Since the major proposition of "accelerating the construction of philosophy and social sciences with Chinese characteristics" was proposed, many achievements have been made in theoretical research and practical exploration, but there are also problems such as insufficient research continuity and stability, lack of clear problem orientation, and slow progress of the comprehensive formation of "Chinese characteristics".Xi Jinping Thought On Culture provides scientific theoretical guidance and fundamental action to follow for accelerating the construction of philosophy and social sciences with Chinese characteristics.The "soul vein" of Marxism and the "root vein" of China’ excellent traditional culture have respectively formed the ideological and civilization forms of accelerating the construction of philosophy and social sciences with Chinese characteristics.The "soul" of philosophy and social sciences with Chinese characteristics is the firm grasp and adherence to the socialist ideology with strong cohesion and leadership.The CPC has always attached importance to philosophical social sciences and ideology. Since the beginning of reform and opening up, the ideological field has faced risks and challenges.Since the 18th National Congress of the Communist Party of China, the ideological situation has undergone an overall and fundamental change.To speed up the construction of philosophy and social sciences with Chinese characteristics, it is necessary to accurately grasp the situation and orientation of ideological work, and on the basis of adhering to the "Chinese characteristics" of philosophical and social sciences, we should confidently and clearly criticize erroneous trends of thought such as "non-ideologization" and "ideological final conclusion", and use socialist ideology to lead philosophical and social sciences and consolidate socialist ideology with philosophical and social sciences.Xi Jinping Thought On Culture puts forward specific plans and arrangements for the construction of a socialist ideology with strong cohesion and leading force and the acceleration of the construction of philosophy and social sciences with Chinese characteristics, including improving the party’s innovative theoretical work system, fully implementing the responsibility system for ideological work, normalizing and institutionalizing education on ideals and beliefs, socialist core values, accelerating the construction of philosophy and social sciences with Chinese characteristics, creating an all-media mainstream communication pattern, improving the network-wide comprehensive governance system and other seven aspects, accelerating the construction of philosophy and social sciences with Chinese characteristics from the broad ideological level, adhering to the Marxist "soul vein" of philosophy and social sciences with Chinese characteristics, and enhancing the discourse power of philosophy and social sciences with Chinese characteristics that matches China’s comprehensive national strength and international status.
