Forecasting the use of force: a word embedding analysis of China’s rhetoric and military escalations

Abstract Is an autocracy’s official rhetoric a reliable proxy for forecasting military escalation? While the conventional hands-tying mechanism argues that official rhetoric binds leaders to stated positions and limits their ability to back down, recent scholarship on bluster suggests that autocracies may employ hawkish rhetoric to justify de-escalation ex-post. This study evaluates these competing perspectives by analyzing China’s official rhetoric and military behavior in the Taiwan Strait from 2016 to 2022. Employing a word-embedding approach, I construct an original Chinese-language lexicon capturing implicit threats from over two million state-media articles. I show that increases in China’s implicit threats toward Taiwan are associated with a higher likelihood of military escalation, implying that official rhetoric conveys predictive information rather than mere cheap talk.
