This paper analyzes the energy efficiency of China's 30 administrative regions during the period from 1997 to 2010. Most existing studies ignored the variation of production technologies among regions in China. Taking this factor into account, we introduce a parametric metafrontier approach based on the Shephard energy distance function. For further analysis, regions in China are divided into three groups using cluster analysis. We find that the regions in group 1 (mainly the regions in the east area of China) not only have the highest energy efficiency score, but also take the lead in terms of technology gap ratio. Meanwhile, due to their backward technology levels, the average energy efficiency score of the regions in group 3 (mainly the regions in the west area of China) is particularly low. Moreover, the pooled estimation, which ignores the technology gap among the groups, tends to underestimate the energy efficiency. © 2013 Elsevier B.V.

The recently introduced atom-bond connectivity (ABC) index has been applied to study the stability of alkanes and the strain energy of cycloalkanes. In this article, the ABC index of both benzenoid systems and fluoranthene congeners is shown to depend solely on the number of vertices, hexagons and inlets. In addition, the author characterizes the extremal catacondensed benzenoid systems with the maximal and minimal ABC index. © 2012 Copyright Taylor and Francis Group, LLC.

We estimated the reduction potential of carbon dioxide emissions in the Chinese textile industry by forecasting the carbon intensity (CO2 emissions/industrial value added) in different scenarios. The Johansen co-integration technique was employed in order to establish the long term equilibrium equation. Three scenarios (Business As Usual (BAU), medium and optimum) were designed to estimate the future trend of carbon intensity in the Chinese textile industry. The results showed that energy price, energy substitution, labor productivity and technology have significant impact on the carbon intensity. Estimated to 1.49t CO2/10,000 yuan in 2010, we found that for the BAU scenario, the carbon intensity will decrease to 0.5 and 0.29t CO2/10,000 yuan by 2020 and 2025 respectively. For the medium scenario, carbon intensity will decline to 0.12t CO2/10,000 yuan. Yet by the optimum scenario, the intensity is expected to considerably decrease to 0.05t CO2/10,000 yuan by 2025. Using the BAU forecast as baseline, the quantity of reduction potential in carbon dioxide emissions is estimated to be 44.8milliontons CO2 by 2025. Considering this huge potential, we provided policy suggestions to reduce the level of CO2 emissions in the Chinese textile industry. © 2013 Elsevier Ltd.

Fossil-fuel subsidies contribute to the extensive growth of energy demand and the related carbon dioxide emissions in China. However, the process of energy price reform is slow, even though China faces increasing problems of energy scarcity and environmental deterioration. This paper focuses on analyzing fossil fuel subsidies in China by estimating subsidies scale and the implications for future reform. We begin by measuring fossil-fuel subsidies and the effects of subsidy removal in a systematic fashion during 2006-2010 using a price-gap approach. Results indicate that the oil price reform in 2009 significantly reduced China's fossil-fuel subsidies and modified the subsidy structure. Fossil-fuel subsidies scale in China was 881.94 billion CNY in 2010, which was lower than the amount in 2006, equivalent to 2.59% of the GDP. The macro-economic impacts of removing fossil-fuel subsidies are then evaluated by the computable general equilibrium (CGE) model. Results demonstrate that the economic growth and employment will be negatively affected as well as energy demand, carbon dioxide and sulfur dioxide emissions. Finally, policy implications are suggested: first, risks of government pricing of energy are far from negligible; second, an acceptable macroeconomic impact is a criterion for energy price reform in China; third, the future energy policy should focus on designing transparent, targeted and efficient energy subsidies. © 2014 Elsevier Ltd.

