- 貿易を経由した二酸化炭素排出量抑制技術の国際的拡散
International Technological Diffusions by the Trade and Possibility of Carbon Dioxide Control - Wataru FUJITA (Professor, Faculty of Economics, Nagasaki University)
- Abstract:
- The international transfer policies of technologies to reduct 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 carbon-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.
