  • assessing the policy impacts on non ferrous Metals Industry s co2 reduction evidence from china
    Journal of Cleaner Production, 2018
    Co-Authors: Dmaris Coffman, Yiming Wei
    Abstract:

    Abstract The nonferrous Metals Industry (NMI) consumes a great amount of energy, and is a typical high CO2 emission sector. The NMI is one of the eight most concerning industries in the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report. In this study, we summarized policies that impact Chinese NMI's development and grouped them into three types: energy structure policies, energy efficiency improving policies and production-scale policies. Based on those quantitative policy goals, a bottom-up model has been developed to study the CO2 emissions of five NMI's major sub-sectors from 2010 to 2030. The results showed that if China's central government could stick to the CO2 reduction policy strength of 13th Five-Year Plan (2016–2020), then the copper, lead and zinc industries can reach their emissions peak before 2030. Furthermore, if the Chinese government restricts the production of primary aluminum of 46.2 million tons in 2025, then the CO2 emissions of China's non-ferrous Industry could reach the peak in that year, when the CO2 emissions peak is 297 million tons. Having benefited from the effective CO2 reduction policies of NMI, China may reach its ambitious CO2 peaking goals more easily.

  • environmental regulation and energy environmental performance empirical evidence from china s non ferrous Metals Industry
    Journal of Environmental Management, 2020
    Co-Authors: Xing Chen
    Abstract:

    Abstract Environmental regulation (ER) is regarded as an important driver of environmental improvement. Taking China's non-ferrous Metals Industry (NFMI) as a sample, this paper discusses the relationship between ER and energy environmental performance (EEPI) in two stages, and tests the effectiveness of the “strong” Porter hypothesis. In the first stage, this paper uses the global environment DEA to construct the competitiveness index, EEPI, which represents “green” development. In the second stage, we explore the relationship between two types of ER and EEPI by using the panel Tobit model and considers the non-linear characteristics of ER and regional heterogeneity. Moreover, a mechanism analysis is conducted. The results show that: (1) at a reasonable regulatory level, this study supports the “strong” Porter hypothesis in China's NFMI. (2) Technological innovation plays a mediating effect between environmental regulation and EEPI. (3) From a national perspective, there is a significant inverted U-shaped non-linear relationship between environmental expenditure and EEPI, and a significant U-shaped non-linear relationship between environmental investment and EEPI. (4) Regional samples present heterogeneous results between ER and EEPI. Based on the conclusions, we believe that environmental regulation policies should take into account regional differences and incorporate diversified green innovations to achieve sustainable development.

  • how technological progress affects input substitution and energy efficiency in china a case of the non ferrous Metals Industry
    Energy, 2020
    Co-Authors: Boqiang Lin, Xing Chen
    Abstract:

    Abstract Technological progress leads to factor shares change by changing the marginal productivity of factors or the substitution elasticity between factors. This is a key energy issue affecting total factor energy performance. The study used data from 1980 to 2016 of China’s non-ferrous Metals Industry (CNMI). In the first part, the paper employs ridge regression to study the substitution effect and technological progress difference among factor inputs. Second, the paper analyzed the impact of technical indexes on energy performance by using the Data Envelopment Approach (DEA)-Malmquist framework. The results show a higher output elasticity of labor (0.300–0.451) than that of energy (0.289–0.403) and capital (0.230–0.346). China’s non-ferrous Metals Industry shows labor-biased technological progress. The results indicate the existence of mutual substitution relations among the three factors. The substitution elasticity among input factors shows a convergence trend. The substitution elasticity between labor and energy (1.062–1.199) emerge as the highest. This is followed by the substitution elasticity of energy for capital. In addition, the technological progress difference between the three inputs become smaller gradually. Whether from the national average or regions, energy performance has improved significantly, which benefits from the impact of technological progress and changes technical efficiency.

  • evaluating the co2 performance of china s non ferrous Metals Industry a total factor meta frontier malmquist index perspective
    Journal of Cleaner Production, 2019
    Co-Authors: Xing Chen
    Abstract:

    Abstract China is the world's largest producer and consumer of non-ferrous Metals, and the non-ferrous Metals Industry is energy- and emission-intensive. The CO2 emissions of the Industry have increased nearly four times from the level in 2000 to reach 310 million tons in 2014. To cope with the issues of CO2 emission and other environmental problems under the background of low-carbon development, it is necessary to analyze the CO2 emission performance of China's non-ferrous Metals Industry. Based on group heterogeneity, this paper uses data envelopment analysis to calculate the Shephard distance function and then uses the Shephard distance function and non-parametric meta-frontier methods to construct the meta-frontier Malmquist CO2 emission performance index (MMCPI) of China's non-ferrous Metals Industry during the period 2006–2014. The index is further decomposed into three parts: technical efficiency change, technological progress change and technological catch-up effect. The results showed that the MMCPI of China's non-ferrous Metals Industry exhibits an upward trend during the review period. The improvement in CO2 emission performance is most significant in the central region, followed by the eastern and western regions. Based on the decomposition of MMCPI, the effect of technological progress are significantly different for the different regions, indicating that more targeted policies are need for different regions.

