经济增长质量与能源效率是一致的吗?

论文从全社会节能的角度提出全社会能源效率的概念,构建了经济增长质量指标体系,并基于1997—2007 年中国30 个省份的面板数据,采用Malmquist DEA方法测算了广义技术进步指数并进行分解,然后运用面板方法分析了经济增长质量与能源效率的作用机制,研究结果表明经济增长质量与能源效率是不完全一致的,具体表现为:改善环境质量与提高能源效率是一致的,技术进步与产业结构升级能够促进能源效率,但出口比重的增加和生活水平的提高会抑制能源效率的改进。技术进步、技术效率、纯技术效率和规模效率对全社会能源效率有正向影响,技术效率的作用大于技术进步,纯技术效率和规模效率的下降削弱了技术进步的正向作用。     

Principal sustainability components: empirical analysis of synergies between the three pillars of sustainability

Starting from the concept of three fundamental sustainability dimensions (environmental, social, and economic), this study investigated professional contributions to sustainability by means of principal component analysis (PCA). Graduates from the Environmental Sciences program (N?=?542) at ETH Zurich described their best professional contributions to sustainable development. Next, they evaluated whether their best practice example contributed to achieving any of the five environmental, social, and economic objectives of the Swiss national sustainability strategy. These judgments served as the basis for a PCA aiming to identify principal sustainability components (PSCs) covering typical synergies between sustainability objectives within and transcending the three fundamental dimensions. Three PSCs capturing important synergies were identified. PSC 1 Product and Process Development reflects how ecological innovation and modernization can generate social and economic benefits and at the same time facilitate the reduction in use of as well as the responsible use of natural resources. PSC 2 Education and Social Economics reflects how educational activities and sociocultural sustainability initiatives can simultaneously promote income and employment, social and human capital, and free personal development. PSC 3 Protection of Nature and Humans covers the synergetic benefits which protection of natural spaces and biodiversity and the reduction of environmental risks have for the protection of health and safety of the population. The study also revealed that integration of environmental, social, and economic aspects is often connected to conflicts between these dimensions. However, contributions which consider the economic situation of future generations or enhance social and human capital achieved considerable integration but showed no inclination toward such conflicts.     

Prioritising development planning in the Indian semi-arid Deccan using sustainable livelihood security index approach

This paper presents the status of sustainable livelihood security index (SLSI) of Karnataka, the most drought prone state in the Southern part of India. Computation of ecological security index, economic efficiency index and social equity index, and finally SLSI were carried out at the district level for the entire state, using empirical data. The selected indicators were first normalised, and then using estimated weights, indices were computed. The results indicate that the state has a very low SLSI with only 27.6% of total geographical area (TGA) and 21.7% of population being placed in the ‘sustainable’ and ‘highly sustainable’ categories (covering 10 districts) while only 34% of the TGA covering six districts falls in the ‘moderately sustainable’ category. The remaining area, confined mostly to the northern parts of the state, comprising 14 districts (51.8% of the state’s TGA) is categorised as ‘less sustainable’ and ‘very less sustainable’ exposing 44.4% (27.14 million) of state’s population to the perils of uncertain rainfall, high soil erosion rates, high social inequality and poor resource use efficiency. There is an urgent need to reorient development programmes and prioritise development investments in these vulnerable districts so that they are provided resources and opportunities to improve their ecological (more forest cover and less soil erosion), economic (higher agricultural productivity) and social (improved health and education facilities and rural infrastructure) status and achieve sustainable levels of livelihood.

内蒙古经济发展与环境污染之间关系的检验

利用内蒙古1986-2009年间的6类环境污染指标和人均GDP数据,基于VAR计量技术,通过变量平稳性和协整检验,Granger因果检验和脉冲响应分析对经济增长与环境污染的关系及其动态性进行了实证研究。结果显示:①当内蒙古粉尘排放量增长率、 工业固体废弃物产生量增长率、 工业二氧化硫排放量增长率和工业烟尘排放量增长率各增加1%时,人均GDP分别降低0.068%、 0.411%、 0.380%以及0.418%;当工业废气排放量增长率和工业废水排放量增长率分别增加1%时,人均GDP分别上升1.305%和1.601%。②人均GDP变化是工业固体废弃物产生量和工业废气排放量变化的Granger原因,但各污染物排放并不是人均GDP变化的Granger原因,这与研究期间内蒙古处于工业化尤其是工业中的采矿业发达的事实吻合。③人均GDP增长率对来自环境变量增长率的冲击影响其响应表现为在第1期均为0,从长期响应来看,给粉尘和废水排放增长率一个正的冲击,人均GDP增长率的响应为持续的降低;对来自废气排放增长率冲击响应函数图在前4期表现出"增长-降低-增长"的趋势,而在后6期表现为缓缓下降;对来自固体废弃物产生量增长率和二氧化硫排放量增长率冲击响应不明显;对来自烟尘排放量增长率的冲击其响应在第2期达到最大值,随后也呈递减趋势。④从方差分析的结果看,不考虑GDP自身的贡献率,内蒙古环境污染指标排放增长率对人均GDP增长率贡献率较小,而在不考虑内蒙古各个环境污染指标排放增长率自身的贡献率的情况下,内蒙古人均GDP增长率对环境污染指标排放的增长率的贡献较高。这进一步说明了内蒙古环境各污染因子排放量的增多并没有大幅度促进人均GDP的增长,但是人均GDP增长却带动了工业污染物排放的增长。
