本研究欲探討分析師推薦對管理當局所釋出資訊量之關聯性，當分析師越強力推薦公司時，公司的管理當局將願意提供較多的資訊給分析師做為預測的依據，則分析師對公司盈餘的預測也越準確。研究結果發現給予公司較佳推薦的分析師，預測準確性確實比給予公司較差推薦的分析師高。 之後再利用台灣證券暨期貨市場發展基金會設立的資訊揭露評鑑系統，探討資訊較為透明的公司，因為管理當局自願提供較多的資訊，即便分析師強力推薦，可能也無法得到額外的資訊，所以分析師推薦的效果應比資訊揭露較不透明的受評公司差。實證結果發現資訊揭露較透明的受評公司，分析師的推薦效果確實比資訊訊揭露較不透明的受評公司差。 / This thesis examines directly whether that managers provide more (less) information to analysts with more (less) favorable stock recommendations, based on the Barron et al. model (1998). Prior study documents the relative forecast accuracy of analysts before and after a recommendation issuance under the assumption that increases (decreases) in management-provided information will increase (decrease) analysts’ relative forecast accuracy. In contrast, this paper directly measure amount of information based on Barron et al. model (1998), and examine whether amount of information varies between pre- and post- a recommendation. Contrary to our prediction, the results show no significant difference in amount of information after and before recommendation issuance. However, we do find that analysts issuing more favorable recommendations experience a greater increase in their relative forecast accuracy compared with analysts with less favorable recommendations. In addition, we also find that the association is smaller for firms with higher information transparency than those with lower information transparency. The information transparency is measure by whether firms are listed in Taiwan Securities & Futures Information Center’s Information Disclosure and Transparence Ranking System (therefore TSFIC).

本研究之目的主要在探討國民中小學校長評鑑系統的建構及有關研究。所採用的研究方法包括：文獻分析、問卷調查與訪談法。在文獻分析方面：分別就校長評鑑系統建構的基本理念、可能的探究取向與模式、英美兩國與國內國中小校長評鑑系統的發展情形、校長評鑑系統的後設評鑑標準與可能存在的問題等加以探討。在實證研究方面：以自編調查工具，對各縣市教育行政人員、國中小校長、主任、教師、家長與教育學者，就規劃實施國中小校長評鑑系統的三階段歷程要素、後設評鑑標準與可能存在的問題等，進行問卷調查與訪談。綜合本研究的結論發現：國中小校長評鑑系統的建構有其重要性，落實校長評鑑可協助校長提升辦學效能。而校長評鑑系統建構的理論與實務已日趨完善，在規劃過程中可參考不同的探究取向與英美兩國的實務經驗，讓校長評鑑系統的規劃能更為完備。此外，「教育評鑑標準聯合委員會」所發展的「教育人員評鑑標準」，不僅可用來協助規劃設計國中小校長評鑑系統，亦可以之進行現有校長評鑑系統的後設評鑑，妥當的應用可確保校長評鑑系統符合正當性（prophey）、效益性（utility）、可行性 （feasibility）與正確性（accuracy）標準。完整的國中小校長評鑑系統可分成三個階段，各階段均有應遵循的原則。做好規劃設計階段的工作是成功的第一步；資料蒐集階段應能正確而完整的蒐集資訊並遵循評鑑倫理；評鑑結果與處理階段，亦應配合評鑑目的，務實的做好各項後續工作，並作必要的決定。而評鑑歷程中務必遵守正當程序與保密原則，妥善保管資料並規範查閱程序，以保障受評校長的權益。最後本研究依上述研究結論，分別針對教育行政機關、國中小校長及其他利害關係人，綜合提出規劃實施國中小校長評鑑系統的建議。 關鍵字：校長評鑑、評鑑系統、評鑑模式、後設評鑑、評鑑標準 / The aim of this study is mainly to investigate the construction of the principal evaluation system of elementary and junior high schools and its related issues. The research methods included document analysis, questionnaires and interviews. The analysis of documents covered the basic concepts of the construction of principal evaluation systems, possible research approaches and models, the development of school principal evaluation in Taiwan as well as in the United States and Britain, meta-evaluation standards, and potential problems. A field study was conducted to explore the factors of the three phases of the design and implementation of a principal evaluation system, the meta-evaluation standards, and potential problems. It has employed questionnaire surveys and interviews to gather information from local government education administrators, school principals, deans, teachers, parents, and education academics. It has been found that the construction of school principal evaluation systems is more important than ever, and it could help raising school effectiveness. The construction of principal evaluation systems has been maturing in both theory and practice. Consulting different theoretical approaches and the practice of the United States and Britain makes the planning of principal evaluation systems comprehensive. Furthermore, the Personnel Evaluation Standards, developed by the Joint Committee on Standards for Education Evaluation in the United States, not only can serve as criteria for designing systems for school principal evaluation, they can be used to meta-evaluate ongoing principal evaluation systems as well. Applied appropriately, they should ensure that the standards of propriety, utility, feasibility, and accuracy are maintained in the principal evaluation system. A comprehensive system for school principal evaluation consists of three phases and each has its own rules to follow. The first phase is to plan and design it deliberately. Information should be gathered accurately and completely in the phase while the evaluation ethics is abided by. The consequent works should be taken care of in line with the purpose of the evaluation in the third phase of the processing of evaluation results. Necessary decisions should be made accordingly. Due process and confidentiality should be observed when implementing the evaluation. There should be an appropriate set of rules governing procedures of access to evaluation reports and data to protect the rights of the principals evaluated. According to the conclusions above, this research has offered some propositions regarding the planning and implementation of school principal evaluation systems. These propositions are aimed at education administrations, school principals, and other stakeholders.
