雾霾影响下的外出就餐消费

Impacts of Haze Pollution on Dining Out

本文以2013年和2015年的中国家庭金融调查数据作为微观数据来源,并匹配相关的城市数据,构建混合截面数据,实证分析了空气污染对外出就餐消费的影响。结果显示:空气污染显著降低了家庭的外出就餐消费支出,且居家就餐并不会形成对外出就餐的替代。平均来看,年均PM2.5浓度提高1%,家庭年外出就餐消费支出减少0.546%。在异质性分析中,空气污染对外出就餐消费的影响因样本组的不同而不同,空气污染对城市流动人口和受教育程度在大专及以上人群的外出就餐消费的抑制效应要高于城市本地人口和受教育程度为高中及以下人群。在机制分析中,空气污染通过减少外出就餐频率、增加医疗保健支出以减少外出就餐消费支出。本文的研究为改善空气质量以促进外出就餐消费提供了经验证据。

This paper uses 2013 and 2015 CHFS data as microdata,matched with urban data,to construct mixed cross-sectional data and empirically examines the effect of air pollution on dining out.The results indicate that air pollution has a significant negative effect on household annual dining out expenditure,and dining at home does not replace dining out.Specifically,a 1%increase in the annual average PM2.5 concentration is associated with a 0.546%decrease in household annual dining out expenditure.The results of heterogeneity analysis show that the negative effect of air pollution on dining out expenditure is more pronounced among the migration people and the population with college and above education,compared to the urban local residents and the population with high school and below education.The mechanism tests show that the negative effect of air pollution on household annual dining out expenditure is due to a reduction in the frequency of dining out and an increase in residents'health care consumption.The study provides empirical evidence for improving air quality to promote dining out.
