Greasing the wheels of policy reversal: Discursive engineering and public opinion management during the relaxation of China's family planning policy

How do autocratic regimes use political propaganda to facilitate policy reversals of major significance? In this article, we demonstrate how the authoritarian regime in China dynamically uses propaganda to accomplish rapid discursive shifts in the context of major policy changes. Using a structural topic model for unsupervised machine learning to analyze extensive propaganda materials, we explore how the Chinese Communist Party facilitated the reversal of its One-Child Policy in 2015 by deploying a systematic, precise, multi-dimensional, and multi-layered discursive engineering project. Our findings demonstrate that instead of a monolithic and rigid operation, China's state propaganda is a strategic and flexible discursive engineering project tailored to contingent factors, such as the nature of the policy being advocated, the level of the propaganda venue, and the needs, mentality, and tastes of carefully targeted audiences. This coordinated maneuver of state narrative is key for the effective and smooth policy reversal of major significance.
