产业集聚与空间集聚的协调发展研究

自20世纪90年代以来,中国沿海地区出现了一批别具特色的产业集聚区,有力地推动了当地经济的快速发展。各地政府开始纷纷借鉴沿海地区经验,通过引导部分产业向该地区集聚以实现经济增长,带动城市化建设。探讨产业集聚与城市空间集聚之间是否协调发展,成为当前关注的焦点。文章阐述了产业集聚与空间集聚协调发展的内涵,并从理论上分析了两者间存在的促进机制和反馈机制。以中国制造业为例,实证分析了制造业产业集聚与城市空间集聚的关系,发现自1990年以来我国产业集聚和城市空间集聚之间呈现出一定的协调性,并在此基础上给出了相关政策建议。     

客户群体特征对企业创新绩效的影响研究——以中国制造业上市公司供应链为例

通常认为,供应链下游在地理空间上的集聚会促进信息交互和组织学习,强化核心企业的话语权,提升创新绩效。文章认为,在特定条件下,客户地理邻近也可能会拉低企业创新绩效,形成创新“空间锁定”困局。基于2009-2017年中国A股制造业上市公司及其供应链数据,考察客户地理邻近性对企业创新绩效的影响作用,并将客户集中度和客户属地多样性作为情境因素纳入研究框架。研究发现：客户地理邻近性与企业创新绩效呈倒U型关系,在一定阈值范围内客户地理邻近性拉升企业创新绩效,而超过该阈值客户地理邻近性抑制企业创新绩效;客户集中度对客户地理邻近性与企业创新绩效的关系不存在调节效应;客户属地多样性强化了客户地理邻近性与企业创新绩效的倒U型关系。以上结论从供应链视角揭示企业创新规律,对企业创新的内生机制研究形成了有益补充,有助于重新认识企业创新绩效的影响机制。     

Frequency and aircraft size dynamics in a concentrated growth market: The case of the Chinese domestic market

Despite the explosive growth of the Chinese aviation sector and the major industry reforms undertaken in recent decades, the Chinese domestic market remains highly concentrated with a significant element of regulation and governmental control in areas such as market entry and airline fleet planning. In this study, we investigate the frequency strategies and aircraft choices of airlines operating in this concentrated growth market. Our empirical investigation suggests that airlines mainly accommodate rapid traffic growth by flying more frequently, although increased aircraft size also contributes to market expansion. We also find a negative relationship between market concentration and flight frequency. Due to the more balanced market structure resulting from mergers among leading airlines since 2002, there has been a moderate reduction in market concentration at route level, contributing to a 3.7% increase in traffic volume from 2002 to 2008. The results of our study suggest that Chinese travelers have yet to fully enjoy the benefits of market liberalization, and airports should prioritize increasing capacity related to aircraft movements over the accommodation of larger aircraft.     

柯韦什的"虚荣心"与人的尊严--读凯尔泰斯小说《无命运的人生》

在纳粹集中营里，一个囚犯有没有维护自己尊严的可能？这是凯尔泰斯在小说《无命运的人生》中想回答的一个问题。作者通过对主人公柯韦什的“虚荣心”，及由此产生的一系列行为和心理活动的分析和描述，向我们表明：尽管在集中营过着非人的生活，忍受着极大的屈辱，主人公并未因此而放弃人的尊严。他一直在自觉不自觉地，用或明显或隐蔽的方式，来反抗野蛮暴力对人的尊严的取缔。     

Geographic concentration and vertical disintegration: Evidence from China

Existing theoretical literature predicts that geographic concentration encourages vertical disintegration of firms. Nevertheless, empirical evidence of this prediction is limited, especially in developing countries. Using data on manufacturing firms from China, this paper documents a positive correlation between geographic concentration and vertical disintegration. Additionally, this paper uses the instrumental variable approach to address the issue of endogeneity and finds that geographic concentration has a positive causal effect on vertical disintegration.     

产业集聚程度与城市化水平相关性的实证分析--以1988～2003年的广东省为例

不论是产业集聚还是城市化问题,目前已经有很多研究成果和结论,但是对于二者相关关系的实证研究尚少.本文采用地理集中指数来衡量产业的集聚程度,并以广东省的城市化数据为例,对两者建立回归模型,发现二者存在正的相关关系,由此得出,由产业集聚带动的人口、资本、技术的区域集中,是我国当前城市化过程中应遵循的一个规律.     

Market structure and competitive conditions in the Arab GCC banking system

This paper investigates the market structure of Arab GCC banking industry during the years of 1993–2002 using the most frequently applied measures of concentration k-bank concentration ratio (CRk) and Herfindahl–Hirschman Index (HHI) and evaluates the monopoly power of banks over the ten years period using the ‘H-statistic’ by Panzar and Rosse. The results show that Kuwait, Saudi Arabia and UAE have moderately concentrated markets and are moving to less concentrated positions. The measures of concentration also show that Qatar, Bahrain and Oman are highly concentrated markets. The Panzar–Rosse H-statistics suggest that banks in Kuwait, Saudi Arabia and the UAE operate under perfect competition; banks in Bahrain and Qatar operate under conditions of monopolistic competition; and we are unable to reject monopolistic competition for the banking market in Oman.     

Coping with sales call anxiety: The role of sale perseverance and task concentration strategies

The authors study how salespeople cope with social anxiety during customer contacts and find that two tactics, sale perseverance and task concentration, ultimately reduce dysfunctional protective actions. Both coping tactics, however, are differentially moderated by strength of felt physiological sensations and strength of negative expectations and thoughts. Salespeople experiencing anxiety cognitions should distract themselves by concentrating on their task to free up their thinking in relation to the task at hand. Engaging in behaviors to modify the situation by persevering on the sale, on the other hand, occupies action space and should be the coping strategy of choice for those salespeople confronting physiological sensations in relation to felt anxiety. Hypotheses are tested on a sample of 171 salespersons.

Managerial ownership,board monitoring and firm performance in a family‐concentrated corporate environment

Using data from Hong Kong, a market that has family‐concentrated ownership structure, we examine the relation between managerial ownership, the board of directors and firm performance. We first conduct analysis on the managerial ownership and firm performance to derive the turning points where either ‘convergence of interest’ or ‘entrenchment’ effect of managerial ownership is dominant. Based on these estimated turning points, we find that at low and high level of ownership, effective board mitigates the entrenchment effect associated with managerial ownership; at medium level of ownership, board effectiveness is less demanded. These findings suggest that managerial ownership and board monitoring are substitutes in mitigating the agency problem between managers and shareholders. We also find that effective board curbs the excessive compensation by entrenched managers to themselves at low level of managerial ownership.     

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.
