Mmmm, there are a few examples of prefab high-rises that have gone up in weeks or months. I guess high-quality is something of a shifting bar, but if you prefab all the pieces, build them at volume, and have enough demand to justify that volume, it's been done before. That's how all the plattenbau (ugly commie concrete towerblocks went up in eastern europe) got done. I figure the problem is basically politics. Liberal democracies typically do planning by asking 'stakeholders' (e.g. business owners, home owners, etc) what they think about proposals. Since you're asking the stakeholders in an asset class whether or not you should build more of their asset, usually nearby, the answer is usually a lawsuit.

Do you have any links on that? Most of the reference I found, Pre-Fabs only works for about 10-15 Floor buildings.

  It's kind of a genre: watch like, https://www.youtube.com/watch?v=AhLk7L1B_fE https://www.youtube.com/watch?v=AhLk7L1B_fE, and you can see a bunch of others in suggested links. From what I gather, a industrial-scale air-conditioning unit company basically broke the space open, since they were essentially doing large scale prefab construction already. Just think about it from first principles. You can build large structures out of prefabricated parts, and if you design the parts sufficiently well, it's possible to fit them together fast. The problems are stuff like weight (transport costs start to dominate), volume (if there's not enough demand for skyscrapers, you don't want to be sitting on a skyscraper factory), etc. In East China, they have a lot of structural advantages: a huge, hugely dense population, a government that loves big construction projects, a massive housing market, a great deal of experience in doing civic infrastructure fast, etc.
