Its strategy rests on two beliefs: first, a global product offers economies of scale with which local brands cannot compete, and second, consumers in the 21st century are drawn to global as a concept.
主干:Its strategy rests
主句用了rest on短语。冒号后的first...and second...用以解释说明冒号前的two beliefs,可以看做是该名词短语的同位成分。with which引导定语从句修饰economies of scale。句末的be drawn to表示为...所吸引,as a concept介词短语作global的后置定语,作为概念的全球化,或全球化概念。
译文:公司的策略基于两个信念:首先,全球性的产品能够提供地方品牌无法与之竞争的规模经济;其次,21世纪的消费者认可全球这个概念。
