不同城市化进程的碳排放特征差异比较——基于LMDI分解

在全球气候变暖的背景下,碳排放问题备受中国乃至整个世界的关注,同时,中国正处于快速工业化和城市化的阶段,区域之间由于所处的城市化阶段存在差异而导致碳排放表现出不同的特征.通过聚类分析的方法,以城市化综合指标为基础,把全国不包括台湾、香港、澳门地区在内的31个省、市、自治区分成不同城市化进程的三类,进而运用LMDI方法对三大区域碳排放的影响因素进行分解,以期比较三大区域因城市化进程不同而存在的碳排放特征差异.分解结果表明,城市化进程最快的区域碳排放增长最慢,而处于城市化进程中问阶段的区域碳排放增长最快;能源强度对不同城市化进程的区域碳排放的抑制效果存在明显差异——对城市化进程最快的区域抑制作用最明显,对处于城市化中间阶段的区域最不明显.

The Difference Comparison of Carbon Emission Characteristics in Different Urbanization Process——Based on LMDI

Under the background of global warming, carbon emission has become the hot topic of China and the whole world. Meanwhile, China is in the stage of .rapid industrialization and urbanization, and regions show different characteristics on carbon emission because of different urbanization process. This article divides 31 provinces into 3 groups with different urbanization process by the means of clustering analysis, based on urbanization aggregative indicator. Then decomposing the carbon emission of the three regions by LMDI in order to compare the differences among them. The results show that the carbon emission increase slowest in the fastest urbanization process region, while fastest in the middle stage region; energy intensity has different inhibition effect on carbon emission of regions with different urbanization process - - greatest in the fastest urbanization region but least in the middle stage region.
