This study investigated information gathering behavior and risk perception of PM2.5 issues in China through a questionnaire survey, and aimed to discuss the relationship between them. As a result, it was found that citizens access more to damage, measures, and current status of PM2.5 issues. Regarding the relationship between information gathering behavior and risk perception, the existence of indirect effects via subjective knowledge was verified in addition to direct effects. This study also found that trust in information sources suppressed the direct effects, and evaluation of communication effects promoted the forepart of indirect effects while suppressing the latter half part. Comparing information gathering behavior with the results of the analysis regarding media coverage, there showed a discrepancy, which is the result of individual choices of information. And this study revealed citizens’ autonomy in the structure of risk perception because of above-mentioned indirect effects and moderating effects of trust in information sources and evaluation of communication effects.
