中国环保行政体制结构初探

环保行政体制结构是环保行政组织系统的基本框架,是实现环保行政管理职能的组织方式。我国长期以来的环保行政体制改革较为关注机构地位提升与管理职能强化,环保行政体制的结构较少得到关注。对环保行政体制结构的分析揭示了在机构地位提升与管理职能得到强化的前提下我国环保行政管理依然面临执法监督难、部门协调难等问难题的深层体制原因。本文首先根据组织行为学的基本原理,提出我国环保行政体制的矩阵结构模式,这一矩阵结构在纵向上存在双权威系统,横向上协调关系较为薄弱,从而造成环保监管权威弱化。其次,基于对我国地方环保行政体制改革效果的调查,指出我国环保行政体制结构出的了若干变化。最后,结合我国"十二五"时期落实国家环保意志的基本要求,提出改善我国环保行政体制结构的若干政策建议,即在基层改善体制结构中的双权威系统,并以流域水环境管理体制创新为大部门体制改革突破点,探索环境管理职能组织方式的优化途径。     

土壤原位覆盖对底泥的修复作用研究

在高度厌氧底泥和富营养化水体构成的模拟生态系统中,采用土壤和硅藻土进行原位覆盖,研究了覆盖技术对水．沉积物界面微环境的改善作用和不同覆盖材料对苦草生长的影响。这2种底质覆盖后,表层底泥氧化还原电位（Eh）分别提高了48．37％和46．77％,底层水体的溶解氧消耗降低,水体中的总氮（TN）和总磷（TP）含量降低;与对照箱体的苦草死亡相比,经过土壤和硅藻土覆盖的箱体中苦草正常萌发、定植和生长;硅藻土箱体苦草的生物量、叶绿素和根茎比均高于土壤覆盖箱体。因此,原位覆盖能有效改善底层水体和表层底泥的氧化还原环境,隔绝污染底泥和延缓营养盐释放,为沉水植物种子萌发和幼苗生长提供有利的生境条件。     

政府减贫行为的动态效应——中国农村减贫问题的SVAR模型实证分析(1990-2008)

脱贫人口返贫率偏高是中国农村贫困问题的一个显著特征.这种客观现实要求我们,应该仔细考察农村贫困发生率、贫困深度和贫困强度对政府干预行为的跨期响应,从而动态地而不是静态地评价政府减贫行为绩效.本文将普惠式的农村农业发展政策与扶贫政策一起纳入减贫分析框架,构建一个结构向量自回归模型(SVAR)模型,以弥补现有文献用多变量时间序列数据通过单方程模型回归分析的局限,从SVAR模型中获得结构冲击响应函数,动态地评价政府行为的减贫效应.实证分析表明,目前的政府行为,无论是普惠式的农村农业发展政策,还是瞄准贫困人口的扶贫政策,对农村贫困的政策干预都没有形成持久的影响,冲击响应衰减很快.为了降低脱贫人口返贫率,政府减贫政策的目标应定位于提升贫困人口的自身发展能力,扩展贫困人口参与经济增长的机会,使经济增长成为他们获取稳定收益的源泉.     

试论低碳经济背景下的政府职能

伴随着经济与社会的进步,能源短缺与环境污染正愈演愈烈,迫切需要由高碳经济转向低碳经济。中国目前的发展模式与消费结构仍处于高碳状态,因此发展低碳经济势在必行。政府作为经济活动的有机组成部分,应当在发展低碳经济的过程中履行好其对外交流、对内调控的政府职能。     

'It'll never happen to me': understanding public awareness of local flood risk

Following the severe flood events of 1998 and 2000, the United Kingdom's Environment Agency prioritised the need to increase public flood risk awareness. Drawing on data collected during research undertaken for the Environment Agency, this paper contributes to understanding of one aspect of flood awareness: people's recognition that their property is in an area that is potentially at risk of flooding. Quantitative analyses indicate that class is the most influential factor in predicting flood risk awareness, followed by flood experience and length of time in residence. There are also significant area differences. Our qualitative work explores how those defined as 'at risk' account for their lack of awareness or concern about their risk status. We conclude that the problem is often not simply a lack of awareness, but rather, assessments of local risk based on experience that underestimate the impact of rare or extreme events. We underline the importance of engaging with local perspectives on risk and making local people part of 'awareness-raising' processes.     

Emergency preparedness consultants at the local government level: the Israeli experience

This study evaluates the effectiveness of the Municipal Emergency Consultation project in eight Israeli local authorities. The initiative centres on the appointment of independent emergency preparedness consultants entrusted with tailoring an emergency preparedness package to suit the specific needs of each locality. Regarding emergency preparedness improvements, in all of the municipalities examined, a concept of municipal emergency operation was consolidated and the derived emergency plan tested. Emergency work processes were structured and service‐level agreements reached between municipality departments. Where necessary, a‐linear patterns of municipal functioning in an emergency were established. Concerning a ‘spillover’ of emergency preparedness improvements into routine operations, and a ‘spillover’ of routine management improvements into local emergency preparedness, two municipalities near Gaza, which typically function in an emergency routine, saw a significant ‘spillover’ of emergency preparedness into routine functioning. In other localities, local managers chose to improve a number of municipal structures and procedures in times of routine functioning, which are also related to the functioning of the municipality during an emergency.     

Analysis of the Difference of the Basic Pension by Regions

Nowadays, the disparity of the basic pension in local regions of China can be described as follows: the low level of the unification of the basic pension systems, the large disparity of the level of the basic pension, and unfairness of the enterprises’ payment for the basic pension in different local regions in China. These have already brought many negative influences, which have greatly held back the development of the society and national economy. We should build the basic pension system in all local regions of China as a whole, which can cover all people and decrease the disparity in different local regions in China.     

The Economic and Environmental Outcomes of Microfinance Projects: An Indian Case Study

Microfinance projects now seek to achieve improvement in environmental quality in addition to poverty alleviation. Achievement of these goals may depend upon the economic and environmental impact of microfinance businesses. This study is a quantitative analysis of these outcomes for Ecodevelopment, an Indian microfinance project, which aims to prevent forest degradation by poverty alleviation. The study divides businesses into perishable goods, non-perishable goods, simple skills, and special skills and measures their economic outcome by two indicators, repayment percentage and continuity of businesses. The study examines the effect of loan amount on the economic outcome of businesses. To quantify the environmental outcome, it analyzes the use of firewood or fodder and release of pollutants by businesses. The results show that loan amount does not affect the economic outcome, special skills have best performance, and skills cause less pressure on forest resources. These results suggest the need for development of knowledge-intensive skills, involvement of institutions in the operations of business, and inclusive policies for protected area management.

公用事业民营化及其环境行为政府管制的研究

公用事业民营化的目的是在公用事业行业引入民间资本和市场竞争模式,提高公共产品服务的产出质量和效率。以电力行业的民营化为例,电力市场对于民营企业的开放能够在很大程度上提高我国电力生产水平．解决当前电力供求关系紧张的问题。但是,大量民营企业介入电力生产,由于其技术落后而导致的资源浪费以及污染物的无序排放给我国的环境保护带来了新的困扰。我们应该在科学发展观和构建社会主义和谐社会的目标指引下,加强政府对于电力企业等公用事业民营化企业生产经营活动的法律管制,同时加强和完善相关的环境立法,达到公用事业积极发展和环境保护目标实现的双赢目标。
