Abstract
With continuous industrialization and urbanization, cities have become the dominator of energy consumption, to which industry is making leading contribution among all sectors. Given the insufficiency in comparative study on the drivers of energy use across cities at multisector level, this study selected seven representative cities in China to quantify and analyze the contributions of factors to changes in final energy use (FEU) in industrial aggregate and sectoral levels by using Logarithmic Mean Divisia Index method. Disparities in the drivers of industrial FEU across cities were explicitly revealed within two stages (2005–2010 and 2010–2015). Some key findings are presented as follows. Alongside the increase in industrial output of seven cities within two stages, the variation trends in industrial FEU are different. Industrial output effect (contribution rate 16.7% ~ 184.0%) and energy intensity effect (contribution rate −8.6% ~ −76.5%) contributed to the increase in aggregate FEU positively and negatively, respectively. Beijing had the largest contribution share of industrial structure effect (−24.4% and −12.8%), followed by Shenyang and Xi’an. Contributions of energy intensity effect and industrial output effect for Chemicals, Nonmetals, Metals, and Manufacture of equipment were much larger than those of other sectors. The results revealed that production technological innovations, phase-out of outdated capacities of energy intensive industries, and industrial restructuring are crucial for reduction in industrial FEU of cities. This study also provided reference to reasonable industrial layout among cities and exertion of technological advantages from a national perspective.
Highlights
Industrialization, urbanization, and economic growth are accompanied by continuously increasing energy demand and consumption, which lead to progressively serious greenhouse gases (GHGs) and atmospheric pollutant emissions, especially in developing countries [1,2,3]
Only total industrial output in Shenyang presented a trend as first increasing and decreasing, which was similar to the trend in industrial final energy use (FEU)
The variations in industrial final energy use (FEU) and the determinants of changes in aggregate and sectoral FEU during 2005–2010 and 2010–2015 were investigated by using the Logarithmic Mean Divisia Index (LMDI) approach
Summary
Industrialization, urbanization, and economic growth are accompanied by continuously increasing energy demand and consumption, which lead to progressively serious greenhouse gases (GHGs) and atmospheric pollutant emissions, especially in developing countries [1,2,3]. Experiencing a rapid growth stage of economy, China, a middle-income country, has become the world’s leading energy consumer (since 2009) and carbon dioxide (CO2) emitter (since 2006) [4,5]. Coal consumption dominated the total primary energy consumption, accounting for 60.4% [6], which has induced the largest emission amount of CO2 and air pollutants. China is still in the progress of rapid urbanization (projected to rise to 60% by 2020) and industrialization, which makes China confronted with challenges of increasing energy demand and related environmental issues [4]
