企业综合绩效评价方法研究——基于ANP、平衡计分卡和绩效棱柱理论

分析了平衡计分卡和绩效棱柱两种绩效评价体系的特点,提出了从利益相关者角度出发,以扩展的平衡计分卡为框架,意图建立一个集成利益相关者的满意、利益相关者的贡献、企业经营和企业战略的企业综合绩效评价体系。从定性与定量相结合的角度出发对企业综合绩效评价指标数据进行量化和评价,运用网络分析法ANP确定指标的权重,从而体现了企业综合绩效评价体系之间存在的相互影响和作用。最后,选择了一家电脑企业进行了案例分析。

基于成本-效益分析的企业技术创新策略选择

以企业效益最大化为分析前提,假设企业仅面临着开展或不开展技术创新两种策略选择,并假设两种策略的收入与成本函数均为线性函数.在此基础上运用成本-效益分析法,讨论在不同情况下企业的技术创新策略选择及其判别条件,并对分析结论的经济涵义给予解释.

房地产预警指标体系及综合预警方法研究

 本文在对常用的房地产预警指标体系选择方法及筛选流程进行分析的基础上,提出了一种主、客观相结合的房地产预警指标选择方法,即先采用综合分析方法对指标进行初次选择,然后用聚类分析和相关分析相结合的方法进行再次选择。最后建立了武汉市房地产预警指标系统,并进行了房地产综合预警。     

证券市场并购目标的财务特征分析和预测研究

应用自组织映射神经网络（SOM）和Hopfield神经网络模型对上市公司并购目标公司进行了实证研究。SOM网络的聚类分析表明目标公司可分为6个类别,各类别之间差异较大,目标公司明显区别于非目标企业,在总体上具有盈利能力低、经营能力差、偿债能力较强的特点。Hopfield网络模型的预测结果显示,目标企业的平均预测准确率为80．69％,非目标企业的预测准确率为61。33％,由于并购交易发生受多种因素影响,财务指标与其它因素相结合方能提高模型预测的效果。     

Ambiguous Criteria Weights in AHP: Consequences and Solutions*

Two related streams of criticism of the analytic hierarchy process (AHP) have not yet been satisfactorily resolved, although both date from the early 1980s. The first relates to ambiguity in the meaning of the relative importance of one criterion as compared to another. The second is concerned with reversals of rank alleged to be possible when new options are introduced in an AHP problem. Both proponents and critics of AHP agree that rank reversals occur, but disagree on the legitimacy of such reversals. This paper shows that there is a necessary correspondence between the manner in which criteria importances are interpreted and computed and the manner in which the weights of the options under each criterion are normalized. In general, if this relationship is ignored, incorrect weights are generated for options under consideration regardless of whether new options are added or deleted. A rank reversal on the addition of an option is merely symptomatic of this fact, and such reversals do not occur when the correspondence condition is met.     

Some Cautions on the Measurement of User Information Satisfaction*

User information satisfaction (UIS) is important because of its potential effects on MIS department goals, quality of user work life, and extent of voluntary usage of systems. Reliable measurement of UIS is important for providing evaluative information for both researchers and practitioners. This study used 92 managers and executives as subjects to compare the test/retest reliability of a widely used, 13-scale UIS instrument together with four summary questions under experimental and control conditions. The summary questions behaved more reliably than the detailed questions for all groups, perhaps because of problems with scale units and origins and with item heterogeneity. This suggests that researchers need more reliable measures of UIS and that practitioners need to exercise caution when collecting and interpreting UIS scores.     

DIVERSIFICATION GAINS FROM INCLUDING REAL ESTATE IN MIXED-ASSET PORTFOLIOS*

Diversification gains in mean-variance efficiency derived from including real estate in financial asset portfolios are examined. Optimal financial and mixed-asset portfolios were generated by selecting from an investment universe including several distinct financial and real estate media. Deficiencies of previous studies were overcome by employing data with improved representativeness and comparability. The efficient mixed-asset portfolios dominated the efficient financial asset portfolios implying that purely financial asset diversification is inefficient. The optimal mixed-asset portfolio prescribed that approximately two-thirds of the investment wealth be allocated to real estate and one-third to the financial media.     

积极语篇分析:和谐的态度韵律研究——以汉语导游讲解词为例

文章从语篇分析的新视角——积极语篇分析入手,以评价理论为框架,试图探寻在导游讲解词中,导游是如何缩短自身以及景点与游客之间的距离,从而达到宣传景点、传播文化的交际目的的。作为一个较新视角的积极语篇分析并没有固定的分析方法和模式,本文融合了语类理论、评价理论和态度韵律理论构建了态度韵律研究的分析模式,并将它运用到导游讲解词的分析中。通过研究本文发现导游讲解词作为一种机构语言确是语类的一种,是分阶段的具有目标朝向性的社会过程,并有其独特的语类结构。主要包括五个阶段:欢迎词、整体介绍、具体讲解、评价和欢送词。态度韵律是一个具有层级性的结构,存在于语篇之中,具有普遍共性,导游讲解篇词中的态度韵律有其特性。态度韵律的运作有着内在机制,态度韵律可分为发散韵、波浪韵和梯度韵三类,这三类结构具有动态平衡的特质,它们共同流动于语篇之中使其成为和谐统一的整体。
