經濟學上有所謂先進者優勢 (First-mover Advantage) 的這個概念，認為一個產業的先驅公司，相較於後進的競爭對手，應該存在著許多優勢，例如: 可在對手未出現前先搶下大塊地盤，對市場定價的擁有主動權，以及在產業標準制定過程上的影響力及品牌知名度等等。 但是當先進者能處於原有市場之市場榮耀之際，很可能因為沉溺於舊有的成功，而對產業的新技術視而不見，或是低估新產業的崛起速度導致喪失先進者先機而兵敗如山倒。 處於典範轉移時代，產業的變遷速度已非舊有經驗可以預測，以往企業營收創新高都是大肆慶祝，但最近看市場領先者，如國內的宏碁電腦或是國外的諾基亞，均是在營收創新高時被調降企業評等，發出警訊。如近期宏碁電腦在PC市場已邁向全球第一名挑戰惠普HP之際，卻發生毛利下降，並警覺在智慧型手機市場已落後宏達電一大截，且現有產品線也難有競爭優勢而陣前換將。再看諾基亞，2007年營收或穫利都創新高，但到2011年市值僅Apple的7%，連續十四年的手機市佔率第一名也被三星超前;由於大部份都是低階手機，手機獲利狀況也僅Apple的三分之一。反之，後進廠商由於尚未形成經濟規模或商業模式，透過模仿式創新或破壞式創新，反而更容易動態調整策略去因應變動的環境或發現尚未被滿足的市場。在典範轉移時代，成功不是沿用舊有成功方式，而是需要想像力來找到創新的機會。而一個新進的軟體廠商，該掌握哪些競爭優勢，才能迅速搶佔市佔率? 本研究以導航產業為例，來看導航應用軟體的發展趨勢並比較先後進者優劣勢。導航產業由2003年神達電腦推出第一台結合GPS導航晶片的PDA Mio 168以來，迅速在市場上熱銷，並帶來台灣市場導航產業的一片榮景。但由於市場飽和，及受到車機與智慧型手機的雙面夾擊，使得原本的明星產業迅速在市場萎縮，2010整體台灣市場的數量一年已不到20萬台，較之2005年已萎縮了四分之一，且平均售價下降至USD 100，毛利率從40% 掉到8%。為了突破便攜式導航機PND(Portable Navigation Device)市場衰退的重圍，研勤科技在2008年創新推出第一套在iPhone上導航的導航軟體，後進者勤崴國際科技的「導航王」手導航軟體緊接著在2009年推出，在短短一年間，賣出一百萬套軟體，此數量是傳統導航機硬體三年的市場總和，軟體銷售量為先進者研勤科技的兩倍。在推出落後於現有廠商之下，後進者是透過哪些策略取得70%導航軟體市佔率? 本研究研究問題如下: 1. 後進者的軟體廠商其策略及競爭優勢為何? 2. 配合進入時機，後進者軟體廠商該採何種競爭策略? 3. 市場變動快速時，是否後進者更有優勢? 4. 本個案研究的策略優勢，是否可提供給硬體廠商參考，增加產品區隔性? 本研究將以導航產業為例，透過幾家導航產業公司領導者訪談及次級資料蒐集等進行研究，並藉由研究結果給現有軟硬體產商提出未來競爭優勢之建議。 本研究建議: 本研究透過各學者所提之先後進優勢比較，並利用Hamel(2000) 的新事業發展模式四大要素，來比較兩個個案在先後進優勢與事業經營策略，並以此兩個個案來看後進者具有那些競爭優勢。 本研究發現結論如下: 1. 在先後進優勢與事業經營策略之比較下，以此兩個個案看來，後進者修正了先進者所犯之錯誤，並有學習及鎖定策略的目標，較先進者有優勢。 2. 在進入時機上，在市場快速變動時，由於先進者尚未建立產業標準，故很容易被後進者取代，而在動態賽局環境下，能隨機應變的後進者更有優勢。 3. 除了先後進優勢，事業經營的策略也主宰了公司的走向及成功與否的主要關鍵因素，先進者縱有品牌網絡優勢，但策略錯誤，也反而被網絡優勢所害，在網路時代被大量散播產品或公司形象劣勢，造成負向循環。 4. 先進者研勤公司也因急於在2009上市，推出過多產品線，反而造成本身資源不匹配，無法支援產品更新，無考慮到公司資源，並作最適分配。 5. 其他先進領導導航機品牌，更是陷入管理惰性，過度依賴過去成功經驗，面對替代性產品出現卻無法跨足軟體市場，喪失新市場機會。 Keyword: 後進者優勢，先進者優勢，應用軟體，事業經營策略

近年基金投資已然成為一般民眾重要的理財工具之一，而投資人最關注的顯然是基金績效的好壞，以及前績效好的基金在未來能否持續先前好的績效表現。因此本論文主要探討台灣的開放式股票型基金之績效、基金績效的持續性，以及投資人買賣基金的行為與基金績效之間的相互影響。論文第一部份是從隨機變數的觀點評估台灣的開放式股票型基金其夏普指標績效值，第二部份則以一般化的馬可夫模型－「漂移者—停駐者」模型評估基金績效持續性的動態行為，第三部份討論投資人的現金流量和基金績效之間的關聯性。 在第一部份的實證結果中，我們認為過去對夏普指標高的基金其績效較佳之想法必須修正，因為從隨機變數的觀點衡量基金的夏普指標值時，所有基金的績效均不顯著異於0。若與市場指數的夏普指標相比，並非所有基金經理人都能打敗市場，雖然以五年評估期間衡量基金績效時，有半數以上的基金其績效顯著優於市場指數，但在二年評估期間下只有極少數基金的績效顯著優於市場。第三，以拔靴法模擬基金的小樣本夏普指標分配時，仍然無法找到基金績效顯著大於零的證據。整體而言，本部份的研究認為從隨機變數的觀點衡量基金的夏普指標績效時，台灣的開放式股票型基金其績效超越市場的證據並不強。 第二部份以「漂移者—停駐者」模型衡量基金績效的動態持續性之實證結果，我們發現整體基金市場具有某種程度的績效持續性，但績效持續性的強弱程度隨著績效組別的不同而有差異，表現最佳與最差兩組基金的績效持續性高於績效中等基金，但整體基金的績效持續性並不很明顯。另外，績效最差組別的停駐基金比率為各組中最高，代表該組別基金的績效持續性較強。第二，基金績效持續性因績效指標的不同而有差異，主要差異反映在各績效組別裡停駐基金比率的估計。第三，「存活偏誤」的確對基金績效持續性的結果有影響，但主要影響反應在停駐基金比率的估計，而非績效漂移基金的轉換機率。第四，以概度比檢定驗證單純馬可夫鏈模型與「漂移者—停駐者」模型對資料的配適程度時，發現「漂移者—停駐者」模型較適合分析台灣開放式股票型基金的績效持續性。 就第三部份基金績效與投資人現金流量的討論，第一，實證結果支持台灣的開放式股票型基金其績效具有持續性，但整體市場的績效持續性並不顯著，其中季資料下基金績效的持續性證據最強，此部份與論文第二部份的結論一致。第二，前一季績效佳的基金在下一季能吸引投資人較多的現金流量，但是放入市場報酬率作為解釋因子後，我們發現投資人的現金流入隨著市場報酬率的上升而提高、隨著基金報酬率的增加而減少，因此投資人買賣基金的主要考量似乎是以市場整體走勢為主，而非基金前期績效。第三，投資人買賣基金的活動對基金後續績效並無影響，這可能是基金經理人的持股比率高於法令規定，或是投資人買入贖回基金的活動對績效的影響通常在數日內即已反應完畢。最後，討論經理人的流動性交易及訊息交易對基金後續績效的影響之前，我們發現基金前期績效的持續大約維持兩個月，但是加入流動性交易及訊息交易作為解釋變數後，基金績效的持續性減弱。 / Mutual funds have been a popular investment vehicle in recent years regardless of the growth of fund assets or numbers of beneficiaries. What investors mind are that whether mutual funds can provide higher return than others, star managers can persist previous dominant performance. For the reasons, we try to examine the performance of Taiwan mutual funds by Sharpe ratio index from new insights, and study mutual fund within best performance group can maintain antecedently superior performance. Finally, we attempt to investigate the relationship between fund performance and fund flows of open-ended stock fund in Taiwan. 1. We analysis the statistical distribution of the Sharpe ratio in Taiwan Mutual Funds developed by Lo(2002) and explore fund performance. First, we construct the confidence intervals of Sharpe ratio of Taiwan stock funds under different assumption for the return-generating process is independently and identically distributed returns (IID) and Non-IID but stationary, then, annualize Monthly Sharpe ratios by Time Aggregation technique. To avoid small sampling errors, we utilize bootstrap sampling conception to simulate the small sample distribution of Sharpe ratio of stock funds. We find that (1) there are not significant evidences that mutual funds in Taiwan have superior performance than riskless rate or market returns in several conditions. (2)By Bootstrapping sampling technique, we still cannot find stock funds have comparatively better performance than market indexes from empirical result. Accordingly, we believe that the usual methods about Sharpe ratios must be modified. That is, a mutual fund with higher Sharpe ratio is not necessarily a good performance, absolutely. Cause, Sharpe ratio index is not a constant, but a random variable, and we must build up its interval estimation and then test if there are significant differences between funds performance. Consequently, we argue it is relatively important to construct the performance-ranking system of mutual funds similar the bond credit-rating. 2. We employ the mover-stayer model to study the dynamics of performance persistence of mutual funds in Taiwan. This model provides us more detailed information about and help us further understand the nature of mutual fund performance persistence. We find (1) that there exists certain degree of persistence in mutual fund performance. Such persistence is, however, not very significant. It is because most funds are mover funds with unstable performance rather than stayer funds with consistence performance. More interestingly, funds within the best and the worst performance groups have more persistent performance than those within the middle performance group. It implies that in view of the previous mediocre performance, fund managers within the middle group have strong intention to improve their future performance. In addition, the fact that the worst performance group has the highest