Do goodwill impairments affect audit opinions? Evidence from China

There has been a steady growth of goodwill impairments in the Chinese stock market since the adoption of the impairment approach in accounting. The influence of goodwill impairments on a firm’s financial position and profitability give reason to doubt its current and future performance. We examine whether auditors, as a crucial external monitor, identify the information risks of goodwill impairments and express their concerns about financial reporting quality in their audit opinions. Using a sample of firms listed on China’s A-share market from 2007 to 2017, we test the association between goodwill impairments and the type of audit opinion received in the same financial period. Our findings are as follows. First, the probability of receiving a modified opinion increases with the amount of goodwill impairments. Second, the positive association between goodwill impairments and modified audit opinions is driven primarily by earnings management risks. Third, this positive association is more salient when auditors are industry experts and there is no auditor–client mismatch. Fourth, auditors are more sensitive to the amount of goodwill impairments than to their mere existence. Overall, we document that auditors perceive goodwill impairments as a signal of information risks and communicate their concerns to investors to avoid litigation.     

早晚航班对飞行员疲劳程度的影响

航空公司为了提高飞机利用率,导致早晚班的比重明显增加.由于飞行员生物节律的改变,致使其疲劳程度加深.为了保证飞行安全,减缓飞行疲劳,合理排班,需要对执行早晚班的飞行员的疲劳系数进行研究.通过对20名飞行员以及10名飞行学员进行电话访谈,了解到他们早晚班的疲劳程度,进而改进西南航空局可用机组疲劳系数的计算公式,优化了每名飞行员早晚班疲劳系数的计算公式.

基于标准数据的创新程度提升路径研究

创新程度在资源配置中的作用日趋明显，但目前创新程度常以专利作为测量值。随着标准在产业发展中引导性增强，作为创新重要产出的标准在创新程度提升中的地位日渐凸显。提出一个以标准数据为依据，通过对标准创新程度值的测量，结合国际国内创新程度四分图模型，研究具体领域创新程度提升路径。以信息技术应用领域标准为分析对象，结合国际标准化组织颁布标准和中国标准，确定信息技术在各应用领域创新现状。结果显示：信息技术在办公系统和银行业务两个领域应用的国际国内创新程度都很低，应在完成产业升级后逐渐淘汰；其在健康关怀领域应用的国际发展前景良好但国内创新程度很低，是重点研究领域。随后，对信息技术在健康关怀领域应用的国际和国内标准具体内容进行对比分析，发现中国与国际发展存在差距，并以国际国内创新程度为依据对位于四分图不同区域的信息技术应用领域创新程度提升提出合理建议。     

农户信用评价模型构建研究--以某市为例

对农户信用评价进行综合分析与研究,构建了由农户基本状况、偿债能力、信誉品德、与本行关系四个方面12项指标的信用评价指标体系;采用层次分析法(AHP)确定了各指标的权重;运用改进后的模糊综合评价法评价农户的信用价值,构建了农户信用评价模型,用样本数据进行模型的实证检验,从而建立了可操作的农户信用风险预警机制。     

我国农村商业银行经营效率研究及预测

农村商业银行是农村金融发展的核心,是服务"三农"、推动乡村振兴战略的可靠保障.以30家农村商业银行为研究对象,运用改进DEA分析方法及灰色预测模型,对其经营效率进行分析及预测.研究表明,我国农村商业银行全要素生产率呈稳步上升趋势,受技术效率与技术进步效率影响较大,在未来保持稳步增长态势,不同地区生产率差异呈收敛趋势.技术效率始终保持相对稳定状态,在临界值1上下浮动,受纯技术进步效率影响较大,地区差异对其影响较小.在此基础上提出合理调整规模、加强金融创新等政策建议.     

The effects of credit default swaps on corporate investment

ABSTRACT

This paper examines how credit default swaps (CDS) affect the corporate investment of the referenced entities. We document a significant reduction in corporate investment after CDS trading, a result that is robust to alternative model specifications and a set of endogeneity tests. Our findings of the increased firm risk and cost of capital support the costly external capital channel. The cross-sectional variations in CDS effects demonstrate that both reduced monitoring and the empty creditor problem might be the underlying forces driving the costly external capital channel. Our additional analysis implies that CDS trading is associated with an enhancement in investment efficiency for firms that are prone to overinvestment.

不平衡时代的创新与创业研究

不平衡是新时代的基本特征。对于创新与创业而言，正是因为时代的不平衡而孕育了更多具有时代特色的创新想法和创业机会，也正是因为时代的不平衡为中国情境下的创新创业研究理论开发带来了更多挑战。在此背景下，首先，客观环境的不平衡来自创业者的主动感知，解决不平衡问题需要提高创业者的创新、创业能力，而能力的提升离不开创业认知加工和积极心理资本发挥作用。创业者通过环境扫描进行信息加工从而引发认知变革。创业团队知识和经验异质性带来了积极的心理资本。其次，合法性是创业企业在不平衡时代中得以生存和发展的"强心剂"。创业学习、关系网络都有助于企业获取合法性、解决新企业的合法性困境。创业企业战略选择和战略导向对于创业合法性也具有直接或间接的影响。最后，创业与创新融合下的商业模式创新逐渐成为不平衡时代的研究热点。商业模式创新需要适宜的资源开发、机会开发或机会-资源一体化开发行为支持，且机会、资源的开发还离不开由"环境-组织-个体"所组成的多层次影响因素发挥的联动效应。
