城市轨道交通大小交路结合快慢车开行方案优化

城市轨道交通线路可以实行大小交路的开行模式,以克服断面客流不均衡导致的能力浪费,而这种模式使长距离乘客的出行时间增加,可以在列车开行大小交路的基础上考虑开行快慢车。以乘客出行成本与企业运营成本最小为目标,考虑列车停站时间与客流需求的关系,将停站时间纳入乘客出行成本,建立双目标非线性整数优化模型,求解乘客与运营企业的成本博弈均衡点。通过算例验证模型的有效性,结果表明,相对于大小交路嵌套的运营模式,实行"大小交路+快慢车"的运营模式可以有效降低乘客出行成本与企业运营成本。

数字金融、银行信贷渠道与货币政策传导

作为新兴金融业态,数字金融发展会对既有金融体系带来怎样的冲击和影响?聚焦于货币政策传导机制这一宏观命题,立足于我国以银行信贷渠道为主导的数量型中介,运用我国商业银行、A股上市公司的微观面板数据,本文深度剖析了数字金融发展与货币政策银行信贷渠道传导之间的内在联系和影响机理。研究发现:(1)数字金融发展显著弱化了货币政策银行信贷渠道的传导效应,采用工具变量法克服内生性和控制影子银行变量等一系列稳健性检验后的结果依然支持该结论。(2)具体而言,数字金融削弱银行信贷渠道传导效果是通过改变银行资产负债结构和弱化实体企业对银行贷款的依赖而实现的。(3)上述弱化效应在以城市和农村商业银行为主的中小型金融机构以及低资本、低流动性和低报酬的银行中尤为突出。     

CEO organizational identification and firm cash holdings

As the decision-makers and implementers of a firm’s financial strategy, executives play a critical role in cash holding activities, and their psychological characteristics have a major impact on cash holdings. This paper investigates the association between CEO organizational identification and firm cash holdings. The empirical results show that CEO organizational identification is negatively associated with firm cash holdings, and the negative association is more pronounced when the level of financial development is higher and economic uncertainty is lower. Further analysis reveals that the higher a CEO’s organizational identification, the higher the firm’s R&D investment and capital expenditure, and high CEO organizational identification can increase the value of firm cash holdings. Overall, our findings supplement the literature on organizational identification and cash holdings, and on the effect of executives’ psychological characteristics on corporate financial decision-making.     

Complex Network of Aviation E-Services in the Belt and Road Initiative: A Heuristic Study of Small Data based on Block Modeling

ABSTRACT

The aviation e-service system is an important part of support for business communication in regions covered by Belt and Road initiative. In exploring the role of airline companies in this system, we examine the structure of the network, which consists of airlines interconnections based on small data of individual attributes of aviation companies in aviation e-services, and study these interconnections across different groups using block modeling. The heuristic solution of airline companies in development of international communication and cooperation is further discussed. Among our policy implications for global managers, we suggest the enhancement of cross-regional cooperation among airlines.

进一步提高Shibor报价的可交易性

Shibor自正式运行以来已经对中国的利率市场化改革产生了积极而深远的影响。结合国外经验和国内现状,文章认为,在Shibor培育过程中提高报价的可交易性是Shibor能否真正成为利率基准的根本所在。目前,Shibor短端报价的可交易性已得到了市场的认可,文章从扩大以Shibor为基准的回购交易、拓宽Shibor报价行多元性等方面就提高中长端Shibor可交易性提出建议。     

我国商业银行风险容忍度研究

风险容忍度是国际活跃大银行普遍采用的一种风险控制手段,通常表现为股东大会或董事会对企业经营管理层所提出的经营稳健性要求,其目的在于维护企业经营的安全性与盈利性之间的一种平衡。在我国现有的公司治理结构下,这种风险容忍度的实施显然不能直接效仿国外的通行做法。因此,本文旨在从我国现有的公司治理结构特点出发,对银行的风险容忍度实施进行研究,力图建立适合我国银行实际情况的风险容忍度实施流程规划,为维护我国银行经营的安全性和稳定性做出贡献。     

Religion,the Nature of Ultimate Owner,and Corporate Philanthropic Giving: Evidence from China

Using a sample of Chinese listed firms for the period of 2004–2010, this study examines the impact of religion on corporate philanthropic giving. Based on hand-collected data of religion and corporate philanthropic giving, we provide strong and robust evidence that religion is significantly positively associated with Chinese listed firms’ philanthropic giving. This finding is consistent with the view that religiosity has remarkable effects on individual thinking and behavior, and can serve as social norms to influence corporate philanthropy. Moreover, religion and corporate philanthropic giving have a significantly weaker (less pronounced) positive association for state-owned enterprises than for non-state-owned enterprises. The results are robust to a variety of sensitivity tests. Our results highlight religious influence on corporate philanthropic giving in contemporary China, an old traditional country with a typical communist economy.
