1、This idea that (sort of Western companies that are tax efficient are exploiting these places

rather than bringing inward investment to them.)第一个that指括号中的部分，即是This idea

的内容。括号中内容作This idea的同位语；

2、This idea that sort of Western companies that （are tax efficient） are exploiting these

places rather than bringing inward investment to them.第二个that指括号中的部分，修饰sort

of Western companies（一些西方公司），作主语的修饰成分，即为主语从句。

3、sort of Western companies are exploiting these places rather than bringing inward

investment to them.

其实这句话的主干如上，这是把修饰语以及同位语去掉后的结果。

rather than = instead of 而不是

sort of Western companies 作主语

are exploiting 作谓语

these places 作宾语
