每年大量的“中国制造”不断出口到发达国家,这些出口产品背后的隐含碳排放问题不容忽视。与已有文献主要利用美国、日本等国的数据间接获得中国碳排放率不同,本文通过直接计算中国2002、2005和2007年分产业部门的碳排放率,再以国内消费活动为标准利用单区域投入产出模型估算中国2000-2009年的隐含碳排放量,分析贸易碳排放净差不断增加的原因。实证结果表明,中国国内消费的碳排放总量将比国际公布的数据有所减少。中国在2000-2009年间保持贸易碳排放顺差,出口的高增长快速拉动了中国碳排放总量的增加。各国应当共同改善现行的碳排放量测算体制,同时中国也要鼓励低碳产品和技术贸易。
Every year, a large number of “Made in China” products are continuously exported to developed countries. The hidden carbon emissions behind these export products can not be ignored. Different from the existing literature that mainly uses the data of the United States, Japan and other countries to indirectly obtain the carbon emission rate in China, this paper directly calculates the carbon emission rate in China’s industrial sectors in 2002, 2005 and 2007, and then uses the domestic consumption activities as the standard. Input-output model estimates China’s implicit carbon emissions from 2000-2009 and analyzes the reasons for the increasing net trade carbon emissions. Empirical results show that China’s domestic consumption of carbon emissions will be less than the international data released. China maintained a trade surplus of carbon emissions from 2000-2009, and the high growth of exports rapidly boosted the total amount of carbon emissions in China. All countries should work together to improve the current system of measuring carbon emissions, while China also encourages low-carbon products and technology trade.
