本文試圖以兩個層次來分析多頻道競爭市場，第一是以壟斷性競爭市場(monopolistic market) 的角度切入觀察整體的頻道市場，發現頻道間的競爭增加對於節目的多樣化並沒有很大的助益，多數頻道仍有節目類型高度集中的趨勢。第二，以家族頻道 (multi-channel operators) 的層次進行分析，家族頻道內的節目垂直多樣性不高，且有經營專業性頻道，朝向分眾市場的趨勢。而以水平的節目多樣性來看，家族頻道內確有強調節目差異化策略，比起整體頻道而言其節目的水平差異化較大。

In this article, 1 tried to analyze the multi-channel market in two different approaches. The first approach is to analyze the channel market in the monopolistic market point of view. I found that the increasingly competitive environment between different channels dose not necessarily improve the diversities of program. Instead most channels still tend to have similar program type. The second approach is to analyze the channel market in multi-channel operator point of view. In the multi-channel operators the vertical diversities of program is not high and they tend to produce professional channels. The tendency is toward the segment channel market. In observing their horizontal diversities, the multi-channel operators have the strategy of emphasizing the diversities of program, greater than the whole channel market.
