The analysis of economic environment is the basis of well managerial decisions for enterprises. However, the relationship among economic variables in the real world is a kind of dynamic complexity problem. Economics usually take advantage of mathematics to solve this kind of problem. Therefore, it will be very difficult for business administrators to analyze the long-term dynamics competitive. This study integrated system dynamics thinking and dynamics of strategic maneuvering to build a systems feedback model of dynamic competitive environment, which can be used to analyze the long-term dynamics of competitive variables under different scenarios, including the dynamic thinking of growth and core competitive strategy. Linked with balanced scorecard interface, the model will become a decision support system of dynamic competitive analysis, which can provide business administrators with the analytic tool of dynamics competitive environment to improve their decision qualities concerning finance, production, and marketing.

This study discusses competitive interaction between smartphone manufacturers by the view of dynamic competitive. Focusing on 20 brands which have entered Taiwan smartphone market, this study collected the time of innovation behavior (technical innovation, appearance innovation and marking innovation) from Internet and smartphone magazine. There are five variables in this thesis which include firm country, firm diversity, firm outsourcing, firm age and firm size, and to the three innovation behaviors, (technical innovation, appearance innovation and marking innovation), this study proposes fifteen hypothesizes. In order to explore the relationship between firm characteristics and competitive responding speed. Using the Cox proportional hazard model in survival analysis, this study shows the result that the manufacturers respond faster while they have lower diversity and large scale.

本研究使用中國大陸製藥工業之上市公司及部分非上市公司1999年至2010年之財務與非財務資訊做為樣本觀察值，探討研發密集度在企業競爭與經營績效中所扮演的角色，研究結果顯示企業專利佔有率與經營績效具有顯著正向關係，而企業專利佔有率的變動數與企業產值排名的變動情形亦呈現顯著正向關係，顯示研發密集度與企業競爭優勢息息相關。本研究並以前項結果作為基礎，進一步分析產業內績效領先企業群專利佔有率異常上升時，競爭企業是否會透過提升研發密集度或是行銷支出密集度來做為因應，而研究結果指出領先企業群之專利佔有率異常上升時，會導致研發密集度較高的企業異常提升其研發密集度，並導致研發密集度較低的小型企業大幅提升行銷支出。本研究結論專利對企業經營績效具有正向影響，並能替企業帶來競爭優勢，同時企業亦將專利視為競爭優勢之主體，對於競爭者的專利策略會予以因應。本研究建議企業在形成策略時，應綜合考量產業結構、核心資源以及競爭者的競爭性行為或可能的回應。 / The present study investigates the role of granted patents in determining industry competition and operating performance. The sample consists of Chinese public and private companies in the pharmaceutical industry from 1999 to 2010. The findings show that the quantity of patent is positively associated with operating performance and that the change of patent count is also positively associated with the ranking of market share. Moreover, the results show that the change of patent counts of leading companies has a positive impact on followers’ innovation activities and marketing activities. Overall, the evidence suggests that patent plays an important role in company competition and that companies response to the R&D(patent)strategy of their competitors in the market.

便利商店自1979年由統一企業引進台灣，經過三十餘年的發展，目前為一寡占市場，市占率由連鎖超商體系的統一超商(7-ELEVEN)、全家便利商店、萊爾富超商及來來(OK)便利商店占據了將近九成九的市占率，而台灣的便利商店有其特有的產業生態，即現今便利商店中較具規模的品牌，都與上游的品牌商具有相當緊密的連結。而這樣的產業現況，讓台灣食品品牌商與便利商店之間略有體系對抗的意味存在，若將品牌商與通路之間視為一個整體，假設通路商為品牌商的點，其競爭行為即為「多點競爭」。無論對上游的品牌商或是下游的通路商，這種形式的緊密連結使其競爭合作關係的可能性與複雜度也比在單一產業中競爭來的複雜且多元許多。 　　本研究將品牌商與通路商視為一體，觀察其：(1)上下游相互協助的狀況是否存在；(2)上下游規模是否影響其競爭策略的擬定；(3)相互容忍的現況是否存在，採用田野調查法收集資料後，透過內容分析法中質性研究的方式，並且以動態競爭的觀點，對台灣便利商店與品牌商之間的特殊結構做分析，並將資料利用不同的觀點解讀，試圖探究其兩者之間的競爭行為是否具有相互影響的現象，並配合現有的客觀資料，嘗試說明便利商店與品牌商之間的互動關係與成因，也嘗試用品牌與通路規模當作分析的變項，驗證其是否為影響便利商店與品牌商競爭行為間的因子。 　　而結果也與預期相似，(1)品牌商及通路商有相互協助的現象存在。(2)上下游的規模也確實影響其策略的制定，品牌規模越大，越容易作為協助促銷的對象；通路規模越大，也越容易作為推廣品牌的點。(3)多點競爭的相互容忍現象存在於此產業相當多的品類當中，尤其是寡占的品類市場。

