Abstract:

The study on relationship between trade and CO2 emission will make the origin sources of CO2 emission more distinct and will be helpful to policy making of CO2 emissions reduction and replying the global climate change problem. By mean of the framework of non-competitive input-output models, this article sets up a relationship model for CO2 emissions of anthrop industrial activities between two regions by the way of decomposing the economy activities into exporting, importing, consumption and investment combined with a sensitivity analysis. Then the authors calculate the CO2 emissions induced by consumption, investment, export and import in 2007 in China respectively. A sensitivity analysis is also carried out. The conclusion is that the augment of export and the improper of export structure is the main reason for the rapid increase of CO2 emission gross in China. Especially, in the year of 2007, the CO2 emission induced by net export accounting for 29.1% of Chinese gross CO2 emissions. And the huge investment in domestic building, a great deal export and investment in mahinery, transport and electronics equipment, the domestic consumption of service, electric and heat power, eating, the large amount export of metal and chemical products are the main origin sources and highest emission elasticity economic activities in the perspective of complete consumption. So it is an efficient way as well as a key task to change the export structure, expedite the international transfer of high energy-using industries, and promote the industrial technology and add-value of export products. At the same time, advocating civil emission reduction, and making great effort to build a conservationminded society, especially cutting down the waste from building industries and service energy uses are also important measures for the energy saving and emission reduction in China.
