經由經濟分析的結果，本文發現市場結構、廠商市場占有率，以及產品性質等是影響獨家交易市場競爭效果的重要因素，可做為獨家交易管制初步檢定的標準。市場進入障礙、特許權、品牌外部性強度、規模經濟、範疇經濟、市場需求彈性、產品品牌數、採用獨家交易的目的、新進廠商與小廠商是否採用獨家交易等九項因素，則可作為獨家交易反競爭效果檢定的基礎。 利用建立規範準則，驗證公平會曾經處理過的獨家交易個案，發現高鳳公司案、牛農公司案與弘通公司案，未能量過初步檢定。中油公司潤滑油案與柯達公司案，則通過初步檢定後，進一步研究其實質競爭效果，顯示柯達公司案，反競爭效果較低，不應加以管制。相對的，中油公司潤滑油案，則顯示其有嚴重反競爭效果的可能，主管機關有加以禁止之必要。

Based on the results of economic analysis, this paper finds that the important factors influencing market competitiveness of exclusive dealing include market structure, market shares of firms, and product differentiation. These factors could serve as the preliminary examina­tion standard in regulating exclusive dealing. Next, we could examine the anticompetitive effect of exclusive dealing on the ground of nine factors: barrier to entry franchise, strength of brand externality, economy of scale, economy of scope, market demand elasticity of price, number of brand, purpose of adopting exclusive dealing, and new and small firms using exclusive dealing. Employing the proposed criterion and past cases processed by the Fair Trade Commission, we find that two of the five cases pass the preliminary examination. They are Chinese Petroleum Corporation and Kodak Corporation. In the ensuing examination of substantial competitiveness, the Kodak Corporation case shows relatively low anticompetitive effect. Thus, no surveillance is necessary. In contrast, the lubricating oil case of Chinese Petroleum Corporation shows severe potential of anticompetitive effect. The Fair Trade Commission should intervene and ban its trading.
