Abstract: Using province-level newspapers‘ air pollution reports about prefecturelevel cities within the province from 2014 to 2017，this paper provides empirical evidences that media pressure can promote air qualityOur paper finds that the increase of air pollution reports significantly promotes air qualityMoreover，the magnitude of those effects are highly correlated with the type of newspaper (Party or Non-party newspaper) and the personal characteristics of the cities chief officials (ages and terms of offices)This suggests that air pollution reports mainly promote local governments’ effort on curbing air pollutionFurther study shows that the increase of environmental governance investment and the reduction of industrial pollution emission are effective ways for media pressure to promote the improvement of air qualityThis paper provides a new perspective for understanding the mechanism of public opinion supervision in the new era，and better playing roles of media supervision in environmental governance
