环境规制相对力度变化对FDI的影响分析

本文利用1995-2007年间41个投资来源国和地区的数据,把41个投资来源国和地区分为25个发达国家与16个发展中国家(地区)两类,重点研究中国环境规制相对力度的变化对FDI的影响,并考察了借贷成本、双边贸易关系、经济发展水平的相似性等影响因素,运用面板数据进行中国环境规制相对力度的变化对FDI的影响的实证检验,为中国选择FDI的类型提供理论依据.本文的研究结论表明;中国——相对于投资来源国——环境规制相对力度越严格,来自发展中国家(地区)的FDI将减少；而来自发达国家的FDI并不受影响.产生这一结果的原因在于,不同外商直接投资来源国企业环保技术水平的差异导致其对环境规制的敏感程度不同.在上述结论的基础上,论文对中国选择FDI的类型从外资的来源结构、产业结构、环境技术三个方面提出了相应的政策建议.     

珠江三角洲区域一体化的水利政策法规体系研究

建立珠江三角洲区域一体化的水利政策法规体系是珠江三角洲国民经济社会发展和水利现代化建设的需要。从珠江三角洲地区现行水利政策法规存在的问题入手,开展珠江三角洲区域一体化的政策法规体系研究。结果表明：珠江三角洲地区现行水利政策法规体系仍很不完善,许多立、改、废工作亟待进行,2008年水政执法有效率总体较高,但很少在珠江三角洲层面开展区域一体化的联合执法,珠江三角洲水利政策法规体系建设应重点加强与水利现代化建设、水资源一体化配置、保护及管理相关的政策法规,进而建立统一协调、快速高效的区域一体化的联合执法体系。

A ban on one is a boon for the other: Strict gasoline content rules and implicit ethanol blending mandates

Ethanol and methyl-tertiary butyl ether (MTBE) were close substitutes in the gasoline additives market until MTBE was banned due to the concerns about groundwater contamination, leading to a sudden and dramatic substitution toward ethanol as an alternative oxygenate and octane-booster. We use variation in the timing of MTBE bans across states to identify their effects on gasoline prices. We find that state bans increased reformulated gasoline prices by 3–6 cents in non-Midwestern states for which the bans were binding, with larger impacts during times of high ethanol prices relative to MTBE and crude oil. We find qualitatively similar, yet smaller effects for conventional gasoline. We argue on the basis of a simple conceptual model and supporting empirical evidence that these bans functioned as implicit ethanol blending mandates in areas that were previously using MTBE to comply with strict environmental constraints. Overall, our results are consistent with the theoretical prediction that mandating a minimum market share for a more costly alternative fuel—either directly, or implicitly through a ban on the preferred conventional fuel—will inevitably increase fuel prices in a competitive market.     

国家公园分区管控的实践总结与制度进阶

分区管控是实现国家公园严格保护与合理利用双重目的的基础制度,也是保障原住居民发展权益的有效途径。梳理总结各试点公园的分区管控制度,本文发现存在实体规范各行其是、程序规范先天不足、责任规范流于形式的问题,难以实现保护优先、兼顾利用之间的关系。国家公园法应统一分区标准,采取二阶结构的分区管控制度,首先以世界自然保护联盟提出的"三圈层"模式划分严格保护区、缓冲区、一般控制区,进而将一般控制区划分为游憩展示区和传统利用区,并将生态保育修复区作为特别的"动态分区"。同时,提高国家公园规划及变更的审批权限并完善分区管控的法律责任,以实现实质的差别化管控和严格规范的管理。     

美国恶臭污染管理及测试方法

介绍了美国目前的恶臭法规和政策问题。在最近几年中,恶臭标准化问题已经取得了令人瞩目的进展。在美国,大气和废物管理协会(A＆WMA)的EE-6恶臭委员会向美国试验与材料协会(ASTM)转交了关于美国试验与材料协会(ASTM)E-679-91方法的建议性替代方案。另外,该方案推荐对嗅觉计使用最小的流量速率3L/min。然而美国大量的恶臭实验室采用了接近20L/min流量速率的欧洲标准。作者提出疑问:美国标准中调整后的嗅觉测量法中采用较低的流量速率和测定值是否与欧洲标准中采用的较高的流量速率和较高的恶臭测定值存在矛盾呢?     

Environmental problems and environmental regulations in Western Europe, 1980–1989

Environmental problems are a function of the process of economic development and the ability to mitigate the problems through regulation. An historical analysis helps to show how the problems have been solved thus far. The objective of this investigation is to present an overview of environmental problems and the corresponding regulations in Western Europe during the 1980s. Environmental problems for 18 Western European countries were identified from abstracts from a data base on environmental literature. The 1977 findings were systematized on the basis of 20 key words according to source and impact, and a new data base was established. The data showed that the main environmental problems in Western Europe were: energy production/acid rain, nuclear power/waste, air pollution/climate, heavy metals, pesticides, water pollution, solid waste, and unforeseen accidents. Many environmental problems are common to most European countries. Regulatory measures differ significantly. In some countries environmental regulations are largely limited to the implementation of European Economic Community (EEC) directives. We have supplemented the national analyses with an examination of existing and proposed EEC regulations along with interviews with civil servants in the EEC Commission. In the 1980s, EEC environmental regulations were similar to environmental regulations in some member states. It is expected that future EEC regulations will be less reflective of those of individual member states.     

GROUND WATER HYDRAULICS CONSIDERATIONS REGARDING LANDFILLS1

ABSTRACT: Landfill siting and design guidelines or regulations differ from state to state. Most include hydrogeological criteria, referring to hydraulic conductivities, aquifers, ground water flow patterns, contaminant travel times, and distance between landfill and sensitive targets for contaminants, etc. However, almost all of the existing hydrogeological guidelines are incomplete, inconsistent, or both. The aquitard between landfill and regional aquifer frequently offers less resistance to leachate migration than compliance with regulations may suggest. Residence times of leachate, that makes it through the landfill liner, is often overestimated. Monitoring wells in the regional aquifer are unreliable detectors of local leaks in a landfill. If a landfill does leak, costly aquifer restoration is called for. For traditional landfill designs, ground water monitoring considerations suggest the siting over homogeneous sand and gravel aquifers, rather than over complex till environments. An alternative landfill design criterion is suggested, which is based on a negative hydraulic gradient underneath the landfill. This design guarantees ground water protection, simplifies landfill monitoring, and generally enhances the landfill economy.     

Grab versus composite sampling: A primer for the manager and engineer

Effluent subsamples are usually aggregated into flow or time proportional samples before analysis. Although this provides information on average process conditions, that on process variability is lost by compositing. Fisher's information is defined and used to estimate the loss due to compositing. The results of simulations based on parameters derived from actual waste streams support the fact that random grabs serve as well as composite samples for monitoring purposes. These findings favor changes in regulatory practice to allow compliance to be demonstrated by grab sample averages. Reporting requirements based on moving averages are shown to be inferior to those based on averages taken over nonoverlapping time periods.     

A regulatory view on science and predictive models

A lot of scientific knowledge is required to carry out and enforce environmental regulations. The paper deals with the relationship between law and science from a legal perspective. First, some difficulties in using science to carry out environmental regulations are outlined. After this, some legal concepts which try to cope with the problems are presented. Aspects discussed are the precautionary principle, the legal concept of 'state of the art', general standard setting, the flexibility of the regulations, and procedural regulations for the standard-setting process. Finally, the new challenge for science that derives from the legal demand of an integrated approach to environmental protection is addressed.
