上市公司利润泡沫的剖析

利润是企业经营成果的集中体现,也是衡量企业经营管理业绩的主要指标之一。随着财务报告信息在市场经济中地位的不断提升,部分上市公司为了寻求对自己有利的财务成果,不惜一切手法操纵利润,甚至采用欺诈手段不合法地调整企业的利润,形成了泡沫利润,损害了投资者的利益,影响了我国证券市场的正常发展。本文针对目前上市公司财务报表的利润浮夸现象,就企业泡沫利润的形成原因、手段进行分析,并对如何识别泡沫利润的手段提出了初浅的看法,最后提出了相应的防范措施。     

YAWL语言及其系统的初步研究

工作流和工作流管理系统的合理应用可大大提高办公自动化的程度,而现有的工作流系统在支持工作流基本模式上存在一定的缺陷。一种新出现的YAWL语言较好地支持了工作流现有的基本模式,文章就YAWL语言及其系统的执行方法进行了初步的研究。     

应用二级CES生产函数对中国制造业R＆D投入产出效应的实证研究

进入知识经济时代，科学技术成为重要的生产要素，而科技创新活动中最重要的是R＆D活动。本文试图从生产过程技术关系的角度，实证地研究目前我国企业R＆D活动的投入产出效应。首先我们在生产函数的投入要素向量中引入R＆D投入变量，然后结合相关的研究经验和本文的研究目的，选择二级CES生产函数模型，并对这类模型的参数估计方法进行了探讨。在此基础上，采用2003年上海主要制造业企业的横截面数据，实证研究了企业R＆D投入的产出效应，以及投入要素之间的替代关系，得到了一些具有启发性的结果。

Unlocking the potential of advanced manufacturing technologies

This research examines whether investments in advanced manufacturing technologies (AMTs) such as flexible manufacturing systems (FMS), computer aided design (CAD), computer aided manufacturing (CAM), robotics, etc., are more likely to lead to improved performance if they are supported by improvements in the manufacturing infrastructure of the company. This question is evaluated using data gathered from 202 manufacturing plants chosen from industries generally considered to have relatively high investments in technology.Multiple item scales are developed and adapted from sources in the literature to measure investments in technology, infrastructure, and the performance of the plant. Evidence supporting the reliability and validity of these scales is provided. Hierarchical regression is used to analyze the relationship between technology, infrastructure, and performance. The results suggest that there is an important interaction between the adoption of advanced manufacturing technologies and investments in infrastructure. Firms that invest in both AMTs and infrastructure perform better than firms which only invest in one or the other. Separate analyses on sub-samples of firms with the highest and lowest investments in AMTs show that infrastructural investments have a stronger relationship with performance in the high investment group. Thus, the data indicate that infrastructural investments provide a key to unlocking the potential of advanced manufacturing technologies.     

LOGIT模型在小额农贷信用风险识别中的应用

Identification and estimation of econometric models with group interactions,contextual factors and fixed effects

This paper considers identification and estimation of structural interaction effects in a social interaction model. The model allows unobservables in the group structure, which may be correlated with included regressors. We show that both the endogenous and exogenous interaction effects can be identified if there are sufficient variations in group sizes. We consider the estimation of the model by the conditional maximum likelihood and instrumental variables methods. For the case with large group sizes, the possible identification can be weak in the sense that the estimates converge in distribution at low rates.
