后金融危机时期中国货币政策选择——基于美国QE2经济后果的分析

"二次量化宽松政策"(简称QE2)是美联储在国内经济提振乏力、失业率居高不下以及世界经济复苏不平衡的背景下启动的。QE2或许能够使美国走出通缩的泥潭,也有可能催生资产泡沫,酝酿新的金融危机,但却无疑给世界经济,尤其是新兴市场国家的经济继续复苏蒙上了一层阴影,全球热钱将更加泛滥,世界经济秩序将遭到破坏,各国外汇储备将进一步缩水等。对此,我国中央银行货币政策必须加强与财政政策的配合,适时调整外汇储备资产结构,扩大本币结算合作,积极应对QE2的挑战。     

Examining Public Hospital Service Failure: The Influence of Service Failure Type,Service Expectations,and Attribution on Consumer Response

This study investigates three independent variables; types of service failure, service expectations, and attribution on postfailure responses in healthcare. A between-subjects 3?×?2?×?2 experimental design using written scenarios was used. The findings demonstrate that customer responses to service failures in hospitals are extensively influenced by the type of service failure, the level of service expectation of the provider, and, to a lesser extent, the controllability of the cause of the failure. Core service failures lead to greater increases in negative responses for satisfaction, emotional, and behavioral responses than supplementary service failure with high service expectations protecting the provider against overall dissatisfaction, negative word-of-mouth, and switching behaviors. Interestingly, perceived high controllability leads to greater dissatisfaction but not to increased negative emotional or behavioral responses. The study applies attribution theory to explain the results. The article concludes with managerial implications.

The Relationship between the Firm Size and the Quantity of Accountants Employed by the Firm： An Analysis of the 436 Listed Firms in the Chinese Shenzhen Stock Exchange

There are 9.56 million accountants in China, who are working in different size firms and nonprofit organizations. The objective of this article is to examine the quantitative relationship between the firm size and the quantity of accountants working for the firm. In this paper, the employees, sales revenues, and total assets in a firm are employed to measure firm size. The authors collect and analyze the data of 436 listed firms from the Chinese Shenzhen Stock Exchange. The result of this study indicates there is a positive relationship between the firm size and the quantity of accountants employed by the firm. The study also establishes the multiple regression equation, which can be used to predict the quantity of accountants of listed firms. And it provides a way to predict the quantity of accountants of legal organizations.

美国第二轮量化宽松货币政策的影响及中国对策

美联储第二轮量化宽松货币政策预计对美国经济的刺激作用有限,并会对其他国家特别是新兴市场带来较严重的负面溢出效应。其中,美元泛滥可能引发较为严重的通货膨胀,并刺激贸易保护主义抬头。中国需要采取＂堵疏结合、攻防有序＂的手段,严格监控风险度高的短期流动资金,将长期资金流入有效疏导到金融短板加以利用,力保经济平稳较快发展。同时,应加强与国际社会的协作,对美国量化宽松政策形成一定的制约。
