国际贸易对环境的影响:中国各省的二氧化硫(SO2)工业排放

为了更好地理解贸易对环境的影响,我们建立了一个四方程联立系统,其中SO2排放由规模、结构、技术这三个经济因素决定,并直接由贸易影响。然后我们利用中国29个省份1993—2001年期间工业SO2排放的面板数据来估计模型。我们的估计结果显示,出口和制造品进口在工业SO2排放的决定中起了完全相反的作用。结果不支持污染庇护地假说;出口企业所面对的市场竞争增强,是促进污染治理技术进步的积极因素。

Environmental Impacts of International Trade: The Case of Industrial Emission of Sulfur Dioxide (SO2) in Chinese Provinces

to get better understanding on tradeps impact on environment, we construct a four2equation simultaneous system, in which emission is determined by the three economic de2 terminants: scale, composition and technique effects, and directly affected by trade. the model is then estimated by 29 chinese provincesp panel data on industrial so2 emission ( 1993) 2001). our estimation results reveal opposite roles of export expansion and imports of manufactured goods in determining industrial so2 emission. the results do not support the / pollution haven0 hypothesis; the reinforced competition faced by exporters is a positive fac2 tor encouraging technology progress in pollution abatemen
