Bank size, market concentration, and bank earnings volatility in the US

We examine whether bank earnings volatility depends on bank size and the degree of concentration in the banking sector. Using quarterly data for non-investment banks in the United States for the period 2004Q1-2009Q4 and controlling for the quality of management, leverage, and diversification, we find that bank size reduces return volatility. The negative impact of bank size on bank earnings volatility decreases (in absolute terms) with market concentration. We also find that larger banks located in concentrated markets have experienced higher volatility during the recent financial crisis.     

会计师事务所合并行为及对我国审计市场结构的影响

2006年以来,我国会计师事务所出现了新一轮的合并高潮,合并成为当前会计师事务所实现规模扩张、做大做强的重要途径。本文在深入分析我国本土事务所合并的内部及外部动因的基础上,结合相关数据对合并给我国审计市场结构带来的影响进行了研究,发现我国本土事务所的市场份额逐年稳步增加、发展势头迅猛,虽然审计市场整体结构仍然保持着寡占型特点,但是市场内部竞争非常激烈。因此,本土事务所在合并做大的过程中更要注意做强,积极探索积累行业专长,形成自己的核心竞争能力。     

中非贸易发展现状分析

中非贸易经过半个世纪的发展,近年以40%左右的增速呈现快速上升的趋势。同时,中国与非洲的贸易占各自对外贸易总额低、中国与各个非洲国家和地区的贸易水平不均衡、进出口结构单一的等问题也不容忽视。通过从世界贸易组织发布的《国际贸易统计年鉴(2009)》和国家统计网得到的权威数据数据,从总体贸易水平、进出口结构、贸易集中度等方面对中非贸易进行分析,揭示了中非贸易的现状及发展趋势,并找出与中国贸易往来最密切的非洲国家,可作为后续研究的重点关注对象。     

环渤海地区制造业专业化程度的实证研究

通过计算分析了2000-2009年环渤海地区三省两市20个制造业部门的Hovver专业化系数和Krugman专业化指数,结果表明环渤海地区制造业专业化程度在2002-2005年经历了一次调整,调整的原因主要是由于环渤海地区间的产业结构的调整;三省两市之间制造业结构的差异从2006年以后趋于稳定,且各地区专业化程度分成三个梯度。市场机制在资源配置过程中的作用越来越强,三省两市按照自身优势发展制造业的趋势也越来越明显。     

制造业集聚趋势的实证分析——以广东省为例

在经济全球化和区域一体化背景下,广东经济的持续竞争力在很大程度上来源于产业集聚的规模经济优势,尤其是珠三角地区的集聚经济优势一直成为该地区吸引外商投资和国内配套产业跟进的重要动因。本文在分析广东区域经济发展特点和制造业结构调整特征的基础上,应用区位熵指数、空间基尼系数和集中率指数等分析工具,详细研究了广东制造业的比较优势与集聚规模、地理集聚程度与变化动态以及空间分布水平与转移趋势,对不同类型行业的集聚程度和变化趋势进行了深入分析,相关结论对于当前制定推动产业结构调整和建设现代产业体系的政策具有重要的参考价值。     

中国盒融产业集聚水平测度

本文利用区位基尼系数、区位熵指数、CR5指数埘中国金融产业2001-2010年的集聚水平进行了测度。结果表明,金融业具有较为明显的集聚特征,且总体集聚程度不断增强,金融资源主要集中在于东部地区,其中北京、上海的金融集聚程度最高,而中两部地区金融集聚程度较低,在今后的发展过程中应注重金融中心的辐射效应,     

Becoming a preferred customer one step at a time

A preferred customer is a buying organization who receives better treatment than other customers from a supplier, in terms of product quality and availability, support in the sourcing process, delivery or/and prices. The decision to become a preferred customer implies a continuous commitment by the purchaser to a complex, expensive and often uncertain process. It is important to use a strategic approach, as well as appropriate tactics. Based on well-known models on the development of buyer-supplier relationship, on customer portfolio analysis and on the emergent literature in customer attractiveness and preferred customer status, we suggest four steps to become – and remain – a preferred customer: initial attraction, performance, engagement and sustainability. The process takes the perspective of a buyer willing to obtain the preferential status and focuses on the strategies and tactics that could influence the supplier's decision of granting this status. The proposed process considers that the supplier is continuously comparing the value offered by the customer to its expectations, and to the value offered by other customer relationships.     

The effect of buyer behaviors on preferred customer status and access to supplier technological innovation: An empirical study of supplier perceptions

Buying firms are increasingly looking to suppliers for technological innovations that enhance the competitive position of their new products. However, extant research provides limited guidance on how buying firms may gain access to suppliers' innovative technologies. To address this gap in the literature, we draw from social exchange theory to posit sequential relationships among buyer behaviors, preferred customer status, and supplier's willingness to share technological innovations. We test our assertions by applying structural equation modeling statistical analyses to survey response data from 233 sales personnel of production good suppliers in the U.S. automotive industry. Whereas our results show that two buyer behaviors – early supplier involvement and relational reliability – positively affect preferred customer status, a third behavior – share of sales – has no effect. In turn, we find that preferred customer status is positively associated with supplier's willingness to share new technology with the buyer. Further, our findings indicate that preferred customer status fully mediates the benefits exchanged within a buyer–supplier relationship. Hence, our study highlights why buyers seeking innovations should take care that their behavior is appropriate for managing suppliers' perceptions. Accordingly, our results provide specific guidance to buyers as to how they may increase their access to suppliers' new technologies.     

中国区域旅游产业结构变化的空间差异分析

利用区位熵、产业集中度指数和产业结构变化指数以及产业结构变化方向四个理论模型,以2000—2009年旅游产业统计数据基础,分析了我国不同区域旅游核心产业之间的变化及差异。结果表明：旅游核心产业的区位熵总体呈现出东高西低的梯度递减格局,其中旅行社业的区域特征最为明显。从多年的发展趋势来看,我国旅游产业的区位熵总体呈现出区域均衡化发展的趋势;产业集中度指数方面区域特征相对较弱,但总体向酒店行业集中。发展趋势方面,总体呈现出逐年降低的趋势,说明我国旅游产业间的空间差异也在向均衡化发展;产业结构变化指数近年来发展趋势相对平缓,空间方面总体呈现出北大南小,东、西部变化大,中部小的格局;产业结构变化方向有一定差异,但较为一致,总体表现为旅游景区业和旅行社业上升,旅游星级饭店业下降的趋势。     

我国集装箱港口体系演进规律研究

从集装箱港口数量、吞吐量、空间布局、市场集中度几个角度,利用赫芬达尔—赫希曼指数来分析1979—2011年我国集装箱港口体系及市场结构的演变,指出1979—1989年是快速分散阶段,为高度集中的寡占市场;1989—2009年是缓慢分散和缓慢集中相互更替的发展阶段,形成了中度集中的寡占市场;2010—2011年延续了分散的趋势,HHI值已经小于1 000,出现了形成非集中竞争市场的趋势。这要求港口企业随着竞争程度的不断增强,需要不断提升质量、建设软环境,提高竞争力,从粗放式发展向精细化、敏捷化发展。
