跨界与企业创新关系研究：元分析发现与未来展望

跨界作为影响企业创新的重要因素，近年来备受关注，然而因缺乏统一的整合框架，两者关系研究结果呈现出差异性。为厘清两者关系，应用元分析法对86篇跨界与企业创新关系文献进行整合分析。结果表明，跨界与企业创新有较强的整体正相关性，但研究结果存在异质性。在研究层级方面，不同层级下两者关系存在显著差异。其中，在团队层级两者的相关度最高；在行业类别方面，不同行业类别下两者关系存在显著差异，其中，制造业企业跨界对企业创新的影响最显著；在文化情景方面，不同文化情景下两者关系存在显著差异，其中，中国文化情景下，跨界对企业创新的影响更显著。最后，就跨界与企业创新关系的空白点和未来方向进行了研究展望。     

Trade openness,FDI, and income inequality: Evidence from sub‐Saharan Africa

The motivation for this study stems from the United Nations Sustainable Development Goals (UN‐SDGs) and their impact by 2030. The UN highlights 17 SDGs that address pertinent local and global issues, one of which—SDG‐10—has been devoted to reducing inequality. This study investigates the nexus between trade openness, foreign direct investment (FDI), and income inequality in sub‐Saharan Africa using panel data from 2000 to 2015 and the generalized method of moment (GMM) technique approach. The findings show that FDI and income have a negative, statistically significant relationship with income inequality, signifying that as FDI and income per capita increase, the level of income inequality decreases. However, trade openness, education, political stability, corruption, and rule of law have a positive, statistically significant relationship with inequality. This study, therefore, offers some recommendations that will help policymakers. First, develop good policies to attract more foreign investors, which will contribute to creating employment opportunities in the region. Second, create more infrastructures to provide good quality education. Third, implement a good policy to motivate local production which will contribute to creating jobs. Fourth, build a strong institution(s) to fight against corruption.     

基于管理活动论的智能会计系统研究——从会计信息化到会计智能化

在智能化逐渐成为新一轮产业变革核心驱动力的背景下,会计管理活动的重心已经从簿记和报告转向价值管理与风险控制,会计信息系统作为会计在IT技术上的映射也面临着从信息化向智能化的转变.本文在回顾IT技术在会计中应用的三次浪潮基础上,以会计管理活动论为理论基础,结合大会计观和IT环境论,提出了智能会计系统的概念.并进一步基于软件工程方法学提出了智能会计系统的概念模型,构建了"决策—控制"价值增值循环、"披露—反馈"价值信息交换循环、"优化—共享"价值协同循环、"监督—调控"微观会计与宏观经济一体化管理循环四个智能会计系统业务循环模型,并从构建方法、物理结构和应用模式三个方面论述了智能会计系统的实现路径.本文的研究旨在构建智能会计系统的概念框架,推动智能会计系统构建理论和方法学上的创新,为智能化环境下会计的发展和实践提供思路.     

Board faultlines and the value of cash holdings: Evidence from Chinese listed companies

Faultlines can affect a board of director’s effectiveness in supervising senior managers, which in turn affects the value of a company’s cash holdings. Based on sample data from Chinese A-share listed companies from 2004 to 2016, we examine the relationship between board faultlines and the value of cash holdings. The empirical results indicate that board faultlines have a significant inhibitory effect on cash holding value. This inhibitory effect is stronger for board faultlines resulting from deep-level attributes. Furthermore, the inhibitory effect of board faultlines is stronger in state-owned enterprises (SOEs) than in non-SOEs. As an important governance mechanism, management shareholdings can reduce agency costs and mitigate the negative impact of board fissures on cash holdings. Overall, we enrich the literature on the economic consequences of board faultlines and their influence on cash holding value. We also offer companies practical suggestions for improving the supervisory mechanism of their board of directors.

Exploring how and when ethical conflict impairs employee organizational commitment: A stress perspective investigation

Previous studies demonstrate the detrimental effect of ethical conflict (i.e., incompatibility between ethical values of employees and organizations) on employee organizational commitment. However, few studies have assessed the underlying mechanisms and boundary conditions that may contribute to a deeper understanding of how and when the detrimental effect manifests. Drawing on the transactional model of stress and literature on the moral self, our study examines the psychological strain as a key intermediate mechanism that channels the negative relationship between the ethical conflict and organizational commitment. Furthermore, we posit that employees with different levels of moral identity and moral efficacy may suffer differently from ethical conflict. We tested our research model with two-wave lagged data obtained from 265 healthcare employees and found that the indirect, negative effect of ethical conflict on organizational commitment via psychological strain is strongest among employees with high moral identity and low moral efficacy. Interestingly, results show that employees with low moral identity and high moral efficacy do not suffer from ethical conflict. These findings suggest that ethical conflict is differentially harmful to employees and that a more nuanced understanding of its contingent effects is needed.     

上市公司股东不可撤销表决权委托研究——问题、挑战与监管

表决权是上市公司股东参与管理决策的重要方式。证券监管实践表明,不可撤销表决权委托既有规避股份限售和减持规则的动机,也有出于增强控制权转让交易中博弈弹性的考虑。表决权委托并非一项简单的债权债务法律关系,其合规性及对证券市场的影响需引起足够的重视。为规范上市公司股东不可撤销的表决权委托,本文建议:在信息披露监管方面,重点关注表决权委托对权益变动、控制权稳定性、投资者保护的影响;在制度规范方面,发布表决权委托示范协议指引等规则,明确表决权委托的关键要素和监管要求。
