Impacts of Receiving International Industrial Transfer on China's Air Quality and Health Exceed Those of Export Trade.

ABSTRACT

Benefiting from international economic cooperation on income, technology diffusion, and employment, China also suffers its environmental and health impacts, from both international trade (IT), as is now widely understood, and international industrial transfer (IIT), which has been largely unrecognized. Here, we develop a comprehensive framework to estimate the impacts of exporting IT and receiving IIT. We find that China's emissions of CO2 and almost all air pollutants associated with IIT and IT together grew after 1997 but then declined after 2010, with the peak shares of national total emissions ranging 18-31% for different species. These sources further accounted for 3.8% of nationwide PM2.5 concentrations and 94,610 (76,000-112,040) premature deaths in 2012, and the values declined to 2.6% and 67,370 (52,390-81,810), respectively, for 2017. Separated, the contribution of IIT to those impacts was more than twice that of IT. Scenario analyses suggest that improving emission controls in its less-developed regions would effectively reduce the impact of economic globalization, but such a benefit could be largely offset by strengthened international economic cooperation. The outcomes provide a scientific basis for adjusting China's strategic roles in the international distribution of industrial production and its formulation of relevant environmental policies from a comprehensive perspective.
