本文以印度经济增长模式为例,以竞争优势理论为分析框架,研究了跨工业化经济增长模式的内涵、生成机制与优劣势。研究表明,"基础设施薄弱、精英人才涌现"的资源禀赋结构、社会内部消费需求拉动、相关产业支撑、龙头企业带动、自由化的政策改革环境以及技术进步推动,促进了印度"跨工业化"经济增长模式的生成。基于此,通过中印两国经济增长模式的比较,指出"跨工业化"经济增长模式具有资源环境友好特征、能借助服务业的发展反向刺激工业发展等优势;并揭示了"跨工业化"增长模式的劣势,即难以提高就业率、服务业持续发展缺乏基础设施和制造业支撑等。鉴于我国服务业发展滞后,工业发展面临资源与环境高消耗的困境,我国应借鉴印度经验,培养服务业人才队伍、提高社会消费需求、优化服务业产业结构、培育服务业龙头企业、加快服务业自由化改革、提高服务业创新能力,以加快服务业的发展,增强服务业对工业的反哺效应,保障我国工业化进程在"资源与环境双约束下"又快又好地和谐推进。  相似文献

环境公益诉讼的理论基础探究   总被引:2,自引:0,他引:2  
环境不可能成为权利的对象,环境权论和公共信托理论都无法为环境公益诉讼提供理论支撑.多人利益意义上的环境公益诉讼以公民财产权、人身权等为根据,无须再虚构其他的理论根据.私人检察总长理论、私人实施法律理论是国家论、权力论,这种理论和我国法律中的公民检举权都以"积极公民"的存在为前提."积极公民"存在于个体与利益共同体关系中.国家、民族、自然环境决定的特定区域中的人的集合等都构成一个共同体.共同体成员对共同体的责任是公民担当"私人总检察长"、公益起诉人的理由.集体利益环境诉讼的理论基础是作为环境共同体成员的公民对共同的环境利益的责任.多人利益环境诉讼实际上是私益诉讼,只有集体公益的环境诉讼才是需要我们努力建设的环境公益诉讼.  相似文献

20世纪90年代开始,我国启动了公用事业市场化改革,民营资本特别是外资流向自来水供给、污水处理、城市生活垃圾收集与处理、燃气供应等行业。私人部门的介入激活了公共产品供给市场,有利于社会福利的增进,但也招致了诸多问题。公共产品供给民营化,并不意味着政府的完全退出,政府始终负有向社会公众提供公共产品或服务的原始责任,民营化只是在提供的形式上完成了向私人部门的转移,政府应完成从公共产品直接提供者向规制者的角色转换。本文以城市生活垃圾产业为例,进行了系统的分析。认为有效的规制应建立在真实的规制环境上,在城市生活垃圾产业民营化的规制中,面临着现有规制者与合约方一体、规制机构与企业信息不对称、政府部门承诺有限等规制约束。基于目前的规制环境,我国城市生活垃圾产业在推进民营化的同时,应建立起独立的规制机构,加强监管,逐步纵向一体民营化以降低交易成本,在合约中采用指数化价格分享企业租金。  相似文献

有效规制海底可燃冰开发伴生的多种类型生态环境风险,是保障可燃冰产业健康发展的内在需求。本文的主要目的即在中国现行法律体系规定的多元共治的环境法治理念和制度框架下,研究海底可燃冰开发环境风险多元共治的理论基础、现实必要性及其制度路径。文章主要运用类型化方法来梳理与归纳海底可燃冰开发引致环境风险的具体类型;运用理论分析与价值分析方法,论证海底可燃冰开发环境风险多元共治的必要性;运用法教义学分析、比较分析与系统分析方法,检视与剖析我国传统行政管制模式下的制度体系在规制海底可燃冰开发环境风险中的绩效与利弊,归纳与展开海底可燃冰开发环境风险多元共治的制度路径。本文的基本结论是,传统环境管制模式难以有效治理海底可燃冰开发引致的新型环境风险,当前我国所创新的环境多元共治模式,可以矫正政府单维管制海底可燃冰开发环境风险中的缺陷、弥补"监管之法"在规制海底可燃冰开发环境风险中的疏漏、克服单一行政命令方式在规制海底可燃冰开发环境风险中的困境,系统构建海底可燃冰开发环境风险多元治理体系。在完善行政监管和推进私人治理两个层面对海底可燃冰开发环境风险多元共治的基础上提出具体建议。在完善行政监管层面,我国《环境保护法》《海洋环境保护法》等法律规范经过拓展解释适用,仍然因为规制路径的间接性、零散性而产生内生弊端,亟待专门立法;在推进私人治理层面,多元共治机制分为多元主体参与机制与诉讼机制,应重视通过鼓励环保公益组织、可燃冰行业协会与私人等多元主体采取多元参与和私益诉讼方式,以发挥其在规制海底可燃冰开发环境风险中的综合效用。  相似文献

