WTO“稀土案”与中国自然资源出口管制的完善

举世瞩目的 WTO"稀土案"于2014年8月7日终落帷幕。同先前的"原料案"一样,中国还是难逃败诉的命运。上诉机构支持申诉方的大部分指控,再次否决了《1994年关税与贸易总协定》(General Agreement on Tariffs and Trade of 1994,以下简称GATT)第20条对中国《入世议定书》的可适用性,从而确认中国对稀土、钨、钼三种原材料采取的出口税及配额等管制措施违背了WTO相关规则和入世所作的特殊承诺。作为自然资源的进出口大国,在自然资源贸易纠纷(特别是出口管制问题)不断"升温"和WTO争端解决机制运用愈来愈频繁的今天,中国应认真总结和反思这场"稀土保卫战"失利带来的经验教训,以从源头上破解中国出口管制措施在WTO体制下遭遇的法律困境,避免今后类似案件败诉的重现。基于此,本文综合应用案例分析、文本分析、历史分析和比较分析等方法对"稀土案"争讼的焦点和争端解决机构(DSB)的裁决意见做了详尽的透析,结果发现此案中DSB的审理不同程度存在着解释僵化、无视中国缔约真意及主观随意、前后矛盾等失范之处,对中国颇为不公。不过,该案也从另外一方面暴露出中国出口管制立法的疏漏与实施缺陷。是故,本文建议中国:1请求部长级会议/总理事会对GATT与《入世议定书》关系做出统一解释,并单独将出口税承诺纳入减让表;2重视DSB既有的裁决思路,根据WTO规则修改相关出口管制法规;3加强资源开采的法律管控,提高资源税的征收标准;4确保对内外资源需求企业的管制一致,优化出口许可管理,努力从WTO法和国内法两个层面推动现行自然资源出口秩序的完善,使中国今后对自然资源的出口管制既能符合WTO规则又能达致确保本国经济可持续性发展之目的。     

中国区域能源、经济与环境耦合的动态演化

文章全面解析了系统耦合机制,以此为基础构建了能源、经济与环境三系统耦合模型,测算了1995—2014年中国四大区域三大系统间的耦合协调水平,并从时空两个维度对区域三系统交互关系的变化特征以及差异做出了全面讨论。结果表明,1各省区经济和环境综合指数呈持续上升的良好态势,而能源综合指数在小幅波动中保持了较为稳定的发展状态,同时三者关系极为密切,具体表现为三类指数的变动具有显著的相关性。2三系统交互作用的耦合度均保持不断递增的演化趋势,但绝对水平较低,且区域间差异较为明显,整体上呈现由东到西递减态势。3三系统的耦合变化与能源-经济、能源-环境和经济-环境三类二元系统的协调发展具有密切的相关性。4在探索三系统耦合协调的持续发展路径时,需重点引导三系统打破固有束缚,通过有秩序的相互配合产生单个系统所不具备的发展能力。而从现实状态看,在当前面临经济下行、资源环境不可持续以及区域发展差异扩大等问题的严峻挑战,各省区需结合本区域实际发展状况和比较优势制定发展规划。东部需以雄厚的经济实力为基础强化技术创新,以带动能源高效利用和环境保护;中部和东北需调整能源消费结构并提高能源利用效率;西部则应将重点放在绿色发展和防范环境风险两方面。     

The 2030 Agenda for Sustainable Development and China’s implementation

The concept of sustainable development has experienced great development and change at different levels of theoretical connotation and practical implementation since 1960s and 1970s when it was first proposed. People’s understanding of the relationship between economy, society, and environment has been continuously deepened over the years. When it came to the end of 2015, it is necessary to examine the results of the United Nations Millennium Development Goals on sustainable development, and at the same time, the post-2015 framework and guidance on sustainable development at the global level were to be made, including the ideas, action plans, key areas that would guide the global sustainable development. The 2030 Agenda for Sustainable Development has developed a 5P theoretical framework of being people-centered, global environmental security, sustained economic prosperity, social justice and harmony and partnership promotion, including a political declaration, 17 overarching goals and 169 specific targets, specific ways of implementation, as well as the follow-up. It is the road map to achieve global sustainable development and meet the requirements of the millennium development goals. This paper summarizes the understanding of the concept of sustainable development from its origin, its significant development, to the proposition and development of the 2030 Agenda for Sustainable Development, and its strategic impact on China.     

