上市公司自愿性披露信息影响因素研究——基于沪、深上市公司的实证检验

本文在文献综述和理论研究的基础上,运用多元回归建立模型,对上市公司自愿性披露信息影响因子进行了实证分析。结果发现,上市公司自愿性披露信息与盈利能力、发行股票类型、会计师事务所规模、公司规模和资产负债率等因素成显著正相关,而与股权集中度及行业类型没有显著相关关系,并对结论进行了相关分析。

无形资产价值的不确定性及管理策略

无形资产对企业产品创新及市场占有发挥着越来越重要的作用,对企业价值的影响也日益重要,对无形资产区别于有形资产特性的认识,有利于资产管理。本文分析了无形资产价值不确定性特性以及形成的原因,并结合无形资产特点,讨论无形资产价值管理的优化的策略。     

An empirical investigation of the roles of prior knowledge and learning activities in technology transfer

This study analyzes 120 university–industry technology transfer projects. A significant positive relationship was found between the learning activities performed by the firm during the development and implementation stages of the technology transfer project and the benefits to that firm from the project. In contrast, prior knowledge of the firm about the existing technology was found to have only a marginal contribution to the project benefits. However, further exploratory analysis based on high and low levels of technical and organizational uncertainty revealed more provocative relationships.     

基于信息系统的企业绩效管理体系——以某石化企业为例

绩效管理思想越来越受到我国企业的关注,然而在具体实践过程中,往往缺乏有力的工具和载体,造成与实际工作流程脱节的现象。根据企业的战略要求和实际情况,构建基于信息系统的绩效管理体系,将为企业提供更加全面、准确、有效的绩效管理工具,提升企业的核心竞争力。     

低保未就业人员求职意愿及影响因素研究

当前城市最低生活保障制度在运行过程中存在的一个突出问题,是低保对象中有劳动能力者的比重日益提高.运用北京市的调查数据,分析了若干经济、社会和心理(文化)因素对低保未就业者的求职意愿及行为的影响.研究发现:贫穷文化和社会资本对求职意愿、家庭规模对求职行为的影响作用具有统计显著性,工作与低保的比较效益以及就业援助则无显著影响.研究结果对进一步完善低保政策具有启发意义.     

R＆D项目影响因素的筛选及优化分析

影响R&D项目成败的因素是多种多样的,来自于方方面面。在实证调研的基础上建立了影响因素初选集,之后针对不同类型的因素,分别运用字2检验、T检验及因子分析的方法对初始因素集进行优化,为项目的评价工作建立更为科学、有效的指标体系。     

倾斜摄影测量中影响模型精度的因素分析

目前,倾斜摄影测量作为一种新技术,经过不断的探索、应用和发展,已开始在测绘行业中大显身手,并取得了不小的成绩。通过三维模型进行的矢量数据采集,其矢量精度完全依赖于三维模型精度。论文以实践经验为基础,定性地分析了在航空摄影、像控测量、模型生产三阶段中,影响模型精度的因素,希望对三维模型的生产起到一定的指导作用。     

Contests with spying: A comment

The subject of the following comment is a paper by Baik and Shogren which has been published in this journal (Vol. 11, No. 3 (1995) pp. 441–451). In their game-theoretic model, Baik and Shogren connect the informational states of the agents in a way which leads to inconsistencies.     

DEALING WITH UNCERTAINTY: ROBUST RULES IN MONETARY POLICY

We argue that in seeking to insure against model uncertainty, monetary policy makers are often ready to trade ex post performance for greater certainty in the outcome. They thus look for rules that although not optimal ex post, have certain properties that qualify them as robust. We apply first, Gul's approach of ‘disappointment’ aversion to describe policy makers' aversion to uncertainty and then define the properties the notion of ‘robustness’ entails. With these two tools we then link the desirability of such robust rules to the degree of policy makers' aversion to uncertainty. We thus show that provided such robust rules exist, a larger degree of disappointment aversion leads to a greater emphasis on robustness in policy implementation.