proportion of stayer funds implies that losers are more persistent than winners in Taiwan mutual fund industry. Overall, mutual funds in Taiwan have only weak performance persistence. (2) that consistent with the literature, the degree of persistence in performance is dependent on the performance evaluation criteria. It seems that this difference of degree of persistence is reflected in the estimation of stayer fund proportion, not in the estimation of the transition probability matrix of mover funds. (3) that there exists survivorship bias in our study. It mainly influences the estimation of stayer funds proportion, not that of the transition probability matrix of mover funds. Having said that , we believe that this bias will not alter the important conclusions of this article. 3. This part studies three important issues including the performance persistence of mutual funds, the relationship between mutual fund performance and investor fund flows, and the influence of investor fund flows on the performance of mutual funds. Our analyses are based on the data of mutual funds in Taiwan with three different frequencies that include monthly, quarterly, and yearly data. The methods we utilize to perform the analyses are those from Gruber (1996) and Edelen (1999). There are three main findings in this article: (1)During the sample period from 1996 to 2004, the evidence on the performance persistence of mutual funds in Taiwan is at best weak regardless of various risk-adjusted models and data frequencies. In sum, mutual funds in Taiwan do not perform persistently no matter how their performance is measured. (2)We are not able to discover a significant relationship between mutual fund performance and investor fund flows based on monthly data. This result is not consistent with that of Gruber (1996). However, this relationship becomes stronger if we look at quarterly data. In addition, the most interesting thing is that it seems that it is the quarterly stock market return that derives most of investor fund flows rather than the quarterly mutual fund performance itself. This result implies that the key factor for investors to decide whether to invest more capital into mutual funds is the overall market performance. In other words, the market sentiment may be the most importance factor that induces investors to purchase or sell mutual funds. (3) In contrast to the results of Edelen (1999), the liquidity-trading of fund managers induced by investor fund flows does not have a significant adverse effect on fund performance. Interestingly, the contemporaneous information-trading of fund managers has significant negative impact on fund performance while that in the previous month actually improves fund performance. Furthermore, the performance persistence normally lasts for two months but it diminishes when we incorporate both the liquidity-trading and information-trading of fund managers into the regressions.

