Abstract: Getting policy across is important for earning support from the public and making them willing to follow, so, in the information age, it is very necessary to effectively display and organize policy information to ensure that the public understands policy contents accurately, timely, and comprehensively. This paper takes the interpretation information of prevention and control policies under public health emergencies as an example, and uses online controlled experiments to verify the effects of different readability and information frameworks on public understanding of policies. The results show that high readability and loss framework can significantly improve the public’s subjective and objective understanding, while the policy interpretation with narrative information can only significantly improve the public’s subjective understanding. In addition, the narrative framework interacts with readability and target framework respectively, and such interaction has a significant impact on improving the public’s subjective understanding. Further analysis reveals that combining high readability with narrative information or loss framing with narrative information is more effective in enhancing subjective understanding than using high readability or loss framing alone. The findings provide valuable insights and implications for public policy management departments and news media in formulating and disseminating policy interpretation information during public health emergencies.
