上市公司如何在非理性世界中确定股权回报率

确定股权回报率是进行长期投资决策的关键步骤,但在现实非理性世界中难以直接运用传统财务理论所推荐的资本资产定价模型来确定股权回报率。针对FAR与NEER方法,本文首先探讨这两类方法的理论依据并揭示其本质内涵,然后说明:在非理性世界中,如果上市公司管理者追求公司价值最大化目标,那么就应该基于公司项目的基本风险来确定股权回报率;相反地,如果管理者追求近期股价最大化,那么就应该基于市场投资者的预期来确定股权回报率。

An effective going concern prediction model for the sustainability of enterprises and capital market development

The purpose of this study is to construct a two-stage effective and innovative going concern prediction model to predict going concern doubt for the sustainability of enterprises and capital market development. Samples of this study are the companies listed on the Taiwan Stock Exchange or the Taipei Exchange, totalling 196 companies and including 49 companies with going concern doubt and 147 normal companies (with no going concern doubt). The data are taken from the Taiwan Economic Journal (TEJ) and the Market Observation Post System during the period from 2001 to 2016 (totalling 16 years). This study adopts a two-stage way to construct the going concern prediction models. In Stage I, the traditional statistical method of stepwise regression (SR) and the data mining technique artificial neural network (ANN) are applied to select the important variables. In Stage II, two decision tree algorithms (data mining techniques): classification and regression tree (CART) and C5.0 are used to establish the prediction models. The results show that the SR + CART model has the highest going concern prediction accuracy, with an overall accuracy of 87.42%.     

新形势下中国企业对外投资的区位选择综合决策模型

对外直接投资的区位选择是跨国公司管理决策的关键点,在很大程度上决定着投资的成败,现有理论在解决了众多为何要对外投资的问题,但在向何处投资的问题上却没有理论和模型可以全面解释。本文建立了新的对外直接投资的区位选择决策二级系统模型,将影响因素按影响效果和属性分类,利用模糊优选方法解决了非量化因素的量化可比性问题。并将本国与外国因素融入同一模型,同时解决了是否要进行对外投资和向何处投资两个问题。     

基于供应链的集中式战略采购研究

在当今竞争激烈的市场环境中,采购管理逐渐成为企业新的利润创造源.基于供应链的集中式战略采购是指企业将采购职能和供应商资源跨部门集中管理,通过加强供应商合作,实现供应链总成本最低化和效率最大化的采购模式.该采购模式作为战略采购的深化,能够有效推动企业竞争力的提升.本文首先介绍集中式战略采购的内涵和特点,接着对该模式的竞争优势进行了深入分析,最后提出应用建议.

Diversity in foresight: Insights from the fostering of innovation ideas

Foresight activities have often provided support for objectives such as priority-setting, networking and consensual vision-building. In this paper, we draw upon complementary evolutionary perspectives and discuss these objectives from the viewpoint of diversity which may be vital in contexts characterized by technological discontinuities and high uncertainties. We also argue that although the scanning of weak signals has been widely advocated in such contexts, the solicitation of ideas for prospective innovations may provide more focused, action-oriented, and comparable reflections of future developments. For the analysis of such ideas, we develop a collaborative foresight method RPM Screening which consists of phases for the generation, revision, multi-criteria evaluation, and portfolio analysis of innovation ideas. We also report experiences from a pilot project where this method was employed to enhance the work of the Foresight Forum of the Ministry of Trade and Industry in Finland. Encouraging results from this project and other recent applications suggest that RPM Screening can be helpful in foresight processes and the development of shared research agendas.     

网络口碑信息对消费者购买决策的影响：一个实验研究

本文通过实验法考察了网络口碑信息对消费者购买决策的影响，就网络口碑的影响力在口碑信息类型、传播方向和产品涉入度不同的情况下会表现出哪些差异等问题作了分析。实验结果支持了所提出的6项假设，网络口碑信息对于消费者购买决策的影响力可能会随着口碑传播方向、信息类型以及产品卷入度的不同而呈现出显著差异的预测得到了证实；信息类型、传播方向和产品卷入度之间所存在的交互效应也会明显地作用到网络口碑对消费者购买决策的影响效果。     

品牌进入消费者考虑集的决策规则——基于牙膏产品品牌的实证研究

消费者考虑集是消费者决策过程中的重要阶段，品牌只有进入考虑集才有可能被最终购买。本研究在上海以牙膏作为测试对象检验了牙膏品牌进入考虑集时消费者所依据的决策规则。实证结果显示，消费者主要使用排除式决策规则、非权重的补偿式决策规则和权重的补偿式决策规则。
