企业社会责任对跨国并购绩效的影响——基于沪深A股上市企业的实证研究

为了帮助我国企业在跨国并购交易中更好地应对因企业社会责任表现所引起的跨国并购风险,平衡好经济利益诉求与社会责任的履行,论文以2009—2017年沪深A股上市公司109起成功的跨国并购事件为研究对象,基于利益相关者理论、社会契约理论与委托代理理论,研究了企业社会责任对于跨国并购绩效的影响,同时考虑了企业所有制、行业一致性和跨国并购经验的调节作用。采用多元回归模型的实证结果表明：1）企业社会责任对跨国并购绩效存在显著的正向影响;2）企业社会责任与跨国并购之间的正向关系受到国有属性与跨国并购经验的负向调节;3）当并购双方属于同一行业时,行业一致性会显著促进企业社会责任对跨国并购绩效的正向影响。建议企业主动披露企业社会责任履行状况并引入国际通行标准,也可借助国际公关公司制定企业社会责任战略。以上研究结论对中国企业履行社会责任方面具有一定的指导意义,同时也为跨国并购绩效的影响因素研究提供了新的理论视角。

从产权角度重新认识公有制的本质内涵与实现形式

作为生产资料所有制层面的产权是一个重要的范畴,它与生产资料所有制既有联系又有区别。从产权角度看,公有制的本质内涵就是要代表最广大人民群众的根本利益,实现公有资产所有权与经营权的分离,确保公有资本保值增值。现阶段,股份制应成为公有制的主要实现形式,而它本身并不就是公有制形式。

Institutional diversity and safe drinking water provision in the United States

In the United States, community water systems are not only numerous but also diverse. Nonetheless, operational scale and public versus private ownership have dominated the understanding of safe water access, leaving underexplored many other factors related to governance. Applying insights from the Institutional Analysis and Design literature, we create and analyze a dataset of California's water systems classified into 26 structural types associated with distinct governance institutions. We document differences in the number of Safe Drinking Water Act violations among these types and demonstrate their relevance for implementing solutions targeting non-compliance. Advancing equitable access necessitates greater attention to organizational structure and institutional diversity in drinking water provision.     

基于存储网关的数据安全去重方案

在实行客户端去重的云存储系统中,通过所有权证明可以解决攻击者仅凭借文件摘要获得整个文件的问题。然而,基于所有权证明的去重方案容易遭受侧信道攻击。攻击者通过上传文件来观察是否发生去重,即可判断该文件是否存在于云服务器中。基于存储网关提出一种改进的所有权证明去重方案,存储网关代替用户与云服务器进行交互,使得去重过程对用户透明,并采用流量混淆的方法抵抗侧信道攻击和关联文件攻击。分析与比较表明,该方案降低了客户端计算开销,并提高了安全性。     

Understanding patients’ trust toward community healthcare providers under different primary care settings in China: Impact of hospital ownership and registration mode

China is currently undertaking healthcare reform, and promoting general practitioner (GP) practice is a major improvement. The key to the success of the GP practice is whether or not patients are willing to accept and trust in GPs in community healthcare centers (CHCs). The objective of this study is to evaluate the impact of hospital ownership (public or private) and registration mode (registering with a CHC or a GP on patients’ trust in community health services. A user experiment was conducted, and 204 nonstudent participants were invited to finish simulated registration tasks in a self‐developed online registration system. Patients’ trust in CHCs, GPs, and GPs’ treatment outcomes was measured. The results indicated that patients had a significantly higher level of trust in private CHCs and private sector GPs, but they showed a higher level of trust in the treatment outcomes of public sector GPs due to the influence of their past medical experience seeing community doctors. The registration mode only influenced patients’ trust in GPs’ professional skills, that is, patients had a higher level of trust in GPs’ professional skills when registering with CHCs compared to registering with individual GPs.
