The endgame of relentless merger activity, after all, is a few companies in each industry owning their markets and having unfettered opportunity to do and charge whatever they like.
请问：
修饰语owning their markets与having unfettered opportunity是不是均可觉得等于定语从句？如果是定语从句的话，那样其先行词是companies还是industry或是a few companies in each industry这个整体呢？
判判定语从句的先行词是不是得用逻辑剖析呢？
主语为the endgame，其补语为a few companies，二者都是名词，则二者应存在全等的关系。从句意上看，the endgame应指形成的某种局面，即指a few companies own their markets and have unfettered opportunity…。从语法上剖析，the endgame就是指a few companies，而the endgame与a few companies应该不是全等关系。这个句子是标准、正确的句子吗？
句子语法剖析不能离开逻辑剖析。网友已经在（3）中意识到在逻辑上，主语endgame应该是一个局面，即a few companies own...and have..., 那样表语就不可能是a few companies后接定语结构，而只能是that从句或动名词复合结构。本句中的owning...和having...为动名词短语，前面的a few companies为动名词的逻辑主语，一同构成动名词复合结构作表语。
因此，网友的问题（1）和（2）其实是没有的，是错误剖析致使的疑惑。
本句可以改为that从句作表语，仅需将owning和having改为谓语动词形式即可。
