A Cross-Regional Study on the Public's Channel Preferences for Accessing Information

In this study, an online questionnaire was administered simultaneously in Beijing and Seoul to investigate the public's channel preferences for air quality index (AQI) information and risk perception of air pollution in order to comparatively analyze the public's information acquisition behaviors in different media environments. As people become more aware of the health risks of air pollution, the AQI has become routine information released when there is a need to warn of health hazards, and many countries are releasing it to the public through a variety of information channels to ensure that the public can perceive the risks and take appropriate measures in a timely manner. This study, through a comparative cross-regional analysis, found that public preferences for accessing AQI information varied across regions with differing media environments. In addition, the correlation between air pollution risk perceptions and information access behaviors varied across regions.
