中国地区间跨界污染治理的两阶段多边补偿机制研究

近年来,以雾霾、河流污染等为代表的跨界污染问题严重影响了我国经济社会的可持续协调发展。本文将跨界污染治理视为典型的地区间外溢性公共品,从公共经济学的视角出发,分析了我国地区间跨界污染治理的种种困境,并通过构建两阶段多边博弈模型,探讨了补偿机制的可行性。本文首先构建了一个跨地区的污染模型,通过中央政府干预或不干预的博弈分析发现,当污染存在地区内部及跨地区的外溢性时,如果中央政府不介入而由企业自行设定产出水平,那么企业的污染排放水平将超过社会有效率的水平。在此基础上,本文进一步构建了一个两阶段多边补偿机制博弈模型,即由中央政府设计一个地区内部企业与居民之间以及跨地区之间的补偿机制,来解决以上的无效性问题。结果显示,当企业支付的补偿金额取决于居民设定的补偿系数,而居民得到的补偿金额又取决于企业设定的补偿系数时,相互影响的博弈关系使得企业和居民从自身的利益出发,将补偿系数设定在企业污染对于居民边际损害的水平,从而企业生产水平会达到有效状态,两阶段多边补偿机制实现了有效的污染排放。本文在庇古税思想的基础上,通过放松庇古税对外部性相关信息的强假设,构建了一个两阶段多边补偿机制,即由企业缴纳庇古税后,中央将征收的庇古税补偿给居民,这样不仅内部化了企业污染给居民造成的负外部性,还进一步平衡了地区间的跨界污染治理问题。     

Factors of success and failure for transboundary environmental cooperation: projects in the Gulf of Aqaba

After signing a peace accord in 1994, joint projects were initiated between Israel and Jordan aimed at enhancing environmental protection and resource management. This paper discusses the Red Sea Dead Sea Canal, the Eilat-Aqaba Municipal Cooperation initiative, the Joint Oil Spill Contingency Plan and the Red Sea Marine Peace Park (RSMPP). The latter is an exemplar of transboundary cooperation for planning of a marine protected area and therefore the main case study. Although the RSMPP never fully materialized, analysis of what transpired provides important lessons. We examine what happened in the 20 years since the attempt to establish the RSMPP began and focus on which of its goals were achieved. As a basis for analysis this paper presents factors identified as significant to the success of transboundary protected areas (TBPAs) and uses them to compare the RSMPP to the three other initiatives. In addition to factors reported in the literature that are known to be effective for TBPA success, we found two new factors as most relevant for the RSMPP case: a peripheral geographic location and intensive work among professionals, mostly marine scientists, on the ground operating under a low profile and with limited public attention.     

论跨界河流生态受益者补偿原则

跨界河流资源及生态环境保护关系到各沿岸国的切身利益。在国际水法中确立跨界河流生态受益者补偿原则，具有非常重要的理论意义和实践价值，有着深刻的法学、经济学、伦理学等的理论渊源和丰富的国际、国内跨区域河流生态环境资源保护的实践经验。沿岸各国在公平分享跨界河流生态利益的同时，负有分摊跨界河流生态保护成本的义务。跨界河流生态受益者补偿原则应当通过一系列具体制度加以落实，包括基础调查制度、效益评估制度、成本分摊制度、受益补偿制度和权利救济制度     

跨界水资源公平合理利用原则的困境与对策

公平合理利用原则是国际水法的一项基本原则，它的内涵体现为权利义务的一致性，即各国有在其领土内利用跨界水资源的权利，同时又要承担不剥夺其他国家在其领土内利用跨界水资源的义务和不对跨界水资源进行损害和浪费的义务。从理论上看，对保护跨界水资源及协调跨界水资源利用冲突有重要的意义。但由于公平合理利用原则目前尚存在评价标准不明确、保障制度不完备等内在缺陷，以致其在实践中经常陷于难以适用的困境。要摆脱公平合理利用原则的适用困境，应以权利义务相一致的原理为指导，进一步明确“公平合理利用”的评价标准，厘清必要的用水优先权顺序，使公平合理利用原则具有可操作性。同时，应建立起受益补偿制度、公众参与制度、损害预警制度等有利于公平合理利用原则实现的保障制度。     

