本文根據2001年至2007年的普查資料，採用三階段資料包絡分析法，針對台灣47家國際觀光旅館進行效率評估。DEA評估結果顯示，國際觀光旅館各項效率值皆存在顯著差異，且在產出不變下，平均可以減少48.89%的投入使用量，而無效率主要來自不適當的生產規模，多數國際觀光旅館規模無效率原因為產能未充分發揮；SFA迴歸評估結果顯示，業務集中度及旅客類型集中度愈高、市場集中度愈低、加入國際連鎖集團、於國內增設分館、位於風景區、旅館客房數愈少、其他費用比率愈高及無SARS事件影響，皆對管理效率有正向影響；2002年至2003年國際觀光旅館純技術效率呈現顯著負成長，2003年至2004年純技術效率則呈現顯著正成長。 關鍵詞：效率、三階段資料包絡分析法、隨機邊界分析法

稅捐分處是最接近民眾之第一線機關，直接影響民眾對稅捐機關之觀感，其亦為最小的單位，卻肩負稅收稽徵、防止逃漏、為民服務等業務，故衡量分處的稽徵績效刻不容緩。本研究以臺北市稅捐稽徵處所屬13個分處為研究對象，並以員額、稽徵成本與設備數量等作為投入項、以各稅實徵淨額、違章裁罰金額、欠稅清理金額與人民申請案件數作為產出項，運用三階段資料包絡分析法進行衡量，評估臺北市稅捐稽徵處所屬各分處之技術效率，探討外生因素對產出差額的影響，並與原稽徵績效考核成績進行比較。實證結果顯示，在排除外生因素之影響後，整體效率值是較前提升的，而造成無效率的原因，部分可歸責於資源的浪費、部分可歸咎於未達最適規模；外生變數對大部分的產出差額具顯著影響，轄區內營業家數愈多，稅收金額較高；位於臺北市南區，稅課收入亦較多；前年平均國民生產毛額對大部分技術效率有負向影響；實務面之稽徵績效考核因考慮面向較廣、涉及過多非相關考評項目而淡化了各分處稽徵效率，為使對分處考核制度更為嚴謹，建議使用一套客觀的效率準則來衡量稽徵效率並加以評估，較能反映分處實際之稽徵績效。

在運動產業逐漸興起的現代，如何評比球隊或運動員的表現好壞，似乎成了現在新興的熱門話題。經濟學上用來評估一家廠商的生產績效優劣，常用的是生產效率分析，生產活動偏離生產邊界的程度代表不效率高低。而球隊比賽的過程就像廠商生產的過程，運用各種投入得到產出。在籃球比賽中，比賽的投入可為球隊的各種技術統計，例如：投籃命中率、抄截、火鍋…等等，產出則是比賽的得分數。因此，在本篇文章中，我們利用經濟學中的生產效率分析來分析球隊的表現優劣，即評估各球隊發揮其潛能的程度。 評估生產效率的模型有很多，由於比賽的性質，有時候統計誤差、運氣也佔了很重要的部份，所以在選擇模型時，選的是隨機邊界效率分析模型（Stochastic Frontier Approach, SFA），除了利用隨機邊界分析模型分析球隊的生產效率，也利用預估的效率值來預測比賽結果排名，並與一般常用來預測結果的模型PROBIT MODEL做比較。我們利用大陸男子甲A籃球聯賽2003-2004和2004-2005賽季作為實證樣本，發現隨機邊界分析模型不只可以用來評估效率，在預測比賽結果排名上，隨機邊界分析模型預測能力則與PROBIT MODEL沒有顯著統計性的差異。 關鍵字：生產效率、隨機邊界分析法、運動產業 / Today, sports industry is getting popular, and how to evaluate the performance of sports teams or players seems also to be a newly hot interesting topic. In economics, production efficiency is often applied to evaluate a firm’s production performance. The inefficiency of a production activity is measured as its deviation from the production frontier. The process of a sport game is similar to a firm’s production process, which transforming various inputs into output(s). For basketball games, inputs can be the various technical statistics, such as field goal rate, steals, blacks, assistant attack, etc. Output(s) can be the scores of the teams got. Therefore, in this paper we use the production efficiency to gauge the performance of sports teams. There are many models measuring production efficiency. In this paper we choose the Stochastic Frontier Approach (SFA) to evaluate the sport team’s efficiency on account of the white noises which exist in the sport game obviously. We also use estimated efficiency scores to predict the outcome ranking of teams, and compare it to that of the PROBIT MODEL which is usually used to predict the outcome of a game. The sample we used are the results of the CBA men’s regular season and playoff season, and we found that the SFA is not only to evaluate efficiency but also can predict the outcome of competition, and its prediction ability is not significantly statistically different to that of PROBIT MODEL. Keywords: Production Efficiency, Stochastic Frontier Approach, Sports Industry

