划分一下语法成分,英语语法问题

Yet,even more important is the long-term significance this new effort has for the country's ongoing urbanization,which will be a major driver for economic growth and transformation over the coming years.
首先,为了划分成分更方便和利于理解,原句结构可以变化为：
Yet,【 the long-term significance 主语】【this new effort has for the country's ongoing urbanization 定语从句,省略关系代词】【is主句谓语】【 even more important表语 】,【which will be a major driver for economic growth and transformation over the coming years非限制性定语从句】.
原来句子之所要用倒装结构,是由于句子结构的需要——后面带了很多定语,以及非限制性定语,修饰主语及其定语.
祝你开心如意!
再问： 为了结构平衡倒装，将表语前置一般不是需要一个形式主语么？
再答： 你问的很在理！ 其实，你看透了的话，表语前置的根本原因之一，还就是将前面的名词主语后置，以便它与后面的很长的定语修饰成分顺畅连接。但并不是所有表语前置都需要形式主语。 例如： So exciting and thrilling was the film that we had seen it three times.固定结构搭配导致倒装，强调形容词。 The same helpful is a book which is about how to understand English sentences by analysing sentence-patterns.
