【摘要】：國際貿(mào)易的迅速發(fā)展是貿(mào)易隱含污染物排放轉(zhuǎn)移的主要驅(qū)動(dòng)因素,排放轉(zhuǎn)移的出現(xiàn)將排放責(zé)任的研究從生產(chǎn)者視角貢獻(xiàn)逐漸引向了消費(fèi)者視角貢獻(xiàn).合理的排放責(zé)任界定成為區(qū)域減排的重要參考.本研究利用多區(qū)域環(huán)境投入產(chǎn)出模型,以當(dāng)前社會(huì)廣泛關(guān)注的大氣污染物二氧化硫?yàn)檩d體,詳細(xì)分析了2007年全球各地區(qū)基于生產(chǎn)者視角、生產(chǎn)鏈末端視角、消費(fèi)者視角、考量區(qū)域減排努力的改進(jìn)的消費(fèi)者視角的大氣污染物排放貢獻(xiàn),并對各個(gè)視角下的區(qū)域排放進(jìn)行比較和分析.結(jié)果表明:西歐、北美、日澳新等地區(qū)生產(chǎn)者、生產(chǎn)鏈末端、消費(fèi)者視角的排放依次升高,而南亞、東亞地區(qū)的排放依次減小.大量的二氧化硫排放從西歐、北美隨著國際貿(mào)易供應(yīng)鏈轉(zhuǎn)移到東亞地區(qū).全球各地區(qū)二氧化硫排放強(qiáng)度的差異和全球貿(mào)易導(dǎo)致的生產(chǎn)格局的變化均為排放轉(zhuǎn)移的原因.本研究是貿(mào)易引致環(huán)境問題研究的重要補(bǔ)充,為區(qū)域乃至全球從貿(mào)易角度降低區(qū)域大氣污染問題提供了科學(xué)依據(jù).
[Abstract]:The rapid development of international trade is the main driving factor for the transfer of implicit pollutants in trade. The emergence of emission transfer has gradually led the study of emission responsibility from the producer perspective to the consumer perspective. Reasonable definition of emission liability becomes an important reference for regional emission reduction. Based on the multi-region environmental input-output model and the current social concern of sulfur dioxide as the carrier, this study analyzed in detail every region of the world in 2007 based on the producer perspective, the end of the production chain perspective, the consumer perspective. Considering the contribution of the consumer perspective to the regional emission reduction efforts, and comparing and analyzing the regional emissions from different perspectives. The results show that the emissions of producers in Western Europe, North America, Japan, Australia and New Zealand, the end of production chain and consumer perspective increase in turn, while those in South Asia and East Asia decrease in turn. A lot of sulfur dioxide emissions from Western Europe, North America as the international trade supply chain to East Asia. The difference of sulfur dioxide emission intensity in different regions of the world and the change of production pattern caused by global trade are the reasons for the emission transfer. This study is an important supplement to the study of trade-induced environmental problems and provides a scientific basis for regional and even global reduction of regional air pollution from the perspective of trade.