跨国水资源保护的法律措施——兼及中国的实践

国际流域各国在自己境内利用跨国水资源或进行其他活动时，有义务保护国际流域水资源，防止对其他流域国造成重大损害。对有关国际文件的规定和国际社会的实践进行了系统的分析和比较，从促进跨国水资源包括涉及我国的跨国水资源保护的目的出发，运用比较、概括和归纳的方法，对流域各国保护国际流域水资源的法律措施进行了归纳和总结。这些措施包括但不限于环境影响评价、交流信息、监测、通知、紧急情况下的援助、控制污染、公众参与等。最后就中国促进相关跨国水资源的保护提出了具体的措施建议：严格执行《环境影响评价法》、《水污染防治法》等法律法规；建立跨国河流水环境监测网；保持和加强与相邻国家和沿岸各国的信息交流与合作；继续与更多的沿岸国谈判和签署双边或多边流域保护协议，并建立流域保护或管理委员会负责对跨国河流流域的保护与管理.     

“一带一路”倡议下跨境流域生态补偿——国际经验与中国对策

跨境流域生态补偿机制的构建,是实现"一带一路"倡议目标的重要基础,有助于化解资源冲突、协调区域发展、增进利益协同,进而增强政治互信,加快经济融合,提升文化包容,推进命运共同体构建。本文基于对西方国家跨境流域生态补偿研究与实践的梳理,总结归纳出西方跨境流域生态补偿中强调流域生态系统分析、注重不同付费原则相互配搭、重视双/多边协商、建立多层次综合管理体系等经验。在此基础上,针对现阶段中国跨境流域生态补偿所面临的挑战,提出加强跨境协商合作平台建设、重视对跨境流域生态系统研究以及构建多层次协同管理体系等应对措施。     

跨国界河流、跨流域调水与我国南水北调的基本问题

跨国界河流常是当今国与国水资源矛盾与冲突的发源地。在水资源空间分布不均衡背景下,跨流域调水是解决地区性水资源短缺的有效途径之一;然而,它同时也导致一系列社会经济与资源环境等问题。本文论述了主要跨国界流域中有关国家围绕水资源展开的矛盾与冲突,谈判与妥协。     

Dynamic Cost-Effective Reduction Strategies for Acidification in Europe: An Application to Ireland and the United Kingdom

This paper describes the application of an optimisation model for calculating cost-effective abatement strategies for the reduction of acidification in Europe while taking into account the dynamic character of soil acidification in a number of countries. Environmental constraints are defined in terms of soil quality indicators, e.g., pH, base saturation or the aluminium ion concentration in the soil solution within an optimisation model for transboundary air pollution.We present a case study for Ireland and the United Kingdom. Our results indicate that reduction of sulphur dioxide emission is more cost-effective than that of nitrogen oxides or ammonia. The reduction percentages for sulphur dioxide are highest, for two reasons: (i) marginal sulphur dioxide reduction costs are relatively low compared to marginal reduction costs of nitrogen oxides and ammonia and (ii) sulphur dioxide reduction is more effective in reducing acidification in physical terms than nitrogen oxides or ammonia abatement. Our dynamic analysis shows that a (fast) improvement of soil quality requires high emission reduction levels. These reduction levels are often higher than reduction levels that are typically deduced from the static critical loads approach. Once soil quality targets are reached, in our model, less stringent emission reductions are required to maintain the soil quality at a constant and good target level. Static critical load approaches that ignore dynamic aspects therefore may underestimate the emission reductions needed to achieve predefined soil quality targets.     

Collaborative Science, Policy Development and Program Implementation in the Transboundary Georgia Basin/Puget Sound Ecosystem

The transboundary Georgia Basin Puget Sound ecosystem is situated in the southwest corner of British Columbia and northwest comer of Washington State. While bountiful and beautiful, this international region is facing significant threats to its marine and freshwater resources, air quality, habitats and species. These environmental challenges are compounded by rapid population growth and attendant uiban sprawl. As ecosystem stresses amplified and partnerships formed around possible solutions, it became increasingly clear that the shared sustainability challenges in the Georgia Basin and Puget Sound required shared solutions. Federal, state and provincial institutional arrangements were made between jurisdictions, which formalized small scale interest in transboundary management of this ecosystem. Formal agreements, however, can only do so much to further management of an ecosystem that spans international boarders. A transboundary regional research meeting, the 2003 GB/PS Research Conference, opened the doors for large-scale informal cross-boarder cooperation and management. In addition to cooperation, continued efforts to stem toxic pollution, contain urban growth, and protect and restore ecosystems, require a commitment from scientists, educators and policy makers to better integrate research and science with decision-making.Former Director of Planning and of Special Projects in the British Columbia Ministry of Municipal Affairs.
