Post-Fordist transformation,the sustainability concept and social relations with nature: a case study of the Hamburg region

Following the United Nations Conference on Environment and Development, the concept of sustainability in general and of urban sustainability in particular has become increasingly significant in the course of the 1990s. Even if the environmental problems of cities are far from being solved, one can interpret this development as a change in the relationship between society and nature on both a discursive and a material level. At the same time the transition from Fordism to post-Fordism has given rise to new forms of urban entrepreneurialism, with an absolute priority to economic competitiveness on the one hand and sharpened social conflicts on the other. Looking at the case of the Hamburg region, the article discusses the interaction of these processes. Contrary to the understanding of sustainability as a broadly accepted policy goal it conceptualizes sustainability as a terrain of conflict. As such, we will argue, the sustainability concept and the underlying change in social relations with nature contribute to containing the contradictions of capitalist societalization, which in the transition to post-Fordism have become more visible again.

环境规制会影响产业集中度吗?:一个经验研究

作为刻画产业结构的重要指标之一——产业集中度,一直受到国内外学者的广泛重视,但鲜见有学者研究环境规制会对产业集中度带来何种影响。为了对此进行研究,本文以我国工业部门1996-2006年的数据为样本,首先计算出产业集中度(CR4和CR8)水平,并运用面板数据分析方法,在控制相关变量的基础上,研究了环境规制对产业集中度带来的影响,得到以下结论:(1)在不考虑其他控制变量时,环境规制变量对产业集中度产生不显著的正向促进作用,但随着控制变量的逐步引入,环境规制变量的显著性水平逐步提高,模型总体拟合效果趋于优化;(2)同时,进入退出壁垒、利润率水平、经济干预政策和规模经济程度四个控制变量也会对产业集中度产生显著的正向推动作用。因此,适度强化环境规制水平,不仅有利于保护环境,优化资源配置,淘汰落后产能,解决结构性产能过剩,而且有利于提升产业集中度,增强我国企业在国际上的竞争力。     

The use of best management practices to respond to externalities from developing shale gas resources

The public is concerned that activities accompanying hydraulic fracturing in the development of shale gas resources are unnecessarily adversely affecting them and the environment and is petitioning elected representatives to take actions to reduce risks. The health risks associated with fracturing chemicals and air pollutants are relatively unknown and constitute the impetus for public concern. An evaluation of state legal and regulatory provisions regarding best management practices discloses that states are not adopting timely regulations to protect people and the environment from activities accompanying hydraulic fracturing. Simultaneously, regulatory policy concerning negative externalities suggests that governments underinvest in the protection of human health and environmental quality. Governments have choices in protecting people from dangers that accompany shale gas development. Due to the risks of injuries and unpaid damages from shale gas development, governmental policies need to evolve to accord people greater health protection.     

不同类型环境规制对企业技术创新影响比较研究

波特假说提出后,引发了大量关于环境规制对企业技术创新影响的实证研究,但是少有文献提及不同类型环境规制对企业技术创新的影响,且较少涉及环境规制对企业技术创新的非线性作用。本文基于费用型环境规制与投资型环境规制两种类型,利用我国30个省份在2003-2012年间的面板数据,实证研究了不同类型环境规制对企业技术创新的影响。研究结果表明,费用型环境规制对企业技术创新产生了显著的"挤出效应",排污费的征收增加了企业的生产成本,但是并不能促进企业进行技术创新;投资型环境规制总体上对企业技术创新产生了"激励效应",这在一定程度上支持了"波特假说"。投资型环境规制通过降低企业技术创新的风险,增强企业的信心和预期水平,提升了企业的竞争力。在三类环境投资中,城市环境基础设施建设投资对企业技术创新的促进作用最为显著;建设项目"三同时"环保投资对技术创新的正向作用难以确定;而工业污染源治理投资则在一定程度上抑制了企业的技术创新。门限回归分析表明,费用型环境规制与投资型环境规制均存在门限效应,即环境规制程度的不同,对技术创新的影响也有所差异。因此,在制定环境规制政策时,要考虑不同环境规制政策的效果差异,有所侧重地制定和实施环境规制政策。     

基于央地分权视角的环境规制策略演化博弈分析

当前,我国环境的根本问题是由粗放式的经济发展模式所引起的,而这一发展模式的根源在于"中国式央地分权"下的政府行为。这种具有中国特色的分权模式的独特之处在于中央政府对地方经济放权的同时,仍然保持政治上的集权控制,上级政府根据绩效考核提拔地方官员,即"经济分权、政治集权"特性。中国式分权下,我国的环境治理体制依据行政区域的划分来设置管理权限,按照政府层级的构成进行垂直式领导,即中央政府统一制定环境政策,地方政府负责各辖区内环境政策的执行。在全国范围内,央地两级政府的关系表现为动态的重复博弈。针对我国现行环境规制执行策略,借助演化经济学研究工具,基于央地分权的视角,将地方政府与中央政府两大主体同时纳入分析框架。根据复制动态方程探讨参与主体的行为演化特征和行为演化稳定策略,在模型求解的基础上,利用MATLAB仿真工具,分析不同情形下参与主体演化稳定策略的走向及其收敛趋势。研究发现,央地两级政府在环境规制策略执行过程中的动态演化,很大程度上取决于地方政府环境规制执行力度、成本、收益和损失以及中央政府监管力度、成本和处罚力度等因素的大小。因此,针对地方政府环境策略激励设计,应重点改革政绩考核机制,引入市场机制,并通过环保补贴、财政转移支付等手段降低地方政府环境规制执行成本;中央政府应通过调节政绩考核体系中的经济发展指标和环境指标的权重系数来加强对地方政府环境规制执行情况的监管力度,建立第三方监管机制以降低中央政府监管成本,制定合理的奖惩机制以提高监管效率;以期推动我国环境规制策略的高效执行,促进环境绩效向经济绩效的良性转换,实现双重帕累托改进。     

