中国工业产品进出口贸易污染足迹对比分析

运用投入产出分析法建立了工业产品进出口污染足迹计量模型,计算了中国20个进出口工业部门6类污染物排放系数及排放量等多组数据.研究结果显示,国内环境污染加剧与工业产品大量出口密切相关.贸易顺差部门COD、SO2排放系数偏高,污染足迹净流入主要来自造纸印刷及文教用品制造业、非金属矿物制品业;污染足迹净流出主要来自化学工业; 2002年COD净流入31.00万t,SO2净流出48.87万t,其他污染物足迹大致平衡.

Pollution footprint contrastive analysis on industrial import and export in China

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.