隨著智慧型手機普及，大量行動應用程式(Apps)近年如雨後春筍般的出現，然而在大量且功能間相似的App中，如何脫穎而出實為值得探討之議題。 本研究依據先進者優勢作為理論基礎，並延伸探討產品特性及行銷策略對先進者優勢維持之影響，透過檔案分析法針對目前市面上數個成功的App進行個案研究，並同時對功能相仿的App進行交叉個案分析，期望歸納出能領導各種類App成功的方法。 本研究蒐集自期刊論文、相關書籍、報章雜誌及網路文獻之資料，經個案分析之研究結果如下： 1. 市場的先佔及高轉換成本為App先進者主要優勢來源；而較低的成本、市場不穩定性及先進者可能失誤，則為App後進者主要優勢。 2. 較佳的產品功能與產品創新能力，或較能提供更多附加價值之App，對App先進者優勢的維持有正向之影響。 3. 不同種類的App在先進者優勢之維持上略有差異，簡要歸納如下 (1) 遊戲類：受先進者優勢、產品優勢及行銷策略影響甚鉅，快速先占市場，並擁有良好產品功能及完整行銷策略較易帶來成功。 (2) 工具類：透過較佳的產品功能、產品品質與產品創新來維持先進者優勢，才能保持長期競爭力。 (3) 娛樂類：先進者優勢與產品優勢同等重要，快速先占市場將有助於發展與競爭力維持。 (4) 社交類：深受網路外部性之影響，故快速先佔市場並持續滿足使用者需求，才能避免被後進者淘汰。 / As more people use smart phones, the number of mobile applications (Apps) is increasing rapidly. However, with so many similar Apps, how Apps can stand out from competing products is an important issue. This study adopts theories related to First-Mover Advantages, Product Advantages and Marketing strategies to develop a general framework for analyzing factors that affect the success of first movers. We chose several well-known apps and used document analysis to analyze the secondary data collected from the Internet, newspapers, magazines, books, etc. Our major findings are as following: 1. Market preemption and high user switching costs are the main source of advantages for first-movers. Lower development costs, risks and the chance to avoid failure are the main source of advantages for the follower to succeed. 2. Better product functions and innovative features have positive effects on keeping First-Mover Advantages. Meeting customer needs and providing more added values also help maintain the advantage. 3. Different factors exist for different types of apps. Product advantages and marketing strategies are keys for Games Apps; app functionality, product quality and innovative features are important for productivity tools; first-mover and product advantages are important for entertainment apps; while network externality is the most critical one for social networking apps.

當身處一個競爭激烈的行業，企業想要保持發展，就必須與時俱進，積極創新。但企業應該從哪裡找到創新的機會？除了技術和產品之創新，越來越多企業開始關注商業模式的創新。過去，對商業模式創新的討論大部分集中在企業的內部系統活動改造，或是期待從開放創新中尋找機會。本研究嘗試把商業模式理解為一種敵我對應關係，從主流企業與後進者的攻防戰中理解創新的調適過程。通過分析「非主流」的後進者如何回應主流設計，並由主流企業之迷思理解後進者如何找出商業模式創新的可能。本研究發現，商業模式創新的本質是動態的，而其過程是調適的。後進者可以由主流企業建構商業模式之迷思中，找到自身商業模式創新的諸多樣貌與調適的巧思。 / In an industry that faces intensified competitions, firms need innovate constantly and timely so as to maintain steady growth. But where could firms identify opportunities for innovation? In addition to the innovation of technologies and products, more and more firms pay attention to business model innovation. Previously, our understanding of business model innovation is limited to firms’ business activity systems, or to seek opportunities from open innovation. This thesis attempts to consider the business model as a kind of responsive process between rivals; and to analyze the adaptation of business model within the defensive process between the mainstream firms and the second mover. By analyzing how the non-mainstream player may respond to the evolving dominant design, it is posisble to recognize the myths of the development of mainstream business models. This research suggests that business model innovations are dynamic in their nature and adaptive in their developmental process. The second mover could identify various patterns of new business models and conceive creative adaptation from the mainstream firms’ myths in building their own business models.