中国天然气价格管制的碳排放及经济影响——基于非完全竞争CGE模型的模拟研究

中国天然气产业的最大特点是垄断程度较强,政府对天然气产业的各个环节均存在价格管制。鉴于此,本文通过构建CGE模型以期全面量化分析政府对天然气产业价格管制政策变动产生的影响,从而为政府制定决策提供可供借鉴的依据。与以往的研究不同,本文构建的静态CGE模型,不仅刻画了天然气产业非完全竞争的市场结构还刻画了政府对天然气产业的价格管制行为。运用该模型,本文分别从消费侧以及供应侧的角度模拟了政府对天然气产业价格管制政策变动对我国碳排放及经济的影响,并且从经济结构以及能源消费结构的角度进一步分析了天然气价格管制政策变动的二氧化碳排放机制。模拟结果表明:1消费侧价格管制。提高天然气价格能够通过产业结构调整以及能源消费结构调整降低经济主体对天然气的消费进而降低二氧化碳的排放,同时由于天然气市场规模的缩小导致天然气产业的超额利润率有所下降。提高天然气价格提高了居民消费价格指数(CPI),降低了实际GDP以及居民福利水平。降低天然气价格对二氧化碳排放的影响、传导机制以及经济影响与提高天然气价格产生的影响类似,但是作用效果基本上相反。2供应侧价格管制。取消天然气供应侧价格管制能够通过优化要素配置促进实际GDP的增长、居民福利水平的改善并且降低居民消费价格指数(CPI),在收入效应的作用下不仅提高了经济主体对天然气的消费还提高了对能源总量的消费,从而增加了二氧化碳排放,同时由于天然气市场规模的扩大促进了天然气产业超额利润率的增长。因此,应该逐渐建立完善的天然气价格管理体制,确保天然气资源的有效利用;对天然气产业超额利润率进行管控,避免产生较大的负面收入分配效应;逐步取消天然气供应侧的价格管制,打破行政垄断,引入市场竞争机制,推动天然气产业的市场化进程。     

Remedies for loss and damage caused by climate change from the dimension of climate justice

Adverse consequences to the ecological system and human health caused by impacts potentially attributable to climate change have already drawn great and widespread concern of many scientists and international organizations. However, we still have a hard time determining exactly the impact of climate change on the environment or the damage that climate change inflicts on countries comprising small islands or low-lying lands in light of today’s science and technology. The progress for dealing with the issue of loss and damage has been struggling for a long time from the beginning to the present. In this paper, the author begins by summarizing talks on the concept and the positions of commentators. The author is proposing that the development of future climate negotiations and rule-making process be based on global climate justice as a standard for measuring value. Also, the author proposes that a holistic view of climate justice be established. Generally, three aspects of climate justice can be derived. First, the dimension of human rights protection shows that protection of fundamental human rights is a logical precondition if small-island and low-lying countries are able to achieve climate justice. Second, the definite and traditional concepts of distributive justice and corrective justice hold the view that the principle of common but differentiated responsibilities should be upheld as a basic standard of allocating rights and duties associated with climate change. Third, climate justice requires that any state follow the “no-harm principle,” which is regarded as an international customary rule. According to the principle, the obligation of states to prevent the use of their territory for causing trans-boundary harm to the environment shall be a violation of state responsibility, which incurs international punishment. Then we put forward three remedial approaches in light of climate justice, including the approach of State Responsibility (SR) based on the principles and rules of international human rights law and international environmental law. Based on clear rules, the judge can determine whether the damaging behavior or the damage perpetrated by a state party constitutes a state responsibility. The International Environmental Regulation (IEB), which means solving the problems within the framework established by the Conventions on Climate Change, takes advantage of the market mechanisms and incentives such as fund and insurance support system to relieve or compensate the loss and damage. International Environmental Dispute Settlement Mechanism (IEDSM), which includes the means such as consultations, negotiations, nonmandatory ways and international arbitration, international judicial ways to solve these disputes, functions as a procedural safeguard. As an active promoter of global climate governance, China should no doubt stand by the principle of Common But Differentiated Responsibility (CBDR) and take it as a basis for negotiations, actively strengthen the work of South-South cooperation, fulfill her international climate commitments without reservation, vigorously develop a low-carbon economy, and actively promote international negotiations on the subject of loss and damage.     

环境规制是否抑制了国际R&D溢出效应——以长江经济带为例

环境规制与技术进步转变方向的非一致性近年来受到较多关注,但学者们普遍忽视了开放经济条件下二者的关系。本文以1999~2013年长江经济带11个省市为研究样本,实证检验了环境规制对国际RD溢出效应的影响效果。研究表明:(1)环境规制强度和国际RD溢出水平呈现U型关系,即在长江经济带各省市,初始比较弱的环境规制强度抑制了国际技术溢出,但是随着环境规制强度的增加,国际RD溢出水平不断上升;(2)采用不同的环境规制方式会影响国际RD溢出和环境规制的U型关系,改变环境规制水平的拐点;(3)目前长江经济带各省市环境规制水平比较低,大多处于U型左侧。最后本文依据上述结论提出了相应的政策建议。
