摘要：

This paper investigates the impact of air pollution on people's interest in emigration. Using an online search index on "emigration" which is positively correlated with its search volume, we develop a city-by-day measurement of people's emigration sentiment. We find that searches on "emigration" will grow by approximately 2.3-4.8% the next day if today's air quality index (AQI) is increased by 100 points. In addition, such an effect is more pronounced when the AQI level is above 200, a sign of "heavily polluted" and "severely polluted" days. We also find that such effect differs by destination countries and by metropolitan areas.
