Characteristics of Carbon Emission in China and Analysis on Its Cause

Abstract

From the history of human economic development, it is known that there is a close relationship between economic development and environment quality. Thus, in this study a factor decomposition model of carbon emission in China is built and the contributions that economic scale, industrial structure, and carbon emission intensity make to carbon emission quantitatively from 1990 to 2005 are analyzed, in other words—scale effect, structural effect, and technical effect—using the decomposition method of average distribution cushion which is based on the environmental Kuznets curves model is studied. The result suggests that the average of the effect changes of carbon emission in China is 19.55%, the effects brought by economic scale, industrial structure, and carbon emission intensity are 15.76%, −0.86%, and 4.65%, respectively. In general, the relation between carbon emission and China's economy was more like an “N” curve; Economy scale is a primary drive factor and has incremental effect to carbon emission. Since otherness of different industry is getting bigger, the industrial restructure has certain decremental effect to carbon emission, but the restrictive function is not obvious, the industrial structure still need to be further optimized; the technical effect is positive and its volatility is large. From the perspective of reducing carbon emission, the current technology has not played to its advantages. This study will promote the understanding of the theory about the relationship between carbon emission and economy development and provide reference value by all means to the adjustment of industrial development.
