FDI chaos and control in China   总被引:1,自引:0,他引:1  
A chaotic system describing the FDI in China is investigated. Two-dimensional map of the system has been controlled by the use of time delay feedback method. Our numerical simulation results have indicated that the FDI chaos in China can be controlled by the intervention of the government. The intervention (or control force) cannot be too big, otherwise the control process has no economic significance. The factors affecting FDI are also discussed in the paper.  相似文献

Given that the usage and complexity of spreadsheets in the accounting profession are expected to increase, it is more important than ever to ensure that accounting graduates are aware of the dangers of spreadsheet errors and are equipped with design skills to minimize those errors. Although spreadsheet mechanics are prevalent in accounting curricula, less attention has been given to design considerations that can reduce the incidence of spreadsheet errors. The extant literature provides evidence of the most common types of spreadsheet errors and explanations as to why they occur. Using the work of Panko and others, this paper outlines a three-step approach for introducing spreadsheet design practices to novice spreadsheet developers. To facilitate design instruction, this paper provides a summary of foundational readings related to spreadsheet errors as well as specific teaching strategies for addressing the most common spreadsheet errors identified in the literature.  相似文献

Previous research has revealed a measurable decrease in student attitude towards the use of computers when they are integrated into teaching. This fall in attitude is thought to reflect the initial diffculties encountered when attempting to use computers and learn acounting techniques at the same time. However, it is postulated that once the students' computer ability has achieved an adequate level, then attitude will recover. This paper reports the results of a continuing investigation into the attitude of second-year undergraduate accounting students towords the use of computers in their studies. The method used was to ask students to complete a questionnaire about their attitudes and self-assessed ability and to undergo a written test of their computer/spreadsheet Knowledge. These data were merged with those from earlier testing to give a two-year data set. The results indicate that the attitude of students to using computers generally continued to fall significantly. However, their ability to use computers and spreadsheets rose. In the case of spreadsheets, this rise in ability was significant. It was found that students who took, as options, additional courses which integrated computers had more positive attiudes and achieved higher scores in the computer Knowledge test than those who did not. This implies that the initial fall in attitude experienced in previous studies was not an isolated temporary phenomenon. The imporvement in ability is observed, but this did not have the expected effect.  相似文献

The interactive student response system (SRS), commonly referred to as ‘clickers,’ is an alternative learning method that has the potential to improve student course (i.e., quiz/examination) performance. Prior SRS studies both within accounting and other academic disciplines have found conflicting results as to its influence on student course performance. This quasi-experimental study re-examines the relationship between the use of an SRS and course performance. We also investigate how using SRS influences student confidence and time spent studying outside of class. Unlike prior SRS related studies, we tested both our SRS class and our control class (with no SRS) in the same academic semester with the same instructor to provide a higher degree of experimental control. Through doing so, we compared the benefit of immediate feedback achieved by SRS to the delayed feedback of traditional assessment formats. Higher in-class performance on multiple-choice quiz items was found for students using SRS versus those who did not use SRS; however, no significant differences in examination performance or overall course performance were noted between the two groups. Students using SRS reported being more confident in their abilities and spent less time preparing for the course outside of class, while maintaining similar overall course performance when compared to those who did not use the SRS. We conclude our study by providing areas of meaningful future research related to the use of SRS.  相似文献

传统西方公务员制度产生于立法权与行政权合二为一的"政党分赃制"时代背景下,其旨在强化行政权,使行政权从立法权中分离出来,脱离政党的控制,这决定了其必然坚持"政治中立"原则。现代西方公务员制度处于行政权一权独大的时代背景下,这决定了必须采取措施重新实现立法权对行政权的有效制衡,表现为淡化公务员"政治中立"原则,加强行政系统对立法系统的"政治回应性"。西方公务员制度在"政治中立"问题上的历史演变本质上是"分权制衡"的政治体制在不同时代背景下有效运作的必然结果。  相似文献

库藏股法和交互分配法是处理集团内部交叉持股的两种会计方法,其理论基础分别为合并报表理论中的母公司理论和实体理论。通过对这两种方法的比较和分析发现,库藏股法有一定局限性,而交互分配法能够消除各种复杂控股关系下成员公司之间的损益和权益的交叉影响,厘清集团各方主体的利益边界,因此,建议我国准则应采用交互分配法。  相似文献

