|Abstract: ||「網路壅塞」( Network Congestion )，是只要在討論網路議題時都必然要解決的一大問題。對於由網路議題所衍生之「網路外部性」( Network Externality ) 與「網路效果」( Network Effects ) 等主題的探討，也已經藉由許多文獻到相當卓著的見解，因此本文也同樣希望由經濟的角度來討論存在「網路壅塞」或「網路負面外部性」之下，對於網路服務供應商的競爭互動策略將會有何影響。|
沿用Gibbens, Mason, and Seinberg (2000) 的文章所討論的主題與所運用的數學模型，並加以修改，同時由於網路業者所提供之加值服務於今日愈加多元且早已大幅改變人們的生活方式，在網路不可或缺的時代，消費者不只關心網路連線的安定與品質，更重視網路業者所提供之豐富的附加服務；而對網路商而言，在科技突飛猛進的推波助瀾之下，也把合理而可行的網路加值服務視為拓展市占率的途徑之一。所以本文希望進一步呈現在符合某些假設之下，結合消費面與生產面，嘗試由廠商規模、絕對頻寬、相對頻寬、提供加值服務的邊際成本以及消費者與廠商之心理型態等角度，來探討網路服務供應商彼此之間在市占率、定價以及利潤等方面將會如何運作。
“Network Congestion”, as long as the topic of the discussion network are bound to solve a problem; the issues arising from the network of “network externalities” and the “network effect” and other topics discussed by the literature has been quite remarkable insights, but this will also be looking to discuss the economic point of view there is “network congestion” and “network externality” under the For net work service provides will be the impact of competitive interaction strategies.
Follow Gibbens, Mason, and Steinberg(2000) discussed the subject of the article with the use of mathematical models, and modify, and because the network operators to provide value-added services are increasingly diversified and today has long been a substantial change people’s way of life, essential in the era of Internet, consumers not only care about the stability and quality of network connectivity, network operators pay more attention to the wealth of additional services provided; and for network operators, the rapid advances in science and technology in fueling the, it is also reasonable and feasible network to value-added services as one of the ways to expand market share. Therefore, this article hopes to show, subject to certain assumptions, a combination of consumption and production side surface, attempts to firm size, the absolute bandwidth and relative bandwidth, the marginal cost of providing value-added services and the types of consumers and manufacturers of the angle of Psychology the explore each other Internet service providers in the market share, pricing and profits, etc. will be how it works.
