Will developed countries turn China into a haven for "dirty" industries through international trade by specializing in producing and exporting "clean" products and importing pollution-intensive products from China? How does international trade affect Chinese industries' CO2 emissions? This paper presents an empirical test of these hypotheses using statistical techniques such as the environmental input-output model and net exports as a proportion of consumption(NETXC) based on the trade data of 20 industries in China,and G7 and OECD developed countries.In this study,we draw three conclusions:(1) The proportion of domestically produced CO2 emissions in CO2 emissions embodied in products exported from China has been declining;(2) Industries migrated or displaced from developed countries into China include both "dirty" and "clean" industries;(3) International trade can help industries reduce CO2 emissions in aggregate and per unit of output.China has not become a haven for developed countries' "dirty" industries as a result of international trade.
