Contrastive analyses of the influence factors of interprovincial carbon emission induced by industry energy in China

Abstract

As a major contributor of carbon emission in the world, China should focus on the balance between the universality of development and regional heterogeneity of carbon discharge during the transformation toward low-carbon economy. To reveal the differences among interprovincial industry energy's carbon emissions, some relevant data of carbon emissions in 29 provinces and municipalities during the period of 1996-2012 are selected in this study. Based on the Logarithmic Mean Divisia index decomposition model and hierarchical clustering method, the 29 provinces were clustered in turn by four time intervals according to some indicators, including economic intensity, energy intensity, industry structure, energy structure, demographic effect, and carbon density influence. Research results show that during 1996-2000, economic intensity has a strong positive driving effect on carbon emissions in such eastern provinces as Shanghai, Zhejiang, and Jiangsu, and other seven inland provinces, such as Hunan and Hubei. Demographic effects have strong pulling effects on carbon emissions in municipalities and eastern coastal provinces, and they also exert strong negative effects on carbon emissions in Anhui, Guangxi, Guizhou, and Sichuan in the first three time intervals. During the four periods, highly energy-efficient provinces are Jiangsu, Guangdong, Sichuan, Shandong, Hubei, etc., whose carbon emissions are significantly inhibited by their energy intensity, whereas inefficient provinces are concentrated in western regions, like Guangxi, Hainan, Gansu, Qinghai, Ningxia, Xinjiang, etc.

Research Themes, Evolution Trends, and Future Challenges in China’s Carbon Emission Studies

“…Moreover, the impact of the same influencing factors on carbon emissions varies across different regions. For instance, Chinese scholars such as Niu [113], Zhou [114], and Zhang [115] separately investigated the influence of economic levels, population, and industrial structure on carbon emissions in different regions.…”

The Analysis of Carbon Emission’s Characteristics and Dynamic Evolution Based on the Strategy of Unbalanced Regional Economic Development in China

“…However, on considering many historical, geographical and cultural factors, Chinese provinces are geographically established. Some scholars classified Chinese provinces into several groups with the methods of k-means clustering, system clustering, met frontier DEA clustering, and fuzzy PSO clustering [38][39][40][41]. In order to demonstrate the necessity of zoning, more researchers began to take economic zones, national development strategies and regional development strategies as the fundamental basis for their zoning plans.…”

Examining the Driving Factors of the Direct Carbon Emissions of Households in the Ebinur Lake Basin Using the Extended STIRPAT Model

“…Gunther et al [16] quantified the carbon footprint of cotton production in Xinjiang, and analyzed the spatial and temporal differences and driving factors of agricultural carbon emissions in Xinjiang. Zhou et al [17] calculated the carbon emissions from thermal power industry in Xinjiang. Cui et al [18] studied the spatial pattern of industrial carbon emissions in prefecture-level cities in Xinjiang.…”
