Abstract：Air pollution has become an important element affecting the urban life quality in China, which not only directly affects health and life expectancy, but also affects working efficiency, mood, outdoor activity frequency, trip for consumption and social interaction, further reducing the economic vitality and social vitality of cities. Taking Beijing as a case, this paper works on how air pollution affects residents' dining out frequency and satisfaction based on the reviews from dianping.com and the PM2.5 concentration data released by the Ministry of Environmental Protection. The results show that by controlling other factors, air pollution can reduce dining-out frequency and satisfaction of residents. The quantitative results present the willingness intensity of urban residents to circumvent air pollution and contribute to an accurate assessment of to which degree socio-economic activities and resident life quality will be affected by air pollution increase.
