness and flexibility about organizational constraints and ideological arming, the simultaneous development of political form and academic form, the promotion of debate criticism and solidarity dialogue, the complementarity of explicit evangelism and implicit indoctrination, and the resonance of material satisfaction and spiritual satisfaction. The CPC uses the viewpoints of connection, development, and unity of opposites to continuously forge the ability of the subject, temper the vitality of the content, improve the effectiveness of the method, and stimulate the combined force of the carrier and the re-creation of the cohesion of the object. Under the new historical mission, summarizing the CPC’s experience and wisdom in correctly handling these six pairs of dialectical unity is of great significance for the Party to observe the times, grasp the times, and lead the times with Marxist standpoints, viewpoints and methods.
