The impact of tax holidays on earnings management: An empirical study of corporate reporting behavior in a developing-economy framework

This study investigates whether foreign investment enterprises (FIEs) in China alter their corporate reporting behavior in response to a known schedule of tax-rate increases. The context of this investigation is a tax-incentive scheme that allows firms to pay taxes at a reduced rate for a limited period of time, and then at a higher rate when this period expires. If managers attempt to maximize firm value by minimizing tax costs, then the spread of tax rates in the periods surrounding the rate change may provide a substantial incentive for them to accelerate revenue and defer expenses. Consistent with this hypothesis, the empirical results indicate that firms report significantly higher discretionary current accruals for the years before tax-rate increases. The evidence, which indicates that firms manage earnings upward to take advantage of lower tax rates that are available in certain years, has important implications for tax policymakers.     

英国的非公开权益资本和风险投资

英国是欧洲风险投资和非公开权益资本的发源地。在欧洲国家中,英国的风险投资和非公开权益资本起步最早,发展也最快。从1979年算起,英国风险资本投资额和非公开权益资本增长了100多倍。2005年,在欧洲的风险投资市场上,英国的风险资本总额占欧洲风险投资额的40￣50%,在欧洲是当仁不让的“大哥大”,在世界范围内仅次于美国。本篇文章主要介绍了风险投资(VentureCapital,VC)及非公开权益资本(PrivateEquity,PE)的最新概念和从属关系以及英国的风险投资及非公开权益资本的历史、结构、规模、投资趋势、投资阶段、投资领域、地理特征、知名风险企业、投资表现等,以此从数据和分析的角度使中国的风险投资领域及非公开权益资本领域的从业人员以借鉴、启迪的作用。     

建设工程项目管理(PM)模式探讨

随着项目规模的扩大和投资主体的多元化，业主对建设项目管理提出综合性、系统性和全生命期集成管理的更高要求。我国政府投资项目推行代建制也要求相匹配的项目管理模式。根据在工程管理教学和实践中体会，探讨建设工程项目管理（PM）模式的特点和优势，提出应用PM模式的几点建议。     

Non-coercive influence: Scale development and validation based on resource and relational paradigms

To overcome competition in an increasingly network dependent market, retailers are required to influence upstream channel partners while sustaining relationships. However, the contemporary supply chain literature has not sufficiently leveraged the resource and relational paradigms to examine influence. Grounded on resource dependency theory and commitment-trust theory paradigms, this study describes conceptualization and operationalization of a 12-item scale for measuring non-coercive influence on upstream channel partners in retail supply chain management (R-SCM) context. The study is based on responses from 547 retail professionals in India obtained over four successive surveys. Psychometric properties were assessed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The proposed scale demonstrates construct validity. Invariance-testing carried out over 4-levels of increasingly demanding equivalence confirmed cross-validation. Nomological validity of the scale was tested by evaluating association with suppliers’ intention to cooperate. The results indicate existence of three dimensions of non-coercive influence: collaborative intent, market intelligence dissemination, and operational support. Retailers can use the scale to assess their personnel's non-coercive influence behavior over suppliers.     

SCI收录河北科技大学学术论文的统计分析(2003-2007年)

SCI是衡量一个机构学术水平和科研能力的重要因素,尤其能反映自然科学基础研究的学术水平。笔者以美国ISI公司的Web of Knowledge网络数据库为依据,对2003-2007年间以河北科技大学为著者署名单位被SCI收录及引用的科技论文进行了统计分析,最后提出了增加中国科技论文被收录数和被引用率的一些建议。

硒拮抗氟引起肺脏、脾脏损伤中肥大细胞变化的观察

采用Wistar大鼠50只分别饮用含氟化钠150mg/L和含氟化钠150mg/L加不同剂量亚硒酸钠水.二个月后断头处死,取肺,脾作肥大细胞(MC),糖元PAS反应,DNA(Feulgen)反应观察.结果:肺,脾氟化钠(150mg/L)组肥大细胞与正常组比较,无明显变化.糖元PAS反应,DNA(Feulgen)反应减弱;氟化钠(150mg/L)加亚硒酸钠(2.0mg/L)组,肥大细胞显著增加,糖元PAS反应,DNA(Feulgen)反应程度增强.提示:硒在保护氟引起肺,脾损伤过程中,可能对肺、脾的肥大细胞增生和活化起促进作用.

基于截尾分布理论预测开放式基金大额赎回量

提出了开放式基金的巨额赎回量和大额赎回量的概念,将复合泊阿松分布和截尾分布理论运用在大额赎回量概率计算之中,得到了计算公式。由于开放式基金流动性风险主要来自于大额赎回量,因此使用截尾分布方法预测未来近期的大额赎回量更合适。推导出了正态分布下大额赎回量的期望和方差计算公式。为基金管理人合理规避这种流动性风险提供了一种预测方法。     

基于负债的中小企业经营策略

由于我国金融市场体系不健全和中小企业自身的原因,中小企业在发展过程中仍面临着较多问题,尤其资金短缺成为制约中小企业发展的瓶颈,负债更成为维持中小企业发展的一条捷径。中小企业应充分结合自身的特点、所在的外部融资环境、融资成本以及企业对资金的需求等要素,进行适度负债经营,选择适合自己的筹资方式,有效利用负债经营的有益之处,最大限度地提高经济效益。