Poser la question du divin chez Aristote, c’est déterminer à quelle question la conception aristotélicienne du divin est censée répondre. L’examen méthodique de l’intégralité du corpus aristotelicum et, tout particulièrement, des trois textes dans lesquels Aristote place l’étude des réalités divines au centre de son enquête (Physique, VII-VIII ; De Cœlo, I-II, Métaphysique, Lambda) permet de formuler deux conclusions principales. En premier lieu, il apparaît clairement que la question du divin n’est pas, aux yeux d’Aristote, de nature théologique, mais archologique. Nulle part, en effet, l’étude du divin n’est menée pour elle-Même ; elle s’ancre, au contraire, dans un examen explicitement dédié aux principes premiers de la phusis ou des ousiai. La conception aristotélicienne du divin et des dieux est ainsi le produit d’un examen méthodique des êtres premiers et des principes, examen grâce auquel Aristote espère produire une détermination rigoureuse du mode d’être du principe en tant que tel et résoudre, par là même, certaines apories relatives à la question de l’archè. En second lieu, il convient de noter que les principaux textes dévolus à l’étude des êtres divins se distinguent les uns des autres par des nuances méthodologiques significatives. Selon que la question du divin prend naissance au sein de la science naturelle ou de la science des substances, selon qu’elle appartient à la physique ou à l’ousiologie, la preuve de l’existence des réalités divines, de même que la description de leur nature et de leurs fonctions, font l’objet de formulations diverses, toutes inféodées à la logique conceptuelle de la science qui les rend possibles. En somme, chaque examen des réalités divines se distingue par sa tournure singulière, qui n’est autre que le produit de la régionalisation des discours, c’est-À-Dire de leur adaptation méthodologique aux outils de la science qui les engendre. / Studying the question of the divine in Aristotle implies to determine to which problem the Aristotelian conception of the divine is supposed to answer. Two conclusions can be drawn from close examination of the corpus aristotelicum in its entirety, and particularly of these texts in which the study of divine realities is Aristotle’s major concern (Physics, VII-VIII; De Cœlo, I-II, Metaphysics, Lambda). In the first place, it clearly appears that, according to Aristotle, the question of the divine is not a theological question, but an archological one. Indeed, nowhere Aristotle studies the divine beings in order to explore deeply the nature of the gods, but rather with the intention of investigating the first principles of phusis and ousiai. The Aristotelian conception of the divine is thus the consequence of the detailed examination of the first principles, thanks to which Aristotle thinks he will be able to define precisely the nature of the principle qua principle and then to solve some aporia about the archè. In the second place, it is worth noting that each of the three main texts in which Aristotle develops his conception of the divine is characterized by slight but significant differences in method. Depending on whether the question of the divine belongs to the science of nature (physics) or to the science of ousia (ousiology), the demonstration of the existence of divine beings and the description of their nature and causality are expressed in different ways, in accordance with the concepts employed in each science. In short, each investigation about divine beings is characterized by its singular form, which is the product of the regionalization of each inquiry, i.e. of its methodical adaptation to the conceptual tools of the science to which it belongs.

The digital payment industry has become one of the fastest evolving markets in the world, but in the wake of its rapid advancement, an ever increasing gap between academic theory and the actual reality of this market widens - and especially so when it comes to entry theory. It is widely acknowledged that the world is moving towards an ever more homogeneous economy, but despite the fact that payment preferences differ greatly from country to country - research on this subject continues to revolve mainly around localized efforts. But as historical inequalities between poor and rich societies continue to dissipate - learning from nations at the forefront of technological advancement increases the likelihood that the developed strategy becomes applicable to an increased number of countries. By selecting a nation most conducive to technological growth, the purpose of this report is to map the present dynamics in its digital payment industry using both recent and traditional market entry theory. However, studies geared towards globalized strategy formulation cannot be assumed as having guaranteed access to internal company-data at all times. So in order to facilitate such studies, the level of dependency on primary data required for conducting such research needs to be understood first, which is why the work in this report is constrained strictly to data of secondary nature. This, not only to further map the characteristics of this market, but also to see how open the market is to public inspection. Ultimately, the academic contribution becomes that of providing a road-map towards adapting currently available market entry theory to suit the rapidly evolving conditions of the digital payment industry from a global perspective and, when failing to do so, the aim is to also explore avenues for further research towards this end goal.
