大多數關於企業併購的研究焦點著重於財務考量、人力資源管理或併購案之操作及流程管理，而本論文嘗試以整合性的方式，討論併購案之所有重要面向，包括許多被忽略的主題，例如：企業變革和重整、商業策略、工業關係、無形資產鑑價等。 / Most researches on mergers and acquisitions (M&A) focus on financial matters, human resource management, or the operation and process management of the deal. This thesis tries to bring together all the essential elements of each domain, including subjects that are often overlooked or treated superficially by others, under an integrated aspect. Factors including corporate change and reorganizing, business strategy, industrial relations, assumptions-driven planning, entrepreneurship, post-merger integration, business alliances, deal structuring and strategies, financial modeling and simulation, and valuing intangible assets such as intellectual properties are integrated into a feasible model from the perspective of due diligence. Practical examples and contemporary business cases and figures in the Western world are used for analyzing how mergers and acquisitions can be successful with win-win solutions through due diligence. Five real cases excerpted from three Taiwan high tech companies are examined in their M&A activities and are discussed as a series of interdependent movements in which each activity actually occurs. Suggestions and implementation are then proposed. While intended for reference of companies in pursuit of mergers and acquisitions, this thesis also aims to have broader application for market appeal in both executive development and training programs. For those who are hoping to become or who are actively pursuing careers as financial analysts, chief financial officers, corporate treasurers, operating managers, investment bankers, business brokers, portfolio mangers, investors, as well as corporate development and strategic planning managers, this thesis and referred literatures can work as handy and useful references. Bank loaners, venture capitalists, business appraisers, actuaries, government regulators and policy makers, and entrepreneurs will also be the beneficiaries of the study.
