贸易开放与碳排放转移:来自中国对外贸易的证据

Trade Openness and Carbon Emission Transfer:Evidence from China's Foreign Trade

库兹涅兹曲线显示,1960~2010年中国经济增长与碳排放存在"N"形曲线关系,贸易开放对中国人均碳排放存在正向影响,贸易开放程度每提高1%,人均碳排放量增加0.3%。投入产出模型揭示,2007年中国对外贸易隐含碳排放转移27.1亿吨,占当年碳排放总量的39.76%。其中通信设备、计算机及其他电子设备制造业出口碳排放最高,占出口碳排放21.2%。依次为化学工业(10.7%)、电气机械及器材制造业(9.8%)、金属冶炼及压延加工业(8.68%)、通用、专用设备制造业(7.53%)。

Environmental Kuznets Curve shows,a cubic relationship between GDP and CO_2 emissions is found to fit the data most appropriately for the period 1960~2010in China.Trade openness has positive influence on per capita carbon emissions in China.Trade openness degree increase1%,per capita carbon emission increases correspondingly by0.3%.Input-output model shows that in 2007 China exported embodied carbon emissions by2.71 billion tons,accounting for 39.76% of China's total carbon emissions.Including communication equipment,computers and other electronic equipment manufacturing exports most carbon emissions,accounted for 21.2% of total exports of carbon emissions.Followed by chemical industry(10.7%),electrical machinery and equipment manufacturing industry(9.8%),metal smelting and rolling processing industry(8.68%),universal and special equipment manufacturing industry(7.53%).
