共产主义 (gòngchǎn zhǔyì) is the Chinese term for 'communism', a political and socioeconomic ideology rooted in Marxist theory. In the PRC context, it refers to the ultimate goal of the Chinese Communist Party and the highest stage of socialist development. You'll encounter this term in political discourse, historical texts, and official documents; it carries strong ideological weight and is distinct from the narrower English sense of 'communism' as a system of government.
