Evaluating Projects and Assessing Sustainable Development in Imperfect Economies

We are interested in three related questions:(1) How should accounting prices be estimated?(2) How should we evaluate policy change in animperfect economy? (3) How can we check whetherintergenerational well-being will be sustainedalong a projected economic programme? We do notpresume that the economy is convex, nor do weassume that the government optimizes on behalfof its citizens. We show that the same set ofaccounting prices should be used both forpolicy evaluation and for assessing whether ornot intergenerational welfare along a giveneconomic path will be sustained. We also showthat a comprehensive measure of wealth,computed in terms of the accounting prices, canbe used as an index for problems (2) and (3)above. The remainder of the paper is concernedwith rules for estimating the accounting pricesof several specific environmental naturalresources, transacted in a few well knowneconomic institutions.

The Change of Ecological Footprint and Its Effect on Sustainable Development in Beijing of China

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.

长江流域的生态安全与对策研究

长江流域生态安全对中国可持续发展具有重要的战略意义。由于长江上游地区是水土流失的重灾区和主要的污染源,三峡工程的建设也使得长江流域上游地区生态环境的综合治理更显紧迫,因此维护长江流域生态安全的重点在于上游地区的综合治理,其关键是加大长江流域生态建设的投入。文章提出了要切实加强长江流域的统一管理,加强立法体系的建设,积极推进西部大开发战略和尽快建立绿色GDP核算体系等政策建议。

我国农业生态系统营养循环链的断裂与重建

完整的营养循环是农业生态系统健康、可持续发展的重要保障。我国传统农业属于环境友好型生态农业。农业生态系统的营养循环结构完整，持续健康、繁荣。但是，随着工业化、城市化、市场经济的发展以及农业耕作方式的转变，农业生态系统营养循环的结构遭到严重破坏，导致一系列资源、环境、经济与社会问题。通过秸秆还田以及城市生活废弃物（排泄物、厨房垃圾等）向农业生态系统的返还，重建农业生态系统完整的营养循环，是我国农业生态系统持续健康发展的必由之路。
