项目摘要

The international transfer policies of technologies to reduce carbon dioxide emissions should be considered as well as. usual technology transfer or diffusion. There are many infiltrate routes of technological diffusions and spillover. The route passes through the import products which embody foreign advanced technologies is important well as much as the routes pass through aids, foreign direct investments and purchasing royalties and licenses. After additional analysis of the possibilities of the carb on-leakage in import goods and distinguish high carbon intensity goods and the other, this paper shows quantifies impacts on carbon dioxide emissions by structural and these technological factors using panel data covering large sample of worldwide countries.The effects by the trade are measured. For example, correlations in carbon dioxide reduction and imports of transportation vehicles and equipments are measured in the developing country group. In the developed country group, there, are correlations in the information/telecommunication equipments and carbon dioxide reduction. Moreover, the import of industrial goods which can be manufactured with relatively low-technologies show meaningful correlation with the control of carbon dioxide emissions in all the income groups.This is similar to the argument of pioneer studies about the high-technological spillover from outside the country, but the technologies and know-how which influence for carbon dioxide emission control directly or indirectly are general and popular among the wide range of industries in developed countries.

还应考虑减少二氧化碳排放的国际技术转让政策。一般的技术转让或扩散。技术扩散和溢出的渗透途径有很多。这条途径既要通过援助、外国直接投资和购买特许权使用费等途径，也要通过体现外国先进技术的进口产品。本文在对进口商品中碳泄漏的可能性进行分析并区分高碳强度商品和其他商品后，利用覆盖全球大样本国家的面板数据，量化了结构性因素和技术性因素对二氧化碳排放的影响，并对贸易的影响进行了计量。例如，在发展中国家组中，二氧化碳减少量与运输车辆和设备进口量之间的相关性得到了衡量。在发达国家集团中，信息/电信设备与二氧化碳减少之间存在着相互关联。此外，可以用相对较低技术制造的工业品的进口与所有收入群体的二氧化碳排放控制都表现出有意义的相关性，这与先驱研究关于来自国外的高技术溢出的论点相似，但是技术和知识直接或间接影响二氧化碳排放控制的因素在发达国家的广泛行业中是普遍和流行的。