山东半岛城市群人居环境质量综合评价

随着中国城市化的高速发展,"城市病"问题日益突出,城市群作为统筹区域协调发展、建设宜居人居环境的重点地区,其人居环境发展状况备受关注。基于此,本文以山东半岛城市群为例,从人文环境、经济环境、社会环境和生态环境4个方面构建人居环境质量综合评价指标体系,利用人居环境质量计算模型和系统协调度模型,对其人居环境质量进行静态定量化评价和动态综合性评价。研究表明:(1)山东半岛城市群人居环境质量与社会环境的关联性最大,经济实力、基础设施水平时空发展不均衡、地域差异大,是制约山东半岛城市群人居环境发展的突出问题。(2)2000—2014年山东半岛城市群人居环境综合水平呈现良好的上升趋势,且增速较稳,增幅较小;各要素间的协调性均达到了中级协调等级;系统层的评价值除人文环境外,均呈现不同程度的波动式上升态势;领域层的评价值差异明显,发展不均衡。(3)城市群内部各城市人居环境综合质量水平逐步提高,且排名相对稳定;各要素间的协调度等级差异较小,但起伏变化较大;人居环境质量时空分异特征明显,呈现东西高、中间低的格局,内部级别差异显著,可分为较好、一般、较差、差4个等级。在今后的发展中,应针对山东半岛不同城市人居环境问题采取因时因地制宜的协调对策,创造整体最优人居环境。不仅要提高城市群的整体经济水平,提升城市群的短板建设,推动人居环境协调发展,还要符合新常态下城市发展与建设的要求,加快山东半岛城市群的区域创新体系构建,科学引领产业转型升级,优化产业结构,加强山东半岛城市规划研究与实施力度,探索"多规合一"模式。     

Measurement of public awareness of climate change in China: based on a national survey with 4,025 samples

Just before the new round of UN climate change conference in Bonn, a survey report, named as the Climate Change in the Chinese Mind 2017, was released in Beijing. The investigation was conducted in the form of a computer-assisted telephone survey with a sample size of 4,025 samples, covering 332 prefecture-level administrative units and four municipalities in China. Urban-rural proportion and sex proportion were specially taken into account, so as to demonstrate the Chinese public awareness objectively. The investigation measures the public awareness from six aspects, which includes climate change beliefs, impacts, response, policies, actions, and the assessment of the effectiveness of climate communication. This article presents the key findings of the survey and provides further insights behind the data.     

长江中游城市群经济-城市-社会-环境耦合度空间差异分析

以长江中游城市群的36个城市为例,构建了经济发展、城市化、社会保障、生态环境综合评价指标体系,运用耦合度模型评估了36个城市2011~2013年的耦合度,并利用GIS技术分析系统的得分与耦合度的空间分布特征。结果表明:长江中游城市群的36个城市的经济发展、城市化和社会保障水平的空间分布比较相似,三者间存在显著的正相关关系。但是,存在显著性的地区差异。36个城市生态环境得分均值很高,城市之间差异很小。从耦合度的空间分布来看,长江中游城市群明显存在3个高耦合度的聚集区域,即长株潭城市圈,武汉-南昌(含鄂州、黄石和九江)城市带和鄂北4市,即十堰、襄阳、宜昌和荆门。最后,36个城市之间耦合度的差异呈现逐年缩小的趋势。     

全球升温1.5℃与2.0℃情景下长江中下游地区极端降水的变化特征

基于长江中下游地区1961~2100年区域气候模式COSMO-CLM(CCLM)模拟与1961~2005年气象站观测的逐日降水数据,通过统计计算年降水量、强降水量、暴雨日数和极端降水贡献率4个极端降水指数,研究全球升温1.5℃与2.0℃情景下,长江中下游地区极端降水的时空变化特征。结果表明:(1)全球升温1.5℃情景下,年降水量相对于1986~2005年减少5%,强降水量、暴雨日数和极端降水贡献率分别增加7%、33%和4%;概率密度曲线表明,年降水量均值下降,强降水量、暴雨日数和极端降水贡献率均值上升,极端降水方差增大;年降水量、强降水量和暴雨日数在空间上表现为南部增加北部减少,极端降水贡献率则相反。(2)全球升温2.0℃情景下,年降水量下降3%,强降水量、暴雨日数和极端降水贡献率分别上升15%、46%和15%;年降水量均值稍有减少且方差稍有上升,强降水量、暴雨日数和极端降水贡献率均值和方差明显增加;年降水量减少区域位于长江主干以北,强降水量、暴雨日数和极端降水贡献率表现为绝大部分地区增加的空间变化特征。(3)全球升温由1.5℃至2.0℃时,年降水量、强降水量、暴雨日数和极端降水贡献率分别增加3%、7%、10%和11%;随升温幅度的增加极端降水均值和方差上升;极端降水呈增加态势的范围扩大。因此,努力将升温控制在1.5℃对降低极端降水的影响具有重要意义。     

Best Practices in Environmental Communication: A Case Study of Louisiana's Coastal Crisis

This mixed-method case study of environmental communication best practices in Louisiana, USA, identifies trends and approaches as informed by environmental psychology. The results provide key insights for environmental communicators, especially communicators in coastal regions. In-depth interviews with both environmental psychologists and environmental communicators showed that both groups emphasized knowing the audience, telling local stories, building relationships with target audiences and targeted messaging. Both psychologists and communicators also frequently mentioned general messaging concerns of source credibility, avoiding controversial terms and talking about issues, impacts and solutions to which the target audience can relate. A representative survey revealed that Louisiana residents are most interested in hearing about how environmental issues such as climate change, coastal land loss and flooding are affecting their own communities. This finding supports the idea that environmental communicators could do a better job tapping into strong place attachment and sense of community among coastal residents to promote action.
