中文摘要：

采用投入产出法的思想，通过构建数理模型，在中美两国2002年和2007年投入产出表的基础上测算了中美商品贸易的碳排放转移量。研究发现，由于中对美商品出口以劳动密集型与资源密集型部门为主、美对华商品出口以技术密集型与资本密集型部门为主。中国为美国的碳减排做出了很大贡献。认为应该从对商品和服务的消费角度来重新界定碳排放责任，为国际气候变化谈判提供更客观、可靠的数据；发达国家应向发展中国家提供技术和资金援助，发展中国家应进一步努力加强技术创新，共同减少碳排放。

英文摘要：

The paper adopts the input - output approach, by constructing mathematical model, to calculate the carbon emission transfer by Sino - US merchandise trade on the basis of the two countries input - output tables in 2002 and 2007. Study finds that China has made potential contribution to the carbon emission reduction of the United States. We also got other enlightening conclusion. Through analyzing the reasons of large carbon transfer occurred in Sino - US trade, finally we point out that accounting for the national CO2 and other greenhouse gases emissions should not be confined within national boundaries. It should refining emission responsibility from the angle of consumption of goods and services, providing more objective and reliable data for the international climate change negotiations. Developed countries should transfer technologies and funds to developing countries, developing countries should promoting technology innovation, we should make joint efforts to decrease the carbon emission.
