The core of socialist ideology is Marxist discourse power, which refers to Marxism’s dominance in ideological education and dissemination as well as its dominant position throughout the entire social ideological system. Big data (BD) has altered how people think, captured recent advancements in the process of thinking development, enriched and advanced thinking science, and improved how people think in relation to the times. This paper examines the BD era’s discourse power construction of Marxist ideology. The percentage of respondents who answered “several times a day” when asked if they listen to, watch, or read political news on a daily basis increased from 7.2 percent in 2018 to 17.5 percent in 2021. The percentage of “once a day” and “several times a week” responses also increased, but the response “once or twice a week” did not. Understanding the latest developments and ideas in human thinking in the age of BD can help us think more broadly and creatively, and it can also give us the theoretical groundwork and thinking power to advance the use and development of BD.