本文採用一階段隨機邊界分析法（Battese and Coelli, 1995）衡量2004 年第一季至2008 年第三季台灣上市櫃證券商的技術效率，並將Orea（2002）提出的產出導向一般化Malmquist生產力指數改寫成投入導向模式，用來分析台灣上市櫃證券商的生產力變動情形。實證結果顯示，小型券商之經營效率平均而言比大型券商之經營效率高，而大部分的證券商都呈現規模報酬遞增的技術狀態，可見台灣上市櫃證券商整體而言規模不夠大，必須設法再擴大至適當的規模方可發揮規模經濟效果。另外，較多的股本雖然理論上具備較強的競爭優勢，但可能沒有適當的決策支持，造成資源浪費反而降低經營效率；股價指數愈高，在相同的投入之下有較多的產出表現且較有能力調整規模至規模報酬較佳的狀況，因而提高經營效率。 / This paper adopts one-stage stochastic frontier analysis (Battese and Coelli, 1995) to measure technical efficiency of listed securities firms in Taiwan from the first quarter of 2004 to the third quarter of 2008. In addition, inspired by the Orea (2002) output orientated productivity model, this paper derives an input orientated generalized Malmquist productivity index to analyze the productivity change of the firms. The empirical results reveal that smaller securities firms are more efficient than larger securities firms in average. The majority of securities firms are operating with increasing returns to scale, indicating that the scale of listed securities firms in Taiwan are generally not large enough, so firms need to enlarge their scale in order to get the effect of economies of scale. Although more capital stocks possess stronger competitive advantage theoretically, without proper strategy to support the firms may waste resources and result in operational inefficiency. Operational efficiency is positively correlated with stock index.

現今世界趨勢已朝向全球整合的方向邁進，隨著科技日新，世界各國跨越地域隔閡，不論是在政治、經濟、科技、文化等各方面往來接觸愈來愈頻繁，中國大陸近年來與世界經貿關係連結更為緊密，同時亦對外開放直接投資，使跨國企業逐漸擴大進軍中國大陸之版圖，享受中國大陸豐沛之廉價勞動力。 然而，開放外人直接投資(Foreign Direct Investment, FDI)勢必為中國大陸相關之產業或總體經濟帶來某種程度之影響，儘管外人直接投資可帶來充沛之資本及先進之技術，但亦有可能加劇國內市場競爭，不利於本土廠商。 本文運用1998-2006 年「中國工業企業統計數據庫」中之電子業廠商，建構追蹤資料模型(Panel Data)，並運用隨機邊界法（stochastic frontier approach）估計中國大陸本資、台港澳資及外資企業生產效率，藉以衡量FDI之外溢效果。根據實證結果我們發現：中國大陸電子業之外人直接投資存在正向外溢效果及正向之技術移轉，顯示FDI之進入將有助於提升中國大陸電子業本土廠商之生產力。此外，我們同時發現FDI集中投資的結果將可能造成外溢效果的減低，除此之外，經濟區位亦是影響外人直接投資所帶來之外溢效果及技術移轉效果之重要因子之一。 / Global integration is the world trend nowadays. With the breakthrough of technology, the geographical barriers no longer exist. It would be much closer with other countries in many fields, such as politics, economics, technology and culture. In recent years, China has a closer economics and trades linkage with the world. As the results of openness to foreign direct investments, more and more multinational enterprises enter to China, expanding their scale and being benefited from the low-cost labor of China. China is benefited from the plentiful capital and advanced technologies of foreign direct investments; however, the openness to FDI might cause the competition which can aggravate in domestic market and hurt the domestic firms. The research uses the data of electronic firms from Chinese Industrial Enterprises Database. We apply panel data model and stochastic frontier approach to estimate the production efficiency of Chinese, Taiwanese, Hong Kong, Macanese and Other foreign enterprises. According to the empirical results, we discover that there are positive spill-over effects and technology transformation from foreign direct investments in Chinese electronic industry. These results indicate the entry of FDI will promote the productivity of Chinese electronic firms. Beside the positive results, we also discover the negative deduction stem in concentrated investments; furthermore, the spill-over effects and the technology transformation effects are affected by the economic location.

