帮忙分析一下这句英语的结构
An important factor in a market-oriented economy is the mechanism by which consumer demands can be expressed and responded to by producers.

an important factor in a market-oritned economy 主语
谓语(系动词) is
表语 mechanism
in a market-oriented economy 介词短语 修饰factor
mechanism 后面是一个定语从句 修饰 mechanism

an important factor in a market-oritned economy (主语) / is (谓语) / the mechanism (宾语),后面是宾补吧
by which (这里的which 指代 the mechanism)
consumer demands can be expressed and responded to by producers
expressed 和 responded to by producers
不好意思,我不知到这些语法术语,但是这样理解是没错的.
