长期以来,商业银行尤其是大银行拓展中小企业信贷市场一直面临困境。但中国工商银行青岛分行却以中小企业商品交易为基础,较为成功地开发了一系列贸易融资产品。由此可以看出,在特定的产品、制度和技术保证下,大银行也可以成为中小企业信贷市场上的有效资金供给者。 相似文献

This study attempts to examine the presence of herding behavior in the Pakistan Stock Exchange (PSX). The novel contribution of this paper is that it investigates the herding phenomenon from a large number of facets such as herding of firms towards market, herding of firms towards industry portfolios, herding of industry portfolios towards market, herding in mostly traded stocks and in large and small stocks, and herding in the crisis period. For this purpose, we use the herding behavior model of Christie and Huang (1995) on the daily closing prices data of 609 firms listed on the PSX from January 2004 to December 2013. Results show that individual firms do not herd towards market index, except when the market experiences a negative return of 5%. However, when we sort firms into small and large groups based on median market capitalization, results indicate that large firms show herding behavior in extreme market movements. Further, we find that firms in several industries herd towards their industry portfolios. However, we find weak evidence of industry portfolios herding towards the market. We also segregate the impact of financial crisis of 2008 from normal times. These findings support results of our baseline estimation. 相似文献

运用大涡模拟计算了两个非对称复式断面明渠内的水流运动和污染物扩散,其中由亚格子尺度涡运动引起的亚格子应力与物质扩散通过Smagorinsky-Lilly亚网格模型模拟。预测结果与Shiono等使用激光多普勒流速计(LDA)和激光诱导荧光技术(LIF)测量的实验数据进行了对比,计算得到的流场结构和污染物浓度分布均较好地吻合于测量结果。成功地再现了在其中一个复式断面明渠中观测到的横向浓度分布呈现显著双峰值的现象,根据计算的流场得出复式断面明渠中流向交替变化的强烈横向流动是产生这种现象的主要原因。 相似文献

A good friend of China,who from ASEAN countries,once said that"The biggest difference of China between her past and present is that China is rich now with large foreign exchange reserves in the bags"Yes,the Chinese government is encouraging his enterprises to go abroad by various means.Facilitating Chinese enterprises to invest globally is in accordance with China's present Go Global Strategy exactly.And The 2nd Chinese Enterprises Outbound Investment Conference (CEOIC), co-hosted by China Council for the Promotion of International Trade (CCPIT) and Ministry of Commerce of China is a good example to that. 相似文献

Artificial structures have been used to potentially increase fish production by providing cover, feeding and spawning areas. In some rivers, the United States Army Corps of Engineers has constructed dikes to provide additional habitat for river fishes and to mitigate for navigation impacts to young fishes. This study was designed to test whether such structures function as viable habitats as evidenced by increased abundances relative to reference areas lacking artificial dike structures. Dikes and reference sites in the Kanawha River, West Virginia were sampled 21 times between July 2002 and October 2003. We found a difference in taxonomic composition among fish using dikes relative to reference areas. Artificial dike structure use was most important among Centrarchidae species, especially juveniles, including black bass and several species of Lepomis. Further, distribution of fish between areas with and without dikes appears most affected by water temperature in 2002 and by short‐term river flow in 2003. These patterns suggest these artificial structures are viable mitigation measures that target and benefit fish of economic interest. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献
