經濟效益

對於增加東涌線的班次，地下鐵路公司某高層說需要考慮經濟效益。We have to consider cost-effectiveness。上星期，一家新的航空公司開幕。該公司說經營長途機業務比短途機更具經濟效益。Running long-haul flights business is more cost-effective than short-haul flights 。對於書展明年是否也延長開放時間，出版商說需要研究是否符合經濟效益。Publishers said they had to study whether or not longer opening hours were cost effective。Cost-effectiveness 是「成本效益、經濟效益」的意思。它是名詞，形容詞是 Costeffective，
即「符合經濟效益、有利可圖」的意思。

其他例子：It wouldn't be cost-effective to bring him over from Sydney just to give a seminar是「從悉尼請他來主持研討會不符合經濟效益」，Banks must be run in a cost-effective way是「經營銀行必須符合經濟效益」。
