To take another case, construction of power transmission lines is a "natural oligopoly" situation. Taipower already has an island-wide power transmission net. Based on the principle that there should be minimal duplication of effort, which would be a waste, is it necessary to open this market to allow private investors in?
再說，要架設電線的輸電業有「天然寡佔」性質，台電既已有環省輸電網路，站在不要重複浪費資源的立場，還需要開放市場讓民間加入嗎？
