I'd wager that some have, and some haven't. There's a tonne of companies all competing with each other within China. Those that are competitive (especially those that receive support, like you say) survive, while the others that don't, struggle in leaner times.

I'm not sure how this looks industry-wide, but I know of companies that are not doing great, due to lack of investment in the domestic market, so surely that applies to FDI.
