台灣經濟屬於淺碟型經濟，且受限於缺乏自然資源，所以資本的形成相當的不容易。為求經濟的發展，資本的形成，尤其是固定投資的累積相當的重要。而資本形成的數種財源中，以僑外直接投資對國際收支與通貨膨脹的壓力影響較小，並能引進新生產技術及經營管理知識，從而促進產業的持續成長與企業管理現代化理想的實現。台灣之所以能成為經濟上的亞洲四小龍之一，這當中經濟成長的背後資金來源，僑外商的直接投資是不可或缺的。近年來，台灣的名目利率不斷下跌，甚至實質利率為負的情況下，投資動能卻仍顯不足。為瞭解構成廠商投資意願的決定因素，故以對投資具相當敏感度的僑外商為研究的主要對象，所以本文的主要目的即是探討僑外直接投資台灣的決定因素。 本研究使用1995年至2004年間的時間數列月資料，以普通最小平方迴歸模型，估計僑外資、僑資、外資、製造業及服務業等五種模型的直接投資決定因素。結果顯示在僑外資及外資的模型中，其顯著變數有工資、利率、世界競爭力及政黨輪替。僑資模型的顯著因素有犯罪率及政黨輪替。製造業模型的顯著變數有工資、匯率及利率。而服務業模型則有工資、利率及研究發展經費為顯著變項。另各模型時間變數方面，僑外資、外資及服務業等模型的第6年虛擬變數具顯著效果。在月虛擬變數上，投資正相關的月份僑外資為6、7月及10至12月；僑資為7、8兩月；外資於5月後各月；製造業則為3月及5月後各月；服務業則為7、11及12月。又僑資及服務業兩模型中，4月均為負相關。至於經濟成長率、每人國內生產毛額及政黨比率等不顯著變項，表示均非僑外商投資所關注的因素。 / Taiwan’s saucer-shallow economic scale and scarce natural resources make capital formation very difficult. Nevertheless, capital formation, especially accumulation of fixed investment, is essential to economic development. Among various sources of capital formation, foreign direct investment imposes least pressure on the balance of payments and inflation, introduces innovative technology and management skills, and hence contributes most significantly to sustainable industrial development and the realization of business management ideals. Taiwan ranks among the four newly-industrialized Asian tigers. Among the funding sources that have promoted Taiwan’s economic growth over the years, direct investment from overseas Chinese and foreigners plays an indispensable part. In recent years, however, even though nominal interest rates have continuously fallen, at times even to the level of negative real interest rates, investment momentum still appeared weakened. Based on this observation, this study tries to understand what drives decisions to invest in Taiwan by focusing on overseas Chinese and foreign investors who are highly investment sensitive. The main purpose of the study is to discuss the determinants of overseas Chinese and foreign direct investment in Taiwan. This study applies the Ordinary Least Square (OLS) Regression model to analyze the monthly time-series data during the period of 1995-2004. Determinants of direct investment are examined in five groups, i.e. overseas Chinese & foreign investment, overseas Chinese investment, foreign investment, the manufacturing sector, and the services sector. The result shows that wages, interest rates, world competitiveness, and the rotation of ruling parties are the most important factors for overseas Chinese & foreign investment, and foreign investment. Overseas Chinese investment is significantly affected by the crime rate and the rotation of ruling parties. For the manufacturing sector, wages, exchange rates and interest rates are important variables. Wages, interest rates and R&D spending significantly affect investment in the services sector. In terms of the time variables in each group, the sixth year dummy variable has a significant effect on overseas Chinese & foreign investment, foreign investment, and the services sector. With regard to monthly dummy variables, positively correlated to investment are June, July, and October to December for overseas Chinese & foreign investment; July and August for overseas Chinese investment; May to December for foreign investment; March, and May to December for the manufacturing sector; and July, November, and December for the services sector. In addition, April shows a negative correlation for both overseas Chinese investment and the services sector. Variables with insignificant effects, including economic growth rates, per capita GDP, and the congressional seats of political parties, are not among the concerns of overseas Chinese and foreign investors.

從2000年費率主管機關公布有線電視基本頻道收視費用之每月每戶上限為新臺幣600元，並逐年核定其價格上限。本研究透過超越對數成本函數及需求函數，探討我國有線電視2004年至2008年間經營概況，實證結果得知： 一、我國實施價格上限管制法，管制有線電視基本頻道收視費用之機制是具有效性，且費率主管機關近年來價格管制，是增加消費者剩餘方向前進。 二、在每年所核價格上限下，系統經營者平均每戶約新臺幣107元獲利空間；系統經營者對於將所節省的成本反應至收視費用上，是不積極的。 三、有線電視產業之價格需求彈性為-0.8107，顯示有線電視服務已逐漸成為國人生活上的常用品，符合目前社會經濟現象。 四、有線電視產業之家戶所得需求彈性為0.6951，顯示有線電視服務為正常財。 五、有線電視平均成本隨著訂戶數逐年增加而下降趨勢，顯示有線電視產業具有規模經濟特性，其平均成本下降原因主要來自於固定成本下降。 六、系統經營者之邊際成本隨著年度增加而趨向新臺幣300元至400元間集中或收斂。以組織結構來看，各集團5年平均邊際成本在新臺幣348元至405元間。以整體有線電視來看，5年平均值約為新臺幣367元。 七、以組織結構來看，各集團5年平均成本在新臺幣417元至470元間。以整體有線電視來看，5年平均值約為新臺幣438元。
