Abstract: The purpose of building consensus is to unify the ideological will of the entire Party and the country with the common goals and policies of the Party and the country, to look forward in unity, and to form a common ideological foundation for joint efforts. The great practice of building consensus over the past century of the Communist Party of China conforms to the fundamental position of seeking the interests of the people, reflects the theoretical consciousness of historical materialism, and solidifies the ruling foundation of governance that people want. In the new era and new journey, it is necessary to comprehensively analyze the new challenges faced by consensus building in the dimensions of subject, object, process, and environment, adhere to problem oriented and targeted exploration to consolidate the “backbone” of consensus building, identify the “common denominator” of consensus building, break through the “barrier wall” of consensus building, and build a “new battlefield” for consensus building, to continue to gather the fighting force for comprehensively realizing the great rejuvenation of the Chinese nation in enhancing the effectiveness of consensus building.
