abstract: 现今的理论研究及实践表明，供应链上各个企业进行协调运作的基础是节点企业间有效信息进行高效传递。但供应链上下游企业在合作过程中通常存在信息不完全对称现象、牛鞭效应等问题，供应链中信息传递的实时性及真实性受到较大影响，这也是导致供应链管理整体效率不高的原因之一。因此，供应链伙伴间信息共享问题已是国内外学者普遍关注的焦点。本文旨在针对目前我国家居供应链企业间信息沟通不畅、信息共享不充分的问题及其理论研究的不足，来开展针对影响家居供应链企业间信息共享因素的实证研究。本文基于家居供应链这一特殊的行业供应链，建立基于家居供应链企业间信息共享关键影响因素理论模型，通过实证方法来寻找影响供应链企业间信息共享的关键因素及其具体影响程度。 在已有文献的基础上，本文提出信任、共同愿景、信息技术能力、渠道权力结构与信息共享间影响关系的概念模型，并对长三角及珠三角地区家居供应链经销商企业进行问卷调查研究。最后在回收的 164 份有效问卷基础上通过数据分析来验证假设。研究结果显示：(1)不论是家居工厂与经销商间还是家居卖场与经销商间，信任对共享信息的内容和质量都有显著正向影响。(2)家居工厂与经销商间的共同愿景对彼此间信息共享内容有显著正向影响作用，但对信息共享质量作用不明显。而家居卖场与经销商间的共同愿景对信息共享的内容和质量都有正向影响作用。(3)经销商的信息技术能力对双方间信息共享的内容和质量都有显著影响，同时，还能促进家居工厂与经销商之间的信任，间接影响双方的信息共享程度。(4) 家居卖场与经销商间的渠道权力对双方间的信任程度有显著影响，而对双方间的信息共享没有直接影响。 本研究主要研究贡献在于：发现影响家居供应链信息共享的关键因素，弥补了现有文献对中国供应链企业信息共享影响因素研究的不足，特别聚焦于家居供应链；从供应链上下游整体角度出发，探讨了中国情境下信任、共同愿景、信息技术能力和渠道权力结构与信息共享之间的作用机理。 / Dissertation/Thesis / Doctoral Dissertation Business Administration 2019

Abstract 1: In this paper, we investigate the effects of internal corporate governance on the length it takes to remove a CEO after the initial sign of poor firm performance. We find that firms that have a better quality of internal corporate governance are quicker to remove poor-performing CEOs. This result persists after controlling for other factors that might influence the CEO removal decision. Abstract 2: Employing a sample of voluntary CEO turnovers selected from S&P 500 firms over the period 2004-2009, I investigate the impact prior firm performance on a CEO’s potential of being hired on an equivalent job in a similar company. I find that the better the performance of the previous firm, the quicker is CEO being hired. In other words, the better the previous firm performance, the better is the CEO’s potential to a land a similar job faster. The result prevails even in the presence of control variables, such as the CEO’s education, tenure, age and gender. The better performers in previous firms also seem to yield greater improvement in performance of their new employers.

E-commerce is today a very attractive market with growth prospects and opportunities for new companies to establish themselves and start operations. Since the establishment of Internet and the evolution of how Internet is used today, there has been an increasing possibility for consumer’s to buy products online. The more expanding E-commerce business today makes companies and entrepenuers eager to establish markets online. There is though a opportunity with the expanding of E-commerce today and that is for companies to investigate how consumer’s values the risks of shopping online. This opportunity is something that companies should take in care before starting an E-commerce market. This study aims to identify consumers' perceived risk in purchasing decisions in relation to E-commerce. The study is intended to give a broader perspective to be helpful for companies who are in business with e-commerce or supposed to conduct and begin sales activities through Ecommerce. This will be achieved by showing which factors consumers find to be most affecting to their uncertainty and risk when buying online. The survey methodology used in this study was a quantitative method where we deduced hypotheses to ensure on previous research and theories that the results of our investigation was consistent with what we concuded in our study. To come up with the answers we received, we used questionnaires in which respondents were asked to answer on a seven-point scale how they felt the risk of shopping online today. The results of this study shows us that consumer’s perceived risk will grow if the purchase is of an high engagement product, we can also conclude that there will be a decline in perceived risk if the websites have good design, user friendly navigation, clear information about consumer’s warranty and right of return.
