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。     

When is increasing consumption of common property optimal? Sorting,congestion and entry in the commons

First-best pricing or assignment of property rights for rival and non-excludable goods is often infeasible. In a setting where the social planner cannot limit total use, we show that common-property resources can be over or under-consumed. This depends on whether the external benefits of reallocating users to less congested resources outweigh the additional costs imposed by new entrants. Importantly, we show that it may be optimal to encourage consumption of some common property resources. Our results have important implications for settings ranging from fisheries and forestry to recreational demand and transportation.     

结构红利与资源诅咒——西部大开发以来内蒙古产业结构变迁绩效评价

统计分析表明,西部大开发以来内蒙古经济存在越来越严重的就业-产值结构偏离趋势。采用shilt—share方法分别对西部大开以来内蒙古、西部和全国的劳动生产率进行分解和比较分析发现,内蒙古的结构红利不显著。因此,近年来内蒙古经济虽有良好的增长绩效,但其资源依赖型增长正通过价格机制和制度效率两个途径制约着产业结构的高级化与合理化变迁,即存在潜在的资源诅咒问题。     

System Dynamics to Sustainable Water Resources Management in the Eastern Snake Plain Aquifer Under Water Supply Uncertainty1

Abstract: Water supply uncertainty continues to threaten the reliability of regional water resources in the western United States. Climate variability and water dispute potentials induce water managers to develop proactive adaptive management strategies to mitigate future hydroclimate impacts. The Eastern Snake Plain Aquifer in the state of Idaho is also facing these challenges in the sense that population growth and economic development strongly depend on reliable water resources from underground storage. Drought and subsequent water conflict often drive scientific research and political agendas because water resources availability and aquifer management for a sustainable rural economy are of great interest. In this study, a system dynamics approach is applied to address dynamically complex problems with management of the aquifer and associated surface‐water and groundwater interactions. Recharge and discharge dynamics within the aquifer system are coded in an environmental modeling framework to identify long‐term behavior of aquifer responses to uncertain future hydrological variability. The research shows that the system dynamics approach is a promising modeling tool to develop sustainable water resources planning and management in a collaborative decision‐making framework and also to provide useful insights and alternative opportunities for operational management, policy support, and participatory strategic planning to mitigate future hydroclimate impacts in human dimensions.     

改造集散市场 建设新型再生资源回收利用体系

目前“三位一体”（回收网点→分拣中心→集散市场）回收体系模式,因集散市场功能单一、产业链短,不能带动行业走向产业化。回收网点建设适应我国国情,而集散市场成为先进的完整的回收体系的短板。按照示范基地建设标准,把集散市场改造升级为拥有深加工利用产业链,拥有平台支撑优势,能够进行资源的规模化高值化利用的产业园区。把回收和利用两大产业板块融合一体,是再生资源产业化的发展方向。     

地面浓度反推法计算石化企业无组织排放源强

对某石化企业储罐区和原油脱酸装置区的无组织排放非甲烷总烃进行监测,对监测数据进行Pearson相关分析,运用地面浓度反推法计算源强。实验结果表明：原油脱酸装置区各采样线浓度间的相关性好,反推出的源强较为准确,50,100,150 m采样线的反推源强非常接近,分别为21.68,21.60,19.76 t/a;而储罐区监测浓度的相关性不佳,该区域的非甲烷总烃无组织排放源可能不单一,不适用地面浓度反推法计算其源强。     

Testing The Pearl Hypothesis: Natural resources and trust

Do natural resources reduce social trust? This paper reviews the literature on natural resources and on trust. The existing theoretical and empirical literature suggests that natural resources can reduce trust through several indirect mechanisms. Notably, studies show that natural resources lead to institutional degradation, corruption, inequality, and civil war, all of which have been associated with reduced trust. In addition, game theoretical work on windfall gains suggests that there may be direct effect of natural resources on trust. This paper tests empirically whether there is a direct effect of natural resources on trust (The Pearl Hypothesis), using cross-country data. The results indicate that no such direct effect exists, but we find a significant effect on trust of intermediate variables affected by natural resources, such as institutions, corruption, inequality and/or civil war. Importantly, the relationship between corruption and trust turns out to be non-linear, indicating that the effect of natural resources on trust depends on the initial corruption level of a country. In highly corrupt societies, institutional improvements that reduce corruption may also undermine trust, which poses difficult challenges for anti-corruption policy.
