建筑垃圾对环境的影响以及对建筑垃圾的资源化利用已成为亟待研究和解决的问题。循环经济把经济活动组成一个“资源一产品一再生资源”的反馈式流程,从而最大限度地减少经济活动对生态环境的影响。通过对建筑垃圾分类、组成和我国目前在处理方法上存在问题的分析,提出应用循环经济的“3R原则”资源化处理建筑垃圾的对策。 相似文献

We search forstrategy-proof solutions in the context of (many-to-one) matching problems (Gale and Shapley, 1962). In this model, whenever the firms can
hire as many workers as they want (the capacities are unlimited) the stable set is a singleton. There exists aPareto efficient, individually rational, andstrategy-proof matching rule if and only if the capacities are unlimited. Furthermore, whenever the capacities unlimited, the matching rule
which selects the unique stable matching is the only matching rule that isPareto efficient, individually rational, andstrategy-proof. 相似文献

Abstract. This paper explores the extent to which majority rule is invulnerable to manipulation by individuals and coalitions, even
when majority rule is used to select more than one alternative. The resulting rule may or may not be strategy-proof, depending
on the size of the coalitions that can form, and on the nature of the individual preferences over sets of alternatives. No
individual can manipulate with respect to a wide family of preferences over sets. The only restriction on the domain of true and revealed
individual preferences is that the selection rule is always well defined.

We thank two anonymous referees for suggestions that have significantly improved the paper. We are also grateful to l'Université
de Caen for sponsoring a Workshop on Social Choice Theory, where a first draft of this paper was presented in May, 1999, and
to the workshop participants for helpful observations. Work on the final version of the paper was done while one of the authors
was a guest of the Project on Intergenerational Equity supported by the Ministry of Education, Science, and Technology of
Japan. We are grateful to the Ministry and to the project leader, Professor Kotaro Suzumura, for their support. 相似文献

In this paper, data envelopment analysis (DEA) techniques are applied to the French nursing home industry in order to address two policy issues. The first involves nursing home size and returns to scale, while the second deals with the potential effects of a change in nursing home reimbursement from a flat rate to one based on the severity of case-mix. To accomplish this, our analysis expands on the existing nursing home literature to analyze technical and allocative efficiency along with budget-constrained models rather than the more common direct input-based distance function. Technical efficiency is evaluated via an indirect output distance function while allocative output efficiency is computed with a cost indirect revenue function. The findings suggest that system-wide efficiency and equity may result from coming reforms since payments would more accurately reflect resource use. 相似文献

In this paper I propose an alternative to calibration of linearized singular dynamic stochastic general equilibrium models. Given an a-theoretical econometric model as a representative of the data generating process, I will construct an information measure which compares the conditional distribution of the econometric model variables with the corresponding singular conditional distribution of the theoretical model variables. The singularity problem will be solved by using convolutions of both distributions with a non-singular distribution. This information measure will then be maximized to the deep parameters of the theoretical model, which links these parameters to the parameters of the econometric model and provides an alternative to calibration. This approach will be illustrated by an application to a linearized version of the stochastic growth model of King, Plosser and Rebelo. 相似文献