  • technological progress and rebound effect in china s nonferrous Metals Industry an empirical study
    Energy Policy, 2017
    Co-Authors: Yufang Chen, Guoliang Zhang
    Abstract:

    As one of China's mainstay and six major energy-intensive industries, the nonferrous Metals Industry faces the intense contradiction between economic growth and energy & environment constraints. Technological progress does not only realize the energy savings, but also causes rebound effect by promoting output growth. Although the rebound effect is an important topic, there is still very little empirical research that focuses on the nonferrous Metals Industry in China. Using the LMDI method and the total factor productivity model (to calculate parameters), we estimate the size of the rebound effect in China's nonferrous Metals Industry over the period 1985–2014. According to the results, the average rebound effect is approximately 83.02% with a downward trend, which indicates that most of the expected energy savings are mitigated. The rebounds with a strong fluctuation are comparatively discussed in various periods, suggesting that China cannot count only on technological progress to save energy and reduce emission. Furthermore, the government should apply economic instruments, such as energy pricing mechanism reform, resource tax, and carbon tax, as supplements to realize the targets of energy conservation and emission reduction. Additionally, optimizing sub-sector structure and promoting substitution also play a significant role in the mitigation of the rebound effect.

  • estimates of electricity saving potential in chinese nonferrous Metals Industry
    Energy Policy, 2013
    Co-Authors: Guoliang Zhang
    Abstract:

    The paper analyzes the electricity saving potential of nonferrous Metals Industry in China. The cointegration method is applied to estimate electricity intensity of Chinese nonferrous Metals Industry, in an effort to predict future electricity saving potential. The results show that there is a long-run equilibrium between electricity intensity and factors such as R&D intensity, industrial electricity price, enterprise scale, and labor productivity. By means of scenario analysis, we evaluate different possible measures that might be adopted to narrow down the electricity efficiency gap between nonferrous Metals Industry in China and that of Japan. The results indicate that more active electricity conservation policies are needed in order to reduce the electricity intensity of Chinese nonferrous Metals Industry. We also find that the electricity efficiency gap could be significantly narrowed by 2020 if proper electricity conservation policy is adopted. Finally, based on the results of the scenario analysis, future policy priorities are suggested.

  • Analysis of energy savings potential of China's nonferrous Metals Industry
    Resources Conservation and Recycling, 2017
    Co-Authors: Yanmin Shao
    Abstract:

    Abstract China is one of the world's leading producers of refined copper, primary aluminum, lead, refined zinc, refined nickel, antimony, primary magnesium, manganese ore, tin ore, tungsten, and molybdenum. The production of the nonferrous Metals Industry is also energy-intensive, its energy consumption increased from 31.5 million tons of oil equivalent in 2000 to 112 million tons of oil equivalent in 2012, which is almost the same as Australia's total energy consumption (133 million tons of oil equivalent) in 2012. Thus, it is imperative for the Industry to reduce its energy consumption. This study tries to analyze the energy savings potential of China's nonferrous Metals Industry by employing the directional distance function approach to model the nonferrous Metals Industry's production system. Further, the energy savings ratios and energy savings amounts of the 27 administrative regions of China during 2003–2009 are also discussed. The results show that the nonferrous Metals Industry, overall, can save more than 20% in energy consumption, and that none of the 27 regions show a year-on-year decrease in their energy savings ratios. In addition, the study finds that the regions with a high proportion of output of secondary nonferrous Metals have low energy savings ratio. Another key finding of this study is that the energy savings potential significantly differed according to regional characteristics, and the energy savings opportunities are great in the central and western regions of China. Finally, this study provides several recommendations to improve the energy efficiency of the nonferrous Metals Industry.

  • productivity growth and environmental efficiency of the nonferrous Metals Industry an empirical study of china
    Journal of Cleaner Production, 2016
    Co-Authors: Yanmin Shao, Shouyang Wang
    Abstract:

    Abstract This study intends to provide an insight into China's nonferrous Metals Industry production based on the analysis of the environmental efficiency, the Malmquist productivity index (MPI), and the Malmquist–Luenberger productivity index (MLPI). The empirical experiment based on the annual data of 27 regions (including provinces, autonomous regions and municipalities) of China during 2003–2009 shows the following results. First, the Industry's environmental efficiency in the east area is mostly higher than that of the other area. Second, the Industry's average annual change of MPI and MLPI in China were 4.4% and 0.9%, respectively. This indicated that the total factor productivity growth of the Industry was overestimated if undesirable outputs were ignored. Third, the Industry's productivity was mainly affected through technological advances rather than endogenous factors such as improvements in managerial practices. Finally, during the worldwide financial crisis occurred in 2008, the Industry's MLPIs exceeded the MPIs in most regions through measures such as adjustment of the product structure and elimination of backward production capacity.
