One caveat with respect to Beijing life expectancy is that it only counts so-called Beijing residents, which excludes about 1/3 of the population in Beijing, i.e., migrant labour.
The conclusion to draw is that the air quality probably doesn't make that big an impact, but healthcare does. Beijing residents get free health care while migrant labour has to pay upfront.
