构建和谐财务管理目标的思考

构建和谐社会是现今中国的重要社会问题。在财务管理学中,财务目标是财务决策的准绳、财务行为的依据、理财绩效的考核标准。本文从和谐概念出发,从财务管理的角度,运用产权理论和契约理论分析财务管理目标和谐的现实性选择和构建。     

西方金融创新理论述评

西方对金融创新首先提出理论解释的是约束引致假说和管制理论。约束引致假说认为金融创新是银行试图降低与特定资产负债表约束关联的成本。管制理论认为金融创新是管制者和被管制者之间持续的斗争。不完全市场理论认为新金融产品仅仅是金融工具特定因素组合的变化。证券设计和不完全市场模型是以一般均衡理论对金融创新过程模型化。目前尚无金融创新普遍认可和统一的理论。     

Does the Euro–Mediterranean Partnership contribute to regional integration?

The paper investigates whether Southern Mediterranean and Middle Eastern markets under the Euro–Mediterranean Partnership (Egypt, Lebanon, Morocco, Malta, and Turkey) have become more financially integrated with the European stock market over time. The findings suggest that the Turkish equity market is moderately integrated with the European market, while the other economies exhibit weak financial integration with Europe, supporting the idea that the partnership appears to have no effect on enhancing inter-market linkages for these economies. Therefore, these markets would be good destinations for international investors seeking attractive investment opportunities to diversify their equity portfolios. Structural changes in the cross-market integration do exist, which may be considered as a guide for international equity portfolio diversification over different subperiods. In addition, there is evidence of an increasing trend in conditional correlations for Egypt and Turkey, to varying degrees, over time, notably during the post global financial crisis of 2007–2008, thus revealing herding behavior during this period. Overall, investors should be wary of the variation of equity market integration over time before engaging in an investment at the level of portfolio management and diversification. Policymakers must be aware of the remoteness of the current achievements of the Euro–Mediterranean Partnership from the targets set in terms of financial development and economic growth.     

基于时频分析的裂纹转子碰摩故障特征研究

为研究转子系统耦合故障特性,采用有限元方法建立了含有横向裂纹、转静碰摩的非线性转子动力学模型。首先研究了不同转速下裂纹、碰摩单一故障下转子系统的振动响应,其次研究了两种故障耦合情况下系统的振动响应特征。采用波形图、FFT谱图、瞬时频率和Hilbert-Huang时频谱(HHS)相结合的方法对故障转子振动信号进行了分析。分析结果表明:运用多种时频分析相结合的方法可以较为全面地了解转子的故障特征,裂纹转子在1/5、1/3临界转速时会发生较为明显的5X、3X谐波,且裂纹的产生会导致响应幅值增大,从而引起更为严重的碰摩。      

金融发展与经济波动的联系:一个文献综述

从金融发展视角研究经济波动属于一个前沿主题。本文归纳了金融发展与经济波动发生联系的理论机制,并对国内外经验文献进行了梳理。总的来看,理论研究与经验研究都未形成一致的结论,因此有关金融发展与经济波动联系的研究仍然是一个有待进一步探索的开放领域。     

Markets or networks: Households’ choice of financial intermediary in Western China

We argue that households’ choice of financial intermediary is conditioned by households’ social network structures and socioeconomic status. Analyses show that households’ social network size and network composition affect their choices by limiting the quality and quantity of information, resources, and social influence one can access through social ties. Moreover, we find that high-SES families favor formal intermediaries due not only to their richer financial knowledge, higher affordability, and greater capacity to repay loans, but also to their high demands and special types of financial needs that can hardly be satisfied by embedded resources.     

从第三方支付发展看上海国际金融中心建设

互联网时代第三方支付的发展,揭示了企业"控制用户信息流以控制支付流,控制支付流以控制资金流;获得用户网络接入权胜过获得资本所有权,获得数据投入量胜过获得资金投入量"的新规则。大平台日益成为金融机构控制用户信息流、获得用户网络接入权的重要载体,在平台组合上加载信用有关数据流日益成为形成金融机构风险管理能力的重要生产资料。在互联网时代推进上海国际金融中心建设,既要继续重视金融机构集聚,更要注重鼓励企业赢得全国性用户网络接入权,加强平台组合,增强信用数据流。上海应依托自贸试验区推进互联网金融监管创新;牵头建立长三角征信联盟集团公司;搭建本地金融机构网聚平台。     

Coordinating contracts for a financially constrained supply chain

We consider a financially constrained supply chain in which a supplier (leader) sells products to a retailer (follower) who has no access to bank financing due to her low credit rating. However, the supplier can borrow from a bank and offer trade credit to the retailer to alleviate her financial constraint. Failure to pay off a bank loan or trade credit incurs a variable default cost. We analyze the centralized version of the supply chain to obtain new coordination requirements. We then examine whether revenue-sharing, buyback, and all-unit quantity discount contracts can coordinate our supply chain. We show that the all-unit quantity discount contract fails to coordinate. However, the revenue-sharing and buyback contracts can coordinate the supply chain, but only when the supply chain has a sufficient total working capital. Moreover, they cannot allocate profit flexibly unless the supplier has a large enough working capital. Finally, we design a generalized revenue-sharing contract that coordinates the supply chain with flexible profit allocation, and also show by numerical examples its superiority over the revenue-sharing and buyback contracts.

女大学生心理亚健康状态的诊断与辅导

世界卫生组织的一项全球性调查结果显示,全世界真正健康者仅占人口总数的5％;有75％是“亚健康”者,年龄多在20-45岁。聚类分析结果表明,女大学生中心理正常的只有37．6％,而处于边缘状态的女生却超过了半数,表明50％以上的女大学生处于心理亚健康状态。心理学工作者只有通过心理测量来筛查、心理亚健康状态的表征、个别访谈等方法诊断出处于心理亚健康状态的女大学生,才能帮助女大学生及时觉察并正确认知心理亚健康状态．掌握有效的调适方法,摆脱亚心理健康．形成健康的心理。
