Actually, it seems that if the modifiers would set the space yard rate to less than 2000 resources per turn, it is set to 2000 resources per turn. When I have 40M population or so I have a -60% modifier. The modifier is still there after building the space yard, but the production still makes a dramatic jump. Thus, bonuses apply quite well, but only limited penalties actually apply in that the space yard constructs 2000 instead of the advertised 2500.
