The drivers of energy intensity changes in Chinese cities: A production-theoretical decomposition analysis

The study aims at finding the energy intensity and the sources of the changes of the energy intensity of the steel and steel products industry in Thailand using the firm level data collected from the surveys and interviews of steel firms in 2005 and 2012. The study finds that the energy intensity of the industry during the decade of domestic and global economic turbulent time in the 2000s fluctuated. The intensity declined immediately after recovering from the 1997 financial and currency crises but moved in an inverted U-shaped curve when the industry went through the various changes of production structure during 2003 to 2010. The decomposition analysis based on the logarithmic mean Divisia index method finds that the source of the changes of the energy intensity of the industry was dominated by the structural change effect. The fluctuation of the energy intensity was found despite a persistent decline, albeit relatively small, in the energy intensity of individual subsectors. This calls for the need to strengthen the effect of subsector energy intensity changes to help reduce the energy intensity of the industry in the long term. The study results imply four policy measures the government should use to induce steel firms to reduce their energy intensity and thus use the energy in the most efficient way.

<div><p><em>This paper analysed the status of energy intensity of economic sectors (agriculture, industry, commercial, residential) in MINT (Mexico, Indonesia, Nigeria, Turkey) countries and its implications for sustainable development. We utilised descriptive statistics as well as the Logarithmic Mean Divisia Index (LMDI) decomposition analysis to examine energy and efficiency trends, from 1980-2013, in MINT countries. Empirical results indicate inefficient energy use in the residential and industrial sectors of Nigeria and Indonesia. The analysis also indicates that income/output growth (activity effect) contributed to an increase in sectoral energy consumption of MINT countries. It also revealed that while structural effects contributed to a reduction in energy consumption in virtually all the sectors in Turkey and Mexico, it contributed to an increase in energy consumption of the residential, industrial and commercial sectors of Indonesia and Nigeria in virtually all the periods. These results suggest that a policy framework that emphasizes the utilization of energy efficient technologies especially electricity infrastructural development aimed at energy service availability, accessibility and affordability will help to trigger desirable economic development and ensure rapid sustainable development of MINT economies.</em></p></div>

There exists an important awareness for reduction of CO2 emissions to obtain a sustainable world. Together with this, there is a great deal of interest for decomposition analysis to see the accelerating and decelerating factors of CO2 emissions. The aim of this project is to decompose CO2 emissions in economic sectors for the two superpowers of Middle East, Iran and Turkey, over the time period between 1990 and 2010, for Turkey obtained a rapid growth performance in recent years and Iran which is the energy superpower of the world. Refined Laspeyres Index decomposition method and a consistent data gathered from the World Bank’s and UN’s databases have been used during the analysis. Five main sectors (agriculture, manufacturing, transportation, construction and other service sectors) and four main impacts (scale effect, composition effect, energy intensity effect and carbon intensity effect) have been considered to see the increasing and decreasing factors of CO2 emissions. Various interesting results are observed for both of the countries, for each of the economic sectors. Generally scale effect and energy intensity effect are the dominant impacts for all sectors of both countries. However composition effect and carbon intensity effect are also important contributors for economic activities of these two countries. Overall, our analysis showed that these two countries should pay attention for energy intensity and sustainable economic growth.
