环境规制的蓝色红利效应研究

利用中国工业企业数据库2004~2009年制造业企业数据,以清洁生产目录标准的政策实施为外生冲击事件,基于倍差估计法（DID）实证检验了环境规制对企业盈利能力、盈利质量、波特效应和管理创新成本等蓝色红利的影响.结果发现：环境规制显著提升了制造企业的利润率和企业的现金流充裕性,改善了企业的盈利能力和盈利质量;环境规制显著降低了企业管理创新成本,但波特效应不显著.环境规制的蓝色红利效应存在地方策略互动、企业规模和所有制的异质性：地方政府之间的策略性不合作抑制了环境规制蓝色红利效应.企业规模的扩大提高了管理创新成本,但强化其他相关的蓝色红利效应.环境规制对国有企业的利润率、现金流以及全要素生产率的改善作用强于非国有企业,但更有助于降低非国有企业的管理创新成本.

MULTIPLE CRITERIA ANALYSIS FOR WATER QUALITY MANAGEMENT IN THE NITRA BASIN1

ABSTRACT: This paper presents the implementation of one element of a decision support system (DSS) for regional water quality management, applied to the Nitra River Basin in Slovakia. A model-based, aspiration-led methodology for multicriteria decision support has been used for the study. Several reusable, modular software tools have been developed and implemented: a problem-specific generator to produce the core part of the mathematical programming model, tools for the generation and interactive modification of multicriteria problems, and a solver for the resulting mixed-integer optimization problem. Provided in the paper are the following: a complete formulation of the mathematical model (including the imbedded water quality model), a summary of the aspiration-reservation-led multiple criteria optimization approach applied to decision support, and an overview of results that illustrate the applied approach and provide some interesting insights to the case study.     

The Precautionary Principle and Chemicals Regulation: Past Achievements and Future Possibilities (8 pages)

Background, Aim and Scope

The paper investigates the development of the institutional basis of the present modes of chemicals regulation and management, with special attention to interrelations with the precautionary principle. Main Features: The paper elucidates on how the precautionary principle has been shaped in relation to chemicals regulation and management since Carson's Silent Spring (years before the principle was confirmed as a policy-principle in German and European legislation. Furthermore, it is examined how the precautionary principle interacted with the development of the present chemicals regulatory regime, in a complex interplay within the OECD and Member Countries. The present modes of precaution in the new EU chemical legislation – REACH – are investigated with respect to the precautionary principle, and tested against two contemporary problems; brominated flame retardants and endocrine disrupting substances. Results: The analysis demonstrates the changing character of the integration of the precautionary principle. The main tendencies are from implicit to more explicit precaution and from a closed expert-orientation towards a more deliberative approach to scientific knowledge and uncertainty. The results demonstrate that the precautionary principle is manifest in both the design of the testing strategy and in policy provisions. In particular, the substitution of hazardous substances with less hazardous is important. Discussion: Despite explicit attention to the precautionary principle, is the present reformulation of the European Chemicals policy in danger of falling into loop-holes that equal problems related to the present regulation of existing chemicals? 'Precaution' has been reduced virtually to an abstract concept that is more or less devoid of practical meaning in the regulatory process. Conclusions: It is concluded that the role of the precautionary principle in chemicals regulation will require continued scrutiny in the future shaping of the REACH strategy. Perspectives: Continued development of robust and precaution-based chemicals regulation will have to involve both new data-generation strategies and new forms of political decision-making, with special attention given to transparency and deliberative policymaking.     

Good news for environmental self-regulation? Finding the right link

We investigate the stock market response to firm disclosure of positive environmental information and the link from that information to environmental outcomes. We classify environmental media releases by informational content and value relevance, and assess the abnormal stock returns of each type of event. While announcements of future environmental activities lead to the largest favorable stock market reactions, there is no guaranteed link from this type of information to environmental outcomes. Further analysis of the abnormal returns shows that the magnitude of the stock market reaction depends on firm financial characteristics across all event types rather than on firm environmental performance. Our results indicate that the ability for voluntary environmental information disclosure to induce environmental self-regulation is limited to the extent that firms are able to follow through with their announcements of planned environmental activities.     

土壤污染风险规制中的行政裁量研究

我国土壤污染风险规制在专家遴选标准、建设用地和农用地污染风险管控要求，以及风险管控措施等方面存在不同程度的行政裁量。社会理性和科学理性的缺失形成了土壤污染风险行政裁量困局。土壤污染信息制度中“适时公开”的规定使得公众缺乏必要污染信息，弱化其参与程度，导致对行政决定合法性的质疑。此外，土壤污染风险管控标准中专家遴选标准和论证规则的欠缺导致土壤污染风险规制科学理性的缺失。为此，需要建构关照事实和规范的协商式行政裁量模式，强调公众的实质性参与以弥合技术理性和公众理性的鸿沟。同时，在程序上确定专家遴选标准和风险管控标准的论证规则以保证土壤污染风险管控的科学性和客观性。在不妨碍行政裁量权灵活性和能动性的前提下，规范行政裁量权的行使，控制行政裁量权的滥用。     

矿井热宽温度环境人体热健康分区热调节模型*

为评价矿井热环境中工人职业健康安全状况，提出矿井热宽温度环境人体热健康状态的基本特征与生理要求，分析热宽温度环境人体分区热调节规律与热健康状态的对应关系。基于生物控制论的观点，提出热宽温度范围内不同热应力作用下人体分区热调节机制，建立人体分区热调节模型。结果表明:模型能实现对环境热应力作用下人体物理热平衡状态与生理状态的参数化描述，揭示多因素作用下人体热健康状态的热应力边界与变化规律。分区热调节模型提供了人体热健康状态定量模拟平台，通过参数调整可使模型适应研究需求，模型为井下热环境工人职业健康安全状况分析与评价提供了可参考的思路与方法。
