Model Research of CO₂ Emissions Characteristics of China’s Industrial Sectors

Abstract:

This paper calculated CO₂ emissions of China’s three industries, industry, construction, light industry, heavy industry and industrial trades on the basis of the statistical data from 1990 to 2010.The factors, influencing the CO₂ emissions change of industrial sectors, were decomposed into economy factor, structure factor, efficiency factor and emission factor through the complete decomposition model. And then the effect of these factors over years was quantitatively analyzed. The analysis results showed that, firstly, China’s industrial sectors’ CO₂ emissions were mainly from the secondary industry whose emissions were from industry mostly. And further, the industry’s CO₂ emissions were mostly from heavy industry, mainly the six major trades. Secondly, economy factor contributed to the CO₂ emissions increase. Structure factor and emission factor acted insignificant roles in CO₂ emissions reduction. And China’s CO₂ emissions reduction relied mainly on efficiency factor during the inspection period. And finally, changing the mode of economic growth is an effective way to slow down the rapid growth of China’s CO₂ emissions. Both structure factor and efficiency factor have fine effect to CO₂ emissions reduction, and the structure factor gets even more obvious.
