在我国实施自愿协议式工业环境管理的可行性探讨

本文扼要综述了自愿协议式环境管理的发展、特点及其成因,并且简要介绍了这种新的环境管理方式在欧盟国家的应用情况。该管理方法在欧盟国家的成功,证明它是一个非常有效的环境管理方法,这种方式对解决政府“命令式”管理失灵起到十分有益的补充作用。在我国实施自愿协议式工业环境管理机遇大于风险,学习、改造并引进自愿协议式工业环境管理方法,可以提高我国工业环境管理水平,为实施可持续发展战略服务。     

Commodity booms and their impacts on the Western Australian economy: The iron ore case

Western Australia is a resource-rich province. Since the 1890s, resources booms have played a key role in the development of the state's economy. In the last few years, Western Australia's resources industry has continued to enjoy exceptional conditions created by strong international demand for commodities. This paper aims to examine the likely impact of this commodity boom in the iron ore sector on the Western Australian economy, using a general equilibrium approach. The modeling results indicate that the Western Australian economy will benefit from the expansion in iron ore exports and investment in terms of rising consumption and employment, although at the industry level there will be losers as well as winners.     

A mineral commodity life-cycle?: Relationships between production,price and economic resources

The production, price and economic resources profiles of a number of mineral commodities are examined and consideration is given to the theory that such profiles can be related to one another within the framework of a life-cycle model of development. While the behaviour of some of the commodities examined appears to lend support to the theory, that of others reveals fundamental problems with its underlying assumptions. It is concluded that, while the demand for a mineral commodity in specific uses may indeed manifest cyclical tendencies, as a general behavioural theory and as a basis for resource estimation the life-cycle model applied to minerals is of little value.

International environmental agreements with consistent conjectures

We introduce consistent conjectures into Barrett (1994) canonical model of international environmental agreements. The existing literature assumes inconsistent Nash conjectures, despite the fact that policymakers recognize that abatement levels are strategic substitutes and increases in abatement generate carbon leakage. With consistent conjectures much of the conventional wisdom is reversed. The non-cooperative abatement level is below the Nash equilibrium. The difference between Nash and consistent conjectures is greatest when benefits are large and costs are small. We find that large coalitions cannot form. However, small coalitions can result in substantial increases in abatement relative to the non-cooperative outcome.

Is Multilateralism the Future? Sustainable Development or Globalisation as ‘A Comprehensive Vision of the Future of Humanity’

This paper provides an overall evaluation of the outcomes of the World Summit on Sustainable Development (WSSD), which took place in Johannesburg from 26 August to 4 September 2002, in a historical perspective, against the background of earlier major United Nations conferences and General Assembly resolutions on environment and development. It focuses on the political and institutional context of the WSSD and its preparatory process and explores its policy implications for future international cooperation on sustainable development in a globalizing world. Both the results of the formal intergovernmental negotiations and the new phenomenon of partnerships for sustainable development between governments, international organizations, the private sector and other major groups are analysed. The Johannesburg Declaration and the WSSD Plan of Implementation are shown to contain little in the way of political vision, credible new commitments and innovative approaches, likely to reinvigorate the implementation of the objectives of sustainable development as formulated in Rio. Though ostensibly designed to give a new political impetus to multilateralism, the WSSD rather revealed the inadequacy of intergovernmental political governance structures to address the social and environmental consequences of economic globalization.     

基于环境协议的工业园区环境管理模式研究

环境协议制度在我国的实施尚处于摸索阶段,作为先进环境管理方法试验田的工业园区,应率先在环境管理激励机制中采用这一制度并配合环境目标、制衡型环境管理形成制约体系,促进环境协议的践行。本文在探索基于环境协议的工业园区环境管理先进模式的研究中,引入了具有生态工业特点的"绿色星级企业"评价标准,与对企业的优惠措施挂钩,对环境协议制度有一定的实践意义。     

Evaluating a small deposit next to an economically viable gold mine in West Africa from the points of view of the mining company,the government and the local community

This paper addresses the question of evaluating how much the different stakeholders stand to gain from a mining project. By carefully analysing the breakdown of the cash-flows generated, we were able to estimate the amounts received by the local community and by the national community (outside the mining area), the taxes and royalties received by the government and the profits made by the mining company. A real options framework was used to take account of the inherent uncertainty on the commodity price and the reserves, and the operating flexibility (that is, the possibility for the company to stop mining if the commodity price drops and/or the reserves prove to be lower than that had been envisaged). A synthetic case-study of a gold mine in West Africa was used to illustrate how this procedure could be applied in practice. By using the real option framework we were able to envisage scenarios for developing an extension to a deposit as a function of future values of the commodity price. The procedure proposed should provide governments and NGOs with more objective data for making policy decisions.