署立醫院為全國分佈最廣，且數量最多之公立醫院體系，負有貫徹國家公共衛生政策之責任，故其經營績效之良瓠影響各地區民眾健康照護水準甚鉅。惟署立醫院目前之經營仍仰賴國庫補助，在國庫補助逐年縮減的情形下，署立醫院惟有提升經營績效，才能維持醫療照護品質。 本研究運用三階段DEA分析法，評估步驟第一階段運用一般DEA分析法，以原始投入及產出項衡量各DMU的相對效率值，求得總差額值；第二階段運用SFA將差額分解，探討環境變數對於各DMU的影響程度，並利用SFA的結果調整產出項，將處於不同外在環境或是不同運氣之DMU，調整為相同之情況；第三階段則利用第二階段調整後的產出項，再次以DEA分析法評估調整後的效率值。 由研究結果可知，各署立醫院之無效率主要來自於非處於最適經營規模所造成之無效率，整體而言，大部分署立醫院之產能實際上係存在擁擠現象，而產生規模不經濟，故建議主管機關應嘗試調整部分署立醫院之經營規模，考慮醫療的投入與產出的效率性，以符合經濟規模的要求，應可有效提升管理效率。 另部分署立醫院在各方面之管理效率均較呈現相對較佳之結果，因此，建議由主管機關主導，加強各署立醫院醫療資源之整合及技術交流，透過相互觀摩學習，以同時提升整體署立醫院之經營管理效率。至有關目前區域聯盟之整合作業，建議「北區區域聯盟」應加強注意手術業務部分之資源整合，而「中南區區域聯盟」應加強注意門診病患業務部分之資源整合。

To date there is little evidence on the effect of property-liability (P-L) insurer's business strategy and organizational structure change on their frontier efficiency performance and productivity change. This issue is important since traditional theory assumes firms that minimizes cost and maximizes profit with more efficient strategy will survive in the long run. The main goal of this dissertation is to examine the efficiency performance in the U.S. P-L insurance industry using frontier efficiency and productivity methods. This dissertation consists of three essays on the efficiency studies. The first essay uses the data envelopment analysis to examine the efficiency performance and economies of scope for nonspecialists and specialists in the U.S. P-L insurance industry. The empirical evidence suggests that nonspecialists (specialists) dominate specialists (nonspecialists) in producing nonspecialists (specialists) input–output vectors and provide evidence for the coexistence of economies of scope and diseconomies of scope in the U.S. P-L insurance industry. Our second essay uses the stochastic frontier analysis to examine whether nonspecialized strategy dominates specialized strategy in the U.S. P-L insurance industry. The empirical evidence supports that both the nonspecialized hypothesis and the specialized hypothesis hold for different types of P-L insurers. Our third essay investigates whether the conversion of U.S. P-L insurers improves their efficiency performance before and after conversion. The empirical evidences of the value-added approach and the financial intermediary approach indicate that converting insurers experience improvement in their efficiency relative to mutual counter samples after the conversion, supporting the efficiency hypothesis proposed by Mayers and Smith (1986). Overall, the evidence of this dissertation shows that P-L insurer's diversification strategy and organizational structure change has significant impact on their frontier efficiency performance and productivity change.

