Factor Decomposition of Carbon Productivity Chang in China's Main Industries: Based on the Laspeyres Decomposition Method

Abstract

Carbon productivity can integrate two goals of low-carbon economy, in the framework of low-carbon development, improving the carbon productivity has become the key strategy responses to the global extremely weather. This paper studies the level of low carbon development of China's eight major industries and uses Laspeyres index decomposition method to analysis the characteristics of China's carbon productivity change and the sources of industry structure from 2003 to 2011. Research results reveal that the structure factors hindered the growth of China's carbon productivity, and carbon productivity growth mainly comes from the industry production efficiency; agriculture and manufacturing have inhibitory effect on carbon productivity in the structure factors, while in the efficiency factors they have strong promoting impaction; other services in the structure factors play stronger roles in promoting carbon productivity growth.
