Public sector data opening has become an important development task in China, but whether it really promotes the interaction between the government and the public remains to be verified.Therefore, this paper adopts survey experimental method to explore the influence of different ways of government presenting data (with and without visualization, with and without social comparison) on public participation and government trust. The results show that the government adoptsvisualization and social comparison to display data respectively, which can promote public participation in government activities and further enhance public trust in the government, but the inclusion of social comparative data does not moderate the relationship between visualized data and public participation.Therefore, the study suggests that the government can present data by visualizing or adding social comparison respectively, to arouse public attention and interest in government data, and then strengthen public participation and trust. Overall, the article uses survey experiment research methods to analyze micro-level government-public interaction and explore the causal mechanisms between data presentation, public participation, and government trust, which not only enriches micro-levelresearch on government-public interaction but also expands the application of survey experiments in the field of behavioral public management in China.
