方向性市場競爭行為之研究

現實社會中如水資源、陽光、風力、漁類資源等皆具有方向性的特徵，本文即是探討廠商在方向性市場上的區位競爭行為。主要發現如下：(1)無距離限制時，對後進者較為有利；(2)隨著距離限制的寬嚴程度不同，對先進者和後進者有不同的影響，在距離限制較大時，對先進者有利；反之則結果和無距離限制相同，均對後進者有利。所以在方向性市場中，可以訂定規則或規範，扭轉先進者及後進者的相對地位，但在訂定規則時，必須要注意距離限制規範之「有效性」，以免喪失訂立規則之原本用意。

There are several natural resources, such as water, sunlight, and wind, which that have directional characters and display special usage-competitions which are very different from that in non-directional markets. The purpose of this paper is to analyze the location competion in a directional market with a distance constraint. It is shown that a first-mover advantage may result from a strong distance constraint; while a second-mover advantage emerges with a mild distance coinstraint. The policy implication is that the distance constraint in a directional resource should be carefully regulated in order to achieve policy goals.
