数据确权的理论逻辑与路径设计

我国"数据战略"有效实施的前提之一即是数据确权与交易,数据财产权的产生,与人的劳动物化其中有着因果关系.本文试图以马克思劳动价值论证明数据这一新生产要素的产权来源及其归属与物化劳动的相关性,并从社会契约集合的公意论述了大多数社会成员对财产权利安排的共同承认,然后讨论了以国家赋权的方式来塑形和定格数据财产权法律创制.最后提出:适用法律选择、数据权属分层、应用机制创新,构成了数据确权路径设计的主要内容.     

中国城市科技人才集聚促进了全要素生产率增长吗——来自285个地级市的经验研究

基于2005—2018年中国内地285个地级市数据，对城市科技人才集聚与全要素生产率（简称“TFP”）进行测度分析，实证考察科技人才集聚对TFP的影响。结果表明：①城市科技人才集聚与TFP空间分异特征显著，但二者具有较强的时空一致性，即科技人才集聚特征显著的城市，其TFP也相对稳定；②城市科技人才集聚对TFP的影响呈倒U型，但研究期内大多数城市仍处于集聚效应占主导阶段,科技人才集聚通过提升城市技术进步水平促进TFP增长，而科技人才集聚对技术效率的影响呈倒U型；③不同类型城市科技人才集聚对其TFP影响的异质性显著，且适宜集聚区间也存在差异。省会城市及一、二线城市等优势特征显著的城市所能承受的科技人才集聚规模上限更高，有利于通过释放集聚红利促进TFP增长，而非省会城市、三线及以下城市等则拐点值较低。     

数字经济对区域创新绩效及其空间溢出效应的影响

数字化时代的经济运行方式呈现出数据驱动、万物互联、创新迭代的特征，数字经济的数字化、网络化、智能化属性对创新活动产生了深刻影响。运用空间杜宾模型，对361座城市2010-2018年度数据进行实证检验。检验结果表明，数字经济发展不仅能够带动本地创新绩效提升，而且对周边城市创新绩效也具有显著正向影响；与中、西部地区相比，东部地区数字经济对创新绩效的促进作用更强，空间溢出效应也更显著。由此，建议可从挖掘数据要素价值、搭建数字化平台、推动数字技术创新等角度发展数字经济，促进本地区和周边地区创新绩效共同提升。     

The Benefit of Frequent Corporate Philanthropy

Applying behavioural economic theory, we argue that the frequency of philanthropic activity is important in determining corporate philanthropy's economic outcome. Using Chinese data from 2003 to 2016, we find that firms with more frequent philanthropic activities obtain more government subsidies than firms that only engage in one-off charitable donations. Firms with better corporate governance, such as higher management ownership and more independent directors, are more likely to adopt a strategy of frequent donation. Furthermore, firms are more likely to be frequent donors when management or local government officers have a long tenure. Our findings provide insight into the giving process and suggest that firms can maximize the benefit of corporate philanthropy if they strategically consider the donation frequency and donation amount simultaneously.     

Chief Audit Executive as Supervisory Board Member and Executive Compensation Contracts

This paper studies a unique phenomenon in China's corporate governance—that chief audit executives (CAEs) sit on supervisory boards (CAE duality)—and examines its effects on executive compensation contracts. Using a sample of listed firms between 2010 and 2018, we find a significant positive relation between CAE duality and pay-for-performance sensitivity, which suggests that the dual position helps integrate monitoring resources and reduces agency costs. This positive relation is more pronounced when companies face a stricter monitoring environment and in non-state-owned enterprises (non-SOEs) than in SOEs. In addition, we find that the recent reforms on compensation strengthen the role of CAE duality in SOEs. Further analysis identifies the reliability of performance information (i.e., earnings quality) and reduced executive self-interested behaviours (i.e., perquisite consumption) as the influencing mechanisms that increase the demand for performance-based compensation and thus improve pay-for-performance sensitivity.     

团队科学创造力的提升需重视团队成就目标导向——被调节的中介效应

基于创造力成分等多维理论，构建以团队反馈寻求行为为中介变量，团队凝聚力为调节变量的被调节的中介效应模型，以期深入解释创新团队成就目标导向如何影响其团队科学创造力。基于129个理工科大学生科技创新团队数据，研究结果表明，团队学习目标导向和团队表现目标导向分别与团队科学创造力有显著的正向和负向关系；团队反馈寻求行为在团队成就目标导向与团队科学创造力间起部分中介作用；团队凝聚力负向调节团队反馈寻求行为与团队科学创造力间的关系，并弱化了团队成就目标导向通过团队反馈寻求行为对团队科学创造力的间接影响。结论对提高科技创新团队科学创造力有一定指导价值。     

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.     

违约与杠杆周期——一个带有救助的金融加速器模型

我国为应对2008年国际金融危机的冲击采取了一系列经济刺激政策,在发挥“稳增长”作用的同时,也在一定程度上导致我国企业部门杠杆水平快速上升,但与此同时,不良贷款率并没有随企业部门杠杆的上升而显著增加。为了解释企业部门违约与杠杆的周期特征,本文在金融加速器模型(Bernanke et al.,1999)基础上,引入政府对企业部门的违约救助机制,建立DSGE模型进行讨论。进一步地,本文还通过一个不合意的去杠杆政策试验表明,忽略资产价格稳定(或者说金融稳定)前提下的去杠杆政策,反而会使企业部门的杠杆和违约率同时上升到一个较高水平。最后,引入一个盯住预期资产价格的动态救助规则能够发挥稳定经济的作用,并提高社会福利水平。
