Abstract:The pollution footprint model was built on the basis of the input-output analysis to measure the discharge coefficient and amount of 6 pollutants in 20 Chinese industrial sectors. The domestic worsening environmental problem was closed linked with industrial exports, the industrial sectors with trade surplus COD and SO2 discharge coefficient was obviously higher than those with trade deficit. The inflow of pollution footprints came mainly from the net export of paper and non-metallic mineral industry, and the outflow of pollution footprints came mainly from the net import of the chemical industry. The net inflow of COD was 310000 tons and the net outflow of SO2 was 488700 tons, the pollution footprints of other pollutants were approximately balanced in 2002.