地方稅捐稽徵機關績效之良窳攸關地方政府庫收，更直接影響地方經濟成長、資源配置效率與所得分配之公平；本文試圖採用能排除外在因素與隨機干擾之三階段產出導向資料包絡分析法（以下簡稱DEA），針對23個地方稅捐稽徵機關2004年迄2008年資料進行管理效率評估，再以隨機邊界分析法（以下簡稱SFA）分離外生因素及隨機干擾以調整各機關產出至相同基準後，再評估排除外在與隨機干擾因素的管理效率。 未考慮外生因素與隨機干擾的DEA效率評估結果顯示，有高達88.7%及82.6%的地方稅捐稽徵機關分別於技術效率及純技術效率上尚有改善空間。第二階段SFA估計結果顯示，土地移轉現值、機關內大專畢業以上員額之比例及員額平均年齡對管理效率皆有正向影響；而總統大選期間及有高鐵停靠站之縣市除對部分產出無顯著影響外，對管理效率之提升亦具優勢；然而，服務轄區土地面積與實徵淨額之效率呈負相關，卻與違章漏稅裁罰效率呈正相關；地方首長選舉期間除為避免清理欠稅招致民怨而降低技術效率外，對其他管理效率則皆呈正相關；又都市計畫面積占稽徵區域比例與地方稅實徵淨額之管理效率呈正相關，卻與欠稅清理效率呈負相關。調整後之DEA結果顯示各項效率值與調整前比較皆存在顯著差異，顯示排除外生因素與隨機干擾影響以避免效率值被錯估確有其必要性；但仍有高達93.05%及68.7%之地方稅捐稽徵機關分別於技術效率及純技術效率上存有改善空間；又多數稽徵機關處於規模報酬遞增階段，即產能過剩而造成資源浪費。另與財政部稽徵業務考核成績比較分析，在規模效率平均值排名方面，除臺南市外，甲組機關排名普遍優於乙組機關；但純技術平均效率值之排名卻有一半以上之甲組機關表現反而不如部分乙組受評單位；顯示甲、乙組之分類歷經多年仍沿襲舊有分組將使各機關未能於適合之群組中受考而錯估其績效。 基於上述實證研究結果，本文提出下列政策性建議： 一、建議逐期分階段調整人力及預算至最適規模，以善加運用資源降低產能過剩情形。 二、建議各機關應引用環保之共乘概念，加強政府機關間橫向溝通、聯繫與合作。 三、若情況允許，建議可不區分甲乙組針對全體地方稅捐稽徵機關進行考核。若人力、時間或其他情況不允許，建議研擬具體方案隨各機關規模改變而有重新分級之機制。 四、建議甲組機關亦可選擇純技術效率較佳之乙組機關作為觀摩學習之對象。 五、建議財政當局可考慮將外在因素之影響納入評核，以提升考核之信度與效度。 最後，臺灣自2010年底起將有部分縣市改制為直轄市，考核編組方式勢將有所變革，有待後續研究者追蹤探討；而改制後所引起之資源重分配亦可作為未來之研究議題。 / The Performance of Local Tax Bureaus is relevant to the revenue of Public Treasury, and even has direct impacts on local economic growth, efficiency of resource allocation and equity of income distribution. This paper attempts to use three-stage out-oriented DEA which can rule out the external factors and the statistical noises to evaluate the efficiency of 23 Local Tax Bureaus in Taiwan during the period of 2004 to 2008. After measuring slack variables of each Bureau in the first stage, the Stochastic Frontier Analysis (SFA) model is used to separate the external factors from the statistical noises, and then adjust the output of each Bureau to the same benchmark. Finally, DEA is again used to evaluate the efficiency of 23 Local Tax Bureaus. The DEA efficiency evaluation results in the first stage show that up to 88.7% and 82.6% of the Local Tax Bureaus still have an ample room to improve their technical and pure technical efficiency. In the second stage, the SFA model estimates show that “the present value of land transfer”, “the proportion of post-graduates in the Bureaus” and “the average age of the staff” have positive effects on the efficiency. “The period of Presidential Election” and “the cities or counties that Taiwan High Speed Rail have set station up” have insignificant impact on part of the outputs, but still have the advantages to enhance the efficiency. However, “the expanse of land in service area” has a negative correlation with the efficiency of net taxation, but is positively related to the efficiency with the fine of illegal tax evasion. “The election period of Local County Executive” has a positive correlation with the efficiency except that tax arrears liquidation might reduce technical efficiency. “The ratio of urban-planed area to the tax levy regional” and the efficiency of net taxation are positively correlated, but negatively related to the efficiency of tax arrears liquidation. After excluding external factors and the statistical noises, the third-stage DEA evaluation results are significantly different from those in the first stage, indicating that it is necessary to exclude impacts of external factors and statistical noises in order to avoid the misjudged value of efficiency. There are still as high as 93.05 % and 68.7% of the Local Tax Bureaus have an ample space for improvement respectively on technical efficiency and pure technical efficiency. Most of the Tax Bureaus are at the increasing return of scale stage, implying that the surplus of capacity cause the waste of resources. Finally, compared with the performance evaluation held by Ministry of Finance, the empirical results in this study show that although the classification of Local Tax Bureaus has been adopt for many years, Bureaus’ performance evaluation results might be misjudged in the unsuitable group. Based on the above empirical results, this research attempts to propose the following policy suggestions: 1. It is recommended to adjust the phase of manpower and budget to the optimum scale for the best using of resources and to reduce inefficiency of excess capacity. 2. Enhancing horizontal communication among government agencies may improve the efficiency of Local Tax Bureaus. 3. If possible, it is recommended to evaluate Local Tax Bureaus without classification. If not, a mechanism of re-rating according to the scale change of Local Tax Bureaus may be needed. 4. It is proposed that Local Tax Bureaus of Group A can take lesson from those of Group B with better pure technical efficiency to learn from. 5. It is suggested that government authorities have to exclude the effect of external factors to improve the reliability and validity of performance evaluation. At the end of year 2010, several counties will be restructured in municipalities. The classification of Local Tax Bureaus for performance assessment must be changed. The reallocation of resources caused by restructuring may be used in future studies.
