在经济高速增长的同时,环境保护与经济发展二者之间相互促进、相互制约,相互矛盾而又相互统一。在资源有限的前提下,如何达到经济发展与环境保护和谐的模式,本文通过分析西部开发对自然环境及经济环境的影响以及环境的改变对经济环境所产生的影响,得出经济发展与环境呈正相关的因果关系,通过对目前经济开发与环保之间现有模式的分析,构建了经济与环境并重和谐发展的模型。 相似文献

如何建设节约型社会是时下舆论讨论的热点问题之一,正确处理好经济发展与环境保护也是建设和谐社会的核心命题之一。本文通过分析晋江市工业垃圾治理模式如何由靠牺牲环境为代价的粗放型模式—模式Ⅰ,向封闭的、可循环的集约型模式—模式Ⅱ转变,证明经济发展与环境保护是完全可以协调统一的;同时,通过分析模式Ⅱ的不足,进一步引入排污权交易理论,结合晋江市的实际情况,创造性地提出了具有实用性和通用性的垃圾治理方式——模式Ⅲ。 相似文献

Through Joint Implementationand the Clean Development Mechanism, reductionsof greenhouse gas emissions achieved abroad canbe credited to domestic firms. However, thetechnical, economic and political risksinvolved may prevent the private sector frominvesting in such projects. This paperdescribes three types of risks which emissionreduction projects are exposed to. Eleven pilotprojects carried out under the ActivitiesImplemented Jointly (AIJ) program and financedby Sweden are evaluated. Actual project costsare found to exceed projected costs in allcases. Annual emission reductions also deviatefrom their expected values and vary stronglyover time, supporting the hypothesis that suchprojects are risky business. The riskmanagement tool portfolio diversification isapplied to a sample of Swedish AIJ projects.The results indicate that diversification canreduce the risks of greenhouse gas mitigationprojects significantly. Thus, carbon funds area promising way of lowering the risks of theKyoto Mechanisms for private sector investors. 相似文献

This paper investigates the link between trade and environment by exploring the effects of green tariffs on innovation, location of production and the environment. It shows that tariffs levied on polluting goods could result in less world pollution than global harmonization of environmental standards by inducing more pollution-abatement R&D effort and generating lower unit emissions from production. Specifically, green tariffs reduce pollution by (1) shifting production to the region where environmental standards are respected, (2) inducing the firm in the clean country to engage in more abatement R&D by granting it a higher market power/share in its home market, (3) instigating green R&D investment by deterring delocation. When these outweigh the R&D-creating effect of environmental harmonization in the dirty country, green tariffs bring about a cleaner environment. 相似文献

从制造业的角度出发,分析了政府对环境管制(ER)的两种形式:正式管制(FER)和非正式管制(I-ER),建立了环境管制均衡方程,并且采用面板数据的分析方法对理论假设进行了验证。研究表明,假设的影响制造业环境管制的主要因素:政府保护意愿、劳动密集程度、产业规模、经济外向度、产业国有化程度、科技吸收转化支出和劳动力素质的高低均产生了显著的影响。 相似文献

Speeding up the environmental protection and construction is one of the major issues in "Greener Olympic Games" held in Beijing in 2008. Making a thorough study to find out the reliable measures to ecological resumption in Beijing has an important scientific and practical significance. It can provide scientific basis for making a better decision for "Greener Olympic Games" held in capital Beijing and development in harmony for society and economy, as well as management for ecological environment. By studying of change of ecological footprint from 1990 to 2003 in Beijing, the paper shows that ecological footprint per capita has a strong relativity with population and GDP, and both of the correlation coefficient between them is about 0.92, as well as the fossil energy land has a position in the lead in ecological footprint items. The study also shows that the ecological capacity per capita in Beijing occupied about 1.25% in global ecological capacity per capita. Began 1990, the ecological deficit in Beijing was about 0.72 hm2, which is at strong unsustainable development at present. Finally, the paper suggests social and economic structure should be adjusted as soon as possible, resources should be strengthen sustainable used and population increasing should be controlled strictly, as well as arable land also should be under control used for built-up areas. Simultaneity, the utilizing ratio of energy sources should be increased, and the consumption of energy sources and ecological deficit in Beijing should be reduced in order to speed up the society and economy development in harmony and sustainment. 相似文献

This paper continues a line of research begun in Batabyal (1995a). I model the interaction between a regulator and a monopolistic, polluting firm as a Stackelberg differential game in which the regulator leads. The firm creates pollution, which results in a stock externality. I analyze the intertemporal effects of alternate pollution control measures. The principal issue here concerns the dynamic inconsistency of the optimal solution. Inter alia, I compare the steady state levels of pollution under optimal and under dynamically consistent policies. 相似文献
