【摘要】：利用投入产出分析方法,计算了我国2002~2007年出口贸易中隐含的SO2、COD和氨氮排放量,然后利用LMDI方法将影响上述排放量变化的因素分解为规模效应、结构效应和技术效应.结果显示:2002~2007年我国出口对国内SO2、COD和氨氮排放量的贡献都在20%以上,其中出口规模的扩大对于出口贸易中隐含SO2、COD和氨氮排放量增加起着重要的推动作用,而技术进步和出口结构变动的影响则随行业和时间的不同而呈现出显著差异性.分析我国出口贸易中隐含污染排放量较高的原因,主要来自于出口结构不合理,出口产品的环境效率低下,出口总量增速快.因此,本文对我国提出了几点政策建议,包括实施绿色贸易政策、绿化海关进出口产品目录、鼓励生态标志产品出口及采取进口替代政策.
[Abstract]:Using the input-output analysis method, the COD and NH3-N emissions implied in China's export trade from 2002 to 2007 are calculated, and then the factors affecting the above emission changes are decomposed into scale effects by using LMDI method. The results show that the contribution of China's export to domestic so _ 2 COD and NH _ 3-N emissions is more than 20% from 2002 to 2007, and the expansion of export scale plays an important role in promoting the increase of so _ 2 COD and NH _ 3-N emissions implied in export trade. The influence of technological progress and export structure change shows significant difference with industry and time. The analysis of the reasons for the higher implied pollution emissions in China's export trade mainly comes from the unreasonable export structure. The environmental efficiency of export products is low, and the total export volume is increasing rapidly. Therefore, this paper puts forward several policy suggestions to our country, including the implementation of green trade policy and the greening of the catalogue of import and export products of customs. To encourage the export of eco-label products and the adoption of import substitution policies.
