Climate Change, Health and Migration in Urban China

In this paper, I empirically investigate the effect of climate change on health and migration in China. Using urban survey data sets from different Chinese cities, I find that an increase in female morbidity is associated with current high temperature change, especially for the symptom of frailty; past hot weather is related to the exacerbation of health problems in women, and the effect on females is larger than that on males who migrate from rural areas to cities; past temperature change is also correlated with a higher probability of chronic symptoms for females. I also find that migration preference from a rural area to a city is correlated with avoiding exposure to hot weather shocks, which shows a regressive tendency. Finally, the migration preferences of male residents who migrate from one city to another city are not associated with the effects of past low temperature changes on health.
