仕欽科技企業資訊系統安全研究報告 / Abstract Information System Security of Everskill Technology Co., Ltd. for OEM Electronics Industry by Cathy Chan OEM Electronics industry has been the foundation of Taiwan’s economy for the past few decades, and has made major contribution to foreign reserves for the country. However, entering into this millennium, with the rising of the BRIC countries (Brazil, Russia, India and China), Taiwan’s OEM electronics industry is gradually losing competitive advantages. Nowadays, to improve competitiveness is the most critical issue in the industry. According to MIC of III , the integration of information technology in OEM electronics industry is a major index of Taiwan’s competitiveness. The higher the information system is integrated, the more the system should be secured. Otherwise, in case of any abusage, the damage can sometimes beyond our imagination. The collapse of Barings Bank is a best lesson for all of us to learn. Therefore, we should put equal emphasis on information system security as well as information system integration. The scope of this paper is to analyze the information system security of Everskill Technology, an OEM electronics company, to find out the weakness of the existing IT framework, and better improvement for future information system security in the company and OEM electronics industry. This paper will thoroughly examine the existing structure of the information system of Everskill Technology, e.g. how the structure is built? Why it is built this way? How is the information system secured? What are the factors that affect information system security? How to modify the factors? The paper will also highlight some incidents, pin point the weakness of the system, and also provide suggestions for future improvements. My conclusion is that the successful implementation of information system security to an organization is not just about how advanced the products/technology are, or how complete the procedures/checklists are, the people(agents) in the organization also play an very important role. As a professional manager of the organization, I believe we should always be aware of the relations among products/technology, procedures/checklists and the people (agents). Only through perfect balance among the three factors, we can successfully implement and secure information system of the organization. Ultimately, this paper can provide an agenda for any other OEM electronics company who wishes to improve her information system security and hopefully can be a stimulation of improvement for the industry.

本文主要探討影響券商分析師所發布的研究報告目標價預測誤差的因素，以及了解券商目標價預測誤差是否會在不同的情況下有所不同，如券商國籍、分析產業。本文研究期間為2008年至2014年，目標價預測總共有效樣本有39,585筆，資料來源為CMoney，其中外資券商發布百分比共有30.16%，本土券商發布百分比有69.84%。電子業占總樣本百分比有63.21%，非電子業占總樣本百分比有36.79%。從分析師發布研究報告的趨勢來看，分析師把較多的資源以及心力在台灣電子業，因此本文亦想了解台灣分析師對於電子業的目標價預測能力使否顯著優於非電子業。此外，1998年全球大型投資銀行及專業券商因台股成交量日益龐大，大舉進入台灣市場，而外資券商所發布的研究報告，主要提供給三大法人，其買賣動向往往是市場中的焦點，因此外資券商目標價預測是否有比本土券商來的高，也是一門有趣的課題值得我們在本文探討。 本文利用Bonini et al.(2010)方法並加以修正，重新定義目標價預測誤差，差別在於本文所探討的目標價預測誤差為根據分析師所發布目標價，在一定的投資期間內與真實股價最接近的時點的誤差程度。最後從實證結果發現以下幾點結論：(一) 目標價的時效性在超過發布三個月後逐漸消失；(二) 電子業的目標價預測誤差大於非電子業；(三) 外資券商分析師目標價預測誤差大於本土券商；(四) 外資持股比重越高，會使目標價預測誤差縮小；(五) 動能表現會影響到分析師的目標價之判斷，且二者呈反向關係。
