排污权有偿使用阶梯式定价研究——以化学需氧量排放为例

依据河南省2010年污染源普查数据,分析了不同行业化学需氧量排放的公平性问题,基于不同行业经济贡献与排污量之间的差异性的基础上,参考阶梯水价和电价的制定思路,提出了排污权阶梯式定价,并对其内涵与经济学特征进行了分析,最后,在恢复成本法定价的基础上制定了河南省化学需氧量有偿使用阶梯式价格。     

Adopting a Unit Pricing System for Municipal Solid Waste: Policy and Socio-Economic Determinants

Concerns about the environmental and aesthetic damages of municipal solid waste pollution have triggered policy reform at all levels of government. As part of this effort, public officials are integrating market-based policy instruments such as unit pricing into their solid waste plans. Despite the economic advantages of unit pricing, constituency response has been mixed and hence adoption rates have been below expectations. If the associated gains are to be realized, public officials must identify the key factors that influence this decision. To that end, this research empirically estimates the determinants of unit pricing adoption at the community level of analysis. Based on data for all cities and towns in Massachusetts, the results indicate that demographics, socio-economic attributes, fiscal capacity, and policy instruments influence this decision.     

Efficiency and Equity in Natural Resources Pricing: A Proposal for Urban Water Distribution Service

This paper focuses on the design of optimal prices for urban water distribution service. In this context, pricing should be aimed at achieving efficiency, equity, financial aspects, and/or public acceptability and transparency. The proposed tariffs are based on the theoretical frameworks suggested by Ramsey (1927) and Feldstein (1972). As a prior step, estimations of urban water demands and water costs are carried out for the Spanish municipality of Seville. Finally, an empirical comparison, in welfare terms, is conducted between the proposed tariffs and those applicable in the year 2000.     

我国可持续发展农业土地利用评价体系研究

可持续发展农业土地利用是社会经济系统可持续发展的关键、对可持续发展农业土地利用的评价有利于指导这一战略的实现。可持续发展农业土地利用包括农地总量动态平衡和农地永续利用两个方面。本文试图提出一个涉及这两方面的可持续发展农业土地利用的评价指标体系。     

Water accounting for the Orange River Basin: An economic perspective on managing a transboundary resource

The framework for water accounting is applied to an international river basin, the Orange River Basin, which is shared among Botswana, Namibia, Lesotho and South Africa. Each of the riparian states faces water constraints and relies increasingly on shared international water resources. The countries have adopted the principle of an economic approach to water management, once basin human needs are met, and all but Lesotho have constructed national water accounts to assist in water management. The water accounts for the Orange River Basin bring an economic perspective to water management at the regional level. The accounts include supply and use tables, which are used to compare the contribution to water supply from each riparian state to the amount used. The water accounts are then linked to economic data for each country to calculate water use and productivity by industry and country. There are considerable disparities in water productivity among the countries, which should be taken into account in future decisions about water allocation, pricing and infrastructure development.
