| 摘要空气污染已经成为影响中国城市居民生活质量的重要不利因素。它不仅直接影响人们的健康和寿命, 还会对人们的工作效率、情绪、户外活动频率、消费出行和社会互动意愿等多方面形成负面影响, 进一步降低城市的经济和社会活力。该文以北京为例, 利用大众点评网线上点评数据与环保部发布的PM2.5浓度数据, 研究空气污染是否会影响人们外出就餐频率, 以及空气污染对情绪的影响是否会影响人们对相同质量餐馆的评价。研究结果表明: 在控制其他影响因素的基础上, 空气污染会降低居民的外出就餐频率和满意度。该文的定量研究结果给出了城市居民规避空气污染的意愿强度, 有助于准确评估污染对于社会经济活动和居民生活质量的影响程度。 | ||||||

| 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. | ||||||
