浅论国家环境权

随着全球环境的日益恶化和公民环保意识的不断增强，环境权理论迅速发展。国家环境权作为一项重要的环境权。在环境法理论逐步变革和权利内涵不断演进的趋势下，已成为法学界研究探讨的重要课题。通过分析国家环境权的国内、国际法律基础。论证了国家环境权的确立。利用类比的方法。阐述了国家环境权与其他宪法权利的不同之处。从权利义务的对等统一和国内国际两个层面。重新归纳了国家环境权的内容。初步构建了国家环境权的基本理论框架。     

最优环境税:庇古法则与税制协调

从经济学的角度对国外关于最优环境税的经典理论——庇古法则及近十年来研究的前沿内容——一般均衡模型等作出阐释，并在外部性理论的基础上通过一个一般均衡模型考察环境税的效率特性和在次优情形下最优环境税的决定因素。随后是对我国开征环境税的几点思考：环境税的课征范围应暂定为排放各种废水、废气（烟尘）和固体废弃物的行为。环境税税率的确定可以采用“反复迭代”的方法，即“环境效益优先，兼顾税收协调和收入分配等效应。”其他相关问题的处理，如环境税和其它政策手段的配合使用，环境税税收的使用等。     

SUSTAINABILITY AT THE LOCAL LEVEL: MANAGEMENT TOOLS AND MUNICIPAL TAX INCENTIVE MODEL

The implementation of sustainable development may seem a simple concept when written on paper. However to carry-out long term actions put forward by the Agenda 21 (AG21) at the local level represents one of the main challenges as municipal governments in general do not have the capacity to effectively implement the process. Regional environmental assessment (REA) has shown to be effective in supporting decision-making not only to correct environmental problems due to past unsustainable social-economic developments but also help local governments to implement sustainable actions. However this requires long-term investments of AG21 plans and projects. The allocation of regular and consistent financial resources is one of the main ingredients for the sustainable development process. But traditional plans and projects financed by national and/or international funds may not be sustainable in the long-term because they become dependent on external funding. Research demonstrate that innovative economic instruments such as ecotaxes represent a feasible alternative to sponsor local sustainability because taxes are collected permanently by the government and could be invested in continuous actions. Ecotaxes experiences have provided important reference to structure a municipal incentive model (MIM) to sponsor AG21’s environmental plans and projects on a long-term (permanent) basis. However sustainable development cannot be solely through economic investments. A comprehensive municipal environmental management scheme (MEMS) has been established to support the incentive model. The scheme seeks not only to improve local institutional framework but also incentive continuous participation of local stakeholders at all levels of society. Participatory events and the provision of incentives (educational and financial) are key to motivate society to protect the environment and support actively the sustainable development process as emphasised in the RIO-92 Conference.

Sustainability: a Dissent

Abstract:  Broadly conceived and considered in its many usages, sustainability has grave defects as a planning goal, particularly when used by conservationists: it confuses means and ends; it is vague about what is being sustained and who or what is doing the sustaining; it is uninspiring; it is little more than Pinchot-era conservation (and thus ignores the many lessons learned since then); it need not be linked to land, to the land's functioning, or to any ecological science; it need not include a moral component; it is consistent with the view of humans as all-powerful manipulators of the planet; and, in general, it is such a malleable term that its popularity provides only a facade of consensus. When sustainability is defined broadly to include the full range of economic and social aspirations, it poses the particular risk that ecological and biodiversity concerns will be cast aside in favor of more pressing human wants. Given these many defects, the conservation movement should discard the term in favor of a more alluring goal, attentive to nature and its ecological functioning. A sound goal would incorporate and distill the considerable ecological and moral wisdom accumulated since Pinchot's day while giving conservationists the rhetorical tools needed to defend the land against competing pressures. In our view, conservation would be well served by an updated variant of "land health," Aldo Leopold's ecologically grounded goal from the 1940s. Land health as an independent understanding should set the essential terms of how we live and enjoy the earth, providing the framework within which we pursue our many social and economic aims.     

