中国“一带一路”战略定位的三个问题

"一带一路"战略在大方向基本清晰的情况下,在战略定位上仍然存在着三个有待进一步厘清的问题,包括:"一带一路"是全球战略还是区域战略?"一带一路"应以多重双边伙伴关系为基础还是应以跨区域整合为基础?"一带一路"战略应以西北方向为优先还是应以东南方向为优先?对这三个问题的诠释对于"一带一路"战略的推进有着极为重要的意义。这一战略虽然表现出了一定的全球战略的特征,但在本质上还是区域性的;其的推进必须以多重双边伙伴关系为基础。就目前的具体政治形势与经济形势来看,"一带一路"战略开拓西北面临更大的不确定性。     

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.

案例教学法在金融学专业课程教学中的应用探析

案例教学法与传统的讲授式教学法在教师与学生的主体作用、传授知识的广度和深度、适用的学科领域以及教学情境等方面存在着明显差异.总体看来,案例教学法在激发师生“教”与“学”的积极性、知识传授的深度以及丰富的教学情境等方面具有相对优势,适合在以应用性为特点的部分金融学专业课程中进行实施.未来在金融学科应用案例教学法时需要在建立保障和推广案例教学的相关制度、丰富学科案例资源和形成一套标准化的案例教学流程等方面做进一步努力.     

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.
