香港消委会发现,在香港通货收缩的情况下,出版商仍增加课本的售价。出版商解释,加价原因除了纸价上升外,亦要投入大量资源制作辅助教材及赠送教具。但消委会认为,给予学校的辅助教材的成本转嫁至家长,并不合乎用者自付的原则。 The Hong Kong Consumer Council has found that publishers still increase the selling price of textbooks in the event of a deflation in Hong Kong. The publisher explained that in addition to the increase in paper prices, the reasons for the fare increase should also devote substantial resources to making auxiliary materials and teaching aids. However, the Consumer Council considers that it is not in the principle of user-pays to pass on the cost of supplementary teaching materials to schools to parents.
