Through the analysis of a total of 263 public events on anti-corruption that produced great impact from 2011 to 2013，the study found that in 2013，the number of public incidents concerning anti-corruption is significantly higher than those in 2011 and 2012. In 2013，high incidence of public opinion events occurred in November. Guangdong and Beijing were the public opinion high-prevalence regions. Public opinion on anti-corruption spread rapidly，and the time interval between occurrence and exposure has significantly shortened，and more than half of the concerned public opinion incidents were exposed within one day. The majority of public opinion events were those that last less than a week or 1-2 weeks. Local government are the major subject of intervention；the proportion of events with intervention occurred before exposure was relatively high. Interview，announcement，and official website are the mostly used new release channels. Removing and giving criminal sanctions are the main ways of accountability. Nearly 50% of the public events had promoted the public policies.
