State controlled or National corps (Little Upsilon)

Ummm, what are the differences between these?

I've had a look around and cant find anything to help me. :/

Nationalised corps are protected from bids. This is the only difference. Anybody could theoretically bid on any state corps you have against your wishes, although this is unusual.

Nationalisation is useful for any corps you have that supply products your country needs. It is also used to protect strategic and plutonium/uranium/weapons grade uranium corps, plus other weapons and ammo corps.

Wonderful, thanks for the help.. :D

So when one is new in the game it is good to have a mixture? What about the tax rate on national and state? Any difference? Or you choose?

0 for all state corps IMO. If someone invests in you're country,its good to have a tax of 0 so they will stay.

National corps,tax as high as you want.I think for Strategic corps,make sure to tax em very high so you recoup money on the things they build.