在经济服务化与低碳化的双重背景下,研究中国服务业碳生产率的演变轨迹,区域差异及空间收敛特征,对于推动中国服务业高质量发展具有重要的意义。采用2004—2016年中国30个省(区、市)的面板数据,对服务业碳生产率进行测度,并对其演变轨迹与区域差异进行分析,在此基础上,系统考察中国服务业碳生产率的空间收敛性。研究表明:①中国服务业碳生产率在整体上呈逐年增长态势,且呈现从东到西逐次递减的格局。②中国服务业碳生产率存在正向空间自相关关系,并且空间自相关程度表现出波动上升趋势。③全国与西部服务业碳生产率均不存在σ收敛,即服务业碳生产率的地区差异并未随着时间的推移而缩小;东、中部服务业碳生产率则在整体上呈现σ收敛特征。全国以及东、中、西部服务业碳生产率均存在绝对β收敛和条件β收敛,即服务业碳生产率落后地区对发达地区存在"追赶效应",各地区服务业碳生产率最终向自身的稳态水平趋同;空间效应加快了全国与东部服务业碳生产率的β收敛速度。④人均服务业增加值增长速度、部门结构以及能源消费结构对服务业碳生产率具有显著的负向效应,人力资本则对服务业碳生产率产生了显著的正向影响。据此,本文的政策启示如下:①重视服务业碳排放问题,构建服务业低碳绩效评估体系。②探索建立定期会商制度,加强服务业低碳技术的跨区域交流合作。③完善基础设施,促进要素空间互动和优化重组。④调整服务业能源结构与部门结构,推进人力资本积累和服务业稳增长。  相似文献

Integration of indigenous knowledge and ethnoscientific approaches into contemporary frameworks for conservation and sustainable management of natural resources will become increasingly important in policies on an international and national level, both in countries that are industrialised and those that have a developing status. We set the scene on how this can be done by exploring the key conditions and dimensions of a dialogue between ȁ8ontologiesȁ9 and the roles, which ethnosciences could play in this process. First, the roles of ethnosciences in the context of sustainable development were analysed, placing emphasis on the implications arising when western sciences aspire to relate to indigenous forms of␣knowledge. Secondly, the contributions of ethnosciences to such an ȁ8inter- ontological dialogueȁ9 were explored, based on an ethnoecological study of the encounter of sciences and indigenous knowledge in the Andes of Bolivia, and reviewed experiences from mangrove systems in Kenya, India and Sri Lanka, and from case-studies in other ecosystems world-wide, incl. Australia, Burkina Faso, Ecuador, Ethiopia, Guatemala, Indonesia, Nepal, Niger, Philippines, Senegal, South-Africa and Tanzania.  相似文献

We review studies of the effects of low ambient ozone concentrations on morbidity that found a negative coefficient for ozone concentration. We call this a Paradoxical Ozone Association (POA). All studies were in regions with methyl ether in gasoline. All but one study carefully controlled for the effects of other criterion pollutants, so the phenomenon cannot be attributed to them. One was in southern California in mid-summer when ozone levels are highest. Because ozone is created by sunlight, the most plausible explanation for a POA would be an ambient pollutant that is rapidly destroyed by sunlight, such as methyl nitrite (MN). A previously published model of engine exhaust chemistry suggested methyl ether in the fuel will create MN in the exhaust. MN is known to be highly toxic, and closely related alkyl nitrites are known to induce respiratory sensitivity in humans. Support for the interpretation comes from many studies, including three linking asthma symptoms to methyl tertiary butyl ether (MTBE) and the observation that a POA has not been seen in regions without ether in gasoline. We also note that studies in southern California show a historical trend from more significant to less significant ozone-health associations. The timing of those changes is consistent with the known timing of the introduction of gasoline oxygenated with MTBE in that region.  相似文献

The use of quantitative data for constructing prognostic maps of the dynamics of ecosystem degradation and restoration by nonlinear simulation methods is a topical field of landscape ecology. This method of dynamic cartography is based on fiberwise comparison of data on the state of Chernye Zemli (the Kalmyk Republic, Russia) in different years and the detailed analysis of the period on which the prognosis was based. For this purpose, materials of repeated aerial and satellite photography obtained during a long period (1954–1993) were used. Comparison of maps characterizing the dynamics of Chernye Zemli between 1958 and 1993 allows prognostic electronic maps for the next 10–15 years (with a five-year interval) to be drawn and land prognosis for the next 20–30 years (1998–2023) to be obtained.

