P2P网贷平台的主要风险及防范策略

P2P是我国互联网金融的重要形式之一,近几年在国内呈现出如火如荼的发展之势,它一方面为散户投资提供了可行渠道,为个人和小微企业融资提供了便利途径,另一方面也暴露出越来越多的潜在风险,其逐渐危及行业发展和市场稳定。笔者首先介绍P2P的发展概况,指出问题研究的必要性;其次通过分析国内P2P的具体法律关系和本土特征,揭示其在信用上、操作上、流动性和法律方面的各项风险;最后对比美国监管模式,认为我国P2P更适合作为中介平台纳入监管,应在监管主体、市场准入、持续经营、资金管理和市场退出方面加以规范,并辅之征信体系建设和行业自律的强化。     

酸性蚀刻废液中铜的形态分布及电化学行为

在氯化物体系中,Cu^＋、Cu^2＋均能与Cl^-形成多种形态的配合物,存在形态及分布与溶液中各离子浓度有关。由于各种配合物的稳定性不同,致使Cu^＋、Cu^2＋氯化物的溶解度及电极电位也不同。对酸性蚀刻废液中铜的存在形态、电化学行为、以及采用隔膜电解法回收工艺的可行性进行了分析。     

One Monopoly Is Better Than Two: Antitrust Policy and Microsoft

The Department of Justice recent case against Microsoft is that it should not be allowed to aggressively maintain control over the internet browser market with the objective of preventing the internet from becoming the platform that could ultimately destroy Microsoft's operating system market. The aim of this paper is not to attack the Department of Justice case. Rather, it is to argue that for consumers one monopoly dominating both the operating system and applications is better than two separate monopolies. In our model we integrate Cournot's theory of two goods that are jointly used in the production of a third composite good with the fixed-proportion model. Utilizing our model we develop a possible explanation for Microsoft's actions – protection of its monopoly profits in the operating systems package market. Additionally we show that the price of the final product is lower if one firm monopolizes all markets. Consequently, the ordered split-up of Microsoft by Judge Thomas P. Jackson, aiming at creating two separate companies, one that will produce the windows and the other the operating systems, will harm consumers.     

预制可分离式电缆接头电位分布分析与绝缘设计

文章基于预制可分离式电缆接头的复合结构和材料特征,分析了工频条件下胶质接头的界面特性和电场畸变。采用等效电路法,讨论了半导电屏蔽层和电场应力锥改善电缆附件装配连接界面电位梯度分布的作用机理。结果表明,内屏蔽层能消除局部电场集中,使介质表面的电位分布均匀,提高电缆附件的工频耐压和局放电压;适当减小外表面电阻率,能有效抑制沿面放电;应力锥可改变电缆屏蔽端部电容链结构路径,可减小容抗值降低电位,解决电缆屏蔽层断开处轴向电场过强问题。     

贸易引力模型对中国新疆与中亚四国贸易流量的实证检验及出口潜力分析

文章采用2005年中国新疆及哈萨克斯坦、吉尔吉斯斯坦、土库曼斯坦、塔吉克斯坦四个国家的出口贸易流量的截面数据,通过贸易引力模型进行实证检验。实证表明：GDP、空间距离以及上海合作组织这三个因素对上述国家和地区间的双边贸易具有明显的影响。文章通过实际双边贸易额与模型预测贸易额的比较,对上述国家和地区间双边贸易发展潜力进行分析和估计。     

PRICING EQUITY DERIVATIVES SUBJECT TO BANKRUPTCY

We solve in closed form a parsimonious extension of the Black–Scholes–Merton model with bankruptcy where the hazard rate of bankruptcy is a negative power of the stock price. Combining a scale change and a measure change, the model dynamics is reduced to a linear stochastic differential equation whose solution is a diffusion process that plays a central role in the pricing of Asian options. The solution is in the form of a spectral expansion associated with the diffusion infinitesimal generator. The latter is closely related to the Schrödinger operator with Morse potential. Pricing formulas for both corporate bonds and stock options are obtained in closed form. Term credit spreads on corporate bonds and implied volatility skews of stock options are closely linked in this model, with parameters of the hazard rate specification controlling both the shape of the term structure of credit spreads and the slope of the implied volatility skew. Our analytical formulas are easy to implement and should prove useful to researchers and practitioners in corporate debt and equity derivatives markets.

Evaluating the Tourism Potential of Public Museums in Hangzhou: A Supply-Side Perspective

This is a qualitative study to evaluate the tourism potential of public museums from a supply-side perspective. Nine specialized public museums in Hangzhou were evaluated based on six criteria: cultural, physical, product, experiential, marketing, and leadership. The overall tourism potential was rated as moderate for the museums in Hangzhou. Poor accessibility, isolation from tourism nodes, lack of complementarity with peripheral attractions, and limited carrying capacity impair the museums' appeal to tourists. The local government's proactive intention to develop cultural tourism and the innovative marketing efforts adopted by a few museums certainly help to enhance the museums' tourism potential.
