CEO Stock‐Based Incentive Compensation and Firm Performance: A Quantile Regression Approach

This study employs the quantile regression model to examine the non‐monotonic impact of CEO stock‐based compensation on firm performance, using the data for U.S. non‐financial firms from 1993 to 2005. The results indicate that while the impact of CEO stock‐based pay on firm performance is positive for firms in the higher earnings quantile levels, the impact is negative for firms in the lower levels. In addition, the “V‐shaped” relationship between CEO stock‐based pay and firm performance satisfactorily explains the longstanding disagreement among earlier studies with regard to whether CEO stock‐based pay can enhance firm performance. Furthermore, the quantile‐varying pattern of the impact of stock‐based compensation on firm performance is robust after controlling for the industrial and yearly effects. It is also robust to the use of the pay‐for‐performance sensitivity as an alternative explanatory variable or the market‐based measure of performance as the dependent variable, or the consideration of the suspected endogenous problem between firm performance and stock‐based compensation.     

城市群高质量发展的理论逻辑与路径选择

现代化后发赶超要求以城市群作为主体空间形态,实现效率增进、功能跃升、均衡发展和开放合作.城市群正日益成为托起中国现代化的巨擘,目前我国19个城市群之间规模结构差异较大,以东部城市群发展质量最高.城市群发展失衡的原因在于,城市群城镇体系不合理、公共服务一体化存在障碍、区域一体化发展体制机制有待健全、城际间综合交通网络体系亟待完善.适应现代化发展要求,我国需要在城市群加快推动形成快速便捷的综合交通体系与一体化发展体制机制,以都市圈为载体优化城市群空间格局与推动城市群协同发展,加快构建包容共享的公共服务体系,提升城市群的开放发展水平,引领中国现代化发展.     

新冠疫情全球蔓延对我国就业的影响及机制分析

新冠疫情全球蔓延对需求端与供给端都造成巨大的冲击,评估此次疫情对我国就业的影响及机制分析变得重要.基于统计比较和使用DID模型,我们研究表明:(1)新冠疫情爆发前,我国总体失业率基本稳定,地区间失业差异趋于缩小;2020年疫情爆发后,我国城镇调查失业率出现明显上升,但其影响在下半年趋于缓解.(2)新冠疫情全球蔓延对我国就业市场产生显著不利的冲击,但对我国31个大城市就业的不利冲击要相对小于总体城镇.新冠疫情导致我国城镇调查失业率总体上升0.31个百分点,导致全国31个大城市调查失业率总体上升0.218个百分点.新冠疫情爆发4个月后我国就业受到的不利影响开始减小.(3)新冠疫情对我国制造业和服务业的经济活动均造成不利冲击,进而对我国就业造成显著不利的影响,且对我国服务业经济活动产生的不利冲击更大.据此,需要严格防控国内疫情反弹,提升一流的营商环境,对受疫情不利影响的企业和劳动者提供优惠政策支持,出台人力资本政策支持建立国家高端人力资本储备池,拓展数字贸易、数字平台等就业创业.     

股指成份股调整与公司盈余管理——基于一项准自然实验的研究

文章以沪深300指数2007年6月至2018年6月23次调整的成份股和同期公布的备选股为研究样本,考察了成份股调整对公司盈余管理的影响.研究发现:(1)与备选股相比,成份股调整后公司的应计盈余管理没有受到显著影响,而真实盈余管理水平则显著下降;(2)区分真实盈余管理的不同类型,成份股调整主要通过异常现金流降低了真实盈余管理水平;(3)在持续时间方面,成份股调整对真实盈余管理的影响在调入指数三年之后依然存在;(4)成份股调整降低真实盈余管理的作用在独立董事比例低和非国有企业样本中更加显著.上述结果表明,成份股调整的"监督效应"降低了公司的真实盈余管理水平,且在其他监督渠道较弱的情况下更加显著.文章丰富了成份股调整经济后果和盈余管理影响因素的研究,并有助于监管者和投资者认识股票指数调整对公司行为和会计信息的现实影响,以监管和防范投资风险.

卖空限制与收益可预测性——A股融资融券制度的证据

基于A股市场融资和融券余额的巨大差距,本文拓展了Hong et al.(2016)的理论模型,在融券端和融资端分别找到了影响股票收益率的变量:融券比率(融券余额/流通市值)和融资回补天数(融资比率/日均换手率)。进一步,本文利用组合价差法和Fama-MacBeth横截面回归法,实证检验了A股市场中融券比率与融资回补天数解释和预测股票收益率的能力。实证结果表明,在存在融券限制条件下,融券比率相比融券回补天数(融券比率/日均换手率)能更好地代表套利者对股票价格高估程度的看法,根据融券比率构建的等权重多空组合能带来月均1.58%的显著收益;而由于融资约束相对较少,融资回补天数相比融资比率(融资余额/流通市值)能更好地代表套利者对股票价格低估程度的看法,根据融资回补天数构建的等权重多空组合能带来月均1.28%的显著收益。实证结果与本文存在融券数量限制下的理论模型相符,且该收益率不能被多因子模型和常规股票特征所解释。     

The joint effects of social identity and institutional pressures on audit quality: The case of the Chinese Audit Industry

This article examines how social identity links institutional pressures and audit quality. Combining institutional theory and social identity theory, we theoretically argue that the interaction between social and institutional forces shapes audit quality. Through an analysis of Chinese audit firms from 2000 to 2007, we show that isomorphic imitation has a more significant effect on firms belonging to the same-identity group than firms across cross-identity groups; foreign-affiliated audit firms are more willing to conform to normative pressure from professional networks than local firms; and foreign-affiliated firms are coerced to adapt to the local government’s expectation, particularly when they have a geographically concentrated customer base. We further reveal that a larger customer base attenuates within-identity group imitation but strengthens cross-identity group imitation. The results shed light on the role of social identity in shaping conformity in the audit industry, thus contributing to international convergence–divergence literature and institutional theory.     

双弧焊对10Ni3CrMoV钢性能影响的研究

对921A钢进行了热模拟试验,同时对该模拟试样作了50℃冲击功测试,结果表明,试验钢经过双丝焊接热循环后,热影响区各区的低温冲击功普遍低于母材。将冲击功最低试样做光学显微组织分析,结果表明试样的组织由母材的回火索氏体组织转变为贝氏体+粒状贝氏体+少量铁素体;将其冲击断口做电子扫描电镜分析,结果表明整个断口主要为放射区,只有少量纤维区和剪切唇区主要呈解理特征;验证了调整双丝间距和焊速得到合理的热循环是取得优良焊接接头的保证。
