Yang Kuang-hwa, associate professor of the Department of International Trade at National Chengchi University says that many of the products in the cable television market have their own special character and there is limited opportunity for substitution, which leaves a certain degree of monopoly.
政大國際貿易系副教授楊光華卻認為，有線電視市場的商品多帶有智慧財產權屬性，不同頻道節目間的可替代性較低，具有一定程度壟斷性。
