If you count being locked out of the Chinese markets, I think the number is actually much, much larger than $50B. But that seems to be rather unrelated to hacking? In fact most countries openly or secretly try to lock out foreign owned businesses. If the point is that China does it more than others, perhaps it's true, but it's a lot more complex issue than outright hacking.

I think the hacking and being cut out of domestic markets is fairly closely linked.

If you’ve already stolen the IP, you don’t need to let the foreign business in to provide that service.

Possibly even more widespread though has been the standard practice over the last 20 years of lettin foreign businesses setup shop in China, hacking/stealing all their tech, then the state uses its legal/political resources to make life horrendously difficult for the original foreign business.
