What is the meaning of ...不断向产业链的高端提升是发展趋势的要求? I can't quite get the last part of this

专家：这个问题不能一刀切。对于东部的企业，因为起步较早，有一定产业规模和资金积累，所以调整产业结构，提高技术含量，不断向产业链的高端提升是发展趋势的要求。

Can I rewrite the last bit thus:

不断向产业链的高端提升是发展趋势的要求。= 发展趋势的要求是不断向产业链的高端的提升。
发展趋势的要求是不断向产业链的高端的提升。

develop trend 的 demand is non-stop to supply chain 的 high-end 的 increase
= the development trend is towards an ever increasing luxury car market.
I think you are confused about 产业链的高端, is that right?

It may be translated as high level of supply chain. 

I think he want to express that the companies should become the creator, not just the manufacturer.
