Well, it's not exactly possible for me to talk much about it since I work in financial analysis, but there's a bit of that in these articles. http://www.ft.com/intl/cms/s/0/381ba69a-01e3-11e4-bb71-00144feab7de.html#axzz38udN1B6j, http://www.businessweek.com/articles/2013-06-27/china-profit-rise-masks-state-enterprise-weakness
Only able to read the 2nd source, which leads to an interesting point(albeit perhaps not one that really discredits yours).
Namely, if there whole point is stimulus, wouldn't it possibly matter less if their profits grew? If they're providing economic stimulus mind you.
Then you have the fact that high-tech foreign firms working in China typically form JVs with a state-owned enterprise, with agreements to transfer production technology. The state-owned enterprise then gets the blueprints and then takes separate orders from domestic buyers. It's all in line with China's stated policy of nurturing industrial champions (as with most other East Asian states).
Interesting to note.
