采用层次分析法和多级模糊综合评估相结合的方法评估山口湖流域社会经济活动对山口湖的生态影响。结果表明:面源污染是山口湖流域生态环境问题的主要矛盾;流域社会经济活动对山口湖的生态影响为二级,即存在一定的社会经济压力,但对湖库生态系统影响较轻,湖库生态结构尚合理、系统结构尚稳定。  相似文献

景观退化评价可以在景观规划中发挥至关重要的作用。为提高景观规划决策过程的透明度,将项目规模评估的规模扩大到更具战略性的地方层面,加强与决策者的有效沟通,提出了该环境影响评估模型。该模型基于等式,LD=ΣkI/V,其中LD表示景观分区的退化系数,ΣkI表示人类活动的累积影响,V量化了该地的脆弱性。LD的价值在于为相关部门制定相应的保护计划的决策提供了支持。景观退化模型的发现适用于可持续性评估,并且可对提案的经济性进行综合评估。  相似文献

We present a probabilistic model based on the one developed by Hernández Mendo and Anguera (Revista de Psicologíca Social, 16(1), 71–93, 2001). Here we have tried to break down the interaction contexts that the opposing teams are able to generate and transform during the game. We are aware that a given player or team does not produce consistent behaviour in similar situations. However, a degree of uncertainty is assumed to exist regarding whether the results obtained are a specific function of the analysis used. In order to carry out this research a category system which optimized that used in the previous model was developed. This system should enable the interaction between teams to be observed within the actual play of a soccer game. A lag sequential analysis was performed on the basis of a coding of the behavioural flow. After describing the behavioural patterns obtained a probabilistic model of the development of play in soccer is proposed.  相似文献

近年来,我国基础设施和公共服务领域广泛采用政府和社会资本合作(PPP)模式。作为一种创新性融资模式,政府与社会资本组建项目公司,共同出资建设运营项目。对PPP项目全面造价管理,明确项目建设成本,政府可对项目公司进行有效的运维绩效监督与有差别的财政支付管理。面对新模式,传统造价管理体系难以适应新需求。本文结合我国国情和PPP项目市场情况,提出我国面向PPP项目的工程造价管理体系构建的方向和措施。  相似文献

The impact of regulation of efforts to minimize costs has been widely discussed, but remains difficult to measure. The sophisticated regulation of water utilities in Wisconsin allows us to attempt such on assessment since different firms can be under different regulatory regimes (price cap or rate-of-return) in the same geographical area at the same time. To measure the impact of regulation on efficiency, we use a stochastic cost frontier approach defining the unobservable efficiency of a water utility as a function of exogeneous variables. Using a panel of 211 water utilities observed from 1998 to 2000, we show that their efficiency scores can be partly explained by the regulatory framework.  相似文献

This article integrates the social surplus approach with input‐output, stock‐flow consistent, social accounting, and social fabric modeling with a structure‐agency methodology to develop a historically grounded model of the economy. The first two sections develop a model of the monetary structure of the social provisioning process. The third section introduces agency into the model in the form of the acting organization. The fourth section uses the social fabric approach and historical context drawn from social structures of accumulation to develop a socially embedded, historically contextualized, structured‐agency model of the economy as a whole. The final section discusses the importance of the model.  相似文献

一、成本效益分析的进一步探讨 1.现值问题 就某一预算规模约束下的若干方案进行成本效益比较,这是在没有引进时间价值的情况下的静态分析。实际上,政府大部分公共项目的建设周期是跨年度的,短则几年,长则十几年甚至几十年。所以,对任何一个跨年度方案的成本效益分析,如果不考虑时间价值因素,可能会得出错误的结论。因为公共支出可以获得效益,但获得效益会因时间不同,其现值也不同。如果现阶段投资可能在未来很长时间以后才能获得收益,那么,其收益就不仅是单纯的资源耗费的收益,还要考虑到获得的时间问题,即时间成本问题,要使公共支出是经济  相似文献

Abstract

A true cost of living (COL) index should compare the cost derived by two consumption levels and two price vectors maintaining the same utility in the two cases. Its application and empirical testing has been, generally, focalized on a temporal perspective. A spatial perspective it is also interesting for economic analysis because it allows for making comparisons of COLs across geographical units. This spatial approach, however, it is not so frequent in the literature. The aim of this paper is to calculate a spatial COL index for the regions of Spain. For this purpose, we use microdata from the 2010 Households Budget Survey (HBS, Encuesta de Presupuestos Familiares) provided by the Spanish Statistical Institute (INE, Instituto Nacional de Estadística). We will denominate this index spatial cost of living index (SCOL). We use a microeconomic approach that keeps the level of utility of households constant across space but allows for substitution among different baskets of goods. The results reveal large differences in COL across the Spanish regions. The estimates of the SCOL index allows for reconsidering regional comparisons in terms of average wages. Even when nominal monetary figures from official Regional Accounts show huge regional disparities, regional differences are largely moderated when the wage figures are corrected by our SCOL index.  相似文献

The process of finding the best fitting model can often be very time consuming and tedious. Most computer programs are very specialized, and many require initial parameter estimates to fit a particular curve. Those that are most useful are ones that are versatile in applications, and ones that allow inputs of rough parameter estimates for finding the optimal ones. This paper focuses on current approaches for fitting observed age-specific demographic data with the multiexponential model schedule and uses two curve-fitting computer programs: MODEL and TableCurve2D. These two programs are assessed according to how well, and how simply, they can be used to fit age-specific fertility, mortality, and migration rates.  相似文献

This article simulates Ronald Coase's transaction cost approach to firm organizing using agent‐based modelling, and contextualizes and contrasts it with a division‐of‐labour/specialization view of the firm that Coase challenged and sought to replace. The simulation tests the firm formation process based on the different implications of transaction costs and specialization as drivers of integration, focusing especially on Coase's rejection of specialization as an explanation for integration in the firm. The results show little support for, and suggest an important shortcoming to, Coase's transaction cost theory. My findings thereby indicate a potential relationship between the specialization theory and Williamson's Transaction Cost Economics, especially the latter's emphasis on co‐specialization through relationship‐specific investments, which helps shed light on TCE's significant influence in the theory of the firm literature.  相似文献

This paper presents two versions of an applied general equilibrium model for the regional economy of Andalusia, Spain, that differ in the closure rule adopted to describe the behavior of the public sector. We use the model with to analyze the impact that the reform of the personal income tax (Act 40/98) implemented in Spain as a whole would have had on the Andalusian region in particular. The model is of the neoclassical variety and includes not only the productive sectors of the economy but also the foreign sector and the government, which are usually absent from theoretical general equilibrium models. Both versions of the model are calibrated by using a Social Accounting Matrix of Andalusia for 1995. The analysis shows that the reform is not self-financing, not even partially, despite governmental claims. It also indicates that there is a positive but smaller than anticipated economic stimulus. In welfare terms, we find that the category of Urban Salaried consumers is the one that benefits the most in real income terms.  相似文献

In this article, edge theorem and boundary theorem, one of the most important results obtained recently in the field of robust control theory, is applied to analyze the economic impact of structural change of production technology in one economic sector, by means of the famous dynamic Leontief input–output model. Two theorems, parallel to edge theorem and boundary theorem, are given in terms of economics in this paper. It is argued that in a sense the complex analysis about the economic impact of production technological changes is equivalent to a one-dimensional computation problem, which is easy to solve. A case study is given in the last section of this paper.  相似文献
