A股与H股市场的差异与互动

本文选择了28家既在香港发行H股,又在内地发行A股的上市公司作为样本,研究分割市场之间的差异性和互动关系.通过对比相同上市公司在两个市场上的收益性和波动性差异,本文发现:两个市场在年报公告、中报公告、季报公告以及预告事件下获得的超额收益具有显著差异,而在分红通过公告事件下未产生显著差异;同时,除了分红通过公告(旧信息)事件未引起市场产生明显的波动以外,其余事件都对两个市场产生了显著的波动性影响.另外,我们也发现"H股引起A股变化"的可能性要大于"A股引起H股变化"的可能性.     

评价中国制造业国际竞争力的实证方法研究--兼与波特指标及产业分类法比较

本文应用内容分析法,对近年来发表在国内权威和核心期刊上有关中国制造业国际竞争力评价的重要实证文献进行了回顾与综述,分析了这些实证研究中存在的问题和可取之处,并就两个关键点进行了探讨一是在进行产业国际竞争力的评价时,应该如何选取方法和指标;二是在对中国制造业的国际竞争力进行实证研究时,应当采用何种产业分类法。经过对产业竞争力四个层次的划分及与波特方法的比较,得出对中国制造业的国际竞争力进行评价的方法结论以产业利润率、全球市场份额和劳动生产率/平均工资率三者为评价指标;用相当于ISIC二分位的国内28个制造业部门进行产业分类。     

中国地区中小企业竞争力评价--对2003年规模以上工业中小企业的实证研究

随着中小企业在地区经济结构中发挥的作用日益增大,如何正确评价不同地区中小企业的竞争力状况显得尤为重要。本文认为,地区中小企业的竞争力可以通过区域影响力、经营运作力和成长发展力三方面显性指标来评价。通过构建的竞争力评价模型和相应的计量方法,我们检验得出了2003年度中国大陆30个省市自治区(西藏除外)竞争力指数及排名,并据此将各地区分为中小企业竞争力很强、较强、一般和较弱的地区。发现:各地区中小企业的竞争力与其所在地区的经济发展水平基本一致,呈现东高、中中、西低的格局。

Sharing my way to success: A case study on developing entrepreneurial ventures using social capital in an OSS community

While Open Source Software (OSS) communities provide opportunities for knowledge creation, we have a limited understanding of how entrepreneurs leverage OSS communities for their entrepreneurial ventures. Using social capital theory in a mixed methods case study, we compare entrepreneur and non-entrepreneur behaviors to investigate how entrepreneurs build social capital within an OSS community. This study shows that entrepreneurs differentiate themselves from non-entrepreneurs by focusing on cognitive and relational capital building activities, which in return makes it possible for them to leverage their social capital to influence and shape the environment in which they are operating. Our findings suggest that entrepreneurs strategically select which activities within the community to expend their limited resources on (e.g., developing code over participating in email conversations) and build their social capital more through their actions than through their words (e.g., showing their commitment to the community through code commits, bug fixes, and documentation). Given the liabilities of newness and smallness as well as other challenges faced by entrepreneurs, applying an open innovation strategy in OSS communities could be one approach where entrepreneurs, by developing and freely revealing their intellectual property to the community, share their way to success via OSS-infused entrepreneurial business ventures.

The negative spillover effect of food crises on restaurant firms: Did Jack in the Box really recover from an E. coli scare?

Despite the enormous impact of food crises on restaurants, limited understanding of their long-term impacts and associated factors has undermined crisis managers’ ability to handle crisis situations effectively. This article investigated the long-term impact of food crises on the financial performance of restaurant firms and identified the factors that influenced this impact. This explanatory study examined the case of Jack in the Box, whose 1993 Escherichia coli scare was the first and largest restaurant-associated food crisis in modern times. An event study method was used to uncover stock price movements of Jack in the Box, in conjunction with 73 unrelated food crises that occurred from 1994 to 2010. Stock prices of Jack in the Box exhibited significantly negative responses to other firms’ food crises, moreover, the negative spillover effect was stronger if the crisis occurred closer in time, was similar in nature, and was accompanied with no recall execution. These findings shed light on the long-term financial impact of food crises and offer insights for crisis managers to develop more effective crisis management strategies.
