中华经济圈上市公司审计报告比较研究

本以中华经济圈上市公司审计报告为研究对象，分别就大陆、香港、台湾三个地区审计报告的内容与格式加以比较研究。两岸三地在审计观念、独立审计规范性质、审计责任和执业关注等多个方面的差别是形成大陆、香港和台湾地区上市公司审计报告差异的主要原因。因此，合理地借鉴港台地区审计报告体系先进的做法，全面改革和完善大陆审计报告体系和独立审计规范体系，将是我们积极迎接审计市场国际化的必要措施。

基于最短路的配送中心选址决策与应用

物流作为“第三利润源泉”,对现代的经济活动影响日益明显,越来越引起人们的重视。配送是物流的核心问题,研究如何选择合理的配送中心和配送路线来降低配送运输成本,对物流总成本的节约具有十分重要的意义。论文从配送运输成本最小化目标出发,对单一配送中心选址以及一对一配送路线优化问题进行分析,并分别建立重心法选址模型和最短路算法模型,进行实例分析。

Connecting ‘talent’ meanings and multi-level context: a discursive approach

Abstract

Through an in-depth, multilevel case study of a professional services firm, this paper illuminates what stakeholders mean when they use the term ‘talent’. The paper underlines how various contextual factors including, workforce composition, ownership structures and individual perceptions influence talent meanings within an organisation. Our analysis of talent phenomena at a multiplicity of levels illustrates that it is not only about the words, phrases, and terms employed when talking about talent that requires examination. There is a need to deliberate on the meanings that underpin the talk because while stakeholders may talk the same way they may mean different things. The paper makes a key theoretical contribution through specific recognition of the importance of thoughtful reflection of how stakeholders discursively construct meanings because ‘talent’ is a concept, which requires translation via talk to become meaningful within the material world and these meanings are influenced by context. Thus, we cannot infer, that talent meanings radiate within organisations, nor across organisational boundaries, industries or countries because discourses arise and materialise within specific contexts and we must acknowledge that talent discourses can not be removed from the context in which they operate.

ML– and semiparametric estimation in logistic models with incomplete covariate data

ML–estimation of regression parameters with incomplete covariate information usually requires a distributional assumption regarding the concerned covariates that implies a source of misspecification. Semiparametric procedures avoid such assumptions at the expense of efficiency. In this paper a simulation study with small sample size is carried out to get an idea of the performance of the ML–estimator under misspecification and to compare it with the semiparametric procedures when the former is based on a correct assumption. The results show that there is only a little gain by correct parametric assumptions, which does not justify the possibly large bias when the assumptions are not met. Additionally, a simple modification of the complete case estimator appears to be nearly semiparametric efficient.     

国外并购绩效评价方法研究综述

20世纪全球经历了5次企业并购浪潮,并购已经成为现代企业尤其是大型企业和高成长企业快速扩张和整合的重要手段之一.企业并购的之后的效果如何,如何来评价并购的绩效,国外学者从不同角度做了大量的研究,但数十年的研究至今没有一个统一的结论.本文总结了30多年以来国外学者有关企业并购绩效研究的重要文献,在此基础上将国外并购绩效的评价方法分为财务评价、股票评价和其他评价三类,并指出了并购绩效评价方法中存在的问题.