Electronic payment legislation permitted an initially paper substitute digital image of a check, and later the electronic digital image of a check, to be processed and presented for payment on a same‐day basis. By shifting to electronic collection and presentment, Federal Reserve per item check processing costs fell by over 70%, reducing estimated overall U.S. payment system costs by $1.16 billion in 2010. Payment collection times and associated float fell dramatically for collecting banks and payees with consequent additional savings in firm working capital costs of perhaps $1.37 billion and indebted consumer benefits of $0.64 billion.  相似文献

The interrelationship between management control mechanisms and strategy   总被引:1,自引:0,他引:1  
This paper examines the interrelationship between management control system (MCS) mechanisms and strategy. The traditional view is that the MCS is shaped by organisational strategy. More contemporary viewpoints, however, suggest that there may be a two-way relationship between the two variables. That is, MCS shapes, and is shaped by, strategy.We develop two research questions that describe the interrelationship between MCS and strategy, and test them using a public sector entity that experienced a strategic change. A retrospective longitudinal study, spanning five years and involving archival data, interviews and a questionnaire, was adopted. The analysis confirms the existence of a two-way relationship between MCS and strategy. We find that the interactive use of MCS mechanisms helps to facilitate a change in strategy, and that MCS mechanisms change to match a change in strategy.  相似文献

运用灰色关联理论,基于长三角地区2004~2013年制造业和物流业的数据,分别测算了整体制造业以及要素禀赋差异下的制造业与物流业关联度,得出以下结论:(1)制造业发展规模是物流业发展的胁迫因素,居民购买力水平、电信化以及信息化程度是制造业发展限制因素。(2)物流业固定资产投资是劳动密集型行业的重要影响因素,物流业从业人员是资本密集型行业的关键影响因素,公路货物周转量是技术密集型产业的制约因素。(3)不同交通运输方式的货运量与制造业规模关联度普遍较大,但货物周转量与多种制造业因素关联度大。  相似文献

本文通过构建内生生育率的OLG模型,从微观视角考察了延迟退休年龄对生育率、养老金替代率及其个人养老金收入的影响。研究表明:(1)延迟退休年龄会提高均衡时的生育率水平,但提高幅度非常有限。(2)生育率的提高会增加未来劳动力供给,促进养老金替代率上升和养老金收入增加,而延迟退休年龄延长了养老保险缴费期限,也会促进养老金替代率上升和养老金收入增加;但同时,延迟退休年龄将使得预防性储蓄下降,资本积累降低,工资收入下降,养老金收入降低。因此,延迟退休年龄会使养老金替代率上升。当资本产出弹性大于或等于0.5时,延迟退休年龄会使得养老金收入降低;当资本产出弹性小于0.5时,在平均预期寿命较大或养老保险缴费比例较高的情形下,养老金收入会随着退休年龄的延迟而增加,反之,其会随着退休年龄的延迟而降低。进一步地,将模型拓展到包含人力资本的情形,延迟退休年龄仍会提高均衡时的生育率与养老金替代率。  相似文献

房地产产业是关系我国国计民生的支柱性产业,利率是一项重要的宏观调控指标。本文运用经济学相关理论、计量经济学相关模型和统计软件Eviews5.0,利用1998年7月到2008年12月的相关月度数据,对我国利率与房地产市场之间的互动关系进行了实证分析。通过分析,我们发现我国利率与房地产市场之间长期存在协整关系,利率的变化对房地产市场有一定的影响,然而,房地产对这种影响的反映不太敏感且比较滞后,同时,利率的变化几乎不受房地产市场变动的影响,两者互动不足。因此,我们应该加快利率市场化的步伐,同时,结合以市场为导向、推进城市化进程等措施多管齐下治理房地产市场,以使我国房地产市场健康、稳定发展。  相似文献

This study aims to empirically clarify the informational role of interactive discussions with corporate insiders by analyzing how participants’ expectations are affected by their participant comments during analyst and investor days. The results indicate that the tone of management presentations and responses to participants’ comments exhibit no impact on analysts’ expectations of company performance. By contrast, analysts’ earnings forecasts react significantly to comments from their peers (especially star analysts). Furthermore, peer comments contain additional information on analysts’ forecast errors. Finally, analysts whose earnings forecasts diverge positively (negatively) from the consensus are influenced by their peers' negative (positive) opinions. The results suggest that interactive meetings contribute in acquiring information and opinions from other participants (especially informed participants) rather than from corporate insiders.  相似文献
