The agricultural high-teeh investment project (AHIP) is eharaeterized by technology-intensive, high risk and great profit. This article analyzes essential factors of the risks of the agricultural high-tech investment projects and the traditional risk evaluation method of agrtcultral projects. We think that the applications of the sensitivity, analysis and probability ore defer. Therefore; this article introduces a structural model to evaluate the risks of the agricultural high-tech investment projects and the system of the concrete evaluation indexes.  相似文献

Summary. In order to explain in a systematic way why certain combinations of market, financial, and legal structures may be intrinsic to certain capabilities to exchange real goods, we introduce criteria for abstracting the qualitative functions of markets. The criteria involve the number of strategic freedoms the combined institutions, considered as formalized strategic games, present to traders, the constraints they impose, and the symmetry with which those constraints are applied to the traders. We pay particular attention to what is required to make these strategic market games well-defined, and to make various solutions computable by the agents within the bounds on information and control they are assumed to have. As an application of these criteria, we present a complete taxonomy of the minimal one-period exchange economies with symmetric information and inside money. A natural hierarchy of market forms is observed to emerge, in which institutionally simpler markets are often found to be more suitable to fewer and less-diversified traders, while the institutionally richer markets only become functional as the size and diversity of their users gets large.Received: 5 June 2003, Revised: 18 November 2003, JEL Classification Numbers: C7, G10, G20, L10, D40, D50.

传统的会计准则制定模式中都特别强调了会计概念、会计原则和会计规则的突出地位,因而有了原则导向(或基础)的会计准则制定模式、规则导向(或基础)的会计准则制定模式以及安然等财务欺诈案件后美国目标(实际是概念)导向的会计准则制定模式的说法。通过对现有会计准则制定模式的反思,我们认为会计概念、会计原则和会计规则不应是会计准则制定的导向或基础,而是会计准则结构体系的构成要素。在本文中,我们对其各自的含义界定和功能定位进行初步探讨,旨在为建立我国的会计概念框架,完善会计准则体系提供理论参考。  相似文献

Comprehensive transportation evaluation objects using multi-objective decision method is a process of choosing the best one from a few objects through calculating, analyzing, and comparing the index system. The result may be different because of the difference of the index weight and index value. Therefore, sensitivity analysis should be one of the necessary parts of the decision-making. It is desired to give the index with higher sensitivity and its varying scope to control the index strictly during the execution process. This paper derives transfer index weight, which changes the rank evaluation order of the projects. Meanwhile, a simple, effective and practical method based on sensitivity district and sensitivity matrix is proposed for the sensitivity analysis of decision-making. As an example, the index sensitivity in decision-making of some provinces comprehensive transportation objects, and their influence on the final decision are discussed.  相似文献

Summary This paper characterizes the optimal policy for a model in which manager may adopt an endogenous number of projects but has only limited resources to devote to their evaluation and maintenance. In any period, the manager may discard any subset of existing projects but may evaluate only one existing or one new project which is then either discarded or restored. Both its current return and the probability with which a project may be restored depends only on the number of periods since its last evaluated. For a manager whose objective is to maximize the sum of discounted returns, the optimal policy takes one of two forms. A discard policy specifies that the manager evaluate a new project in each period and discard current projects at some critical age. An age inspection policy specifies that the manager evaluate a new project only if all current projects are sufficiently young.Support from the C. V.

在问卷调查的基础上,构建我国中西部县域PPP模式的风险因素评价指标体系。经过风险指标权重的计算,从19个风险中筛选出9个制约中西部县域PPP项目的关键风险因素,并通过相关检验和因素分析将其划分到4个关键风险组群,分别为政治风险、经济风险、市场环境风险和合作风险。结果显示:政治风险为制约PPP发展的最主要风险组群,而项目收益不足则是评分最高的单项风险因素。  相似文献
