So this study is undertaken to investigate the effects of Internet penetration on democratization based on the panel data of 125 countries gathered from 1993 to 2014. The authors apply machine-learning method (i.e., random forest) to effectively screen the variables that are more closely related to democracy. The results of different estimation models reveal an inverted U-shaped relationship between Internet penetration and democratization and also distinguish the impacts of the Internet on advanced and less advanced democracies. Then, we arrive at the conclusion that Internet penetration brings a late-starting advantage in the development of democracy for less advanced democracies. These conclusions are further confirmed by the robust test %K the Internet %K democracy %K inverse U-shaped curve %K panel data %K linear quantile mixed model %U https://journals.sagepub.com/doi/full/10.1177/0894439318767957