China's energy demand has shown characteristics of rigid growth in the current urbanization stage. This paper applied the panel data model and the cointegration model to examine the determinants of energy demand in China, and then forecasts China's energy demand based on the scenario analysis. Results demonstrate an inverted U-shaped relationship between energy demand and economic growth in the long term. In business as usual scenario, China's energy consumption will reach 6493.07 million tons of coal equivalent in 2030. The conclusions can be drawn on the basis of the comparison of characteristics between the US and China. First, energy demand has rigid growth characteristics in the rapid urbanization stage. Second, coal-dominated energy structure of China will lead to the severe problems of CO2 emissions. Third, rapid economic growth requires that energy prices should not rise substantially, so that energy conservation will be the major strategy for China's low-carbon transition. Major policy implications are: first, urbanization can be used as an opportunity for low-carbon development; second, energy price reform is crucial for China's energy sustainability. © 2013 Elsevier Ltd.

Promoting technological development to improve energy efficiency has been the primary method of energy conservation in China. However, the existence of energy rebound effect will impose negative effects on the final result of energy saving. In this article, we adopt the Malmquist index approach to estimate the contribution of technological progress to economic growth. We also employ Logarithmic mean weight Divisia index (LMDI) to measure the impact of technological improvement on the energy intensity. Based on the above, we set up a model to estimate the technology-based energy rebound effect in China. The results show that, over 1981-2009, energy rebound effect amounts averagely to 53.2%, implying that China cannot simply rely on technical means to reduce energy consumption and emission. Economic instruments should also be applied as supplements to ensure results of energy conservation and emission reduction. © 2012.

We theoretically predict giant thermoelectric effects in graphene superlattices (SLs) containing a defect barrier by using a transfer matrix approach. A great thermoelectric effect occurs near the defect mode, the magnitude of the enhancement being among the largest reported ever. It is found that the magnitude of the enhancement could be controlled by adjusting the structure parameters of graphene SLs. © 2012 Elsevier B.V.

The quantum Goos-Hänchen (GH) shift of an electron (massive Dirac fermion) at a potential step in bilayer graphene is investigated. We show that the GH shift depends on the step height, the kinetic energy of the electron and incident angle. It is found that the GH shift can be large (positive or negative) under the suitable conditions. © 2012 EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg.

We analyzed the change of energy-related carbon dioxide (CO2) emissions in the Chinese textile industry from 1986 to 2010. Decomposition analysis based on Logarithmic Mean Divisia Index method was applied and the study period was split into five time intervals for easier data management. Results show that industrial activity and energy intensity were the main determinants of change in carbon dioxide emissions. Industrial activity was the major factor that contributed to the increase of CO2 emissions. Energy intensity had a volatile trend interchanging intervals of growth (increasing and decreasing) along the study period. Furthermore, energy mix and carbon intensity equally decreased the CO2 emissions. Industrial scale, despite limited effect also contributed to the increase of CO2 emissions. In the meantime, while industrial output in the Chinese textile industry increased annually by 5% from 1986 to 2010, energy consumption grew by 4% with corresponding increase of CO2 emissions by 2%. Finally, we provide policy suggestions that may be adopted to significantly cut down CO 2 emissions from the Chinese textile industry. © 2013 Elsevier Ltd.

Subsidies to fossil-fuel consumption have made Chinas energy system fragile and unsustainable. It is necessary for China to reform fossil-fuel subsidies and reflect the resource cost and environmental cost in energy prices. Considering the life-cycle external costs, this paper estimates the scale of fossil-fuel subsidy and the true cost of renewable energy in 2010 and evaluates impacts of increasing renewable energy subsidies and phasing out fossil fuel subsidies on macro-economy and energy system in China based on scenario analysis. Simulation results show that the negative impacts on economic growth can be reduced from 4.460% to 0.432%, if only 10% of fossil fuel subsidies were removed. Increasing subsidies for renewable energy has positive impacts on macroeconomic variables. Although the economic benefits per unit of subsidies for renewable energy are lower than those for fossil fuels by 0.06-0.19 CNY, the revenue gap can be narrowed by shifting more subsidies from fossil fuels to renewables. Increasing subsidies for renewable energy helps optimize Chinas energy system in three ways: the first is making energy consumption structure cleaner; the second is improving energy efficiency; and the third is addressing the problem of imbalanced distribution and consumption of energy. © 2014 Elsevier Ltd.