Information regarding the distribution of volatile organic compound (VOC) concentrations and exposures is scarce, and there have been few, if any, studies using population-based samples from which representative estimates can be derived. This study characterizes distributions of personal exposures to ten different VOCs in the U.S. measured in the 1999-2000 National Health and Nutrition Examination Survey (NHANES). Personal VOC exposures were collected for 669 individuals over 2-3 days, and measurements were weighted to derive national-level statistics. Four common exposure sources were identified using factor analyses: gasoline vapor and vehicle exhaust, methyl tert-butyl ether (MBTE) as a gasoline additive, tap water disinfection products, and household cleaning products. Benzene, toluene, ethyl benzene, xylenes chloroform, and tetrachloroethene were fit to log-normal distributions with reasonably good agreement to observations. 1,4-Dichlorobenzene and trichloroethene were fit to Pareto distributions, and MTBE to Weibull distribution, but agreement was poor. However, distributions that attempt to match all of the VOC exposure data can lead to incorrect conclusions regarding the level and frequency of the higher exposures. Maximum Gumbel distributions gave generally good fits to extrema, however, they could not fully represent the highest exposures of the NHANES measurements. The analysis suggests that complete models for the distribution of VOC exposures require an approach that combines standard and extreme value distributions, and that carefully identifies outliers. This is the first study to provide national-level and representative statistics regarding the VOC exposures, and its results have important implications for risk assessment and probabilistic analyses.  相似文献

Variation in the reproduction of Varroa jacobsoni mite was studied in relation to the expansion of the range of its parasitism on the honeybee. Geographic differences in the seasonal dynamics of mite reproduction in the nests of bee families were revealed. Variation in the sex ratio of mites and the factors inhibiting their reproduction at the northern boundary of the honeybee range are considered. The forms of parthenogenetic reproduction in V. jacobsoni are discussed.  相似文献

The Eastern Mediterranean region is among the regions which were predicted to become drier under IPCC climate scenarios. Here, we document a gradual reduction of rainfall and tree growth and the loss of rural springs during the last decades of the twentieth century. Years with severe drought are associated with very low tree growth (dendrochronology) and dry falling of springs as evidenced by interviews with local stakeholders. The paper discusses the consequences of accelerating drought on natural vegetation and agriculture and points at the interaction with fire dynamics and economy, both likely to enhance the drought effect.  相似文献

The effect of long-term exposure to natural excretions of the European polecat on the morphological parameters and hormonal status of adult male Campbell hamsters (Phodopus campbelli) and dwarf hamsters (Ph. sungorus) was studied. Exposure to volatile components of natural excreta of a potential predator did not have any significant effect on hamsters. The combined influence of volatile and nonvolatile components of the polecat’s excretions caused physiological stress in Ph. campbelli, while in Ph. sungorus, on the contrary, an increase in thymus weight and the plasma testosterone level was recorded.  相似文献

The use of experimental settings to observe human behaviour in a controlled environment of incentives, rules and institutions, has been widely used by the behavioural sciences for sometime now, particularly by psychology and economics. In most cases the subjects are college students recruited for one to two hour decision making exercises in which, depending on their choices, they earn cash averaging US$ 20. In such exercises players face a set of feasible actions, rules and incentives (payoffs) involving different forms of social exchange with other people, and that in most cases involve some kind of externalities with incomplete contracts, such as in the case of common-pool resources situations. Depending on the ecological and institutional settings, the resource users face a set of feasible levels of extraction, a set of rules regarding the control or monitoring of individual use, and sometimes ways of imposing material or non-material costs or rewards to those breaking or following the rules. We brought the experimental lab to the field and invited about two hundred users of natural resources in three Colombian rural villages to participate in such decision making exercises and through these and other research instruments we learned about the ways they solve - or fail to - tragedies of the commons with different social institutions. Further, bringing the lab to the field allowed us to explore some of the limitations of existing models about human behaviour and its consequences for designing policies for conserving ecosystems and improving social welfare.  相似文献

The size of shells in some freshwater pulmonate mollusk species abundant in Western Siberia (Lymnaea fragilis, L. terebra, Planorbis planorbis, and Anisus leucostoma) is relatively large in the south and decreases in the north. It is supposed that this phenomenon is explained by the fact that the season with conditions allowing the growth of mollusks is shorter in the north than in the south of Western Siberia.  相似文献
