Probably some amount but I reason this would be much harder. You must pay workers where they live and buy resources from where they are produced. It's easier to offshore a made up entity like a corporation than a bunch of people and their hardware.

If tax law provides the incentives, companies can do all sorts of gymnastics to obfuscate those two things. There is always a loophole if you look hard enough for it.

Pay workers where they live? Why not hire them through an offshore firm that pays them as international contractors?

Buy resources where they are produced? Buy the rights to the resources from an offshore company who owns the IP rights to the method of production.

These are convoluted examples but the point is, companies can always add a level of misdirection to fit within a loophole.
