Abstract Governments information release by the new media has become an important way to bring innovation in the field of governance and social services. Evaluating the effectiveness of information release by government microblogging helps improve the government's ability to deal with public opinion in the big data environment. From the perspective of the new public management theory, this study proposes a method to evaluate the effectiveness of information release by government microblogging based on the “Cognition-Emotion-Behavior” theory and data envelopment analysis model. Microblog entries related to the southern flood in 2020 were collected. Thereafter, based on persuasion theory, we identified the influencing factors of the information release effectiveness of government microblogging. Seven regression models were established. The SHapley Additive exPlanations (SHAP) technique was used to analyze the importance of features and interaction of the LGBMRegressor model, which offers optimal comprehensive performance. The influencing mechanism of the effectiveness of government microblog information release is revealed. The obtained results provide numerous suggestions on enhancing the effectiveness of government microblog information release during public emergencies, which is of great significance in improving the ability of government microblogging to deal with public opinion in the digital era.
