Opposite uneconomicDefinition economy noun 1 SYSTEM [C] the system by which a country produces and uses goods and money the German/US economy a global economy 2 USING LESS [C,U] when someone or something does not use much money, fuel, etc The car's design combines comfort with economy. (UK) We'll need to make some economies when I stop work.economic benefit 交易中的收益，比如如果是一个公司或个人做了一笔生意就是这个。主要是讲赚钱了。economy benifit 经济生活中的好处，如果是一个国家的的经济就说这个了。应该说，涵盖的方面更多，层次也更高一些。至于benefit 和 perfomance一个是收益一个是表现。e-performace是表现 表现有好有坏。严格的说不能翻译成“效益”e-benefit 则是好处。可以说是经济效益。
