The huge trade surplus of import and export trade of industrial products brings not only high profits, but also pollution costs as well. Based on the concept of water pollution footprints(WPFs), this study applies the input-output method and calculates pollutant-producing coefficients of 20 major industrial sectors in China and investigates the WPFs caused by the import and export trades of these industrial sectors. The research results show that WPF resulting from exports exceeds that of imports from 2011 to 2015 in China. The net inflow of pollution footprint is mainly from paper mills, printing and stationery manufacturing, and textile industry; whereas a great number of WPFs are transferred to other countries by these sectors,such as metal mining and dressing industry and oil and natural gas exploitation industry.展开更多

It translates production into biologically productive areas offering material flows to measure the utilized degree of nature by humankind. At present, China runs ecological deficits because footprints required for consumption are larger than available ones. In the paper, the ecological footprint model is applied to calculate the deficits by resource, environment and import-export accounting. It is clear that the deficits have caused enormous pressure to resource and environment, which would become bigger with more factors of resource and environment being accounted. In the primary production and energy trade, import footprint turned from deficit to surplus after 1996, which benefited the conservation of national resource. But compared with the huge depletion caused by resource and environment, they had small effects on deficits.展开更多
