The decade from 2010 to 2019 marked a significant turning point in China’s approach to environmental regulation and pollution. This review article examines recent trends in air and water quality, with a focus on the five years following the Chinese government’s announcement of its “war on pollution” in 2014. It also summarizes the emerging literature that has taken advantage of recent improvements in data availability and accuracy to understand the social, economic, and health impacts of environmental pollution in China.

We provide an empirical review of the Chinese capital market, focusing on the basic return and risk characteristics of its major asset classes, as well as a comparison to the US market. All major asset classes in China have significant higher volatilities than their counterparts in the US market, but they do not always yield larger returns. Small-company stocks, short-, medium-, and long-term treasury bonds outperform their US counterparts, while large stocks underperform and long-term enterprise bonds yield similar returns.
We exploit the staggered rollout of China’s drug price zero-markup policy (ZMP) to study physician-induced demand in healthcare. Our results show that the drug expenses in the treatment hospitals dropped by 63 log points (47 percent) compared with those of the control group; however, the expenses for non-drug services were 28 log points (32 percent) higher in the treatment group than in the control group. Our results provide robust evidence for physician-induced demand.
In China, migrant children are at a disadvantaged and sometimes cannot enroll in public schools in migration destinations due to policy restrictions. Some migrant workers then have to leave their children behind in their hometowns, which causes the left-behind children problem. This study finds that if the enrollment restriction on migrant children is relaxed, migration of parents and children will increase, and the average human capital in the society will also increase. Low-skill families from small cities benefit most.
