对实体经济与虚拟资产回报率关系的研究综述

实体经济和虚拟资产之间回报率关系具有深刻的经济学含义和政策意义。对于实体经济和虚拟资产回报率之间的显著偏离，研究认为，虚拟资产的膨胀根植于实体经济的周期性萧条。然而，对虚拟资产价值的信心仍是建立在其随时可以转换为物质财富基础之上的。货币政策应该充分关注相关的资产价格，应努力研究金融发展和经济回报率偏离的关键因素。

The role of Chinese stock market in global stock markets: A safe haven or a hedge?

The contribution of the study is threefold. First, the paper proposes a new empirically testable definition for a safe haven and a hedge from the viewpoint of extreme and regular dependences measured by a modern statistical tool of copulas. Second, this paper investigates the extreme and regular dependences between the Chinese and the G7 stock markets, using a mixture copula specification, and the results reveal that the Chinese stock market has been not only a hedge but also a safe haven for the G7 stock markets all these years. Finally, this study suggests that the Chinese stock market is the target market for global stock fund managers and international investors, who are seeking a hedge or a safe haven for their portfolios, under turbulence.

公共危机信息管理过程研究——以河南“钻60事件”为例

公共危机管理中信息管理是关键，如果处置不当，容易造成危机的扩大化，将会给人民财产带来巨大损失和国家安全的不稳定。因此，加强危机管理，尤其是加强对危机信息过程的有效管理便成为处在现代化发展关键时期所要认真思考的一项重大的理论与实践课题。河南“钴60事件”的信患管理过程再次给我们敲响警钟：从其信息封锁、信患无序、信息纠正、信患对称四个方面实证研究来看。我国在公共信息管理方面存在很大不足。我国公共危机信息管理过程须从信息公开、建立信息管理体系、媒体利用、信息资源共享等几个方面进行优化。     

Quality improvement in competing supply chains

In this study, we consider quality improvement in a given segment of the market, shared by two supplier-manufacturer supply chains which offer a given product at the same price but compete on quality. The mechanism on the selection of supply chain structures and quality improvement strategies of the two supply chains is described. In particular, we analyze three possible structure combinations: two integrated supply chains, two decentralized supply chains, and one integrated and one decentralized supply chains. Between the supply chains, Nash's non-cooperative game is implemented. Numerical experiments illustrate the mechanism and some related issues are discussed.
