Is China's Pollution the Culprit for the Choking of South Korea? Evidence from the Asian Dust
利用亚洲沙尘这一外生气象现象，研究中国空气污染向韩国的溢出效应，发现中国污染加剧导致韩国呼吸和心血管疾病死亡率上升，对老人和儿童影响最大。
Abstract This paper studies the impact of air pollution spillover from China to South Korea. To isolate the effects of cross-border pollution spillover from that of locally generated pollution, we exploit within-South Korea and over-time variation in the incidence of Asian dust—a meteorological phenomenon exogenous to district–time cells in South Korea—together with temporal variations in China's air quality. We find that conditional on being exposed to Asian dust, increased pollution in China leads to increased mortality from respiratory and cardiovascular diseases in South Korean districts, with the most vulnerable being the elderly and children under five.
