This paper used contingent valuation method （CVM） to investigate the cognitive status, behaviors selection and willingness to pay of Beijing residents for reducing PM2.5 health risks. The results demonstrated： ①82.5% of the residents deemed that air pollution in Beijing was serious, 52.4% of the residents realized that haze days were caused by PM2.5 and concerned for themselves and their family＇s health, 92% of the residents deemed that the government should take more responsibiliies to reduce health risks caused by PM2.5.②It is found that among the activities to reduce risk, the activities that were welcomed are those which can save the cost of living, be good to lifestyle and conform to daily habits; while the activities that would reduce the living comfort and increase the cost of living got less support. ③Under the scenario of reducing 30% concentration of PM2.5, the willingness to pay by the residents is 22.78 RMB/month; while under the scenario of reducing 60% concentration of PM2.5, the willingness to pay by the residents is 39.82 RMB/month. Besides, factors such as resident personal characteristic, economic condition, resident location, transportation, cognitive level and risk communication etc.. All exert significant influences on the willingness to pay to reduce PM2.5 health risk.