傳統商學院論文所探討的競爭態勢多半聚焦於廠商間的競爭，著重組織對組織、集團對集團的互動過程，本研究提出競爭的另一種型態，描述由個體所組成的非正規群體(駭客)與組織集團(廠商)的競爭，以病毒與防毒軟體廠商的互動過程為例，透過歷史的描述呈現電腦病毒、防毒廠商、戰爭三個構面。 本研究以病毒為描述主體作為邪惡的反方角色，並且深入探討其背後的核心操控者：駭客們的動機與行為，之後將相對應的正方角色：防毒公司拉進來，詮釋病毒與防毒軟體的互動過程。最後，整理出在歷史的演進之下，病毒/防毒戰爭過程中的脈絡與攻防特性，並演譯歸納出病毒的五大創新特點：技術Deeper、影響範圍Bigger、傳播速度Faster、病毒行為Smarter、產業結構Robuster。 綜觀國內外商學院論文，尚無類似論述，其突破性貢獻有三：其一，本研究提出以病毒負效用的特性作為創新的論述，至今無人提出，雖可議卻也空前；其二，本研究突破過去討論病毒相關議題僅考量單項變數的限制，以全面性的系統觀點探討其特性；其三，此類議題的相關論文處理方式多半以量化、實作亦或次級資料整理為主，本研究則進行深入訪談的田野調查。 基於創新來自於邊陲的概念，本論文希望排除道德的限制，單純從特性上加以考量其創新，並非鼓勵或褒揚之意。希望提供企業以另一個層次的角度思考本文所提出之創新觀點，應用於研發管理、創新管理、行銷管理、策略管理等領域，興許能有不同的創新解決方案。 / Most papers from the traditional business school discuss the competitions among manufacturers, and focus on the interactions between organizations and between groups. However, in this paper, we propose another type of competition - the competition between the hacker (composed by the individuals or non-regular organization) and the manufacturer (organizations or groups). Here, we take the interaction between virus and anti-virus software manufacturers as example to describe the 3 dimensions among computer virus, anti-virus software manufactures and their contests. In this thesis, we take virus as the evil side and expect to dig out the motivation and behavior of the hackers, and then we take the anti-virus software manufactures as the counter side to discuss the interaction between virus and anti-virus software. Finally, we sum up the 5 innovative characteristics of the virus: the skill is deeper, the incidence is bigger, the spreading speed is faster, the virus behavior is smarter and the industrial structure is more robust. In this thesis, there are 3 unprecedented distributions: first, we propose the innovative concept by using the disutility characteristic of virus; second, we breakthrough the restriction that only taking the single parameter into consideration, and we take the total system viewpoints into consideration to discuss its characteristics; third, instead of quantification, experimentation, and sub-data collection, we do the research through the interview and the field work. In this thesis, we wish to eliminate morals constraints, just consider its innovative concept, and not mean to encourage or commend it. Furthermore, we expect to provide the enterprises another way to think about this new concept, and apply it in research and development management, innovation management, marketing management, strategy management, and so on. We believe that there will be some other different innovative solutions.