区域排污权交易模型研究

本文在分析了排污权交易研究进展的基础上，指出区域污染权交易比传统的排污权交易意义更大，并提出排污权交易地区交叉补贴的设想：将发达地区的排污权交易所得向欠发达地区转移，以解决欠发达地区产业结构调整乏力以及对发达地区的二次污染和发达地区环境容量资源短缺问题。在不考虑交易成本的假设下，通过建立不同地区排污权交易模型以确定排污权交易总量及其交易价格以及交易所获净增纯收益等。太湖流域由于经济最为发达，环境问题十分突出，是目前我国最适宜率先进行区域排污权交易试点的地区。通过假定太湖流域无锡和常州两市进行排污权交易，并利用两市1991—2000年的环境统计资料等相关资料进行了验证。计算结果表明区域排污权交易不仅具有明显的经济和环境效益，而且也是协调环境区域矛盾的重要手段。因此，不同地区间进行排污权交易在我国具有重要意义，在太湖流域等经济发达地区收效尤其明显。     

Analysis of Environmental and Socio-economic Determinants Affecting Population Longevity Level at County Level in China

INTRODUCTIONIn recent thirty years, due to the decreasing fertility andincreasing life expectancy, China's population is aging ata very rapid pace and the elderly population size is keepingon growing. During the dramatic aging progress, the oldestold group in China is catching our eyes. More and moreold people of China are becoming the oldest old. Theextremely old population (aged 80 and above) is increasingat 5.1% annually, while the old population above 65 isincreasing at 2.9%, and the…     

A Marine Pollution Study of Northeast Coastal Water Off Taiwan Island

The coastal water of northeast Taiwan island, called 'Yin-Yang Hai' for its distinct yellow colour compared with blue offshore water, was investigated from 1989 to 1990 by the authors. Biological study showed the dominant species of plankton to be Copepoda, Cladocera, planktonic eggs and Diatoma. Dominant species of benthos were young crabs, Amphipoda and Annelida, with Amphipoda usually occurring in heavily polluted areas. Heavy metal data showed that the concentration of copper was high. the copper and iron concentration in algae of the intertidal zone was also high. the concentrations of iron and copper in inshore water were also higher than in offshore water. By comparison of the pH and salinity distribution of this area, we conclude that this coastal water has been polluted by acid waste water from coastal industry. the suspended solids concentration in sea water is high. Flocculation occurring at the boundary of fresh and saline water might be a reason for the distinct yellow colour of the water of this area. Further study is required.     

省以下生态转移支付制度环境保护激励效应

现有文献认为生态转移支付具有基本公共服务均等化与提升地方生态环境质量双目标,而目标的多样性会影响地方财政转移支付资金效果及目标的实现。文章基于环保支出和农林水支出的中介与调节效应,对生态转移支付的生态环境目标进行了理论分析,利用2010—2018年甘肃、贵州、湖北及河南四省的199个县的面板数据进行实证检验。实证研究表明:在样本期内,生态转移支付促进了地方生态环境质量的提升,中介效应和调节效应模型的结果表明,中国地方生态转移支付资金对辖区环境保护效果中,环境保护支出起到部分中介效应,农林水支出不仅调节了生态转移支付的地方环境保护支出效果,而且调节了环境保护支出对地方环境质量的影响。因此,由于地方政府具有环境治理信息优势,省以下制度目标更能体现辖区生态需求,省对县生态转移支付制度会有效促进地方生态环境质量的改善,环保激励效应较为明显。同时,县级地方政府应该逐步摆脱"先污染后治理"的路径依赖,逐步转向经济与环境"双目标协同发展"模式。为了协同生态转移支付的双目标,"自下而上参与式决策"可以作为环境治理的有益补充,通过地方政府多元化实践改善环境质量。     

长江经济带突发水污染风险分区研究

长江经济带突发水污染事件频发,对区域人群健康和生态安全造成严峻挑战.环境风险分区是环境风险管理的基础和有效工具.本研究以2015年为基准年,基于环境统计数据、DEM数据、水质监测断面数据和基础地理数据,综合考虑了水系流向、水系级别及水质等因素,以1 km×1 km的网格为基本单元,对长江经济带开展突发水污染风险分区.结果表明:①高风险区面积为3348.9 km~2,占评估区总面积的0.16%;较高风险区面积为26030.7 km~2,占比1.27%;中风险区面积为97971.1 km~2,占比4.79%;低风险区面积为1916838.7 km~2,占比93.77%;②从沿长江干流两岸分布来看,高风险区面积沿长江上游至下游呈逐渐增加趋势,主要集中分布在重庆市中部、湖北省东部、安徽省东部、江苏省中西部、浙江省北部、上海市西部等地;③从沿长江主要支流两岸分布来看,高风险区主要分布在嘉陵江南段、乌江南段、汉水东段、湘江北段、赣江北段等.研究结果可为长江经济带生态环境管理提供科学依据.
