基于数据包络分析（DEA）的中国节能降耗实证研究

能源是人类赖以生存的基础,也是社会经济可持续发展的重要约束,能源效率越来越受到国际社会的关注.我国"十一五"规划纲要中明确提出了到2010年实现GDP能耗降低20%的量化指标,节能降耗已经上升为基本国策.通过对2000-2007年中国能源利用状况的分析以及各省能源效率的测算,得出中国能源消费结构不合理、能源效率区域差异较大的结论.

介绍了烟气排放控制工程中OHS风险控制的方法,并以香港青山“B”电厂4X680MW机组排放控制工程（CPBEC）为例,阐述了目前国内外环保项目在OHS风险管理方面的差距和改进措施。     

国务院出台2009年立法计划

国务院近日印发了《国务院2009年立法工作计划》（以下简称《工作计划》）。按照《工作计划》,今年,《大气污染法（修订）》、《环境监测管理条例》、《畜禽养殖污染防治条例》等与节约能源资源、保护生态环境有关的法律、法规将制定、修订,或提请全国人大委员会审议。     

应对夏季传染病 上海医院“有泻必检”

针对夏季霍乱、菌痢、乙脑等传染病和登革热等病媒传染病容易暴发流行的危险因素,上海市卫生局4月20日作出部署,医疗机构5月1日前必须全部开设或恢复肠道门诊,而且"有泻必检",全部进行霍乱病原学相关项目检测,做到早发现、早隔离、早诊断、早治疗。

Technological Progress, Structural Change and China＇s Energy Efficiency

China has witnessed rapid economic development since 1978, and during the time, energy production and consumption developed at a tremendous speed as well. Energy efficiency which can be measured by energy consumption per unit of GDP, however, experienced continuous decrease. Theoretically, the change of energy efficiency can be attributed to industry structural change and technological change. In order to explain the transformation of Chinese energy efficiency, we adopt logarithmic mean Divisia index techniques to decompose changes in energy intensity in the period of 1994-2005. We find that technological change is the dominant contributor in the decline of energy intensity, but the contribution has declined since 2001. The change in industry structure has decreased the energy intensity before 1998, but raised the intensity after 1998. Decomposed technological effects for all sectors indicate that technological progresses in high energy consuming industries such as raw chemical materials and chemical products, smelting and pressing of ferrous metals, manufacture of non-metallic mineral products and household contribute are the principal drivers of China＇s declining energy intensity.     

Analysis of the Energy Embodied in Foreign Goods Trade of China

In recent years, scientists have been increasingly interested in the energy embodied in traded goods among countries. In this article, the direct energy intensities in various economic sectors of China were calculated with the data of energy consumption and output value of each sector, and the input-output table was used to estimate the external energy consumption. The total energy intensity of all sectors was then obtained. From the data of international trade, the energy embodied in goods trade of China was estimated for the period of 1994-2001. During this period, the average energy intensity of imported goods was always higher than that of exported ones. As a country with a surplus in international goods trade, China actually imported net embodied energy in the past few years. The net embodied energy imported was at the same magnitude of the imported energy in the form of fossil fuels.     

湖泊生态安全评估项目简介

由于湖泊流域社会经济快速发展,而污染治理设施滞后,氮,磷等污染负荷削减不力,致使我国众多湖泊水库长期接纳过量营养盐,湖泊水库富营养化程度普遍较高,湖泊水库水体处于“水华”频发的高生态风险状态之下,我国大中型湖泊水库的富营养化不仅导致水生生态系统及其服务多功能的退化,其引起的频率水华暴发现状已直接影响到湖泊水库周边及下游城镇,     

西南草根环保NGO的生存与发展

北京以外,西南地区应该是中国草根环保NGO数量最多、项目最集中、开展活动历史最悠久、取得成绩也最大的区域。北京是中国的政治、文化、经济中心,天然具备最先获得政府相关政策的信息和方便联络的政治优势。目前中国草根NGO的大部分资金来自国外的资助,而且申请资金的信息大多在北京发布。所以北京的草根NGO在获得国际、国内项目资金的支持方面具有信息、地域和人才的优势,NGO的数量增长迅速,NGO的规模也在不断壮大,这是中国任何一个城市和一个区域都无可比拟的。     

破解煤电之争困局

在我国,处于产业上下游的煤炭和电力行业,经常因为电煤价格问题不能达成一致而发生贸易摩擦。在当今经济危机背景下,煤电之间对于电煤价格问题的分歧进一步加剧。在2009年全国煤炭产运需衔接合同汇总会上,五大发电集团未与电煤供应方签订重点合同。电力是国民经济的命脉,电力价格与所有企业的成本息息相关。煤电之争引起了社会各界的深切关注。
