The communication between the Communist Party of China (CPC) and the mass is the activities of the CPC to convey the principles and policies to the mass through various forms and channels, and to receive what the mass think, so as to realize the Party’s political goals. It is a vivid embodiment of the Marxist mass view and the Party’s mass line. In the past hundred years since its establishment, the CPC has completed the transformation from a revolutionary party to a ruling party, which determines that the communication between the Party and the mass has played different roles in different periods. It united the revolutionary forces in the Revolutionary Period (19211949), stabilized ideology in the Construction Period (19491979), reconciled diverse interests in the Reform and Openingup (19792012), and guided the way for democratic governance in the New Era (2012present). After the 18th National Congress of the CPC, with the changes of major social contradictions and social situations, to build a new type of communication between the Party and the mass in the new era, efforts should be made to go down to the grassroots level to do social research, to strengthen the interactive mechanism, to give full play to the advantages of new media communication, and to enhance the institutionalized communication channels.
