对国际贸易产生环境影响的定量研究正日益受到关注,特别是对隐含碳的研究。以中国2005年为例,对中国国际贸易隐含碳进行估算,应用对数平均D氏指数法(LMDI)对影响隐含碳净转移的因素进行分解分析。结果显示中国因生产排放碳量远大于其消费需要排放的碳量,从国外净转移到中国的隐含碳为395.66MtC;净转移隐含碳影响因素中强度效应(进出口商品完全碳排放系数差异)贡献率为60%,规模效应(进出额差异)贡献率为55%,结构效应(进出口结构差异)贡献率为-14%,此结果表明中国相比国外的高碳排放强度是造成目前碳转移额外增加的主要因素,分析结构效应发现中国主要净出口行业大部分不是高碳排放强度行业,而净进口行业却主要由高碳排放强度行业构成,特别是与碳排放密切相关的能源行业居净进口行业首位。
對國際貿易產生環境影響的定量研究正日益受到關註,特彆是對隱含碳的研究。以中國2005年為例,對中國國際貿易隱含碳進行估算,應用對數平均D氏指數法(LMDI)對影響隱含碳淨轉移的因素進行分解分析。結果顯示中國因生產排放碳量遠大于其消費需要排放的碳量,從國外淨轉移到中國的隱含碳為395.66MtC;淨轉移隱含碳影響因素中彊度效應(進齣口商品完全碳排放繫數差異)貢獻率為60%,規模效應(進齣額差異)貢獻率為55%,結構效應(進齣口結構差異)貢獻率為-14%,此結果錶明中國相比國外的高碳排放彊度是造成目前碳轉移額外增加的主要因素,分析結構效應髮現中國主要淨齣口行業大部分不是高碳排放彊度行業,而淨進口行業卻主要由高碳排放彊度行業構成,特彆是與碳排放密切相關的能源行業居淨進口行業首位。

Recently much attention has been given to quantifying the environmental impacts of international trade and there is an increasing concern over the impacts of carbon dioxide transfer embodied within international trade.In this paper,the balance of carbon emissions embodied in China's international trade for the year 2005 was calculated,and Logarithmic Mean Divisia Index(LMDI) was used in decomposition analysis of effect factors.The results show that production-based carbon emissions are much larger than consumption-based carbon emissions in China,and net transfer to China in terms of carbon emissions embodied within trade is 395.66 MtC.The contribution rate of intensity effect(the difference between total carbon emissions intensity of exports and that of imports) is 60%,the contribution rate of activity effect(trade surplus) is 55%,and the contribution rate of structure effect(the difference between structure of exports and that of imports) is-14%.According to results,high carbon emissions intensity and trade surplus of China are the major factors that affect carbon transfer to China,and intensity effect is more important than activity effect.It's worth noticing that structure effect is negative.Because most of China net exports belong to low carbon emissions intensity industries,however most of China net imports belong to high carbon emissions intensity industries,especially energy industries that have a close relationship with carbon emissions.
