Changing energy intensity in China:a decomposition analysis

This study proposed a decomposition method based on the normalized quadratic shadow unit cost function to explore the determinants of the change in energy intensity in China from 1985 to 2010.The decomposition analysis indicates that (1) the improvement in technical efficiency dramatically reduced the energy intensity,whereas technological change played only a minor role,which could be attributed to a rebound effect;(2) the aggregated allocation effect was small because the change in the allocative distortion between capital and energy significantly enhanced energy intensity but was partly offset by the effect stemming from the change in the allocative distortion between capital and energy;and (3) the substitution of energy for labor increased energy intensity,but the aggregated substitution effect significantly reduced energy intensity because the substitution of capital for energy reduced energy intensity to a great extent.These findings were obtained at the national level and varied at die regional level.

随着经济发展和人民生活水平的提高,电镀产品的需求与日剧增,而电镀废水中含有大量的重金属等污染物质,如果不加以处理,任意排放,势必对环境及人类产生严重危害,因此,研究电镀废水的处理是一个热点问题.本文介绍了现有的一些电镀废水处理的主要技术和研究进展,阐述了电镀废水的不同处理工艺的特点,为电镀废水处理技术的选择提供了参考依据.     

中国水污染物排污权交易发展现状及面临的主要问题研究

在中国排污权交易制度需全面完善的背景下,水污染物排污权交易环节的建设显得更为薄弱,总体来看,中国的水污染物排污权交易还存在一些必须明确的问题和必须面对的挑战.为更好地开展水污染物排污权交易,通过分析实施水污染物排污权交易过程中的若干技术问题,提出以满足《污水综合排放标准》和《地表水环境质量标准》为前提的水污染物排污权交易计算方法,量化排污权交易可行性,预测由水污染排污权交易导致的水质变化.     

Balancing making a difference with making a living in the conservation sector

Goals play important roles in people's lives because they focus attention, mobilize effort, and sustain motivation. Understanding conservationists’ satisfaction with goal progress may provide insights into real-world environmental trends and flag risks to their well-being and motivation. We asked 2694 conservationists working globally how satisfied they were with progress toward goals important to them. We then explored how this satisfaction varied among groups, including demographic and occupational. Finally, we looked at respondents' experiences associated with goal-progress satisfaction. Many (94.0%) indicated that making a meaningful contribution to conservation was an important goal for them, and over half were satisfied or very satisfied in this area (52.5%). However, respondents were generally dissatisfied with progress on collective conservation goals (e.g., stopping species loss). Some groups were more likely to report dissatisfaction than others. For instance, those in conservation for longer tended to be less satisfied with collective goal progress (log odds –0.21, 95% credibility interval [CI] –0.32 to –0.10), but practitioners reported greater satisfaction (log odds 0.38, 95% CI 0.15–0.60). Likewise, those who were more optimistic in life (log odds 0.24, 95% CI 0.17–0.32), male (log odds 0.25, 95% CI 0.10–0.41), and working in conservation practice (log odds 0.25, 95% CI 0.08–0.43) reported greater satisfaction with individual goal progress. Free-text responses suggested widespread dissatisfaction with livelihood goals, particularly related to job security and adequate compensation. Although contributing to conservation appeared to be a source of satisfaction, slow goal progress in other areas––particularly around making a living––looked to be a source of distress and demotivation. Employers, funders, professional societies, and others should consider ways to help those in the sector make a difference while making a satisfactory living by, for example, prioritizing conservationists′ well-being when allocating funding. This support could include avoiding exploitative practices, fostering supportive work environments, and celebrating positive outcomes.     

能源生态效率评价及其与经济增长脱钩分析——以黄河流域9省区为例

采用Super—SBM模型、GML模型测度1997—2019年黄河流域9省区的能源生态效率,通过构建脱钩模型,探讨经济增长与能源消耗及能源生态效率的脱钩关系。结果发现:①黄河流域9省区能源生态效率呈增长—下降—增长的趋势,累积增长了15.3%,其中,追赶效率贡献率为41.5%,而技术进步不足。②黄河流域9省区在经济增长与能源消耗呈强脱钩—弱脱钩—强脱钩发展态势,而经济增长与能源生态效率呈强脱钩—弱脱钩—强脱钩—弱脱钩发展态势。
