In the context of a diverse media landscape grappling with an increasingly stringent political climate, this study asks whether the Chinese government’s media-control policies shape public opinion. Drawing on online survey data collected between 2014 and 2018 and using regression models and inverse probability weighting, I find that in 2017, as Xi Jinping began his second term as general secretary, there was a noticeable conservative shift in the political attitudes of the Chinese public. While foreign media might have reduced support for the Chinese Communist Party’s stance and ideology among those with less exposure to the party-state media, state propaganda did shift public attitudes, offsetting the impact of foreign media. These findings underscore the Party’s effectiveness in using media censorship and propaganda to consolidate its legitimacy in the ideological sphere.
