Wu Cheng-chi, associate professor of the graduate school of economics at National Taiwan University, says, if prices are determined by supply and demand as classic economic theory tells us, then one must look at the level of profits and competition in the market.
「物價確實是由供需狀況決定的，但廠商是不是有不合理的利潤，卻要看市場的競爭是否充分而定」，台灣大學經濟研究所副教授吳忠吉表示。
