Air pollution has emerged as a persistent concern in Chinese society, affecting both individual health and economic development. This study employs behavioral finance principles and utilizes city-level panel data to investigate the relationship between air pollution and the demand for Chinese commercial health insurance, specifically examining the impact of annual PM2.5 concentration on premium income. Empirical analysis demonstrates a significant positive correlation between increasing PM2.5 levels and heightened demand for commercial health insurance. Moreover, the research reveals that a rise in the number of days with an AQI exceeding 150 in a given area and an increased societal emphasis on PM2.5 also contribute substantially to the demand for health insurance. These findings are robustly substantiated through comprehensive tests, underscoring the intricate interplay between air quality, health insurance, and broader economic implications in China.
